Abstract

The invention discloses a sounding device. The sounding device comprises a diaphragm sounding device and a piezoelectric sounding device, wherein the diaphragm sounding device comprises vibrating diaphragms, the piezoelectric sounding device comprises piezoelectric plates, the vibrating diaphragms are arranged opposite to the piezoelectric plates, and the vibrating diaphragms are spaced from the piezoelectric plates. The sounding device disclosed by the invention has the characteristics of good low frequency and high frequency effects.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a sound generating device. Background technique [0002] In the prior art, in order to achieve an ideal low-frequency effect, a dynamic sounding unit is usually used. In order to achieve the ideal high-frequency effect, a moving iron sounding unit or a piezoelectric sounding unit is usually used. In some examples, such as earphones, a separate moving coil sounding unit and a moving iron sounding unit or a moving coil sounding unit and a piezoelectric generating unit are used to achieve both low frequency and high frequency sound effects. [0003] However, placing multiple units in the earphone case has relatively strict requirements on the design of the earphone structure. The volume of the earphone is usually large, and there are also relatively strict requirements on the assembly process. Contents of the invention [0004] An object of th...
