Combination glasses type single-channel or double-channel piezoelectric ceramics ossiphone

Abstract

The invention discloses a combination glasses type single-channel or double-channel piezoelectric ceramics ossiphone. The combination glasses type single-channel or double-channel piezoelectric ceramics ossiphone comprises a combination type glasses frame. The combination type glasses frame is formed by combining a lens framework, two glasses legs and supporting legs arranged at the rear ends of the glasses legs. A high-accuracy speech signal processing system and a main high-sensitivity omni-directional ultra-miniature pickup microphone are installed in at least one glasses leg. The high-accuracy speech signal processing system is in electric connection with the main high-sensitivity omni-directional ultra-miniature pickup microphone. The high-accuracy speech signal processing system is connected with a piezoelectric ceramics bone conduction oscillator. The piezoelectric ceramics bone conduction oscillator is arranged outside one glasses leg. The combination glasses type single-channel or double-channel piezoelectric ceramics ossiphone is simple and ingenious in structure, voices can be collected sensitively by the main high-sensitivity omni-directional ultra-miniature pickup microphone, the directionality is good, acoustical signals can be processed by the high-accuracy speech signal processing system in a high-precision and accurate mode, the acoustical signals are effectively converted to mechanical signals through the piezoelectric ceramics bone conduction oscillator, and the voices can be conducted through vibration accurately.

Description

technical field [0001] The invention relates to a combination glasses type single-channel or double-channel piezoelectric ceramic bone conduction hearing aid. Background technique [0002] There are two forms of sound transmission, air conduction and bone conduction, but the final place where the sound is heard is the auditory system of our inner ear. [0003] The sound of human speech and the sound from TV and radio are transmitted to our external auditory canal through the vibration of the surrounding air, causing the tympanic membrane to vibrate and the ossicle chain to move, causing the inner ear lymph to produce liquid wave vibration, stimulating the auditory hair cells of the inner ear, Through the auditory nerve to the auditory center, we can hear the sound. This is the principle of air conduction. [0004] Bone conduction means that the sound is not transmitted through the outer ear and middle ear, but is directly transmitted to the inner ear and auditory nerve thr...
