The utility model discloses an ear cup cavity and a corresponding earphone, the ear cup cavity comprising: a speaker face shell (), a speaker cavity (), a speaker () and a rear shell (); the speaker cavity () is an annular labyrinth type structure which is fixed on the speaker face shell (); the speaker face shell () is provided with the first air port () through which air passes and enters into the speaker cavity (); the second air port () through which air enters into the speaker cavity () is arranged on the position of the speaker cavity () corresponding to the first air port (); the rear shell () is a bowl-shaped structure for accommodating the speaker cavity () and the speaker (). The ear cup cavity and corresponding earphone provided in the embodiments of the utility model can timely release superfluous air gathered in the front cavity of the earphone, control the air release process well and avoid the generation of new noise so as to ensure clear sound played from the earphone and improve the user experience.

Earpiece casing cavity and corresponding earphone

The present invention relates to a type of vibrating membrane for speakers comprising the vibrating membrane body which comprises: A bottom layer used to reinforce the low frequency, a surface disposed on the said bottom layer, a composite metal layer used to ensure vibration uniformity, and a composite platy layer used for HF compensation disposed between the said bottom layer and the said composite metal layer. A type of speaker with the structure of the said vibrating membrane is also disclosed in the invention. Application of the vibrating membrane for speakers and the speaker using the said vibrating membrane as claimed in the invention could be such as to: enable excellent transient response speed, ensure vibration uniformity and obtain flat response in the working area; eliminate MF (medium frequency) and HF (high frequency) resonance to meet the full frequency band requirements of the headphone speakers; boast good flexural behavior to make the speaker structure more stable and less prone to deformation, thereby extending the service life and promoting the quality of the product.

The utility model provides a headphone, comprising a headband, left and right two ear pads and a holder. Two ends of the headband are separately provided with a fixing component, the fixing component includes a conductor block; the holder is made of the conductive material, of which one end is respectively connected with the left and right two ear pads fixedly and the other end is respectively connected with the fixing components in a sliding way, and the conductor block is pressed against the holder; in the ear pads, the first group of signal wires is connected to the holder electrically; in the fixing components, the second group of signal wires is connected with the conductor block electrically. The headphone provided in the utility model replaces the exposed lead with the conductive holder which is used as the medium for the audio signal transfer between the left and right two ear pads, thus eliminating the exposed lead on the headphone, simplifying the structure and avoiding the risk of broken circuit due to the damage of the exposed lead in use previously.

Headphone

This invention relates to an earphone with a movable push rod structure, which comprising a housing, a sound-emitting unit assembled inside of the housing, and a sound duct connected to the sound-emitting unit for sound transmission, and an earplug connected to the sound duct, with an air duct assembled on the housing for the flow of air inside and outside the earphone, as well as a movable push rod assembled inside the housing and connected with the housing for adjusting air flow condition of the air duct. A completely sealed earphone can be achieved when the push rod is pushed to block the air duct, or an open earphone can be achieved when the push rod is separated from the air duct. This invention has advantages of convenient and flexible regulation of sound modes of the earphones, which can be applied to users who have different requirements for sounds, and also a broader range of applications.
