The loudspeaker may comprise at least one electroacoustic transducer, a processor in communication with the at least one electroacoustic transducer, and an exterior surface comprising a capacitive touch user interface that allows a user to control operation of the loudspeaker. The exterior surface acts a dielectric for the capacitive touch user interface. The loudspeaker may comprise a wireless transceiver circuit for receiving and transmitting wireless communication signals via a wireless network. The wireless transceiver circuit may receive wirelessly audio content from streaming audio content servers that are connected to the Internet. The capacitive touch user interface comprises a plurality of capacitive sense electrodes.

The present disclosure relates to a vibration device and a sound device and a vehicle device including the same. A vibration device can include a vibration means and an adhesive member located at a surface of the vibration means. A modulus of the vibration means can be equal to a modulus of the adhesive member, or can be greater than the modulus of the adhesive member.

A loudspeaker comprising a frame (1), a cone paper (2) and a magnetic structure, characterized in that the cone paper (2) has a body (21) at its edge which, in a side section view of the loudspeaker, has a Y-structure forming an upper arm and a lower arm, each extending from the edge of the body (21), wherein an upper edge (22) is attached to the top of the upper arm and a lower edge (23) is attached to the underside of the lower arm; and wherein the upper edge (22) and the lower edge (23) project upwards and downwards respectively and form a symmetrical structure in the side view.

A speaker diaphragm includes a base material including a resin matrix including a thermoplastic resin as a main component, and fibers dispersed within the resin matrix. The fibers include a plurality of loss regions where the fibers are locally bent and broken, or a plurality of loss regions having a diameter 5% to 50% larger than an average diameter of the fibers

Disclosed is a multi-cone loudspeaker, including a cone assembly. The cone assembly includes a central cone and a plurality of outer cones successively arranged in a circumferential direction of the central cone. The central cone is driven by a central driving mechanism to vibrate and sound, each of the plurality of outer cones is driven by one of outer driving mechanism to vibrate and sound. The central driving mechanism includes a central voice coil connected to the central cone, and a central magnetic driving system for driving the central voice coil, and each of the plurality of outer driving mechanism includes an outer voice coil connected to one of the plurality of outer cones, an outer damper sleeved on the outer voice coil, and an outer magnetic driving system for driving the outer voice coil.

A loudspeaker assembly includes: a chassis; a loudspeaker, including a drive unit and a diaphragm. The diaphragm includes a body portion and inner and outer suspension portions, wherein the body portion extends between the inner and outer suspension portions. The drive unit moves the body portion along a movement axis. The body portion has a front face facing forwards and a rear face facing rearwards parallel to the movement axis. The outer suspension portion is integral with the body portion, and is attached to the chassis at a first attachment location such that the body portion is suspended from the chassis. The inner suspension portion is integral with the body portion, and is attached to the chassis at a second attachment location such that the body portion is suspended from the chassis. The first and second attachment locations have separate first and second positions along the axis, respectively.

To improve a sound characteristic and a sound pressure characteristic in a low-pitched sound band region.SOLUTION: A vibration apparatus may include a vibration element and an adhesive member at a rear surface of the vibration element. A modulus of the vibration element may be equal to a modulus of the adhesive member or may be greater than the modulus of the adhesive member.SELECTED DRAWING: Figure 1
