The PCBA (Printed Circuit Board) solution for GLE speakers mainly involves core modules such as Bluetooth function, wireless charging, and multi input support. The specific information is as follows:

I.  Core functional modules

i. Bluetooth function

• Supports Bluetooth V5.1+BR+EDR+BLE specifications, compatible with SBC and AAC audio decoding, and can handle formats such as MP3 and WAV.

• Integrated microphone input, echo cancellation (AEC), noise suppression (ENC), and equalizer to enhance the sound quality experience.

ii. Wireless charging and multi input

• Equipped with a 10W wireless charging control module to meet the charging needs of mobile phones.

• Supports dual input of U-shaped wireless microphone, 3.5mm wired microphone, as well as Line in input and Bluetooth accompaniment dual input.

iii. Power supply and battery life

• Equipped with a 3.7V power supply voltage and a built-in 5000mAh battery, it supports live streaming from two phones simultaneously.

• Equipped with 16 ohm/32 ohm speaker loads to meet different sound effects requirements.

II. PCBA design features

High integration: The main control chip adopts AC6965E (32-bit DSP processor), supporting high sampling rates (8KHz-24KHz) and multi-channel audio processing.

Strong scalability: Supports RGB rainbow light bar function, suitable for smart speakers, alarms and other scenarios.

III. Application scenarios

i. Smart Home: Integrated alarm clock, lighting control and other modules to achieve multifunctional integration.

ii. Mobile devices: support wireless charging of mobile phones, multi input switching, and large capacity battery life.
