Vybronics is a manufacturer of vibration motors and haptic actuators, in business since 1998. It produces LRA (linear resonant actuator), SMD (surface mount), and coin vibration motors, with production lines in Vietnam and China and sales engineering offices in the USA and China. The company serves product teams that need vibratory haptic feedback or small DC motors, and it offers application engineering support plus custom motor design.

What Vybronics makes

The product line centers on small motors used to generate vibration, spanning several motor technologies and mounting styles:

Motor technologies available include ERM (eccentric rotating mass), Linear Resonant Actuators (LRA), and BLDC brushless.

Where these motors are used

Vybronics tactile actuators generate vibratory haptic feedback in applications such as cellphones, wearables, hearables, display panels, and augmented/virtual reality hardware using HD haptics. The company's coreless DC micro motors are used in applications ranging from drones to smart electronic locks.

Background and context

The use of ERM motors for vibrotactile feedback dates to 1984, when Motorola introduced the BPR-2000 numeric display pager with a 7 mm diameter brush-type cylindrical ERM motor, used to generate a "Silent Alert" as a costly optional feature. Manufacturing technology for coreless micro motors later moved from Japan to China and Vietnam, and motor prices dropped dramatically. Haptic feedback is now expected as a standard feature, alongside newer technologies such as SMD surface mount, coin LRAs, and piezo.

Choosing and customizing

Vybronics states it has experienced applications engineers who can help select the right vibrating motor, or design a motor to meet specific requirements. That makes the site relevant both for teams comparing standard catalog parts and for those needing a custom actuator.

For more detail on specific parts, the site organizes information under Product Information and Customization sections, with contact options for further questions.

Vybronics builds vibration motors in four mounting/connection formats: SMD surface-mount (reflow solderable, supplied on tape & reel), through-hole PCB mountable, spring contact (solderless), and encapsulated/overmoldable. The right choice depends on whether you need automated high-volume assembly, lower cost with higher G force, tool-free field serviceability, or protection in harsh environments.

The four options at a glance

SMD surface mount (reflow solderable, tape & reel)

SMD motors are designed to be placed and reflow soldered directly onto a PCB, and they ship on tape & reel so they can run through standard pick-and-place equipment. Vybronics lists SMD surface-mount as one of its motor technologies alongside coin LRA and ERM types.

Choose this when your assembly line is already set up for reflow and you want the motor treated like any other SMD component. The trade-off noted by Vybronics is that through-hole versions offer lower cost and higher G force than SMD reflow solderable motors.

Through-hole PCB mountable

Through-hole motors mount with pins through the board and are soldered in place. Vybronics positions this option as offering lower cost and higher G force than SMD reflow solderable motors.

Choose it when per-unit cost and vibration strength matter more than automated placement, or when your board design already uses through-hole assembly.

Spring contact (solderless)

Spring contact vibration motors use a solderless interconnection. Vybronics states this "facilitates manufacturing and field serviceability" — meaning the motor can be assembled or replaced without soldering.

Choose it when the motor may need to be swapped after assembly, or when you want to avoid a soldering step in production or repair.

Encapsulated / overmoldable

Encapsulation is offered to facilitate mounting and use in harsh environments. Choose it when the motor will be exposed to moisture, dust, or mechanical stress that a bare motor wouldn't survive.

How to decide

• High-volume automated PCB assembly → SMD on tape & reel.
• Lowest cost and strongest vibration, hand or wave soldering acceptable → through-hole.
• Serviceability or solderless assembly → spring contact.
• Harsh environment or rugged mounting → encapsulated/overmoldable.

Note that the mounting format is separate from the motor technology. Vybronics offers ERM, LRA (linear resonant actuator), and BLDC brushless types, and LRA options — both coin and rectangular — are described as best for haptic feedback with low drive voltage and current, high vibration force, and a required driver IC. So you can pair, for example, an LRA with SMD mounting if haptics and automated assembly are both priorities.

If none of the standard formats fit, Vybronics states it has applications engineers who can help select a motor or design one to meet specific requirements.

Vybronics provides two direct paths for motor selection and customization support: its Contact Us page and its About page, both reachable from the site's primary menu. The company states it has experienced applications engineers who can help you choose the right vibrating motor, or design a motor to meet your specific requirements. If your need is standard part selection, start with the product pages and then contact the sales engineering offices; if your need is a non-standard form factor, mounting style, or drive characteristic, go straight to the contact channel and describe the requirement.

