Problems solved by technology

[0002] Existing mobile phones and telephones are sent and answered by the microphone and the receiver. When the call is made, the sound signal sent by the receiver is collected by the microphone of the microphone and converted into an electrical signal and an electromagnetic wave signal by the phone. Answering, because the earpiece is close to the ear, the sound is small and will not leak out. In order to make the other party hear clearly when speaking, the sound wave signal of the speaking must have a certain intensity, and people around will inevitably hear it. The occasion is very inconvenient. On the one hand, it may disturb the people around; Qing Shihua

Embodiment Construction

[0010] Referring to Fig. 1, 2, the design of mouthpiece 1 can refer to the mouthpiece of spirometer, can realize the four weeks of sealing mouth, and inner space will leave leeway for the movement of lips when speaking, so that speaking is convenient. Mouth 1 can directly be made with the material that has sound-proof function, also can be made of general material and then outer cover sound-proof material, in order to make the contact part of mouth and face available some soft materials when sealing the mouth around and speaking comfortably , but it cannot affect the sound insulation effect. The muffler 2 and the mouthpiece 1 will be closely connected, and the redundant sound waves when speaking will enter the muffler through the sound wave propagation port 5 and then pass to the air. After the sound wave of speaking passes through, the energy of the sound wave is effectively weakened. Talking tube 3 is a flexible empty tube with two ends, and sound waves can propagate therei...

Abstract

The invention comprises a sound-receiving mouth, a sound eraser, a speaking tube and a adapter. When answering a call, the sound-receiving mouth touches the user's mouth such that the sound can't be released out from the microphone and is only transmitted in the sound-receiving mouth; one portion of the sound signals is transmitted to the microphone of the mobile phone via the adapter.

Description

technical field [0001] The invention relates to a microphone muffler, in particular to a device capable of preventing the voice of a mobile phone or a telephone from being transmitted outside. It belongs to communication equipment. Background technique [0002] Existing mobile phones and telephones are sent and answered by the microphone and the receiver. When the call is made, the sound signal sent by the receiver is collected by the microphone of the microphone and converted into an electrical signal and an electromagnetic wave signal by the phone. Answering, because the earpiece is close to the ear, the sound is small and will not leak out. In order to make the other party hear clearly when speaking, the sound wave signal of the speaking must have a certain intensity, and people around will inevitably hear it. The occasion is very inconvenient. On the one hand, it may disturb the people around; Qing taught the words. Contents of the invention [0003] The purpose of ...
