Embodiment Construction

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

[0021] Such as figure 1 As shown, many small holes are opened on the pickup head 1 to allow sound to enter. When collecting voice signals, sound waves pass through the metal pickup head 1 to vibrate the outer diaphragm 2, and the movement of the outer diaphragm drives the movement of the ossicles 3. , the ossicle 3 is connected to the inner diaphragm 5, causing the vibration of the inner diaphragm 5, and the inner diaphragm 5 causes the liquid in the artificial cochlea 8 and the basement membrane 6 to vibrate, thereby causing the traveling wave to propagate along the basement membrane 6, and the basement membrane 6 is Designed to imitate the basilar membrane of the human ear, the head is pointed and the tail is wide. Different frequencies of sound have resonance peaks at different positions on the basilar membrane. 1.79cm and 2.08cm places a...

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 device, in particular to a pickup structure imitating the structure of the human ear. Background technique [0002] Speech recognition and other intelligent processing of sound, while technologically advanced, still has not surpassed the capabilities of the human ear. Therefore, studying the hearing principle of the human ear and using bionic technology to manufacture a bionic pickup can obtain information consistent with the human ear's hearing from the source, which is more conducive to bionic speech recognition and other intelligent sound processing. The cochlea of ​​the human ear acts as a natural sound filter, imitating the cochlea to design a pickup can make the collected data more in line with the actual situation of human hearing. Using such raw data can bring great benefits to subsequent data processing and recognition. Come more convenient. Contents of the invention [0003] The purpose of the pr...
