An electroacoustic component and its production process

Abstract

The invention discloses an electro-acoustic element and a production process thereof. The structure of the electro-acoustic element comprises an element housing, a sound transmission hole and a bottomcover are arranged on the shell of the element, At that middle of the upper surface of the element house, The bottom cover is embedded in the inside of the element shell, and the bottom cover is provided with a sealing ring, a pulling ring and a fixing column, the sealing ring is fixedly connected with the outer surface of the bottom cover, the pulling ring is fixedly connected with the middle ofthe bottom of the bottom cover, and the fixing column is fixedly connected with both ends of the upper surface of the bottom cover. The advantage of that invention are small volume. The sensitivity selection range and frequency response range are wide. By embedding the circuit board inside the connecting board, the use of bolts to fix the circuit board is effectively avoided, the installation time of the circuit board is saved, the production speed of the electro-acoustic components is accelerated, and the convenience of disassembly and assembly of the circuit board is improved, which has thecharacteristics of high signal-to-noise ratio, low distortion, good sound quality and low cost.

Description

technical field [0001] The invention relates to the technical field of electroacoustic components, in particular to an electroacoustic component and a production process thereof. Background technique [0002] Electro-acoustic devices refer to devices that convert electricity and sound. It uses electromagnetic induction, electrostatic induction or piezoelectric effects to complete electro-acoustic conversion, including speakers, headphones, microphones, cartridges, etc. [0003] At present, there are still some deficiencies in the existing electro-acoustic components, for example; the existing electro-acoustic components generally have relatively small sensitivity selection range and frequency response range, low signal-to-noise ratio, large distortion, poor sound quality and manufacturing The cost is relatively high. The existing electroacoustic components generally use bolts to fix the circuit board, which increases the installation time of the circuit board, slows down the...

Problems solved by technology

[0003] At present, there are still some deficiencies in the existing electro-acoustic components, for example; the existing electro-acoustic components generally have relatively small sensitivity selection range and frequency response range, low signal-to-noise ratio, large distortion, poor sound quality and manufacturing The cost is relatively high. The existing electroacoustic components generally use bolts to fix the circuit board, which increases the installation time of the circuit board, slows down the production speed of the electroacoustic component, and reduces the convenience of disassembling the circuit board. Existing electro-acoustic components are generally a sealed integral structure, which easily leads to the phenomenon that the internal parts cannot be repaired when the electro-acoustic component is damaged, which greatly reduces the convenience of disassembly and maintenance of the electro-acoustic component
