Embodiment Construction

[0020] The structure of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, many small holes are opened on the pickup 1 to allow the sound to enter. When the voice signal is collected, the sound wave passes through the metal pickup 1 to make the outer diaphragm 2 vibrate, and the movement of the outer diaphragm drives the ossicular 3 to move. , the ossicular 3 is connected to the inner diaphragm 5, causing the vibration of the inner diaphragm 5, and the inner diaphragm 5 causes the vibration of the liquid in the simulated cochlea 8 and the basilar membrane 6, thereby causing the traveling wave to propagate along the basilar membrane 6, and the basilar membrane 6 is The basement membrane of the human ear is designed with a wide head, tip and tail. Different frequencies of sound have formants at different positions on the basement membrane. Above the basement membrane, the logarithmic sca...

Abstract

The invention relates to a sound recorder, in particular to a bionic pickup. An outer diaphragm (2) is disposed in a pickup head (1) and adhered to an inner diaphragm (5) through an artificial ossicle (3). The inner diaphragm (5) is hermetically disposed at one end of a simulation cochlea (8) which is a cylinder filled with liquid. A triangular elastic base film (6) is axially arranged inside the cylinder. One bottom edge of the base film (6) overlaps the bottom of the cylinder. A sharp corner of the base film (6) is adhered to the inner center of the inner diaphragm (5). From the sharp corner of the triangular base film (6) to the bottom of the cylinder, on one side wall of the simulation cochlea (8), a plurality of miniature microphones (7) are arranged at certain intervals. The miniature microphones (7) are lead out of the pickup through their respective leads (9). The artificial ossicle (3) is composed of three thin rods hinged in a Z shape through flexible hinges (4). The bionic pickup imitating the structural design of human ear can collect multiple voices under different frequencies, is better satisfactory to auditory reality in human, and is convenient for subsequent intelligent handling of data.

Description

technical field [0001] The invention relates to a sound recording apparatus, in particular to a pickup structure imitating the structure of the human ear. Background technique [0002] Speech recognition and other intelligent processing of sounds, despite great advances in technology, are still nowhere near the capabilities of the human ear. Therefore, studying the auditory principle of the human ear and using bionic technology to manufacture bionic pickups can obtain information consistent with human hearing from the source end, which is more conducive to bionic speech recognition and other intelligent processing of sounds. The cochlea of ​​the human ear acts as a natural sound filter, imitating the cochlea to design the pickup, which can make the collected data more in line with the actual situation of human hearing. Using such raw data, it can be used for subsequent data processing and identification. more convenience. SUMMARY OF THE INVENTION [0003] The purpose of ...
