A display apparatus includes: a display module including a display panel configured to display an image, a vibration plate on a rear surface of the display module, a connection member between the rear surface of the display module and the vibration plate, at least one vibration module on the vibration plate, and an enclosure between the display module and the vibration plate, the enclosure being spaced apart from the vibration module, the enclosure surrounding the vibration module.

A speaker box includes a housing and a speaker unit accommodated in the housing. The speaker unit includes a diaphragm configured to vibrate and sound. The diaphragm is spaced from the housing to form a front sound cavity therebetween. The speaker box further includes a sound transmitting channel communicating the front sound cavity with outside. The front sound cavity and the sound transmitting channel cooperatively form a front cavity of the speaker box. A sound absorption layer is disposed at a portion of the housing facing the front cavity. The sound absorption layer includes a micro-porous structure. When the sound wave passes through the front cavity, the sound absorption layer is capable of absorbing the resonance vibration of the front cavity in high frequency, thus suppressing the amplification of the sound distortion due to the resonance vibration of the front cavity and improving the acoustic performance of the speaker box.

Disclosed is a sheet-shaped air absorbent for a speaker-box system using porous carbon fibers and a speaker-box system including the same, wherein an air absorbent for a speaker-box system includes at least one sheet member, and the sheet member was made by weaving fibers comprising a porous carbon-based substance or a sheet member with at least two layers, and the sheet member was made by weaving fibers comprising a porous carbon-based substance.

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

The present disclosure provides a loudspeaker module, comprising a housing and a loudspeaker unit accommodated in a space of the housing, wherein the loudspeaker unit divides the space of the housing into a front sound cavity and a rear sound cavity, a through hole penetrating the housing is provided on the housing at a position corresponding to the front sound cavity, the loudspeaker module further comprises a cover plate covering the through hole, the cover plate comprising at least one metal foam layer and at least one metal sheet layer. Compared with the related art, the cover plate comprises the metal foam layer, so as to weaken the resonance effect of the loudspeaker module and to reduce the distortion of the loudspeaker module, thereby improving the acoustic performance of the loudspeaker module.

The present disclosure provides an earphone including a core module. The core module may include a core housing and a core. The core housing may include a bottom wall and an annular peripheral wall. When a user wears the earphone, the bottom wall may face the head of the user. One end of the annular peripheral wall may be integrally connected with the bottom wall, the other end of the annular peripheral wall that is away from the bottom wall includes an opening, and the core may be disposed in the core housing through the opening. The core may include a magnet configured such that the core module is attachable to a magnetic object through one side of the bottom wall.

A system includes a speaker enclosure, a speaker in the speaker enclosure, and a meta cell. The meta cell includes an opening on a first end connected to the speaker enclosure, and a closed cavity on a second end.

An acoustic apparatus includes: a three-dimensional network structural body that is an aggregate of filaments that are made of a resilient resin, each randomly looped or curled, fused to each other, and intertwined with each other; an at least one speaker that generates acoustic waves; and a board-like resonance board. The three-dimensional network structural body has a front surface that is held in direct or indirect contact with a human body, and an inner surface that faces the front surface. The at least one speaker includes a vibrating portion that faces the inner surface of the three-dimensional network structural body, and a frame portion that holds the vibrating portion while allowing the vibrating portion to vibrate. The frame portion is mounted to one side surface of the board-like resonance board through intermediation of a resilient mounting material.

This application provides a speaker and a mobile terminal. The speaker includes a housing and a kernel located in the housing, where there is a front cavity and a rear cavity in the housing, the front cavity is in communication with the outside, and the rear cavity is an isolated cavity. In addition, to reduce a space area occupied by the entire speaker, the front cavity and the rear cavity are disposed in a stacked manner when being disposed. Specifically, the front cavity and the rear cavity are at least partially stacked along a thickness direction of the kernel. Therefore, the rear cavity is disposed in space of the entire speaker in the thickness direction of the kernel, to reduce an area occupied by the entire speaker in the mobile terminal on the premise that a size of the rear cavity meets a requirement.
