Abstract

The present invention provides an ear type treble compensation headphone. The ear type treble compensation headphone includes a rear cover, an electromagnetic sounding body, a resonant cavity, a piezoelectric vibrating body, and a front cover. The front cover is provided with an extending sound track that can be put in an ear canal. The piezoelectric vibrating body is disposed in the extending sound track. The electromagnetic sounding body is disposed in the resonant cavity. The front cover and the rear cover respectively cover at two ends of the resonant cavity. The piezoelectric vibrating body includes a fixing board, a piezoelectric ceramic oscillator, and an elastic damper. One end of the piezoelectric ceramic oscillator is fixed on the fixing board. The elastic damper is stuck on the piezoelectric ceramic oscillator. The fixing board is fixed in the extending sound track, so that the piezoelectric ceramic oscillator forms a single suspended arm beam structure. The piezoelectric vibrating body is put in the extending ear canal, thereby facilitating controlling high-frequency response separately. The extending ear canal can improve sound directivity. A fixing manner of the piezoelectric ceramic oscillator is the single suspended arm beam structure, the vibrating displacement is large, compared with surrounding fixed working manners, when same vibration is needed for improving frequency property, the piezoelectric ceramic can be thicker, and the manufacture of the piezoelectric ceramic is easier.

Description

technical field [0001] The invention relates to earphones, in particular to an in-ear type treble compensation earphone. Background technique [0002] With the wide application of high-quality smart phones, Pads and other portable electronic products, people have higher and higher requirements for earphones that can be used in conjunction with them. While requiring them to be small in size, they are also required to be able to reproduce various sound effects realistically. High-fidelity sound quality performance. [0003] In addition, regardless of the above-mentioned electronic products, in order to allow users to listen to the sound signals provided by the electronic products without disturbing others, earphones have become a necessary accessory for each electronic product. In addition, earphones also provide better sound for the listener. Transmission, so that the listener can clearly hear and understand the sound content. [0004] In-ear headphones, also known as ear c...
