Problems solved by technology

However, the increase in the vibration area will lead to an increase in product size, which will affect the application of the whole machine
Moreover, the further increase of the working amplitude will bring various quality problems
[0004] On the other hand, with the development of acoustic technology, some high-demand acoustic effects can no longer be achieved through existing sound-generating devices

Description

technical field [0001] The invention belongs to the technical field of electro-acoustic transduction, in particular, the invention relates to a double-sided miniature sound generating device. Background technique [0002] In recent years, consumer electronics products have developed rapidly, and electronic products such as smart phones, tablet computers, and VR devices have been widely recognized by consumers and widely used. The sound generating device is an important electro-acoustic transducer component in consumer electronic products, and it is widely used as speakers, earpieces, earphones, etc. Along with the improvement of the performance of electronic products, the improvement of the acoustic performance of related sound generating devices is also an inevitable trend. [0003] In existing sound generating devices, the performance is generally improved by increasing the vibration area and working amplitude of the sound generating device. However, the increase in the ...
