The invention discloses an electro-acoustic conversion apparatus which comprises a body, a first net and a second net. The first net and the second net are used for clamping the body between the first net and the second net. According to the electro-acoustic conversion apparatus disclosed by the invention, by additionally arranging a rigid frame between the second net and the body, structural intensity is improved, and a distance between a stationary electricity thin film of the body and an electrode plate is stabilized, so that a sound pressure is stabilized, and a good sound effect is provided; and moreover, the rigid frame is provided with at least one first opening, and the at least one first opening corresponds to at least one sound production unit of the body, so that sound produced by the at least one sound production unit passes through the corresponding first opening to be propagated, and arrangement of the rigid frame cannot influence sound propagation.
Description
technical field [0001] The invention describes an electroacoustic conversion device, especially an electrostatic electroacoustic conversion device. Background technique [0002] Traditional speakers are mainly divided into dynamic speakers, piezoelectric speakers and electrostatic speakers according to their driving methods. Dynamic speakers mainly use the interaction of magnetic field, current and force at right angles to control the piston-type repetitive movement of the diaphragm. Because the volume cannot be reduced, it cannot meet the needs of future products for thinner and lighter products. Piezoelectric speakers use the piezoelectric effect. When an electric field is applied to the piezoelectric material, the piezoelectric material will be deformed, and then the diaphragm will be pushed to produce sound. However, the resonance frequency required by the piezoelectric material is high and the bandwidth used is insufficient. Therefore, the applicable fields are limited...
