Embodiment Construction

[0034] Next, with reference to the accompanying drawings, the embodiment of the earphone of the present invention will be described.

[0035] exist figure 1 and figure 2 In , mark 3 represents the drive unit that is driven by the sound signal to emit sound. The drive unit 3 is housed in the housing 1 . Reference numeral 2 denotes a housing that is connected with the housing 1 on the back side of the drive unit 3 to form a chamber 5 . The rear space 12 of the drive unit 3 of the housing 1 communicates with the chamber 5 via the connecting channel 4 . In addition, an acoustic resistance material 7 is provided in the cavity 5 to block the connection channel 4 . The main components of the earphone in the embodiment of the present invention include the drive unit 3 , the housing 1 , the shell 2 , the connecting channel 4 and the acoustic resistance material 7 . Hereinafter, these components will be described in detail.

Abstract

The invention provides an earphone which has a housing for reducing the backpressure of a vibrating plate of a driving unit, further improving the acoustic characteristic by using acoustic-resistant materials, reducing ununiform distribution of acoustic resistance values by improving the configuration structure of the acoustic-resistant materials and also improving the balance of the play frequency from a low pitch to a middle pitch and a high pitch. The earphone of the invention comprises a driving unit (3) which is driven by a sound signal to emit a sound; a housing (1) for accommodating the driving unit (3); a housing (2) which is connected with the housing (1) at one side of the back of the driving unit to form a cavity (5); a connecting channel (4) for communicating the space (12) at the back of the driving unit (3) in the housing (1) and the cavity (5); and an acoustic-resistant material (7) covering the connecting channel (4).

Description

technical field [0001] The invention relates to an earphone capable of playing sound signals in a balanced and fidelity manner from low pitch to high pitch. Background technique [0002] For example, in an earphone with a dynamic drive unit, in order to improve the playback capability in the low range, a back chamber integrated with a casing housing the drive unit is provided, and a small hole is formed in the back chamber. And, in the earphone, the back chamber is communicated to the external space through the hole. The back chamber refers to a space provided on the rear side of the drive unit. Earphones having such a structure are called open-air earphones. In order to reduce the lowest resonant frequency of open dynamic earphones to expand the playing range of the bass range, and to improve acoustic characteristics, known earphones adopt a structure that is provided with a channel leading to the back space of the drive unit. However, in this case, there arises a proble...
