HEADPHONE DEVICE AND A METHOD FOR CONTROLLING EQUALIZATION SETTINGS IN THE HEADPHONE DEVICETECHNICAL FIELD
[0001] The present disclosure relates to a headphone and a method for controlling equalization settings in the headphone device.BACKGROUND
[0002] Currently, there are various types of TWS headphones available in the market, such as in-ear TWS headphones and open-ear TWS headphones.
[0003] The structure of in-ear TWS headphones includes an earbud portion that extends into the user's ear canal. The eartip including a speaker or other transducer that outputs audio from an audio source, such as a mobile phone, is inserted directly into the ear canal of the user. The relatively sealed internal environment achieved by the close contact between the eartip section and the user's ear canal prevents sound leakage and prevents external noise from entering the ear canal, thus providing better acoustics.
[0004] The open-ear TWS headphones are constructed without eartip that intrude into the user's ear canal. This design means that the user will not feel a foreign body sensation from the ear canal, resulting in a more comfortable wearing experience.
[0005] However, both types of TWS headphones have their own drawbacks. For example, in the case of in-ear headphones, the tip of the earbud intrudes into the ear canal, which is a foreign body sensation that some users are very uncomfortable with. For the open-ear headphones, there is no closed chamber between the headphones and the user's ear canal, resulting in damage to the sound quality.
[0006] It is often difficult to combine user comfort and good sound quality in a singular headphone design. Users may switch to different headphones depending on the specific usage scenario and current needs. This, in turn, brings about problems in terms of price.

[0061] In order to facilitate the connection of the host module to the earpiece module, an outwardly protruding clip 112 is provided at the edges of the host housing surrounding the host mounting surface 104. A corresponding first slot 228 is provided at an edge of the first earpiece housing surrounding the first earpiece mounting surface 224, as shown in FIG. 8.
