An actuator, attached to a panel extending in a plane, includes a frame and a magnetic circuit assembly that includes a magnet and a voice coil, the magnet and voice coil being moveable relative to each other during operation of the actuator along an axis perpendicular to the panel's plane. The actuator further includes one or more suspension members attaching the frame to a first component of the magnetic circuit assembly. Each suspension member includes a segment attaching the suspension member to the frame at an attachment point and a first arm extending away from the attachment point to an end attached to the first component of the magnetic circuit assembly. During operation of the actuator the first arm of the one or more suspension members flex to accommodate axial displacements of the magnet relative to the voice coil.

An apparatus comprises a display panel configured to display an image, a vibration apparatus disposed at a rear surface of the display panel and configured to vibrate the display panel, a supporting member at the rear surface of the display panel, and a pad member between the vibration apparatus and the supporting member.

An apparatus includes a display panel displaying an image and a vibration apparatus disposed at a rear surface of the display panel to vibrate the display panel. The vibration apparatus may include a plurality of vibration generators overlapping one another. Accordingly, a sound may be generated based on a vibration of the display panel, and a sound having an enhanced sound pressure level characteristic may be output in a forward direction of the display panel.

A holographic sound field device. The device includes a frame, one or more transducers configured to produce a holographic sound field, a controller configured to generate and transmit vibration signals to the one or more transducers. The device can be used to transmit vibrations and/or sound into a person's body to promote healing, relaxation, regeneration, and/or meditation.

The present application provides an electronic device. After a display screen of the electronic device is attached to a screen frame, the display screen extends beyond the screen frame at at least two opposite edges and extends toward the second side of the display screen by taking the screen frame as an axis, and then the display screen is mounted by a mounting structure connected with the screen frame, so that the display screen is kept flat by a tensile force provided to the display screen via the mounting structure.

A sound producing package structure configured to produce sound includes a substrate, a sound producing component and a conductive adhesive layer. The sound producing component is disposed on the substrate, and the sound producing component is configured to generate an acoustic wave corresponding to an input audio signal. The conductive adhesive layer is disposed between the substrate and the sound producing component by a surface mount technology.

A display apparatus includes: a display panel configured to display an image; a supporting member on a rear surface of the display panel, wherein the supporting member is configured to support the display panel; at least one sound generating device on the rear surface of the display panel, wherein the at least one sound generating device is configured to vibrate the display panel to generate sound; and a partition between the rear surface of the display panel and an upper surface of the supporting member, the partition including a first material and a second material.

The present invention relates to a display device including a speaker using piezoelectric elements having an amplification effect in a low frequency range.

A flexible mobile device that appropriately adjusts the arrangement of a plurality of speakers provided in a mobile device based on the type of audio content includes the plurality of speakers; and a processor configured to analyze audio data; determine an angle between bending sides of the flexible electronic device including the plurality of speakers based on a result of analyzing the audio data; adjust the angle between the bending sides of the flexible electronic device to the determined angle; and output the audio data via the plurality of speakers included in the flexible electronic device in a state in which the bending sides of the flexible electronic device are adjusted to the determined angle.

A vibration device includes a plate-like glass vibrator and a plurality of exciters that are attached to the glass vibrator and configured to generate vibration according to an input electrical signal. An aspect ratio La/Lb of a length La of a longer side to a length Lb of a shorter side of a rectangle in which the glass vibrator is inscribed is 1.2 to 50. Provided that the number of the exciters is n and a minimum value of distance between the exciters is S.sub.min, a relational value α (α=S.sub.min−1)/La) is 0.2 to 0.8. In the case where the number n of exciters is 3 or larger, a value β(β=Sσ/S.sub.ave) obtained by dividing a standard deviation Sσ of distances by an average S.sub.ave of the distances between the exciters is 0 to 0.5.
