Description
Technical Field
The utility model relates to the field of microphones, in particular to a voice recognition microphone assembly.
Background
The microphone is an energy conversion device for converting sound signals into electric signals, is a device which is opposite to a loudspeaker, can be structurally divided into a grid spot welding type, a grid press-connection type, a pole ring connection type and the like, is two terminals of sound equipment, and is input, and the loudspeaker is output.
In speech recognition technique, have higher requirement to the radio reception effect of microphone, the miaow head that sets up on the circuit board is put for a long time and can lead to the acoustic control insensitive because seal dirt, and influence user's impression when normal use, consequently, seal the processing very key to the miaow head, current miaow headgear that is used for parcel miaow head is used for playing dustproof effect, but mainly installs through the gum mode, because miaow head volume is less, the gum mode paste the operation very inconvenient, and paste the firm degree gradually reduced with time, in view of this, the field researchers have designed a speech recognition miaow head subassembly.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a voice recognition microphone assembly with stable installation.
The technical scheme of the utility model is as follows: the utility model provides a voice recognition miaow head subassembly, is in including miaow head and the cover that sets up on the circuit board are in miaow head cover on the miaow head cover is provided with and holds the chamber that holds of miaow head, miaow head cover bottom is the diagonal angle and is provided with two erection columns, be provided with on the miaow head cover with the radio reception hole on the miaow corresponds the afferent sound hole that sets up, be provided with on the circuit board with erection column interference fit's locating hole.
According to the scheme, the microphone sleeve is used for protecting the microphone and playing a dustproof role, the sound receiving hole is used for inputting sound signals, the microphone is sleeved in the accommodating cavity, the sound receiving hole corresponds to the sound receiving hole, the sound is conducted conveniently, the sound is conducted when the microphone is dustproof, the microphone sleeve is fixedly connected to the circuit board through the interference fit between the positioning hole and the mounting column, the mounting column which is arranged diagonally is used for the microphone sleeve to be mounted more stably, and the mounting column is arranged in the waist-shaped positioning hole to leave a movable space.
The microphone cover comprises a connecting convex part and a cover part integrally arranged with the connecting convex part, the accommodating cavity is positioned in the cover part, and the two mounting columns are arranged on the connecting convex part. Therefore, the cover part is used for being sleeved on the microphone, and the connecting convex part is used for enabling the end part to be in contact with the circuit board so as to realize fixed installation between the circuit board and the circuit board.
The mounting column comprises a cylindrical portion and a round platform portion arranged at the bottom of the cylindrical portion. Therefore, the round platform part is convenient to penetrate through the positioning hole to achieve interference fit, and accordingly fixation of the microphone sleeve on the circuit board is achieved.
And a chamfer is arranged at the inner connection part of the connecting convex part and the cover part. Therefore, the chamfer enables the microphone and the microphone sleeve to have gaps and a certain heat dissipation effect.
The positioning holes are arranged in a waist-shaped hole. Therefore, an adjusting space is formed between the circuit board and the microphone sleeve through the waist-shaped through hole.
The diameter of the sound transmission hole is larger than that of the sound receiving hole. Therefore, the sound transmission hole is used for realizing sound reception while sealing the microphone, and the sound transmission hole with large diameter is convenient for more complete sound input.
