A display device includes a double-sided display module. The double-sided display module includes first and second display modules arranged back to back and connectors. Each connector includes at least one first connection hole and at least one second connection hole. The first display module includes first connection portions. The second display module includes second connection portions; and positions of the connectors, the first connection portions and the second connection portions are in one-to-one correspondence; the first display module and the second display module are fixedly connected to the connectors through the first connection portions and the second connection portions; and each first connection portion is connected to a connector through one of a first connection hole and a second connection hole of the connector, and each second connection portion is connected to the connector through another of a first connection hole and a second connection hole of the connector.

A display assembly includes a display device, a first clamping plate and a second clamping plate. The display apparatus has at least one display area, and the first clamping plate and the second clamping plate are disposed on two opposite sides of the display device in a thickness direction thereof. At least one of the first clamping plate and the second clamping plate is located on at least one light-emitting side of the display device, and in a clamping plate located on a light-emitting side of the display device, at least a partial region of a portion covering an active area of the display device is in a transparent state. The display device includes a double-sided display module including a first display module and a second display module that are arranged back to back and an encapsulation housing configured to fix the first display module and the second display module.

The invention relates to a sound-equipped headrest comprising at least one woofer associated with an open rear part, comprising a rear grid and/or open cell or semi-open cell foam with a density of between 8 and 60 kg/m.sup.3, so that said at least one woofer is two-directional; and at least one mid-range/tweeter, associated with a closed rear part comprising a solid wall and/or a closed cell foam so that at least one mid-range/tweeter is mono-directional.

To make it possible to provide an acoustic device in a headrest device such that a standard of a shock is satisfied and the performance of the acoustic device can be efficiently exhibited. In the headrest device, a shock resistant surface is formed in a core material of a headrest main body, an opening is formed in the shock resistant surface, and a non-contact type acoustic microphone is disposed on the inner side of the opening.

A member-fastening structure permits three members to be fastened and fixed such that a first member and a second member holds a third member therebetween. The fastening of three members is accomplished with a meter visor that has a first through-hole formed therein. A speaker ring has a projecting part formed thereon which is inserted into the first through-hole. The projecting part has a second through-hole formed therein in a direction perpendicular to a projecting direction of the projecting part. A speaker grille is positioned on the meter visor, and the projecting part of the speaker ring is then caused to project downward through the first through-hole of the meter visor. A clip is inserted into the second through-hole of the projecting part projecting from an underside of the meter visor, and is engaged with the second through-hole of the projecting part and the underside of the meter visor.

A sound generating apparatus for vehicles may include a sound generator including a sound generating member configured to vibrate a vehicle interior material of a vehicle. The sound generating member may include a plurality of vibration generator spaced apart from one another, a first protection member at a first surface of the plurality of vibration generators, and a second protection member at a second surface opposite to the first surface of the plurality of vibration generators.

A motor vehicle hybrid panel assembly includes a body formed of a metallic sheet having multiple apertures created therein. At least one reinforcement member of a polymeric material is integrally connected to the body proximate to and surrounding at least two of the multiple apertures. At least one connecting member of the polymeric material is integrally connected to each of the at least one reinforcement member, and extends away from the at least two of the multiple apertures on the body. At least one joining member of the polymeric material is integrally connected to the at least one reinforcement member and integrally connected to the body.

A motor vehicle hybrid shelf assembly includes a metallic sheet body. A body shelf defines a plane having multiple apertures. Each of the apertures is at least partially surrounded by a peripheral flange created from a portion of the shelf extending away from the plane defined by the shelf. A first leg of the peripheral flange of each of the apertures is integrally connected to the shelf and is angularly oriented with respect to the shelf, and a second leg of the peripheral flange is angularly oriented with respect to the first leg. A reinforcement member of a polymeric material is integrally connected to at least the second leg of the peripheral flange. Multiple ribs formed of the polymeric material directly contact a surface of the body to stiffen the body. The ribs extend between successive peripheral flanges and integrally connect to the reinforcement member of the peripheral flanges.

A sound apparatus includes a sound generating module having a vibration member and a vibration apparatus configured at the vibration member, and an enclosure connected to the vibration member with an internal space therebetween. A portion of the vibration apparatus can be accommodated at the vibration member.