What Vybronics says it offers

From the site's own description:

• In business since 1998, described as one of the largest manufacturers of LRA, SMD, and coin vibration motors.
• Production lines in Vietnam and China.
• Sales engineering offices in the USA and China.
• Motor technologies available: ERM (brush type), LRA (linear resonant actuators, coin and rectangular), BLDC brushless, plus SMD surface mount, through-hole PCB mountable, spring contact, and encapsulated/overmoldable variants.
• Stated support: applications engineers to help choose a motor, or to design a motor to specific requirements.

How to reach the right support

Step 1: Decide which question you actually have

Step 2: Use the site navigation

The primary menu on vybronics.com includes Home, All Products, New Products, Factory Tour, BLOG, About, Contact Us. The two entries relevant to support are About and Contact Us. The site also offers an EN / 中文 language toggle, which matters if your engineering team works in Chinese.

Step 3: Prepare the information before you write

The site does not publish a contact form field list, so the practical approach is to include the details an applications engineer would need to answer on the first pass:

• Application: cellphone, wearable, hearable, display panel, AR/VR hardware, drone, smart electronic lock, or other.
• Feedback type wanted: haptic feedback (LRA is described as best for this) versus simple vibration alert (ERM described as lowest cost).
• Drive constraints: LRA listings note low drive voltage and current but require a driver IC — state whether your design already includes one.
• Mounting and connection preference: SMD reflow solderable on tape and reel, through-hole PCB mountable, spring contact (solderless), or encapsulated/overmoldable for harsh environments.
• Physical limits: available space and target vibration force.
• Volume and timeline, since custom design work is a different conversation from catalog sampling.

Step 4: Expect one of two outcomes

• Selection support — the applications engineer recommends an existing motor from the ERM, LRA, or BLDC lines.
• Custom design — Vybronics designs a motor to your requirements, per its own statement on the site.

Common sticking points

• Assuming LRA drops into an ERM socket. The site explicitly notes LRA motors require a driver IC. If your board was designed around a brushed ERM driven directly, that is a hardware change, not a part swap.
• Contacting sales before defining the application. The site positions applications engineers as the selection resource; a vague inquiry tends to come back as a request for the same details listed above.
• Overlooking the mounting options early. Encapsulated/overmoldable, spring contact, through-hole, and SMD tape-and-reel parts differ in assembly process and field serviceability. Choosing the motor before the mounting method can force a redesign.
• Language and time zone. With sales engineering offices in the USA and China and production in Vietnam and China, matching your inquiry to the office closest to your team's working hours is worth doing.

Use an LRA (linear resonant actuator) when you need crisp, high-definition haptic feedback and can supply a dedicated driver IC. According to Vybronics, LRA motors are "best for haptic feedback" because they combine low drive voltage and current with high vibration force — but they require a driver IC to operate. If your design can't accommodate that driver, or you're optimizing purely for cost, an ERM motor is the better fit.

What Makes an LRA Different

An LRA drives a moving mass back and forth along a single axis at its resonant frequency, rather than spinning an offset weight like an ERM motor. That linear motion is what produces the sharp, controllable "click" feel associated with HD haptics.

Vybronics lists these characteristics for its LRA line:

• Best for haptic feedback
• Low drive voltage and current
• High vibration force
• Driver IC required

The driver IC point is the key constraint. An LRA won't run from a simple DC voltage the way an ERM motor does — it needs a driver that tracks and drives the resonant frequency.

When an LRA Is the Right Choice

Choose an LRA when most of these apply:

• Haptics are a core feature, not an afterthought — the tactile response needs to feel precise and repeatable.
• Power budget is tight. Low drive voltage and current matter in battery-powered devices.
• You need strong feedback in a thin package. High vibration force in a low-profile form factor suits space-constrained products.
• Your design already includes (or can include) a haptic driver IC.

Vybronics notes its tactile actuators are used for vibratory haptic feedback in cellphones, wearables, hearables, display panels, and augmented/virtual reality hardware using HD haptics — all cases where feedback quality justifies the driver requirement.

When an LRA Is the Wrong Choice

• Cost is the primary constraint. Vybronics describes its ERM brush-type coin motor as the "lowest cost of all vibration motors."
• You can't add a driver IC. Without one, the LRA won't function as intended.
• You only need basic alert vibration. A simple buzz doesn't require resonant linear motion.

Form Factors Available

Vybronics offers LRAs in more than one shape, so the choice isn't only "LRA vs. ERM" but also which LRA package fits your assembly:

Both are described with the same core advantages: best for haptic feedback, low drive voltage and current, high vibration force, and a required driver IC.

