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.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus may include an earphone core including at least one acoustic driver for outputting sound though one or more sound guiding holes set on the acoustic output apparatus, a controller configured to cause the at least one acoustic driver to output sound, a power source assembly configured to provide electrical power to the earphone core, the one or more sensors, and the controller, and an interactive control component configured to allow an interaction between a user and the acoustic output apparatus.

An acoustic device with an open audio device structure that is configured to be carried on the head or upper torso of a user, a housing carried by the open audio device structure, the housing having opposed first and second ends, a flat diaphragm in the housing and comprising a front face and a rear face, the diaphragm configured to radiate front acoustic radiation from its front face and rear acoustic radiation from its rear face, wherein the front and rear acoustic radiations are out of phase, structure that supports the diaphragm such that the diaphragm can move relative to the housing, a primary magnet adjacent to the rear face of the diaphragm, a magnetic circuit that defines a path for magnetic flux of the primary magnet, a voice coil that is exposed to the magnetic flux and is configured to move the diaphragm up and down along a radiation axis that is normal to the front face of the diaphragm, and first and second sound- emitting outlets in the housing, wherein the first sound-emitting outlet is in or proximate the first end of the housing and is acoustically coupled to the front face of the diaphragm so as to emit front acoustic radiation into an acoustic space, and wherein the second sound-emitting outlet is in or proximate the second end of the housing and is acoustically coupled to the rear face of the diaphragm so as to emit rear acoustic radiation into the same acoustic space.

An open audio device with a body that has an inner surface that is configured to be located behind an outer ear of a user and in contact along a length of the body at multiple locations of at least one of the outer ear and the head proximate the intersection of the head and the outer ear. The inner surface of the body lies generally along a decaying helix. An acoustic module is carried by the body and is configured to be located against the outer ear above the ear canal opening.

The present disclosure discloses an acoustic output device. The acoustic output device may include a first acoustic driver including a first diaphragm; a second acoustic driver including a second diaphragm; a control circuit electrically connected with the first acoustic driver and the second acoustic driver respectively, the control circuit provides a first electrical signal for driving a vibration of the first diaphragm, and a second electrical signal for driving a vibration of the second diaphragm, and a phase of the first electrical signal and a phase of the second electrical signal are opposite; and a housing supporting the first acoustic driver and the second acoustic driver, wherein a sound generated by the vibration of the first diaphragm is radiated outward through a first sound guide hole on the housing, and a sound generated by the vibration of the second diaphragm is radiated outward through a second sound guide hole on the housing.

The present disclosure relates to a waterproof open earphone. The waterproof open earphone may include a housing, at least one button, at least one elastic pad, and at least one pair of speaker units. The housing may be placed on a head or at least one ear of a user while not blocking an ear canal of the user. The at least one button may be set on the housing, wherein each of the at least one button corresponds to a button hole. The at least one elastic pad may correspond to the at least one button, respectively, wherein each elastic pad prevents the corresponding button from moving relative to the button hole. Each pair of the at least one pair of speaker units may generate sound within a frequency range from two sound guiding holes through two sound guiding tubes.

A wearable audio device including first and second transducer modules is provided. The first transducer module may include a first transducer. The first transducer module may further include a first enclosure having a top side defining a first slit and a bottom side defining a second slit. The first enclosure may be configured to guide a first sound pressure through the first slit, and a second sound pressure through the second slit. The second transducer module may include a second transducer. The second transducer module may include a second enclosure having a top side defining a third slit and a bottom side defining a fourth slit. The second enclosure may be configured to guide a third sound pressure through the third slit, and a fourth sound pressure through the fourth slit. The third and fourths slit may be arranged diagonally opposite the first and second slits, respectively.

A speaker module adapted to be disposed on a wearable device. The speaker module includes at least one driving unit and an enclosure. The driving unit is configured to produce sound. The enclosure contains the driving unit and has a front chamber and a rear chamber. The front chamber and the rear chamber are individually located at two opposite sides of the driving unit. The enclosure has a front opening, a first rear opening, and a second rear opening. The front opening communicates with the front chamber. The first rear opening and the second rear opening individually communicate with the rear chamber. A sum of sound outputted from the front opening, the first rear opening, and the second rear opening has directivity.

The present disclosure relates to a loudspeaker. The loudspeaker may include a loudspeaker mechanism, a fixing mechanism, and a connector. The loudspeaker mechanism may be configured to generate a vibration signal and transmit the vibration signal to the human body. The fixing mechanism may be configured to support and maintain the position of the loudspeaker mechanism. The connector may be configured to connect the loudspeaker mechanism with the fixing mechanism. The loudspeaker mechanism may at least include a first fixed position and a second fixed position. The first fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a non-working state. The second fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a working state. The connector may be configured to switch the loudspeaker mechanism between the first fixed position and the second fixed position.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus may include an earphone core including at least one acoustic driver for outputting sound though one or more sound guiding holes set on the acoustic output apparatus, a controller configured to cause the at least one acoustic driver to output sound, a power source assembly configured to provide electrical power to the earphone core, the one or more sensors, and the controller, and an interactive control component configured to allow an interaction between a user and the acoustic output apparatus.
