According to an aspect of the disclosure, a loudspeaker includes an enclosure having a front sidewall that is disposed between a first acoustic opening and a second acoustic opening. The loudspeaker further includes a motorboard comprising a first opening arranged along a plane and a second opening arranged along the plane, an active driver, and a passive component. The active driver is arranged concentric to the first opening to transmit sound waves directly through the first opening toward the front sidewall. In addition, the passive component is arranged concentric to the second opening to transmit sound waves directly through the second opening toward the front sidewall.

The present invention provides for a woven mesh element for an electroacoustic driver enclosure, and to an electroacoustic driver enclosure including such an element, wherein the element includes a plurality of mesh layers, and wherein the plurality of layers includes a layer of Dutch weave mesh preferably including a layer of Dutch Twill weave mesh, and in particular wherein the element includes plural layers of cross woven wire mesh and a layer of Dutch weave wire mesh.

Disclosed is a sound-producing apparatus, including a vibration assembly and a magnetic circuit assembly, the vibration assembly includes a diaphragm which vibrates to generate sound waves, wherein, a middle region of the magnetic circuit assembly is hollowed out to form a volume expansion cavity penetrating through the magnetic circuit assembly, with a flexible deformation portion being provided in a region of the magnetic circuit assembly located in the volume expansion cavity; the flexible deformation portion covers a port of the volume expansion cavity or separates the volume expansion cavity into two regions that are isolated from each other; the flexible deformation portion is disposed facing the diaphragm, and can vibrate as a function of air pressure.

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.

A display device includes: a display panel; a bracket disposed under the display panel; a first vibration generator disposed under the display panel, where the first vibration generator outputs sound by vibrating the display panel in a thickness direction of the display panel; and a second vibration generator disposed under the bracket, where the second vibration generator outputs horizontal vibrations by vibrating the bracket in a horizontal direction perpendicular to the thickness direction.

A loudspeaker is provided that includes an outer tubular section, an inner tubular section at least partially disposed within the outer tubular section, a driver disposed in the inner tubular section at an angle offset from a cross-sectional plane of the inner tubular section, a sound deflector disposed at a first end of the outer tubular section, and a void defined collectively by a space between a first end of the inner tubular section within the outer tubular section and the sound deflector, and a space between an outer portion of the inner tubular section and an inner portion of the outer tubular section. The sound produced by the driver passes through the void via the space between the first end of the inner tubular section within the outer tubular section and the sound deflector, and then via the space between the outer portion of the inner tubular section and the inner portion of the outer tubular section.

Bass reflex type loudspeaker enclosure comprising a cabinet, a loudspeaker and a first vent. The acoustic loudspeaker enclosure further comprises a second vent and an internal heat sink which is located inside the cabinet and intended to be thermally coupled to an electrical component in order to dissipate, inside the cabinet, heat produced by the electrical component, the first vent, the second vent and the internal heat sink being positioned so that an air flow which flows through the first vent, the second vent and into the cabinet moves the heat produced by the electrical component out of the cabinet.

A thin double-sided vibrating speaker includes a magnet member, a first vibration assembly and a second vibration assembly; the magnet member includes a main magnetic plate, a first magnetic path unit, a second magnetic path unit and side magnetic path units, the first magnetic path unit is disposed on one surface of the main magnetic plate, the second magnetic path unit is disposed on another surface of the main magnetic plate, the side magnetic path units are disposed on the main magnetic plate and correspond to two sides of the first magnetic path unit, the first vibration assembly is disposed on one surface of the magnet member, and the second vibration assembly is disposed on another surface of the magnet member. Accordingly, in addition to achieving the requirement of thinning, the thin double-sided vibrating speaker of the present disclosure also has the effect of vibration reduction and two-way sounding.

The flat speaker according to an embodiment of the present invention includes a voice coil plate, a diaphragm for generating sound according to vertical vibration of the voice coil plate, a damper contacting a lower end surface of the voice coil plate, and a yoke having a first yoke having a “-” shape in cross section and a second yoke having an “L” shape in cross section and the first and second yokes are disposed to face to each other to form asymmetry.