How to Decide

1. Confirm the feedback quality you need. If it's HD haptics, an LRA is the intended technology.
2. Check whether a driver IC fits your design. If not, rule the LRA out.
3. Compare against ERM if cost dominates — ERM is the lower-cost option.
4. Pick the shape (coin or rectangular) based on your mechanical envelope.
5. If the choice is still unclear, Vybronics states it has applications engineers who can help select the right motor or design one to specific requirements.

The short version: an LRA is the right call when haptic quality and power efficiency matter more than unit cost, and when a driver IC is part of the plan.

Vybronics builds vibration motors in three main technologies — ERM (eccentric rotating mass), LRA (linear resonant actuator), and BLDC (brushless DC) — and the right one depends on what your product needs to do. Choose ERM when cost matters most and you only need a general vibration alert. Choose LRA when you need crisp haptic feedback with low drive voltage and current. Consider BLDC when you want a brushless motor option outside the coin-motor mainstream. The rest of this article breaks down how each type works, what Vybronics says about it, and what to weigh before ordering.

The three technologies at a glance

Vybronics describes its ERM coin motor as the "lowest cost of all vibration motors," and its LRA products (coin and rectangular) as "best for haptic feedback" with low drive voltage and current and high vibration force — with the explicit note that a driver IC is required.

ERM: the low-cost default

ERM motors use a brushed DC motor with an unbalanced weight. When current flows, the weight spins and the whole assembly vibrates.

• Cost: Vybronics calls ERM the lowest-cost vibration motor technology.
• Drive: Straightforward — no special driver IC is called out for ERM the way it is for LRA.
• Form factors: Vybronics lists ERM brush-type coin motors, plus through-hole PCB-mountable and spring-contact variants.
• History: Vybronics notes that ERM-based vibrotactile feedback was pioneered by Namiki in 1984, when Motorola introduced the BPR-2000 pager with a 7 mm brush-type cylindrical ERM motor for its "Silent Alert." That feature was a costly option at the time; coreless micro-motor manufacturing later moved from Japan to China and Vietnam, and prices dropped dramatically.

Choose ERM if you need a basic vibration alert, want the lowest unit cost, and don't need fine-grained haptic control.

LRA: haptics with low drive voltage and current

A linear resonant actuator drives a mass back and forth along one axis at its resonant frequency, rather than spinning a weight. Vybronics lists two LRA shapes: coin LRA and rectangular LRA.

Vybronics' stated LRA advantages:

• Best for haptic feedback
• Low drive voltage and current
• High vibration force
• A driver IC is required

That last point is the practical dividing line. An LRA won't run from a simple DC on/off the way an ERM can — you need drive electronics that match the actuator's resonance. In exchange, you get the low-voltage, low-current, high-force behavior that makes LRA the standard choice for HD haptics.

Choose LRA if your product delivers haptic feedback (phones, wearables, hearables, display panels, AR/VR hardware) and your design already includes or can include a haptic driver IC.

BLDC: the brushless option

Vybronics lists BLDC brushless motors alongside ERM and LRA as one of the technologies its motors are available in. The company's coreless DC micro motors — a separate line from the tactile actuators — are used in applications from drones to smart electronic locks.

The source material doesn't detail BLDC drive requirements or pricing, so treat BLDC as an option to confirm directly with Vybronics rather than assuming it behaves like an ERM. If you need brushless operation for lifetime or electrical-noise reasons, ask Vybronics' applications engineers which BLDC frame fits your target.

How to decide

Work through these questions in order:

1. Do you need precise haptic feedback, or just an alert? Precise haptics → LRA. Simple alert → ERM.
2. Can your board supply a driver IC? LRA requires one. If your design can't accommodate it, ERM is the simpler path.
3. Is unit cost the deciding factor? ERM is the lowest-cost option per Vybronics.
4. Do you need a brushless motor? Look at BLDC, and confirm specs with Vybronics directly.
5. What mounting do you need? Vybronics offers SMD reflow solderable (on tape & reel), through-hole PCB mountable, spring contact, and encapsulated/overmoldable versions for harsh environments. Mounting style can narrow your technology choice before performance does.

Where Vybronics fits

Vybronics has been in business since 1998 and describes itself as one of the largest manufacturers of LRA, SMD, and coin vibration motors, with production lines in Vietnam and China and sales engineering offices in the USA and China. The company says its motors are known for being reliable, high quality, and competitively priced, and that its applications engineers can help you choose a motor or design one to your requirements.

If your choice comes down to a close call between ERM and LRA, that engineering support is the fastest way to resolve it — bring your drive voltage, current budget, target vibration force, and mounting constraints, and ask which technology meets all four.
