A kind of high sound quality headphone speaker

Abstract

The invention relates to the technical field of the earphone speaker, particularly to a high-tone-quality earphone speaker comprising a support, a front cover, a rear cover, a magnetic ring, a T-shaped iron, voice coils, and vibration diaphragms. The magnetic ring is fixed in the support; the T-shaped iron is arranged below the magnetic ring; the vibration diaphragms are arranged above the magnetic ring; and the voice coils are fixed on the vibration diaphragms. The front cover and the rear cover sleeve the outside of the support; the inner surfaces of the front cover and the rear cover and the outer surface of the support are in a zero-clearance fit mode; and the front cover and the rear cover can move up and down along the support. The front cover and the rear cover cooperate with the support to form a front acoustic cavity and a rear acoustic cavity. The vibration diaphragms are formed by bonding of bottom membrane fragments and surface membrane fragments; a plurality of wrinkles are arranged at the surfaces of the surface membrane fragments, wherein the cross section areas of the wrinkles are gradually increased from inside to outside. According to the high-tone-quality earphone speaker, requirements of different high frequencies and low frequencies in usage can be met; and the tone quality of the earphone speaker is good.

Description

technical field [0001] The invention specifically relates to the technical field of earphone speakers, in particular to a high-quality earphone speaker. Background technique [0002] The sound cavity is an important part of the earphone speaker. The function of the sound cavity is mainly to eliminate the acoustic short circuit, suppress the acoustic resonance, broaden the frequency response range, and reduce distortion. The volume size of the acoustic cavity structure and the internal sound reflection law can directly affect the sound quality of the sound. In the structure of the earphone speaker, it is divided into a front cavity and a rear cavity. The rear cavity mainly affects the low-frequency part of the ringtone, and the larger the volume of the rear cavity, the better the low-frequency performance of the earphone speaker. The front cavity mainly affects the high-frequency part of the ringtone. The larger the volume of the front cavity, the better the high-frequency ...

AI Technical Summary

Problems solved by technology

[0003] However, the volume of the sound cavity of the current headphone speakers has been fixed after they are produced, and in order to save space, in actual design, the volume of the sound cavity is often limited, resulting in that the high and low frequency performance of the headphone speakers cannot meet the requirements when they are used.

Another point is that the vibration diaphragm of the earphone is generally a thin diaphragm, and the thickness or material of the entire diaphragm is the same, resulting in a large difference in the mid-to-high frequency response. Good response, rich bass, but poor treble response
