Problems solved by technology

[0007] a. The measurement parameters are highly specialized and need to be measured in different spaces and environments. The physical parameters and space parameters of the speaker are included in the vibration elimination system at the same time, which increases the complexity and is not easy to meet the requirements at the same time. It is difficult for general users to operate
[0008] b. Not suitable for earphones, only for speakers

Abstract

This invention relates to a passive electric-sound device and a playing device including a playing device and an earphone, among which, the earphone stores an inclusive chip with the electronic acoustic property parameters of frequency response, pulse response, flexibility, frequency-impedance curves, resonance frequency and the maximum sound pressure. The inclusive chip is connected with the PSP of the playing device, DSP fetches data information for the earphone property parameters in the chip, comparing the audio property parameter of the playing signals to regulate the playing signals with the result to finish transmission and play of sound.

Description

technical field [0001] The invention relates to the technical field of digital audio, in particular to a passive electro-acoustic device and a sound playback method thereof. Background technique [0002] At present, in digital audio products, there is little technological improvement in traditional electro-acoustic devices, and people still use the same loudspeaker design pattern since 1910 (the sound coil is attached to a diaphragm, suspended from a large magnet by strong magnets and metal speakers). In the gap of the magnetic field formed by the frame), the same microphone (dynamic, condenser or ribbon) and the same earphone (also known as an earphone, which is a miniaturized speaker), the basic principle has never changed. Many people have tried to change its performance: for example, headphone sensors. It uses rare elements to make stronger magnets, makes special geometric shapes, extremely thin films and maintains a certain mechanical strength, and uses strict producti...
