A headset includes a speaker, such as a side firing dipole speaker. The headset includes a front chamber that receives sound waves from a first side of the speaker and a rear chamber that receives sound waves from a second side of the speaker. A control leak channel connects the front chamber and the rear chamber. An acoustic mesh may be located within the control leak channel. The speaker configuration is configured to reduce total harmonic distortion of the speaker, particularly in ranges such as 3-6 kHz, while maintaining the broadband efficiency of the speaker.

An audio assembly provides audio content to a user. The audio assembly comprises an elongated body, a diaphragm, a transducer, and a plurality of vent assemblies. The elongated body has a first end and a second end opposite the first end. The diaphragm is within the elongated body and pivots about a pivot location that is proximate the second end. The transducer is within the elongated body and is positioned proximate to the first end. The transducer causes the diaphragm to pivot about the pivot location such that the diaphragm generates a positive acoustic pressure wave from a first surface of the diaphragm and a negative acoustic pressure wave from a second surface of the diaphragm. The plurality of vent assemblies are along one or more surfaces of the elongated body, and are configured to vent the positive acoustic pressure wave and the negative acoustic pressure wave.

A compression driver including an acoustic outlet duct, a magnetic assembly having a permanent magnet and an air gap, a vibrating membrane with a movable coil adapted and configured to move inside the air gap, where the vibrating membrane includes a first face facing a first chamber communicating with the outlet duct, where the first chamber is a compression chamber, a second face opposite to the first face and facing a second chamber communicating with the air gap and opposite to the first chamber, where the compression driver includes at least one acoustic connection duct which puts in communication the second chamber with the acoustic outlet duct.

Disclosed is an earphone, which includes a housing defined with a first sound hole, a second sound hole, and a resonant cavity communicating the first sound hole and the second sound hole inside the housing; and a loudspeaker in the resonant cavity, having a first sound emitting surface corresponding to the first sound hole, and a second sound emitting surface facing the first sound emitting surface, where sound emitted from the second sound emitting surface pass to the second sound hole through the resonant cavity.

An acoustic device with an open audio device structure that is configured to be carried on the head or upper torso of a user, and an electro-acoustic transducer carried by the open audio device structure and comprising a flat rectangular diaphragm comprising a front face and a rear face, the diaphragm configured to radiate front acoustic radiation from its front face and into a front acoustic volume that has a first sound-emitting outlet proximate a first corner of the transducer and further configured to radiate rear acoustic radiation from its rear face and into a rear acoustic volume that has a second sound-emitting outlet proximate a second corner of the transducer that is diagonally opposite the first corner.

The embodiments of present disclosure disclose a loudspeaker. The loudspeaker may include an ear hook including a first plug end and a second plug end. The ear hook may be surrounded by a protection sleeve, and the protection sleeve may be made of an elastic waterproof material. The loudspeaker may include an earphone core housing configured to accommodate the earphone core, and the earphone core housing may be fixed to the first plug end through plugging, and may be elastically abutted against the protection sleeve elastically.

The present disclosure provides an acoustic output apparatus. The acoustic output apparatus may include an acoustic output component and a supporting structure forming an acoustically open structure that allows the acoustic output component to acoustically communicate with the surroundings. The acoustic output component may include a plurality of acoustic drivers, each of which may be configured to output a sound with a frequency range. At least one of the acoustic drivers may include a magnetic system for generating a first magnetic field. The magnetic system may include a first magnetic component for generating a second magnetic field and at least one second magnetic component. A magnetic gap may be formed between the first magnetic component and the at least one second magnetic component. A magnetic field intensity of the first magnetic field in the magnetic gap may be greater than that of the second magnetic field in the magnetic gap.

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.
