Abstract

The invention discloses non-equal acoustic resistance screen cloth and a sound production device. The non-equal-acoustic-resistance screen cloth is applied to the sound production device, the sound production device is provided with airflow holes, the non-equal-acoustic-resistance screen cloth is used for covering the airflow holes, the non-equal-acoustic-resistance screen cloth comprises at least two damping areas, and the damping areas are provided with meshes with different hole diameters. According to the technical scheme, the function of adjusting the airflow velocity is achieved, and different acoustic requirements are met.

Description

Technical field [0001] The present invention relates to the field of electroacoustic conversion techniques, and more particularly to a non-equal acoustic resist mesh and a sound device. Background technique [0002] The vocal device is a basic unit for electroacoustic conversion and is widely used in consumer electronic devices. There is a air flow hole (e.g., a leak hole on the sound monomer, or a sound hole on the housing in the case in the sound device, or the pressure barrier hole on the housing in the sound device, or a gas permeable spacer in the sound device. The gas intake hole). At present, various electronic devices (mobile phones, sound, etc.) are in order to pursue a better sound quality, usually use such an acoustic resistance mesh cloth to cover the airflow hole to achieve filtering effect. As such, when the sound wave enters the airflow hole, it will pass through an acoustic resistance mesh; however, since the acoustic resistance mesh cannot adjust the airflow flow...
