What Components Do You Need to Assemble a Wireless Lavalier Microphone?
To build a basic 1-to-2 wireless lavalier microphone set, you’ll need the following:
| Component | Description |
|---|---|
| 🔘 Mainboard + Wireless Chipset | Controls audio processing and wireless transmission. Choose a solution like Jerry or Bluetrum. |
| 🎤 Microphone capsule (MEMS) | Small electric condenser mic capsule that captures the voice. |
| 🔋 Battery | Lithium polymer battery (30–60mAh for TX; 90–120mAh for RX). |
| 📶 Antenna (FPC or PCB) | For 2.4GHz signal transmission. Often embedded on the mainboard. |
| ⚡ Charging port | Type-C or Lightning connector (for the receiver). |
| 📦 Plastic housing | Injection-molded shell for each mic and receiver. |
| 📎 Metal clip + windscreen | Clip for attaching to clothing; foam or furry windscreen to reduce noise. |
| 🧃 Charging case (optional) | Portable storage box with built-in battery and USB charging. |
A full set typically includes 2 transmitters, 1 receiver, and optionally 1 charging case.
How Much Does It Cost to Build One?
Based on current Chinese supply chain prices, here’s a breakdown of estimated BOM (bill of materials) cost:
✅ Without Charging Case (Just the 3 devices)
| Tier | Target Use | Estimated Cost (RMB) | Approx. USD |
|---|---|---|---|
| 🔹 Low-end (e.g. Jerry AC692 or Bluetrum ATS2815) | Entry-level creators, TikTok beginners | ¥45–55 | $6–8 |
| 🔸 Mid-range (e.g. Jerry AC6969 or Bluetrum ATS3015) | YouTubers, teachers, online sellers | ¥70–85 | $10–12 |
| 🔶 High-end (e.g. Jerry AC701 or Bluetrum ATS2833) | Brands, influencers, studios | ¥110–130 | $15–18 |
✅ With Charging Case (Adds battery + mold + USB module)
| Tier | Additional Case Cost | Total Est. Cost (RMB) | USD |
|---|---|---|---|
| Low-end | ¥8–12 | ¥55–65 | $7.5–9 |
| Mid-range | ¥10–15 | ¥80–100 | $11–14 |
| High-end | ¥15–20 | ¥125–150 | $17–21 |
Where to Buy These Parts in China
You can source components from Chinese platforms or factories:
Alibaba / 1688 / Made in China: Good for small quantities and sample orders
Shenzhen or Dongguan suppliers: Specialize in OEM/ODM microphone production
Trade fairs (e.g. Canton Fair): Ideal for finding reliable long-term suppliers
Look for:
1. Factories offering Jerry or Bluetrum solutions
2. Clear product photos and specs
3. Willingness to send small samples for testing
🧠 Pro tip: If you don’t want to deal with mold design or PCB programming, ask for semi-finished kits — you can still brand and package them locally.
Is It Worth It to Assemble Mics Yourself?
Let’s weigh the pros and cons.
✅ Pros:
1. Lower cost per unit than buying fully-assembled retail products
2. More control over customization, packaging, and branding
3. Build your own product line without full-scale manufacturing
4. No MOQ on some components — test before scaling
Cons:
1. Higher learning curve — need knowledge of hardware and soldering
2. Logistics — shipping multiple parts can be time-consuming
3. No after-sales support — you’re responsible if something fails
4. Import taxes / regulations vary by country
Our Honest Suggestion
