The invention provides a bionic full-open ear concha gain sound guide device and a use method thereof. The bionic fully open ear concha gain sound guide device and its use method include an earphone body capable of fixing the helix on the auricle and an audio power amplifier, which are arranged on the earphone body and can extend into the ear concha cavity and the ear The edge of the first cavity is bonded to form a special-shaped sound guide device that semi-encloses the space. The earphone body includes an earphone upper shell, and the earphone lower shell and the fixed helix are fixed with the earphone upper shell. The earphone resonance chamber surrounded by the shell and the earphone lower shell. The bionic full-open ear concha gain sound guide device and its use method provided by the present invention have the advantages of greater sound pressure gain, closer sound quality, and more natural listening effect, and can prevent cold and keep warm in winter, and the installation is relatively simple. It is relatively fast and can adapt to the advantages of multi-season use.
Description
technical field [0001] The invention relates to the technical field of sound guide devices, in particular to a bionic fully open ear concha gain sound guide device and a method for using the same. Background technique [0002] The earphones currently on the market are generally divided into three types: fully open, semi-open and sealed. Among these three conduction methods, only the fully open is closer to the normal listening effect. Listening to the physiological laws of sound, in the process of sound wave transmission, many acoustic phenomena have occurred: sound collection, front reflection, back reflection, normal mode, superposition of sound waves, resonance space, pinna effect, reflected sound, direct sound , the quarter resonance phenomenon of the outer ear, etc. [0003] As far as the sound guide of fully open earphones is concerned, if the edge size and geometry of the sound guide port of the earphone can be changed as close as possible to the edge of the ear conc...
