Audio Speaker and Headphone PCBA Assembly

Custom audio PCBA assembly for speakers, headphones, soundbars, Bluetooth earbuds and other consumer audio products. The solution supports SMT and through-hole assembly, with PCB design support for low-noise audio circuits and audio performance testing.

Custom Audio PCBA

The PCBA can be customized for different audio products, including wireless speakers, headphones, soundbars and smart speaker modules.

The assembly process supports audio codecs, Class D or Class AB amplifiers, DSP chips, Bluetooth modules and MEMS microphones according to the product design.

Low-Noise PCB Design

Audio products require careful PCB layout and grounding to reduce unwanted noise and interference.

The service provides low-noise layout and grounding design support, with component placement arranged according to the requirements of audio signal paths and power circuits.

Audio Amplifier PCBA

The PCBA can integrate audio amplifier circuits for speaker and headphone applications. Class D and Class AB amplifier designs can be supported according to the required output power and product architecture.

Bluetooth Audio Module Integration

Bluetooth SoCs and wireless audio modules can be integrated into the PCBA for wireless speakers, headphones and earbuds.

The design can also include DSP and related audio processing circuits for wireless consumer audio products.

ANC Headphone PCBA

The PCBA supports active noise cancellation headphone designs using ANC chips and MEMS microphones.

Bluetooth, DSP, ANC and microphone circuits can be integrated into a compact headphone control board according to the product requirements.

SMT and DIP Assembly

The manufacturing process supports SMT and DIP assembly, including fine-pitch components and optional BGA placement.

Audio-specific components such as codecs, amplifiers, DSPs, MEMS microphones and Bluetooth modules can be assembled according to the customer BOM.

EMI Shielding

EMI shielding can be added to audio PCB assemblies where protection from electromagnetic interference is required.

Shielding cans and RF shielding options can be considered for Bluetooth modules and other noise-sensitive circuits.

Audio Performance Testing

Audio PCBA testing can include total harmonic distortion, frequency response, signal-to-noise ratio and output power verification.

These tests help verify the assembled board against the electrical and audio performance requirements of the finished product.
