Abstract

The embodiment of the invention provides a loudspeaker and terminal equipment, relates to the technical field of communication, and aims at solving the problem that the tone quality output by the loudspeaker in the existing terminal equipment is poor. The loudspeaker comprises a non-closed cavity, a vibrating diaphragm part arranged in the cavity and a piezoelectric part arranged on the first surface of the vibrating diaphragm part, the second surface of the vibrating diaphragm part and the first inner surface of the cavity are arranged at intervals, and the first surface of the piezoelectricpart and the second inner surface of the cavity are arranged at intervals; wherein the first surface and the second surface of the vibrating diaphragm component are two opposite surfaces on the vibrating diaphragm component, the first surface and the second surface of the piezoelectric component are two opposite surfaces on the piezoelectric component, and the second surface of the piezoelectric component is in contact with the first surface of the vibrating diaphragm component. The loudspeaker can be applied to the terminal equipment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a loudspeaker and a terminal device. Background technique [0002] As an electro-acoustic transducer, the speaker usually includes piezoelectric speakers, electromagnetic speakers, capacitive speakers, dynamic speakers, etc. [0003] At present, the working principle of the piezoelectric speaker is usually: the piezoelectric ceramic sheet is pasted on the middle frame or the screen of the terminal device, and the piezoelectric ceramic sheet vibrates to drive the middle frame or the screen to vibrate to emit sound. [0004] However, since the above-mentioned piezoelectric speaker vibrates the middle frame or the screen to produce sound through the vibration of the piezoelectric ceramic sheet, the electro-acoustic conversion effect of the speaker is not high, resulting in poor sound quality output by the speaker. Contents of the invention ...
