Automatic volume adjusting earphone and earphone volume adjusting method

Abstract

The invention discloses an automatic volume adjusting earphone, comprising an audio signal input unit, a loudspeaker, a microphone, an accessible memory and an arithmetic unit, wherein the audio signal input unit outputs a test audio signal, the loudspeaker receives the test audio signal and generates sound, the microphone receives the sound in antrum auris of human body and outputs a comparison audio signal, the accessible memory accesses the comparison audio signal, the arithmetic unit performs arithmetic processing according to the comparison audio signal to obtain a frequency requiring strengthening, the output audio signal and the frequency requiring strengthening are subjected to arithmetic strengthening and then input to the loudspeaker through the audio signal input unit. The automatic volume adjusting earphone of the invention can show the best acoustic effect to the antrum auris of different users. The invention also discloses an earphone volume adjusting method.

Description

technical field [0001] The invention relates to an earphone, in particular to an automatic tuning earphone and an earphone tuning method. Background technique [0002] The frequency range that the ear can hear is usually between 16 and 1600 Hz. Broadly speaking, as long as it can produce sound, it is called a source, like various audio-visual products, such as walkmans, personal data processors (PDA), MP4 and mobile phones, etc. To produce the sound we can hear, it must be generated and transmitted by related electronic devices, and the electronic signal must be amplified by the speaker to become the sound that our ears can hear. A further statement is that any device that can produce sound and receive electronic signals can be called a speaker. [0003] At present, there are many types of speakers, and one of the flat speakers: earphones is one of the speakers. With the development of electronic technology, various audio-visual products, such as walkmans, personal data p...

Problems solved by technology

[0004] However, because the shape and structure of each person's ears are different, some people have deeper ear canals, some people have wider ear canals, the effects caused by the outer ear, ear canal, etc., will make the sound in each person's ear canal There are different sound performances. Therefore, the same product has the same sound quality performance during the test, but after it reaches the user's hands, it produces different sound quality problems, which seriously affects the sound quality performance of the earphones and users. auditory
