An earphone includes a housing and a microphone. The microphone is provided in the housing. The housing includes a hole that leads to the microphone. The hole has a shape in which a cross-sectional area expands, toward a back of a head of a user wearing the earphone, from the microphone toward an outside of the housing. The housing, in a case of being worn by the user, is located farther away from an external earhole, in an outside direction from a side of the head, than from an ear of the user.

Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

An earphone control method is applied to an earphone box provided with a first electrical contact, when the first electrical contact is in a charging state, the first electrical contact is configured for charging the earphone, and when the first electrical contact is a communication state, the first electrical contact is configured for establishing communication between the earphone box and the earphone, the method includes: in responding to that the first electrical contact is in the charging state, and the earphone box detects that a communication requirement exists between the earphone box and the earphone, adjusting a voltage level of the first electrical contact to send preset signals to the earphone; and upon receiving a response signal fed back by the earphone based on the preset signals, switching the first electrical contact to the communication state. An earphone box, an earphone and a computer-readable storage medium are also disclosed.

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook, a core housing, and a circuit housing. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve. The protective sleeve may be made of an elastic waterproof material. The core housing may be used for accommodating an earphone core. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The circuit housing may be used for accommodating a control circuit or a battery. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate. The vibration of the earphone core may generate a driving force to drive a housing panel of the core housing to vibrate. The driving force may be not parallel to a normal line of the housing panel. In the present disclosure, the core housing may elastically abut against the protective sleeve surrounding the ear hook to improve the overall waterproof effect of the loudspeaker apparatus and simplify the manufacturing and assemble process of the loudspeaker apparatus.

Provided is an acoustic device to be worn on an ear for use, the acoustic device including a nozzle having a transducer installed therein, the transducer serving as a sound source, and a housing attached to a base portion of the nozzle and having an electronic circuit and a battery housed therein, the electronic circuit being configured to drive the transducer. When the acoustic device is worn on the ear with a distal end of the nozzle inserted into an earhole and the base portion of the nozzle positioned outside of the earhole, a passage continuously extending between the base portion and the distal end of the nozzle is secured to allow an external sound to be taken in through the passage.

The technology provides a multi-body earpiece suitable for use as an in-ear sensor system, which can be used for biometrics or a human-computer interface. The multi-body earpiece includes two body elements connected together by a flexure. These components provide at least 3 points of contact along different parts of the outer ear, in which the flexure is tethered to the two bodies and arranged to lock them in place during wear. In addition to having stability from moving while minimizing sound occlusion, this arrangement enables any electrodes for the on-board sensor(s) to remain in contact with the skin of the ear, and provide as many contact points in desired areas as the electronics dictate for the signals of interest.

The disclosure provides a neck-hanging type headphone. The neck-hanging type headphone includes a headphone body, wherein the headphone body is detachably connected to one end of an ear-hanging connector, a first neck-hanging piece or a second neck-hanging piece or a third neck-hanging piece or a fourth neck-hanging piece is arranged at the other end of the ear-hanging connector through a fixing mechanism, and the first neck-hanging piece, the second neck-hanging piece, the third neck-hanging piece and the fourth neck-hanging piece are detachably connected to the ear-hanging connector. According to the solution, the corresponding first neck-hanging piece or second neck-hanging piece or third neck-hanging piece or fourth neck-hanging piece may be selected for wearing according to different situation requirements. The neck-hanging type headphone is applicable to different scenarios and requirements, and has the advantages of wide applicability, convenience in use and the like.

Some embodiments disclose a customizable covering device for earphones. In some embodiments, the device can removably engage on to the earphones with arms of the coupling portion. A cap portion can extend from the coupling portion and allows a user to add protective, decorative, sound isolating and other additional features that are not present in conventional earphones.

Disclosed is an open headphone, comprising a front cover, a loudspeaker unit and a rear housing. A front headphone chamber is formed between the front cover and the loudspeaker unit. A rear headphone chamber is formed between the loudspeaker unit and the rear housing. The front cover is provided with several sound output holes. The loudspeaker unit has a middle loudspeaker hole which is through in a front-rear direction. The rear housing is also provided with a sound guide tube. The rear end of the sound guide tube is in communication with the external space of the headphone. The front end of the sound guide tube is inserted in the middle loudspeaker hole and at a distance from a vibrating diaphragm, and the distance is larger than a maximum vibration displacement of the vibrating diaphragm. The open headphone of the present disclosure has high-quality bass performance, and other advantages, such as that the sound field is open and natural, that the user is not easy to become fatigue after long-term use, and that it will not cause damage to people's hearing. By inserting the front end of the sound guide tube in the middle loudspeaker hole, which is able to reduce the volume of the rear headphone chamber, so as to make the whole headphone small and easy to carry.
