Problems solved by technology

[0004] Therefore, although from the perspective of software technology, although the voice search engine already has powerful keyword search or resolution capabilities, and can even recognize a variety of slang and dialects, because there is no upstream key device that can pick up a noiseless microphone, the voice For many years, smart technology can only stay in the era of toys or games that can be repeated if you make a mistake, or even stay in concept, and cannot promote practical application

Embodiment 1

[0039] Such as figure 1 , 2 The ear canal microphone shown includes an outer end cover 1, a body 2, an isolation muffler cover 3, a pickup 4, and a voice signal line 405. It is characterized in that the body 2 has an integrated cabin 201, an ear canal tube 202, and The eardrum end 203 in the canal tube 202 is equipped with a pickup 4; the isolation muffler sleeve 3 is sleeved on the outer wall of the ear canal tube 202; the right end of the outer end cover 1 has a concave-convex buckle A101, and the left end of the body 2 has a concave-convex buckle B206 The concave-convex buckle A101 of the outer end cover 1 and the concave-convex buckle B (206) of the body 2 are inlaid and engaged with each other.

Embodiment 2

[0041] Such as image 3 , 4 The ear canal microphone shown includes a body 2a, an isolation muffler cover 3, a pickup 6, a voice signal line 405, and a transmission coil 6. The body 2a has an ear canal tube 202 in the shape of a blind hole, and the eardrum of the ear canal tube 202 The end 203 is equipped with a pickup 4; the isolation muffler sleeve 3 is sleeved on the outer wall of the ear canal tube 202.

Embodiment 3

[0043] Such as figure 2 , 4 As shown in the ear canal microphone, the pickup 4 is an electret capacitor transducer; the pickup 4 is mounted on the eardrum end 203 in the ear canal tube 202, the electret membrane surface of the pickup 4 faces the eardrum end 203, and the voice of the pickup 4 The signal pad or electrode is welded with a voice signal line 405.

Abstract

The invention discloses an ear canal microphone, and relates to the voice frequency communication technology. A sound pickup (4) is arranged at an eardrum end (203) of an ear canal cylinder (202), the sound pickup (4) collects eardrum vibration or / and ear canal vibration in an ear canal to recover a voice signal, the eardrum vibration or / and the ear canal vibration is caused by vibration of the vocal cord of a speaker, and is caused through bone conduction, the sound pickup (4) does not collect a sound wave of noise in the external environment of the ear canal of a user, and the obtained voice signal is pure. The ear canal microphone can especially meet the requirement of the voice intelligent control technology for the degree of pureness of a key word, is a front end bottleneck device necessary for promoting practicability of the voice intelligent control technology, and also improves voice communication in the noisy environment.

Description

Technical field [0001] The invention relates to an ear canal microphone, which belongs to audio communication technology. Background technique [0002] The microphone, as a transducer that converts sound waves into electrical signals, has a mature technology, with electret capacitive, moving coil, and carbon crystal structures. The significant disadvantage of the prior art microphone is that it first collects the voice signal including environmental noise, and then performs noise reduction or noise reduction processing on the noise signal. The noise reduction or noise reduction method is more common in 180-degree reverse or multi-directional arrangement of pickups to directly offset or overcome environmental noise through software technology. The microphone in the prior art performs noise reduction or noise reduction remedial measures for the first picked noise, and its noise reduction or noise reduction effect can only meet the needs of using the human brain to determine the co...
