A loudspeaker comprises a first diaphragm, a second passive diaphragm, and a drive unit coupled to the first diaphragm. The drive unit is configured to drive the first diaphragm in a direction of excursion upon applying electrical energy to the drive unit. The second passive diaphragm is arranged opposing the first diaphragm. The second passive diaphragm is mainly driven by sound waves emitted from the first diaphragm.

A speaker device is provided. The speaker device includes a frame, and a vibration unit, a magnetic circuit unit, and air-permeable isolation member. The magnetic circuit unit includes a yoke fixed to the frame. The yoke and the frame are spaced to form a leakage port to enable leaking from a side surface of the speaker device. The sound-producing inner cavity communicates with the leakage port. The air-permeable isolation member completely covers the leakage port. The leakage port communicates with the outside through the leakage hole. Compared with the related art, the speaker device of the present disclosure has a yoke leakage structure, which can realize self-sealing and is conducive to assembling.

An apparatus can include a display member configured to display an image, a vibration apparatus disposed at a rear surface of the display member, a supporting frame disposed at a rear surface of the vibration apparatus, and an adhesive member disposed between the supporting frame and the rear surface of the display member. In addition, the adhesive member and/or supporting frame is spaced apart from the vibration apparatus, and the vibration apparatus is configured to vibrate in a direction toward the display member.

The present invention provides a speaker including: a frame, a vibration system and a magnetic circuit system. The vibration system includes a vibration diaphragm and a voice coil. The magnetic circuit system includes a magnetic part, and the voice coil is arranged around the magnetic part. The vibration system further includes an elastic plate with two branch elastic plates. The branch elastic plate includes a connection part, an extension part, an elastic arm and a fixed part. The surfaces of the connection part and the extension part facing the connection surface are recessed together to form a welding slot, and the lead wire is accommodated in the welding slot. The speaker provided by the present invention can not only effectively prevent the voice coil from swaying, but also reduce the number of parts to simplify the product structure.

A speaker device is provided. The speaker device includes a frame, a vibration unit and a magnetic circuit unit. The vibration unit and the magnetic circuit unit are fixed to the frame. The magnetic circuit unit is configured to drive the vibration unit to vibrate to produce sound. The magnetic circuit unit includes a yoke. The yoke and the frame are spaced to form a leakage port. The vibration unit includes a diaphragm, a voice coil, and an elastic support assembly. The auxiliary diaphragm has one end fixed to the frame and the other end connected to the voice coil. The auxiliary diaphragm is provided with multiple vents spaced and penetrating the auxiliary diaphragm. The present disclosure can increase the circulation of gases above and below the auxiliary diaphragm, so that a side leakage effect of the speaker device is improved, thereby improving acoustic performance of the speaker device.

An electromagnetic transducer includes a yoke, a first magnet, a second magnet, and a spacer. The yoke is disposed along a vertical axis. The first magnet is magnetically coupled to the yoke and has a polarization in a first orientation with respect to the vertical axis. The second magnet is magnetically coupled to the yoke and has a polarization in the first orientation with respect to the vertical axis. The spacer is disposed between the first magnet and the second magnet and is extended along the vertical axis.

An electronic device including a holder, a first buffer element, a second buffer element and a loudspeaker is provided. The holder includes a first section and a second section perpendicular to the first section. The first section and the second section are respectively provided with a first opening and a second opening. The first buffer element is disposed in the first opening of the first section. The second buffer element is disposed in the second opening of the second section. The loudspeaker is supported on the housing by the holder. The first buffer element is connected to the loudspeaker, and the second buffer element is connected to the housing.

Disclosed is a speaker assembly. The speaker of the present disclosure may include a first housing in which a first speaker is mounted; a second housing in which a second speaker is mounted, and which is adjacent to the first housing; and a plate which protrudes from the first housing toward the second housing, and to which the second housing is movably coupled, wherein a portion of the plate may be bent between the first housing and the second housing, when the second housing moves away from the first housing.

A micro-speaker includes a frame body, a diaphragm on the frame body, a magnetic structure and a voice coil in the frame body. An upper end of the voice coil is fixed to the diaphragm. The magnetic structure is arranged under the voice coil. A voice coil balancing system is provided in the frame body, which is composed of two symmetrically arranged dampers, which are respectively arranged under two ends of a long axis of the voice coil and fixed with glue. Each of the dampers is made of a flexible circuit board, including a first end, a second end and a cantilever connecting the first end and the second end. A ratio of a length L of the cantilever to a distribution distance D of the cantilever is between 2-15.

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.
