The present invention relates to a chair including a multi-channel sound system, and more particularly, to a chair including a multi-channel sound system capable of providing rich sound effects to a user who sits in the chair through sounds output from a plurality of channels.

A headrest having a bone conduction two-way sound transmission system is provided. The system has a bone conduction speaker and bone conduction microphone mounted on the same printed circuit board. Additional components of the bone conduction two-way sound transmission system, such as a control unit, contact sensors or proximity sensors, and an antenna for communication with external electronic devices can be mounted on the same printed circuit board. Assembling the components of the system is easy and subsequent assembling the two-way sound transmission system inside the headrest is simpler, faster, and less subject to human errors, thus increasing the quality of the final product while keeping the manufacturing costs low.

An audio system for a seat headrest includes N speaker(s), each configured to be integrated into a seat headrest, N being an integer greater than or equal to 1, and an audio processing device including an electronic transmission channel connected to the speaker(s) and configured to transmit at least one audio stream via the speaker(s). The audio system comprises P microphone(s), each configured to be integrated into the headrest, P being an integer greater than or equal to 1. The audio processing device further includes an electronic receiving channel connected to the microphone(s) and configured to receive at least one sound signal via the P microphone(s).

Various implementations include seats and related loudspeakers. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly. The loudspeaker assembly includes at least one driver for generating an acoustic output; and an acoustic exit fixed in the seat backrest portion and angled to provide the acoustic output to a location below a nominal ear position of an occupant of the seat, wherein a firing angle of the at least one driver provides the acoustic output to achieve a consistent frequency response across a range of positions deviating from the nominal ear position.

The present invention relates to a member for a chair for implementing a multi-channel sound system and a chair including the member, and more particularly, to a member for a chair, the member having a plurality of speakers installed therein to implement a multi-channel sound system and installed in a chair to provide sound environments having a sense of space and a three-dimensional effect to a user who sits in the chair, and a chair including the member.

The present invention relates to a chair equipped with a multi-channel sound system, and more particularly, to a chair equipped with a multi-channel sound system, which is capable of providing a sense of space and a three-dimensional effect for a user who sits in the chair through sounds output from a plurality of channels and allows the user to adjust orientation directions and orientation angles of speakers by himself or herself and realize a sound environment optimized for the user.

An audio device for a vehicle includes a loudspeaker system having a plurality of loudspeakers, which are arranged spatially such that they enable a three-dimensional listening experience in a vehicle interior. The audio device also includes a control unit which is coupled to the loudspeaker system and which is configured to control at least one loudspeaker of the loudspeaker system in order to reproduce a position-specific warning signal which is linked to a specific position. For reproducing the position-specific warning signal, the control unit controls only the loudspeaker or those loudspeakers of the loudspeaker system which is/are closest to the specific position.

Provided is a multifunctional base, which includes a first cover, having a first connecting edge made of flexible material and extended along a periphery of the first cover, the first connecting edge is configured to sealingly connect the multifunctional base with an object; and a second cover, the second cover is connected with first cover to define a receiving space. A bag is also provided.

A dual-zone automotive multimedia system may include a first infotainment device associated with a front zone of a vehicle, at least one second infotainment device associated with a rear zone of a vehicle, wherein the at least one second infotainment device includes a directional loudspeaker arranged facing the rear zone of the vehicle, and a processor programmed to transmit audio signals to the first and second infotainment devices to create sound at each of the front and rear zones, wherein the audio signal transmitted to the directional loudspeaker relates to playback at the rear zone.

The invention relates, inter alia, to an equipment part for a vehicle, including a base, at least one first foam layer and a covering, wherein the equipment part is provided with at least one audio cushion device which has at least one loudspeaker device having at least one loudspeaker, wherein each loudspeaker has a sound outlet. The first foam layer has an opening which extends along a center axis of the sound outlet such that the sound can continue through the opening in the direction toward the covering. A sound-permeable carrier layer covers the opening and in the direction of the sound propagation behind the carrier layer a second foam layer is arranged which engages over the opening.
