Sound-generating devices and wearables

Abstract

The invention discloses a sounding device and a wearable device. The sounding device includes a casing, a vibration system, an auxiliary system and a magnetic circuit system accommodated in the casing; the vibration system includes a vibrating membrane and a driving assembly connected with the vibrating membrane, and the driving assembly It includes a flat voice coil; the auxiliary system includes a first damper, and the two ends of the first damper are respectively fixed to the housing and the drive assembly; the magnetic circuit system includes a magnet assembly and a guide set on the magnet assembly. The magnetic assembly, the magnetic assembly includes an upper magnet unit and a lower magnet unit, the magnetic conduction assembly includes a first magnetic conduction plate and a second magnetic conduction plate respectively arranged correspondingly to the long axis of the voice coil, and the first magnetic conduction plate is located between the upper magnet unit and the lower magnet unit. Between the lower magnet units, the second magnetically conductive plate is located at the end of the upper magnet unit away from the first magnetically conductive plate; it can not only ensure the lightness and beauty of the glasses legs, but also make full use of the inner space of the glasses legs, and prevent the voice coil from vibrating Polarization occurs in .

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device and a wearable device. Background technique [0002] With the rapid development of the consumer electronics industry, there is also a strong demand for various smart wearable terminals, such as smart glasses, which not only have the functions of traditional glasses, but also have many entertainment functions. For example, smart glasses can have a built-in Bluetooth system to realize the function of a Bluetooth headset, and can be connected to a mobile phone for use, and the smart glasses can be used to answer calls or play music stored in the mobile phone. In modern speaker technology, the acoustic performance of a dynamic speaker is directly related to its size. The larger the size, the better the acoustic effect, and the smaller the size, the worse the acoustic effect. Due to the consideration of portability, comfort and aesthetics,...
