Abstract

The embodiment of the invention discloses a novel piezoelectric loudspeaker, which is applied to the technical field of electroacoustics, and comprises a first piezoelectric plate, a second piezoelectric plate, a bass diaphragm and an acoustic cavity, wherein the first piezoelectric plate and the second piezoelectric plate are respectively adhered to two sides of the bass diaphragm to form a piezoelectric plate bass diaphragm structure, and the first piezoelectric plate and the second piezoelectric plate are connected in parallel; the piezoelectric plate bass diaphragm structure is pasted at the opening of the vocal cavity, so that the bass function of the piezoelectric loudspeaker is more obvious, and the sound volume of the piezoelectric loudspeaker can be improved.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a novel piezoelectric speaker. Background technique [0002] Loudspeakers are widely used in various audio and communication equipment. Piezoelectric speakers (hereinafter referred to as piezoelectric speakers) have the advantages of low energy consumption and light weight, but piezoelectric speakers have two fatal flaws: one is that they cannot be used for low-frequency playback, and are limited to high-frequency applications; the other is the sound pressure level Relatively low, that is, the sound is relatively small. The existing technology has not made breakthroughs in the low-frequency sound of piezoelectric speakers for many years. Piezoelectric speakers are limited to the sound of certain high-frequency prompts and warning sounds, which greatly limits the applicable scenarios. Contents of the invention [0003] The invention provides a novel piezoelectric speaker, ...
