A kind of earphone and a kind of earphone volume adjustment method

Abstract

The invention discloses an earphone. The earphone comprises an earlap; a PCB (Printed Circuit Board) is arranged in the earlap; a slide switch and a MCU (Microcontroller Unit) chip are arranged on the PCB; a bearing is rotatably arranged at one end part of the earlap; an annular rotary body sleeves the outer ring of the bearing; the annular rotary body and the earlap are rotatably connected through the bearing; a plurality of shifting parts are arranged at the end part of the annular rotary body near the earlap; and a rotary handle of the slide switch is correspondingly arranged at the rotation position of the shifting parts. The invention further discloses an earphone volume adjusting method. According to the earphone and the earphone volume adjusting method disclosed by the invention, the number of parts is small; and user experience is good.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to an earphone and a method for adjusting the volume of the earphone. Background technique [0002] Headphones are electro-acoustic products widely used in consumer electronics such as smartphones and computers. With the advancement of society and the upgrading of consumer electronics, especially the popularization of smart phones, consumers have higher and higher requirements for existing consumer electronics, and the requirements for earphones, which are important electroacoustic components of consumer electronics, are also increasing. higher. For example, the operability of headphone function switching and volume adjustment is required to be good. In order to improve product differentiation and operability of headphones, refer to figure 1 , the existing earphones often adopt the following structure: a rotating part 12 is arranged on the ear shell 11, and the r...

AI Technical Summary

Problems solved by technology

[0003] (1) The rotating part and the ear shell rotate through the chute and the sliding buckle. During the rotation, the chute and the sliding buckle have a large contact friction, which makes the rotation effect not smooth, and there are shaking and friction noises;

[0004] (2) During the use of the earphone, the abnormal friction noise between the rotating part and the ear shell is transmitted to the ear, and the noise is harsh, resulting in poor user experience;

[0005] (3) The number of magnets that need to be installed on the rotating part is large, the magnet parts are small, assembly is difficult, and the cost of parts and assembly is high
