Description

Explosion-proof type shoulder miaow

Technical Field

The utility model relates to a shoulder miaow field, in particular to explosion-proof type shoulder miaow.

Background

The shoulder microphone is also called as a hand microphone, and after the shoulder microphone is connected with the interphone, the interphone can be used for talkback by hanging the shoulder microphone on the shoulder without holding the interphone by hand, so that the shoulder microphone is convenient for rescue or operation personnel to use. At present, interphone is widely used as a communication means in the field of emergency rescue and mining industry, not a mobile phone, wherein the shoulder microphone is the most common one.

Conventional hand miaow function singleness only has microphone and loudspeaker, and the power is lower during the use, hardly listens to sound clearly in noisy environment, need wear the earphone, wears the earphone under some environment and can bring inconvenience for the user. In addition, the conventional hand microphone has no volume increasing and decreasing keys, and the user needs to adjust the sound on the interphone, so that the convenience is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides an explosion-proof type shoulder miaow to solve at least one above-mentioned technical problem.

In order to solve the above problem, as an aspect of the present invention, there is provided an explosion-proof shoulder microphone, including: the microphone, the loudspeaker and the circuit board are arranged in the shell, the first PTT key is arranged on the front face of the shell, the second PTT key is arranged on the left side face of the shell, the SOS key is arranged on the top face of the shell, the volume increasing key and the volume reducing key are arranged on the right side face of the shell, and the circuit board is electrically connected with the microphone, the loudspeaker, the circuit board, the first PTT key, the second PTT key, the SOS key, the volume increasing key and the volume reducing key respectively.

Preferably, a power amplification circuit matched with the horn is arranged on the circuit board.

Preferably, the housing is made of fire-resistant PC.

Preferably, the back of the housing is provided with a back clip capable of rotating 360 degrees.

Preferably, an external microphone plugging female seat electrically connected with the circuit board is arranged on the shell.

Preferably, a horn button is disposed on the left side surface of the housing.

Since the technical scheme is used, the utility model discloses a sound adjustment button at the side setting, convenience of customers carries out volume control, has improved user experience.
