Wearable devices, Audio technology, Loudspeaker technologyAbstract
This paper primarily focuses on the audio technology utilized in wearable devices. It conducts a comprehensive and detailed review of the evolutionary trajectory of audio technology, which not only encompasses the application of speakers but also the various challenges encountered in the design process. Additionally, it delves deep into the theoretical underpinnings of micro speaker physics, integration, and low power audio technology. Furthermore, meticulous tests and evaluations are carried out on both wearable device speakers and bone conduction speakers. The outcomes clearly reveal certain limitations present in the current speakers. Consequently, the conclusion drawn is that future wearable device speakers urgently necessitate technological innovation to significantly enhance sound quality, optimize power consumption, improve durability, and elevate the overall user experience. Future research directions encompass the exploration of advanced audio processing algorithms and low-power strategies, as well as the undertaking of extensive and in-depth user research to gain deeper and more valuable insights.References
