A car seat includes an air outlet located in a seat upper portion (a portion provided above a seat cushion and including a seat back and a headrest) to let out air therethrough; an air inlet located in the seat upper portion to draw in air therethrough; at least one fan configured to produce a current of air flowing from the air outlet toward the air inlet at a front side of the seat upper portion; and a scenting device configured to scent air to be forced out through the air outlet. The air outlet and the air inlet are located in such positions that at least part of the headrest is positioned between the air outlet and the air inlet in a direction from the air outlet toward the air inlet as viewed from a front side.

Seats that include sound cancelation systems are described. An example vehicle bench seat has a first backrest, a first speaker, a second backrest, a second speaker, a central portion, and a seat base. The first speaker is disposed within the first backrest and the second speaker is disposed within the second backrest. Each of the first and second speakers emit primary sound waves and secondary sound waves. The secondary sound waves of the first speaker are 180 degrees out of phase with the primary sound waves of the first speaker and the secondary sound waves of the second speaker are 180 degrees out of phase with the primary sound waves of the second speaker. The central portion includes channels that direct the secondary sound waves emitted by the first and second speakers into the vehicle cabin to cancel undesired primary sound waves.

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 including: 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 an 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, wherein the angle of the at least one driver is configured to be adjusted in response to a recline angle of the seat reaching a threshold.

In at least one embodiment, a vehicle apparatus is provided. The apparatus includes a core, a nose, a first loudspeaker, and a first loudspeaker housing. The core is positioned within a headrest for a seat of a vehicle. The nose attaches to the core and is positioned within the headrest. The first loudspeaker is positioned on the nose for providing an audio signal from the headrest. The first loudspeaker housing receives the first loudspeaker and is positioned on the nose. The first loudspeaker housing extends along a first outer edge of the core to decrease an overall length of the core and the nose along a first axis in the vehicle.

A loudspeaker arrangement comprises a frame including at least two mounting fixtures and a connecting element. The connecting element connects the at least two mounting fixtures to each other. The loudspeaker arrangement further comprises at least two loudspeakers. Each of the at least two loudspeakers is arranged in a different one of the at least two mounting fixtures. The loudspeaker arrangement further comprises an amplifier configured to amplify audio signals to be reproduced by the at least two loudspeakers. The amplifier is mechanically coupled to the connecting element between the at least two mounting fixtures.

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 neck support module for a headrest device of a vehicle seat comprises a frame and at least one inflatable pouch fixed to the frame.
