Embodiment Construction

[0032] Hereinafter, an embodiment of the earphone of the present invention will be described with reference to FIG. 1 and FIG. 2 . The same reference numerals are assigned to the same components as those of the conventional headphone example shown in FIG. 3 .

[0033]In FIG. 1 , a flange portion 22 is formed at the open end of a bottomed cylindrical earphone case 20 , and a ring-shaped head pad 3 is fixed to the outer side (left side in FIG. 1 ) of the flange portion 22 . When the user uses the earphone, the outer end surface of the head pad 3 contacts the side of the user's head, and the user's ear 13 is located in the space surrounded by the head pad 3 . The earphone part 5 is fastened inside the earphone housing 20 via an annular carrier 35 . The earphone part 5 has a flat shell-shaped frame 6, a flatter shell-shaped yoke 7 with a diameter smaller than the frame 6 embedded in the inner bottom of the frame 6, a flat magnet 8 fixed on the inner bottom center of the yoke 7, f...

Abstract

An earphone is equipped with a loudspeaker component driven by musical sound signal, a microphone for detecting ambient noise, a piezoelectric element for driving framework of loudspeaker component by noise elimination signal generated based on noise signal detected by microphone. The piezoelectric element is disposed between the framework of loudspeaker component and earphone housing, the two sides of which is combined with the framework and the earphone housing. Therefore, the earphone with weak electric coupling of noise elimination signal and musical sound signal, less influence of noise elimination signal to musical sound signal is obtained, both the power amplification circuit of noise elimination signal and musical sound signal can not be load for each other, which is capable of listening reproduction sound based on musical sound signal with excellent quality even if the embedded battery is expended and the noise elimination circuit is out of working.

Description

technical field [0001] The present invention relates to earphones capable of reducing external noise. Background technique [0002] Along with the popularization of portable music players, earphones for personal listening to music are also widely popularized. Portable music players are mostly used on streets where the noise level is high, in vehicles such as trains and buses, and external noise can also be heard through headphones along with the music reproduced by the player. If you listen to music in the noise, sometimes the music is drowned by the noise, so the user has to increase the volume to listen to the music. If the volume is too high, the sound leaks from the earphones to the outside, sometimes making people around feel uncomfortable. In addition, even if high-quality musical sound is reproduced using headphones, noise disturbance from the outside may affect the musical sound, degrading the quality of the reproduced sound heard by the user. [0003] Therefore, n...
