Problems solved by technology

There are two problems with this open MIC pickup hole structure. One is that holes need to be opened on the device casing. Too small holes affect the sound reception effect, and too large holes affect the appearance. Dust or dirt can easily accumulate in the MIC sound pickup hole and block the sound pickup hole, causing the MIC to fail to receive sound.

Abstract

The invention discloses a pickup hole structure for a microphone (MIC). The pickup hole structure consists of a switch button, a button flange and an equipment shell, which are matched. The switch button and the button flange are oppositely fixed to form a switch component which is assembled in a button hole in the equipment shell. An MIC electronic component is welded to a printed circuit board (PCB) of equipment to form a PCB component which is assembled in the equipment shell. When a switch block is turned on, a sound leading channel is formed at the button flange; and when the switch block is turned off, the upper surface of the button flange and the inner surface of the equipment shell form a closed surface. The pickup hole of the MIC is hidden at the flange of the switch button, so that the appearance of the equipment can be effectively improved, and a good dustproof effect can be achieved; and the pickup hole structure is applied to communication equipment with a sound recording or reception function, such as a portable Bluetooth sound box.

Description

technical field [0001] The invention relates to a MIC sound pickup hole structure. Background technique [0002] Communication equipment and equipment with recording and radio functions need to be installed with a MIC for radio reception. Most of the existing equipment uses a built-in MIC. In order to achieve the purpose of sound collection, the built-in MIC needs a sound pickup hole structure to introduce external sound into the internal MIC electronic components. [0003] At present, most of the pickup hole structures with built-in MIC are open, that is, a hole is opened on the device casing, and the inside of the hole is directly connected to the MIC electronic parts. network. There are two problems with this open MIC pickup hole structure. One is that holes need to be opened on the device casing. Too small holes affect the sound reception effect, and too large holes affect the appearance. In the process, dust or dirt can easily accumulate in the MIC sound pickup hole ...
