The present disclosure relates to a display device for generating sound by directly vibrating a display panel thereof, which includes a display panel connected to a surface of the display panel and configured to display an image; and a sound generating actuator, which is fixed to a support structure of the display panel and attached to the display panel to directly vibrate the display panel. In the display device, the progressing direction of the sound coincides with the image output direction in the display device. Therefore, sound localization or sound output characteristics of the display device or set apparatus can be improved, and a separate speaker is not required, the mechanism of the set apparatus can be easily designed, and a thickness thereof can be easily reduced.

The present invention provides a method for making a speaker vibrating member, including: impregnating a fiber cloth with a resin solution for at least one time; removing the fiber cloth from the resin solution, and impregnating the fiber cloth with a water-based rubber solution for at least one time; drying the fiber cloth; forming at least one speaker vibrating member shaped portion on a dried fiber cloth; and cutting the at least one speaker vibrating member shaped portion off from the dried fiber cloth to acquire the speaker vibrating member. In such a way, the fiber cloth may be prevented from sticking with the mold during the formation step due to the protection provided by the release layer. In addition, the speaker vibrating member manufactured by the method has a higher flexibility and a remarkable fatigue resistance; consequently, the sound quality of the speaker may be enhanced.

The micro-speaker includes a hollow frame, a diaphragm, a voice coil, an elastic damping piece, and a magnetic circuit assembly. The hollow frame includes a hollow portion, a top surface, and a bottom surface. The diaphragm includes a central portion and an outer peripheral portion surrounding the central portion. The voice coil is coaxially held in the hollow portion. The voice coil includes a top edge fixedly connected to the central portion and a bottom edge. The elastic damping piece includes an outer fixing member connected to the hollow frame, an inner fixing member connected to the voice coil, and an elastic piece body connected between the outer fixing member and the inner fixing member. The magnetic circuit assembly is held in the hollow portion and is in the voice coil but not in contact with the voice coil.

Embodiments of a speaker spider for a loudspeaker or transducer are provided. The speaker spider may include a textile material formed of a woven pattern with a plurality of concentric corrugations. The weaving pattern and/or dimensions of the speaker spider may substantially homogenize and/or reduce stress on the speaker spiders during operation of the speaker. The weaving pattern of the textile material of the speaker spider may include a pattern formed of a plurality of substantially concentric circular shapes, and/or a pattern including threads tangential to the central opening.

A damper and a speaker apparatus includes the damper, which suppresses damage to an oscillatory system from an excessive input signal, enabling an efficiency increase of the speaker apparatus. As a damper has a planar surface, undue deformation of the oscillatory system due to an excessive input signal is suppressed, and damage to the oscillatory system can be suppressed. Furthermore, since the deformation of a corrugation portion by a normal input signal is hardly prevented, a reduction in sound pressure of the speaker apparatus with respect to an input signal is suppressed, enabling an increase in efficiency. Furthermore, the planar surface is extended at a height in a thickness direction different from that of an attachment portion. Thus, rising portions are deformed when a voice coil bobbin is oscillated, enabling suppression of rupture of the damper in the vicinity of a boundary between the planar surface and the attachment portion.

An inertial exciter for use with an acoustic radiator, the inertial exciter comprising: a magnet assembly including a magnet unit configured to provide a magnetic field in an air gap, wherein the air gap extends around a movement axis of the inertial exciter; a coil assembly including: an attachment portion configured to provide an attachment between the coil assembly and the acoustic radiator; a voice coil; a voice coil former which extends from the attachment portion into the air gap.

A speaker assembly, and a display device including the same are provided. The speaker assembly according to an aspect of the present disclosure includes: a pair of magnets facing each other; a bobbin disposed between the pair of magnets and formed in a shape of a plate that extends long; a coil formed on at least one surface of the bobbin; a diaphragm fixed to one side of the bobbin, and extending in a direction intersecting a longitudinal direction of the bobbin; a frame disposed between the pair of magnets and the diaphragm; and a speaker edge disposed between the frame and the diaphragm, having one end fixed to the frame and the other end fixed to the diaphragm, and being convexly curved toward the bobbin.

A vibrating unit includes a diaphragm and a bobbin, and a voice coil is secured to the bobbin. A detecting unit includes a moving magnet and a magnetic sensor. The magnetic sensor is disposed in a space surrounded by the bobbin, whereas the moving magnet is secured to an outer surface of the bobbin. Therefore, even when the moving magnet and a damper member move backward significantly, the magnetic sensor is prevented from being hit by the moving magnet and the damper member.

An actuator module includes a base plate extending in a plane, a voice coil connected to the base plate, and a magnet assembly that includes a back side facing the base plate and a front side facing away from the base plate. The magnet assembly includes a base layer and sidewalls defining a cup and an inner element including a center magnet mounted within the cup. The sidewalls include a first and second pair of sidewalls. The actuator module includes a rigid frame attached to the base plate, the rigid frame including four stubs. The actuator module also includes a plurality of springs suspending the magnet assembly relative to the frame and base plate, the plurality of springs including a first spring attached to the frame at a first pair of the four stubs and a second spring attached to the frame at a second pair of the four stubs.
