Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a communication device with a noise reduction device, which solves the problem that the external sound will interfere with the conversation, causing the two parties using the walkie-talkie to be unable to hear clearly, resulting in the phenomenon that the quality of the conversation is poor , and when using it, the user often needs to hold the walkie-talkie with his hands, which will cause the user's hands to be tired or numb for a long time, so that the walkie-talkie will fall, causing damage to the walkie-talkie, and when the outside weather suddenly changes and it rains, Will cause water damage to communication equipment

Embodiment 1

[0041] see Figure 1-6 , a communication device with a noise reduction device, including a protective case 3, an intercom 10 is provided inside the protective case 3, and a universal microphone 5 is provided on the front of the intercom 10, and the microphone refers to a microphone used in a communication system , generally divided into two types: general-purpose microphone 5 and anti-noise microphone. The general-purpose microphone 5 is used in general environments and is divided into two types: active and passive. Occasionally used, according to different working principles, it can be divided into two types: air conduction type and contact type. It can convert sound into voice current, so it is an acoustic-electric conversion device. Microphones are generally divided into two types, namely linear microphones and Non-linear microphones, people call the microphones whose sensitivity does not change with the sound pressure as linear microphones, and vice versa, they are called ...

Embodiment 2

[0045] see Figure 1-6 On the basis of Embodiment 1, a further improvement has been made: the outer surface of the antenna of the walkie-talkie 10 is covered with a seal ring 1, the bottom surface of the seal ring 1 is fixedly connected with the upper surface of the protective case 3, and the antenna of the walkie-talkie 10 is tightly connected to the seal ring 1. Cooperate, the left side of rubber cover 18 is provided with equidistantly arranged anti-slip strips 19, the right side of each anti-slip strip 19 is fixedly connected with the left side of rubber cover 18, and the inner wall of rubber cover 18 is fixedly connected with two rubber Balls 22, the right side of each rubber ball 22 is fixedly connected with the left side of the protective shell 3.

[0046] In this embodiment, the antenna of the walkie-talkie 10 is sealed with the through hole 2 through the sealing ring 1 to increase the waterproof effect, and the anti-slip strip 19 can be used to prevent the user from sl...

Embodiment 3

[0048] see Figure 1-6 On the basis of Embodiment 1, a further improvement is made: the upper surface of the base plate 7 is fixedly connected with a silica gel pad 30, the upper surface of the silica gel pad 30 is in contact with the bottom surface of the walkie-talkie 10, and the outer surface of the walkie-talkie 10 is covered with a limit plate 4 , the bottom surface of the limiting plate 4 is fixedly connected with the upper surface of the base plate 7, the bottom of the base plate 7 is provided with a rubber pull ring 8, the upper surface of the rubber pull ring 8 is fixedly connected with the bottom surface of the base plate 7, and the front of the limiting plate 4 is provided with The sound transmission hole 29, the sound transmission hole 29 is located between the microphone tube 28 and the universal microphone 5, the inner wall of the protective case 3 is fixedly connected with a sponge pad 13, and the front of the sponge pad 13 is in contact with the back side of the...

Abstract

The invention belongs to the technical field of communication equipment, and in particular, relates to communication equipment with a noise reduction device. The communication equipment comprises a protective shell; an interphone is arranged in the protective shell; the front surface of the interphone is provided with a general microphone. A through hole matched with an antenna of the interphone is formed in the upper surface of the protective shell; the antenna of the interphone penetrates through the through hole and extends to the upper portion of the protective shell, a rubber sleeve is fixedly connected to the left side face of the protective shell, an inserting hole is formed in the left side face of the protective shell, a pressing rod is fixedly connected to the inner wall of the rubber sleeve, and the right end of the pressing rod penetrates through the inserting hole and extends into the protective shell. Sound emitted by a user can be concentrated through a sound transmission cylinder, it is ensured that the sound can be completely transmitted to the universal microphone, the antenna of the interphone can extend out of the protective shell through the through hole, the signal quality is ensured, and the phenomenon that the call quality is affected due to the fact that a user cannot hear the sound clearly when the external sound is large is avoided.
