Abstract

The utility model belongs to the radio communication equipment field, throat mark formula air conduction electrophone promptly. The voice frequency plug comprises a PTT switch and a transmitter-receiver part, and is characterized in that two throat marks connected with an audio plug are connected in parallel; the PTT switch and the handset are connected by adopting a connection method of an audio plug and an audio socket. Through the parallelly connected design of 2 throat marks, make the collection that the transmitter talks the speech signal more sensitive, reduce the distortion, overcome 1 throat mark and cause the distortion easily, the conversation is intermittent, unclear problem. Aiming at the maintenance condition of the transmitter and receiver, in order to facilitate the maintenance of maintenance personnel, the PTT and the transmitter and receiver are designed in a segmented mode and connected through the audio plug, so that the fault removal of the maintenance personnel in a segmented mode is facilitated, and the maintenance efficiency is improved. And, adopt PTT and electrophone to design by stage, when the irreparable trouble appears, only need to change the damaged part can, do not need to change the complete equipment, this not only can reduce user's economic cost, and the most important thing still saves energy and protects the environment.

Description

Throat mark type air conduction electrophone

Technical Field

The utility model belongs to the radio communication equipment field, throat mark formula air conduction electrophone promptly.

Background

In prior art, people's generally used throat mark formula air conduction electrophone on the market is a throat mark usually, and collection sensitivity to speech signal is not high enough, produce the distortion easily, leads to listening to the final sound that hears intermittent and continuous, the not good problem of speech quality of end. The integration of the PTT switch with the handset is not conducive to maintenance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid not enough and provide a throat mark formula air conduction electrophone, overcome former speech quality not good, intermittent and continuous, the unchangeable problem of maintenance.

The technical solution of the utility model is that: the throat mark type air conduction transmitter-receiver comprises a PTT switch and a transmitter-receiver part, and is characterized in that the throat marks connected with the audio plug are connected in parallel by adopting two throat marks; the PTT switch and the handset are connected by adopting a connection method of an audio plug and an audio socket.

Because the vocal cords of the person are one on the left and the right, two throat marks are used and exactly correspond to the left vocal cords and the right vocal cords one on the side.

Because throat mark formula air conduction receives the ware, mainly supply outdoor user and the user in the motion to use. In the motion process, throat mark can be with body motion amplitude size, take place the position and remove, skew vocal cord and the not tight condition of vocal cord subsides, lead to throat mark to change or can not produce the electric current along with the intensity of the induced-current of vocal cord vibration production, the sound signal that the other side was heard will be intermittent and intermittent this moment, and adopt two parallelly connected methods of throat mark, can overcome this problem because can play the balanced action about two throat marks, when one of them removes simultaneously, when producing the neutral gear, can play the benefit difference effect, thereby keep jointly unblocked.

Because each width of the vocal cords of the person is about 2-3 cm, the area of the size of one throat mark is just accommodated. Adopt the throat mark more than 3, surpass the throat mark of vocal cord part and do not have any meaning, increase the burden of neck on the contrary, be unfavorable for wearing for a long time, so use 2 throat marks to connect in parallel, each 1 about, for best configuration.

The utility model has the advantages that: 1. through the parallelly connected design of 2 throat marks, make the collection that the transmitter talks the speech signal more sensitive, reduce the distortion, overcome 1 throat mark and cause the distortion easily, the conversation is intermittent, unclear problem. Simultaneously 2 throat marks are parallelly connected, and 1 can also continue to use when wherein 1 damages in addition. 2. Aiming at the maintenance condition of the transmitter and receiver, in order to facilitate the maintenance of maintenance personnel, the PTT and the transmitter and receiver are designed in a segmented mode and connected through the audio plug, so that the fault removal of the maintenance personnel in a segmented mode is facilitated, and the maintenance efficiency is improved. And, adopt PTT and electrophone to design by stage, when the irreparable trouble appears, only need to change the damaged part can, do not need to change the complete equipment, this not only can reduce user's economic cost, and the most important thing still saves energy and protects the environment.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
