[Conventional technology]

FIG. 9 is a plan view of a passenger car equipped with a conventional vehicle-mounted speaker device disclosed in Japanese Unexamined Patent Publication No. 107702/1983. In the figure, 1 is the vehicle body, 2L, 2
R is the front seat arranged in parallel at the front of the vehicle body 1,
3 is the rear seat, 4L, 4R are the left and right doors, 5L,
5R is an all-band speaker fixed to the lower front of each of the left and right doors, 6 is a rear parcel, and 7L and 7R are all-band speakers fixed to the left and right upper end surfaces of rear parcel 6. It is. In the above example, the in-vehicle speaker device 5
Although the case where L, 5R, 7L, and 7R are installed in four locations inside the passenger car is shown, the in-vehicle speaker device 5 is installed only in the rear parcel 6 or only in the left and right doors.
In some cases, L, 5R, 7L, and 7R are provided.

[Problem that the invention attempts to solve]

In the conventional car speaker device as described above, each speaker 5L, 5R, 7L, 7
Since R is fixedly arranged, it is possible to move the speakers 5L, 5R, 7L, and 7R in any direction after fixing them, or to arrange the speakers 5L, 5R, 7L, and 7R in any direction.
It was impossible to change the orientation of L, 5R, 7L, and 7R. Therefore, the left and right speakers 5L, 5
Even if you try to play stereo with
There was a problem that the sound images of L and 7R were heard louder and the stereo reproduction effect was reduced.

In addition, if the speakers 5L and 5R are fixedly placed below and in front of the left and right doors 4L and 4R, the sound emitted from the speakers 5L and 5R will be reflected by the floor etc. inside the vehicle body 1, and the sound will be dispersed. There was a problem in that passengers could not get the sense of sound spreading due to the stereo effect, and often felt uncomfortable due to noise inside and outside the car.

This invention was made to solve these problems, and the purpose is to provide a vehicle-mounted speaker device whose position or angle can be adjusted so that the occupant can obtain the best stereo sound.

[Means to solve the problem]

The in-vehicle speaker device according to this invention has a pole hole provided corresponding to the pole material of the headrest, a threaded hole provided in the pole material inserted into the pole hole for supporting with a screw, and a screw hole provided for supporting the pole material with a screw. A support piece material having an elongated hole provided in the longitudinal direction at a position opposite to the hole, and a through hole inserted into the elongated hole of the support piece material and having an oval cross section and a through hole in the center through which a speaker mounting screw portion is inserted. a speaker positioning member consisting of a positioning part having a positioning part, a collar on a hollow disk provided at the lower part of the positioning part, and a speaker mounting screw part that is inserted through the through hole and the collar of the speaker positioning member. It is equipped with a screw.

[Effect]

A supporting piece having a pole hole provided corresponding to the pole material of the head rest and an elongated hole located opposite to the pole hole is supported by a screw on the pole material of the head rest, and the cross section inserted into the elongated hole is supported by a screw. A speaker positioning member having a through hole in the center part of the oval top and a hollow disk-like flange at the bottom is inserted into the elongated hole of the support piece, and is inserted through the through hole and the flange of the speaker positioning member. By fixing the mounting screw portion of the speaker with a screw through the support piece and the speaker support member, the speaker can be moved to a desired position and angle, and the occupant can obtain a stereo sound.

It has the same configuration as the speaker 20R, and is assembled in the same manner as the speaker 20R described above.

In the description of the above embodiment, the supporting piece materials 10R, 10
Although the L hole 11R is a circular hole, it is not limited to a circular hole, and the connection pole material 9
It is sufficient to form a hole with a cross-sectional shape of R, 9L or a shape corresponding to the dimensions thereof, and the supporting piece material 10
The dimensions and shape of the elongated holes 13R and 13L of R and 10L may be elongated holes corresponding to the size of the speakers 20R and 20L or the external dimensions of the mounting screws 22R. Furthermore, the hole 27R of the positioning member 23R can also have a hole diameter equal to the outer diameter of the mounting screw 22R of the speakers 20R, 20L. It goes without saying that the external dimensions of the speakers 20R and 20L can be formed into any shape and appearance corresponding to the appearance of the headrest 8.

FIG. 7 is a plan view of a passenger car in which the speaker device described in the above embodiment is installed.
0R is the speaker installed in the rear seat 3, 4
0L, 40R and 41L, 41R are speakers respectively provided on the front seats 2 arranged in parallel. In this way, the speakers 20R, 20L, 30R, each provided as a pair,
30L, 40R, 40L, 41R, and 41L are movable in various directions, and can be moved closer or further away from the passenger's ears.
It is possible to control the sound field according to the occupant's preference, such as by directing R, 40L, 41R, and 41L toward the windshield or the like and utilizing reflected sound.

FIG. 8 is an explanatory diagram showing another embodiment of this invention, in which the front seat 2 and the headrest 8f are
They are joined by a connecting pole material, and full-band speakers 50R and 50L are attached to the connecting pole material via supporting pieces 10R and 10L. In this case, the speakers 50R and 50L can be rotated 360 degrees around their mounting screws.
Furthermore, when the sound emission direction of the speakers 50R and 50L is directed toward the rear seat 3 side, the passenger 80 can listen to the stereo reproduction sound from the front.

[Effect of idea]

According to this invention, the pole material of the headrest is inserted into the pole hole provided on one side of the supporting piece material provided corresponding to the pole material and fixed with a screw, and the elongated hole provided on the other side of this supporting piece material. The directivity of the speaker can be adjusted by inserting the mounting screw part of the speaker through the through hole and collar of the speaker positioning member that slides into contact with the speaker, and fixing the speaker at a desired position and angle by screwing the mounting screw part. The sound field can be freely controlled by the occupant, and the disadvantages of suppressing the stereo effect caused by noise inside and outside the vehicle can be overcome.
