Detailed ways

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

1 to 3, a Bluetooth speaker of the present invention includes a speaker body 4, a speaker 3, a battery 7 and a control member 8. The speaker body 4 has a cylindrical shape, and the control member 8 is connected to the speaker 3. The battery 7 supplies power to the control unit 8. The speaker body 4 is internally provided with a cavity, and the lower portion of the speaker body 4 is connected with a bottom cover 10 which is closed at the bottom of the cavity. The battery 7, the control unit 8 and the speaker 3 are arranged. In the cavity, the control member 8 is fixed by a screw, and the control member 8 includes a charging circuit 14, a Bluetooth module 13, a power amplifier circuit 15, a control circuit 16, and a button 17, and the control circuit 16 is provided with a TWS box circuit. The charging circuit 14 is connected to the battery 7. The control circuit 16 is connected to the power amplifier circuit 15, the Bluetooth module 13, the charging circuit 14, and the button 17, respectively. The power amplifier circuit 15 is connected to the driving speaker 3.

Specifically, the battery 7 supplies a voltage of 3.7V to the control unit 8; the battery 7 is charged by the charging circuit 14; the switching operation and the matching operation of the box are transmitted to the control circuit 16 through the button 17, and the control circuit 16 forms an information exchange with the Bluetooth module 13 to form Related operations; the Bluetooth module 13 is responsible for communicating with the mobile phone, and can convert the Bluetooth signal into a digital signal to the control circuit 16, the control circuit 16 drives the audio signal through the power amplifier circuit 15 to drive the speaker 3 to play music; and the control unit 8 uses the central processing unit of Jieli , 8-bit kernel, decoding and processing Bluetooth data, button 17 uses long-press mode for any speaker pairing, Bluetooth module 13 performs Bluetooth BLE 4.2 and Bluetooth 2.1 + EDR dual mode standard, stable communication, long distance, excellent performance.

The invention provides a TWS pair box circuit in the control circuit 16, so that two smart speakers can be used to simultaneously connect two bluetooth speakers to realize sound synchronization, and the volume is larger, and the wireless stereo effect is achieved, thereby providing better sound effects for the user.
