Abstract

The invention relates to a middle-tone sounding board with a matrix arrangement of pronunciation air ducts, which relates to a middle-tone sounding board, in particular to a middle-tone sounding board with a matrix arrangement of pronunciation air ducts. The present invention solves the problem that the mid-range sounding board used in the existing flat-panel audio system generally adopts a honeycomb arrangement, and the connection area between two adjacent sounding air ducts is relatively large, which affects the sound quality and tone color of the sound. The present invention comprises two skins and a plurality of pronunciation ducts, the plurality of pronunciation ducts are arranged in a matrix between the two skins, and two adjacent rows of pronunciation ducts are interlaced, and the length of each pronunciation duct is 3mm- 6mm, the inner diameter of each pronunciation duct is 5mm to 10mm, and the wall thickness of each pronunciation duct is 0.07mm to 0.1mm. The invention belongs to the field of multimedia equipment.

Description

technical field [0001] The invention relates to a middle-tone sounding board, in particular to a middle-tone sounding board with sounding ducts arranged in a matrix, which belongs to the field of multimedia equipment. Background technique [0002] The flat-panel audio is composed of a sound source input device, a signal amplifier and a speaker. It is a complete system that excites the bending wave in the sounding board through the exciter to produce sound. After several years of market expansion in the industry, it has been widely used in: home theater system, background music system, multimedia audio system, public address system, etc. The mid-range sounding board used in the existing flat-panel audio system is generally arranged in a honeycomb shape, and the connection area between two adjacent sounding air ducts is relatively large, which affects the sound quality and timbre of the sound. Contents of the invention [0003] The present invention solves the problem that ...
