[0003] In existing portable audio systems, efficient energy utilization and thermal management have always been key factors restricting performance improvements and user experience. When operating, traditional audio systems generate a large amount of heat from the audio signal speakers. This heat is often dissipated inefficiently into the environment, resulting in energy waste. Excessive temperatures also affect the sound quality of the speakers, increase distortion, and potentially shorten the lifespan of the audio equipment.

A voice coil heat pipe 7 is provided on the top surface of the magnetic circuit 3. Circular holes are opened on the basin frame 5 and the fixed core support piece 6. The bottom surface of the voice coil heat pipe 7 passes through the circular holes of the basin frame 5 and the fixed core support piece 6 and contacts the top surface of the magnetic circuit 3. The voice coil heat pipe 7 transfers the heat generated by the voice coil winding 4. The energy-saving component also includes: a sound cone suspension 9, which is fixedly mounted on the sound cone suspension. A thermoelectric power generation sheet 8 is fixedly mounted on the top surface of the voice coil heat pipe 7 and the top surface of the cone suspension 9.

The heat on the voice coil winding 4 is transferred to the thermoelectric power generation sheet 8 through the voice coil heat pipe 7.

[0025] Working principle:

[0026] When in use, when the audio signal speaker 1 is working, the voice coil winding 4 generates heat due to the passage of current. This heat is quickly transferred to the thermoelectric power generation sheet 8 on the sound cone suspension 9 through the voice coil heat pipe 7. The voice coil heat pipe 7 is made of high-efficiency thermal conductive material to ensure that heat can be transferred quickly and effectively. The thermoelectric power generation sheet 8 is a thermoelectric conversion device based on the Seebeck effect, which can convert thermal energy into electrical energy. In the present utility model, the bottom surface of the thermoelectric power generation sheet 8 is in close contact with the voice coil heat pipe 7, receiving heat from the voice coil winding 4, and its top surface is in contact with the outside air, forming a temperature difference. This temperature difference The thermoelectric power generation sheet 8 is enabled to generate electrical energy, and the generated electrical energy is processed by a circuit recovery system, including voltage stabilization, filtering and other steps, and then stored in a lithium battery 10. The lithium battery 10 provides electrical energy for the audio equipment, and the recovered electrical energy can replenish the power of the lithium battery 10, thereby extending the playback time of the audio and reducing the number of charging times. Through the above-mentioned thermal management system, not only is energy recycling achieved, but the temperature inside the speaker is also reduced. The reduction in temperature helps to improve the distortion of the speaker and improve the sound quality.
