A sounding component in an electronic device includes a box and a sounding system disposed in the box. The sounding system includes a front cavity, a rear cavity, and a damping component adapted to slow down an airflow from the rear sound cavity to enter a cavity inside the electronic device at a low flow rate and thereby weaken impact of the airflow on a housing of the electronic device, decrease amplitude, and dampen or alleviate housing vibration.

A loudspeaker assembly for a vehicle includes a loudspeaker mounted in the vehicle, the loudspeaker having a first side facing an interior of the vehicle and an opposed second side. The loudspeaker is configured to generate an acoustical signal having a front wave directed into the interior of the vehicle and a rear wave directed away from the interior of the vehicle. An acoustic coupler is disposed on the second side of the loudspeaker and extending toward an exterior of the vehicle, the acoustic coupler arranged to transmit the rear wave to the exterior of the vehicle such that the acoustical signal is audible in the interior of the vehicle and at the exterior of the vehicle.

According to an aspect of the disclosure, a loudspeaker includes an enclosure. The enclosure includes a first plurality of sidewalls. The loudspeaker further includes a horn. The horn is defined in part by the first plurality of sidewalls. The horn includes a second plurality of sidewalls that are coupled to the first plurality of sidewalls and that include a first sidewall and a second sidewall. The horn further includes a motorboard that includes a first opening arranged along a plane and a second opening arranged along the plane. The motorboard is coupled to the first sidewall and the second sidewall. The loudspeaker further includes an active driver arranged concentric to the first opening to transmit sound waves directly through the first opening, and a passive component arranged concentric to the second opening to transmit sound waves directly through the second opening.

The present disclosure relates to a speaker device including a core housing. The core housing may accommodate an earphone core. An absolute value of a difference between a first phase of a vibration of a housing panel of the core housing caused by the earphone core and a second phase of the housing back of the core housing caused by the earphone core may be less than 60 degrees when a frequency of each of the vibration of the housing panel and the vibration of the housing back is between 2000 Hz and 3000 Hz. A button may be disposed at a button hole on the circuit housing, and move relative to the button hole to generate a control signal for a control circuit to cause the earphone core to vibrate to generate a sound. An elastic pad may be disposed between the button and the button hole.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

An electronic device is provided. The electronic device includes: a housing at least partially surrounding a space between a front surface and a rear surface of the electronic device, and including a side structure through which a speaker hole is formed; a speaker configured to emit a sound signal through the speaker hole; a vibration motor structure provided adjacent the speaker, and including a plurality of side surfaces, wherein a motor ventilation hole is formed through a first side surface of the plurality of side surfaces; an enclosure provided in the housing, and surrounding at least a portion of the speaker and at least a portion of the vibration motor structure; a sound absorbing structure provided in the enclosure; and a protection structure provided in the enclosure, and overlapping at least a portion of the motor ventilation hole.

A loudspeaker arrangement for a seat within a motor vehicle utilizes one or more localized sound output ports for low frequency sound reproduction. A housing, such as an enclosure, substantially surrounds a loudspeaker. One or more audio transmission line channels acoustically interconnect the interior of the enclosure to one or more sound output ports. The enclosure is situated below, behind, or in some fixed location around or within a vehicle seat. The sound outputs ports are situated at or near a headrest such that the output ports are located substantially less than a wavelength of sound at the highest operating frequency from either ear of the seat's occupant. The acoustic response and resonances of a 1) rear enclosure, 2) a front vented enclosure, 3) a loudspeaker, and 4) an audio transmission path from the enclosure to one or more output ports are used to provide localized low frequency sound reproduction.

A loudspeaker system, having a good low-frequency response without a large box and effectively improving the efficiency of the loudspeaker system, so as to increase the output sound pressure level of the system, comprises a box and a plurality of loudspeakers arranged in the box and connected in parallel with each other, wherein each of the loudspeakers comprises a frame, a diaphragm arranged on the frame, and a voice coil for driving a vibration of the diaphragm; front surfaces of the diaphragms of the loudspeakers are arranged to face each other; a sound cavity is formed among the front surfaces of the diaphragms, and the sound cavity is in communication with the outside of the box; and each of the frames is located between a rear surface of its corresponding diaphragm and an inner wall of the box.

There is provided a headrest housing a dipole loudspeaker for producing sound at bass frequencies in a forward direction and in a rear direction, a response 180 degrees out of phase from respective front and rear resonating surfaces. The headrest includes a waveguide formation to isolate sound from travelling through the headrest between the front surface and the rear surface. The headrest also includes an attachment formation, and the attachment formation suspends the first frame of the dipole loudspeaker and acts as a secondary suspension system. By including waveguide formations, the sound from the front surface of the dipole speaker can be guided outside of the headrest, wherein the shortest path from the front surface to the back surface is extended to be around the outside of the headrest. Guiding the sound path to be external to the headrest, prevents internal sound guiding compressing the intended path length.

An apparatus includes a vibration member, a vibration apparatus disposed on a rear surface of the vibration member to vibrate the vibration member, a supporting member on a rear surface of the vibration apparatus, the supporting member including a first surface facing the vibration member and a second surface opposite to the first surface, a vibration signal cable disposed on the first surface or the second surface of the supporting member, and a conductive connection member electrically connecting the vibration apparatus to the vibration signal cable.
