EXAMPLE An example will be described with reference to FIGS. 1 and 2. Figure 1 shows an in-vehicle sensory acoustic device 1 installed on a car seat 2.
FIG. 2 is a perspective view showing the in-vehicle sensory acoustic device 1, a rubber band 3 for locking the in-vehicle sensory acoustic device 1 to the seat 2, and a hook 4. The in-vehicle sensory acoustic device 1 includes a vibration unit 11, a diaphragm 12, and a cushioning material covering the periphery thereof. The vibration unit 11 forms a magnetic air gap using a yoke with magnetic poles, and arranges a voice coil in this air gap. The structure is configured so that mechanical vibration is obtained by the magnetic interference effect generated between the magnetic force generated by the magnetic pole and the magnetic force of the magnetic pole. The diaphragm 12 is attached to the vibration output side of the vibration unit 11 and outputs vibration to a wider range. Further, the periphery of the vibration unit 11 and the vibration plate 12 is covered with a cushioning material to prevent vibration from being suppressed.

[0011] Vehicle-mounted sensory acoustic device 1 configured as described above
The outer shape of the seat 2 is such that it can be installed in a space 23 formed at the intersection of the seat 21 and the backrest 22 of the seat 2. That is, the vibration output surface 13 of the in-vehicle sensory acoustic device 1
is formed with a curve approximately equal to the curve extending from the backrest part 22 to the seat part 21, and is formed to provide a good fit to the waist area of the person sitting on the seat 2. Also,
The rear surface 14 side is formed into a C-shape or V-shape so that it can be inserted into the space 23, and therefore, the overall shape of the in-vehicle sensory acoustic device 1 is formed into a triangular prism or a D-shape in cross section. .

As a means for attaching and fixing the in-vehicle sensory acoustic device 1 configured as described above to the space 23 of the seat 2, an L-shaped hook 4 is attached to one end of the rubber band 3.
The hook 4 is connected to the seat 2 in a continuous manner with the space 23.
It is locked to the back side 25 of the seat part 21 through the gap 24 leading to the back side of the seat part 21. Further, the other end of the rubber band 3 is locked to locking tools 5 provided on both side surfaces 15 of the in-vehicle sensory acoustic device 1 . The traction force of the rubber band 3 at this time of locking presses the back surface 14 of the in-vehicle sensory acoustic device 1 against the seat portion 21 and the backrest portion 22 that form the space 23, and the in-vehicle sensory acoustic device 1 is moved to the seat 2. It is installed and fixed in the space 23. At this time, a traction force is applied to the rubber band 3 to the extent that the cushioning material in the in-vehicle sensory acoustic device 1 is not crushed.

[0013] Furthermore, as a means for separating the in-vehicle sensory acoustic device 1 that has been fixed in the space 23 from the space 23 when the backrest portion 22 is tilted forward, the in-vehicle sensory acoustic device 1 is removed from the space 23. A hard and slippery member (for example, synthetic leather, a resin material with a certain degree of hardness) is attached to at least the upper portion of the back surface 14 of the back surface 14, or is integrally formed therewith. In addition, when integrally formed, it is more effective to wrap the outer periphery of the cushioning material covering the vibration unit 11 and the diaphragm 12, and to form the entire exterior member with a slippery material to improve the design effect. . With this configuration, the in-vehicle sensory acoustic device 1 can
It can be detached against the pulling force of the rubber band 3.

Next, based on the side views shown in FIGS. 3 to 5 in which the in-vehicle acoustic acoustic device 1 is installed, when the backrest 22 is tilted forward, the in-vehicle acoustic acoustic device 1 separates from the space 23. The operation will be explained. When the back rest 22 is tilted forward as shown in FIG. 4 from the state where the in-vehicle sensory acoustic device 1 is mounted and fixed in the space 23 as shown in FIG. The pressing force at this time presses the back surface 14 of the in-vehicle sensory acoustic device 1 in the forward direction. Due to this pressing force, the rubber band 3 is stretched, and therefore, the in-vehicle sensory acoustic device 1, which has been installed and fixed in the space 23, stands up while moving forward using its lower side as support, and furthermore, as shown in FIG.
When the backrest 22 falls forward as shown in FIG. At this time, by forming at least the upper portion of the back surface 14 of the in-vehicle sensory acoustic device 1 with a slippery member as described above, the series of operations described above can be performed smoothly. Furthermore, when the backrest 22 is returned from the state shown in FIG. 5 to the original state shown in FIG. It is mounted and fixed again into the space 23 of.

[0015]

Effects of the Invention As explained above, in the seat mounting structure of the in-vehicle sensory acoustic device of the present invention, when the in-vehicle sensory acoustic device is attached to the seat, the hook provided at one end of the rubber band can be attached to the seat. All you have to do is pass it through the gap formed at the intersection of the seat and back of the seat to the back side and lock it, and then lock the other end to the in-vehicle sensory sound system. There is no need for any special processing, and anyone can easily and quickly attach and fix the device. Furthermore, when the other end of the rubber band is locked to the in-vehicle sonic device, the traction force exerted by the pulling motion applied to the rubber band ensures that the in-vehicle sonic device is securely attached to the seat. Therefore, even when the car suddenly stops, there is no risk of falling out of the seat. Furthermore, there is no risk of the wearing position shifting when you get up from your seat, eliminating the hassle of having to adjust the wearing position every time you sit down. On the other hand, when removing a fixed in-vehicle sensory acoustic device from the seat, it is only necessary to release the locking state described above, and there is no need for any complicated removal work, and anyone can easily and quickly remove it. can.

[0016] Also, a hook for securing to the back side of the seat,
Since it is configured to be locked to the back of the seat, even when the backrest is tilted backwards, the hook does not interfere with its operation and can maintain its locked state. On the other hand, when the backrest is tilted forward, the rubber band stretches due to the pressure applied to the in-vehicle sensory acoustic device that occurs when the backrest is tilted forward, and the rubber band is therefore secured. The in-vehicle sensory acoustic device can be moved forward using its underside as support and tilted forward, allowing it to be removed from the fixed mounting position, which can lead to accidents in which it gets caught between the seat and the backrest and gets crushed. can be prevented. In this way, since the in-vehicle sensory acoustic device is detached from the fixed mounting position and tilted forward, there is no obstacle to the forward tilting movement of the backrest. Furthermore, since at least the upper part of the back of the in-vehicle acoustic acoustic device is formed of a hard and slippery member, when the above-mentioned backrest is tilted forward, the upper portion of the in-vehicle acoustic acoustic device will sink into the backrest. It is possible to prevent the disengagement operation from becoming impossible. That is, in response to the forward tilting motion of the backrest, the upper part of the in-vehicle sensory acoustic device slides on the surface of the backrest. It is in a state where it is pushed forward by the surface, pushed out from the fixed mounting position, tilted forward, and can be removed from the space in which it is mounted and fixed. Furthermore, when the backrest is returned to its original position, the pressure exerted by the backrest is naturally released, so the in-vehicle sensory acoustic device can be pulled back to the mounting and fixed position by the traction force of the rubber band.
