Detailed Description
The utility model provides a novel but high-quality response audio amplifier that wireless charges, include the audio amplifier shell body of compriseing plastic shell 1 and plastic drain pan 16, the audio amplifier shell body in install main circuit board 10, built-in rechargeable battery 3, public address sensing element 14, left loudspeaker 2 and right loudspeaker 5 of mutual electricity connection, left loudspeaker 2 and right loudspeaker 5 expose by the both ends of controlling of audio amplifier shell body respectively, main circuit board 10 electricity is connected with shift knob 6, audio input socket 7 and built-in rechargeable battery interface 9 that charges, shift knob 6, audio input socket 7 and built-in rechargeable battery interface 9 that charges expose the outside of audio amplifier shell body, main circuit board 10 electricity is connected with the wireless power supply interface 11 that charges of mutual electricity connection, wireless charging circuit board 12, wireless charging coil 13 and sensing circuit board 15, install resonant membrane 4 in the audio amplifier shell body.
The specific implementation mode is as follows:
1. the switch button 6 is pressed to start the sound box of the utility model;
2. a sound production loudspeaker arranged in the mobile phone is close to the sound amplification sensing element 14;
3. the left loudspeaker 2 and the right loudspeaker 5 can send music of the mobile phone or other audio being played;
4. volume of left loudspeaker 2 and right loudspeaker 5 of controllable audio amplifier of adjustment cell-phone volume size
5. The external power supply is connected to the wireless charging power supply access port 11;
6. when the wireless charging induction position is close to the wireless charging induction indication position (which is the middle position of the main panel 1-1 of the plastic shell 1), the mobile phone can be charged at the same time.
7. When the indicator light 17 shows red, it indicates that the built-in rechargeable battery 3 of the sound box needs to be charged. And (4) connecting an external power supply to the charging interface 9 of the built-in rechargeable battery until the indicator lamp 17 displays blue, which indicates that the charging is finished.
