Description

  The present invention relates to an automobile seat provided with a seat acoustic system including a bone conduction sound system, and further relates to an automobile seat provided with a seat acoustic system constituted by a bone conduction sound system and an air conduction sound system. .

In automobiles, it can be combined with a bone-conducted sound system that incorporates a large speaker in the seat back and a bone-conducted sound system by arranging corresponding left and right small speakers on the left and right shoulders A bone beat sound sheet that is equipped with an air conduction sound system and that allows the occupant to hear the music is well known.
The large speaker is held by a mesh cushion and is housed in a box-shaped storage case that is suspended on its seat back frame by multiple coil springs and covered with a conductive cushion and seat back pad. Is called.
And, since this kind of automobile seat has a reaction force characteristic in which the reaction force becomes extremely high at the location of the large speaker, the mesh structure cushion and the seat back pad are thickened to ensure cushion performance.
However, since the seat back pad is made of urethane foam, the cushioning property is preferable. However, since the seat back pad absorbs sound and attenuates the vibration, the acoustic effect is impaired and the vibration transmission characteristic is deteriorated.
Also, since the sound hits the back of the occupant in an area approximately equivalent to the speaker diameter, the sensation area is limited, and the urethane foam absorbs the sound and impairs the sense of reality.

  The object of the present invention is to improve the sound and vibration conductivity by improving the sound and vibration conductivity, disperse the sound and vibration over a wider area than the outer shape of the speaker, and conduct sound throughout the back of the passenger. , You can feel the sound by conducting vibrations, without losing the sense of reality, and the seat back can be made thin, cushioning and breathability can be ensured, the sitting comfort is not impaired・ Providing seats.

  According to the present invention, a hole is opened at a predetermined position, and the resin suspension board is suspended from the seat back frame by a plurality of springs, and is fixed to the back surface of the resin suspension board in alignment with the hole. A bone conduction speaker attached to the surface, a flat plate-like conduction cushion supported on the surface of the resin suspension board, and superimposed on the surface of the conduction cushion and covering the seat back frame And a bone-conducted acoustic system including a seat back pad that is assembled to the seat back frame and forms a seat profile.

  In the present invention, the resin suspension board is used instead of the storage case of the conventional seat acoustic system, and the speaker is directly attached to the back surface of the resin suspension board so that the resin suspension board is utilized as a vibration generator. Sound, vibration conductivity is improved, the sound and vibration conduction effect is enhanced, sound and vibration are distributed and conducted over a wider area than the outer shape of the speaker, sound and vibration are spread throughout the back of the passenger Conducted, conducted to the bone, feel the sound, experience the sense of reality, the feeling of sound and vibration against the back is distributed without concentrating on the speaker area, improve the sitting comfort, and the seat back is thin In addition, cushioning and breathability are ensured, and improved sitting comfort is ensured.

A bone-conducted sound system opens a hole at a predetermined position, and a resin suspension board suspended from a seat back frame by a plurality of springs, and the resin suspension board aligned with the hole. A bone conduction speaker fixedly attached to the back surface, a flat plate-shaped conduction cushion supported on the surface of the resin suspension board, and a seat back A seat back pad that covers the frame and is assembled to the seat back frame and forms a seat profile.
Then, the resin suspension board is formed into a three-dimensional shape, and the conductive cushion is only subjected to extrusion molding, and the work of making the three-dimensional shape by hot pressing after the extrusion molding is omitted.
The speaker is directly attached to the back surface of the resin suspension board, and the resin suspension board is used as a vibration generator.

  Hereinafter, the automobile seat of the present invention will be described based on the specific examples specified and illustrated. FIGS. 1 to 3 are specific examples of the automobile seat of the present invention which is used for a driver seat of a passenger car. 10 and the driver seat 10 incorporates a seat cushion 11 incorporating a seat track and a headrest 13 to incorporate a seat acoustic system, and the seat cushion 11 with left and right reclining devices. It is assembled into a bone beat sound seat with a seat back 12 that is supported forward and angle-adjustable to the vehicle, and is installed on the passenger car floor with its seat track so that it can be adjusted back and forth, and to the driver while driving With the sheet sound system 14, the music is not lost Which is considered so that can be sensitive.

  The seat acoustic system 14 includes a bone conduction sound system 15 and an air conduction sound system 16, and the bone conduction sound system 15 includes a resin suspension board 23, a bone conduction speaker 26, and a net structure. The flat conductive cushion 27 and the seat back pad 22 are included, and the air conduction sound system 16 includes left and right air conduction speakers 32 and 32.

  In the bone conduction sound system 15, the resin suspension board 23 opens a plurality of holes 28, 28, 28, 28, 28 at predetermined positions, and a plurality of coil springs 29-29, 29. -29, 29-29 to the left and right frame sides 19, 20 of the seat back frame 17, and the left and right hooks 30, 30 to the suspension wire 21 on the frame top 18 side of the seat back frame 17, respectively. The bone conduction speaker 26 is fitted to the plurality of holes 28, 28, 28, 28, 28 and attached to the back surface 25 of the resin suspension board 23. Further, the conductive cushion 27 is superposed on the surface 24 of the resin suspension board 23 and supported. And, further, the seat back pad 22 is overlaid on the surface 31 of the conductive cushion 27 and is assembled to the seat back frame 17 over the seat back frame 17, and Form the seat-back outline.

The resin suspension board 23 is formed on the seat back 12 in a three-dimensional shape that determines the seating surface shape, that is, the shape of the backrest surface, and the conductive cushion 27 only needs to be extruded. The work of making a three-dimensional shape by hot pressing after extrusion molding is omitted.
The resin suspension board 23 functions as a vibration generator by directly screwing the bone conduction speaker 26 to the back surface 25 of the resin suspension board 23.

  The bone conduction speaker 26 is also screwed directly to the back surface 25 of the resin suspension board 23 in this manner, and also functions to conduct sound.

  In the air conduction sound system 16, the left and right air conduction speakers 32, 33 correspond to the left and right of the frame top 18 of the seat back frame 17 with the left and right speaker brackets 34, 35, respectively. And it is fixedly attached and supported.

  Therefore, in the driver seat 10 assembled in such a bone beat sound sheet, the resin suspension board 23 is used instead of the storage case of the conventional seat acoustic system, and the back surface 25 of the resin suspension board 23 is used. Since the resin suspension board 23 is utilized as a vibration generator by directly attaching the speaker 26 to the sound source, the sound and vibration conductivity is improved, and the sound and vibration conduction effect is enhanced, and the outer shape of the speaker 26 is improved. Sound and vibration are distributed and transmitted over a wide area, sound and vibration are transmitted to the entire area of the back of the occupant, sound is also transmitted to the bones, and a sense of realism is experienced, and a feeling of backrest of the sound and vibration is felt. Is distributed without concentrating on the speaker area, the seating comfort is improved, and the seat back 12 can be made thin and the Down resistance and breathability is ensured and the enhanced comfort is ensured.
