Detailed Description

In order to make the technical solution of the present invention more apparent, the present invention is further described in detail with reference to the following examples, and it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to fig. 1-4, this embodiment is taken the product of wearing at the left ear as an example, and an audio recording device includes casing 1, and casing 1 is half-in-ear structure, and casing 1's inside is provided with sound chamber 2 and pickup cavity 3 respectively.

Install microphone 4 in the sound-collecting cavity 3, the rear side of casing 1 is provided with pickup mouth 5, pickup mouth 5 and sound-collecting cavity 3 intercommunication. The structure of the sound-collecting chamber 3 highly imitates the auditory canal of the human ear, and the microphone 4 is arranged at the auditory canal structure of the middle ear of the human ear. In use, sound signals are first reflected and filtered by the pinna of the human ear, then enter the pick-up chamber 3, are received by the microphone 4 and are recorded. Therefore, the utility model discloses the mode of receiving sound signal is close the mode that real people's ear heard sound, can improve the position sense and the spatial sensation of the sound of recording.

The utility model discloses still include external digital integrator 6 and intelligent terminal equipment 7. The microphone 4, the digital integrator 6 and the intelligent terminal device 7 are electrically connected in sequence. The digital integrator 6 integrates the audio tracks recorded at the two ears through the audio interface, the intelligent terminal device 7 controls the digital integrator 6 to merge, and the manufactured audio is transmitted to the intelligent terminal device 7 through the audio interface to be stored. The integrated recording of the microphone 4 and the digital integrator 6 can process the audio in real time, and save the manufacturing time. Therefore, the utility model discloses have the convenient advantage of use in the aspect of the audio frequency is recorded.

The loudspeaker 8 is arranged in the sound cavity 2, and the sound cavity 2 is arranged on the front side of the sound-collecting cavity 3. The utility model discloses be provided with speaker 8 at the part of going into the ear, can realize the function of traditional earphone broadcast pronunciation.

The front end of the sound cavity 2 is provided with a sound outlet 9, and the ear inlet side of the shell 1 is provided with an ear inlet 10. The function of both the sound outlet 9 and the sound inlet 10 is to allow sound to be emitted from the sound chamber 2 and into the ear cavity. The problem that the traditional earphone is insufficient in bass performance can be solved by additionally arranging the ear inlet 10, and the tone quality of the earphone is effectively improved.

The sound cavity 2 is completely isolated from the pickup cavity 3 through the sound insulation pad 11, so that two functions of voice playing and audio recording are not interfered with each other and can be carried out simultaneously.

The air leakage port 12 on the upper side of the sound cavity 2 can balance the air pressure in the ear cavity, and the definition of played sound is improved.

Pickup mouth dust screen 13 is installed to pickup mouth 5, can avoid the dust to get into pickup cavity 3, influences the work of microphone 4.
