Description

[Detailed description of the invention] The present invention relates to the invention of a hanging and stationary vehicle-mounted speaker, which can be easily installed in a vehicle and can be deformed as appropriate.
Furthermore, the present invention aims to provide a speaker that can be freely installed in any of various vehicles.

Various attempts have been made to equip vehicles with speakers, but the speakers conventionally employed for this purpose are only set in a fixed state and do not have any variability.

For example, coupe, Tsuchibatsuku, light van (wagon)
Due to the shape and structure of the vehicle body, in many cases the speakers are installed in the rear of the vehicle interior with the speakers facing each other, so it is completely impossible to separate the stereo channels in the driver's seat or passenger seat in the case of a car stereo. .

Also, the stereo sound inside the vehicle is related to the number of people riding in the vehicle (once the speaker is installed, its position cannot be changed). The state of sound propagation changes due to the load on board, etc., and even if a speaker with excellent directivity can be considered, the mounting position will vary, so it is necessary to quickly respond to such conditions and always obtain a favorable listening relationship. It is extremely difficult to do so, and there are also disadvantages such as limited sound range.

The present invention was devised after repeated studies in view of the above-mentioned actual circumstances, and can be adapted to the changing conditions as described above, and is consistent with the quality of the car sound inside the vehicle. We succeeded in creating a new speaker that allows for flexible settings.

That is, to explain a specific embodiment of the present invention as shown in the attached drawings, an L-shaped speaker pipe 2 with a small speaker 1 attached to the bent end 2a is slid and moved so as to face both ends of the storage pipe 50. The speaker pipe 2 is assembled so that it can be rotated, and the speaker pipe 2 is equipped with a sound-absorbing material 4, and a small diameter duct pipe 3 is inserted into the storage pipe 5, and one end of the duct pipe 3 is inserted into the storage pipe 5. In addition, hook members 9 for locking to the top of the seat backrest are provided at both ends of the storage pipe 5, and a bass reflex hole is provided in the center of the hook member 9. 6, and furthermore, a connecting portion 14 for connecting an elbow pipe 8 or the like as shown in FIG. It is something.

Each of the pipes 2, 5, or 8 as described above is made of a synthetic resin material, and the hook member 9 is made of a gold plate or a synthetic resin material. As shown in FIGS. 2 and 3, the shape of the backrest 12 of the seat 11 can be quickly adjusted to provide a stable setting. A cord 10 is guided to the speaker 1 from a cord insertion hole 7 provided in the middle of the housing pipe 5.

Regarding the connection between the speaker pipe 2 and the storage pipe 5 as described above, a suitable backing material may be layered on the insertion end of the speaker pipe 2 and simply inserted, but as shown in FIG. A thread 2b having a relatively short range is formed at the charging end of the pipe 2, and this thread 2b is engaged with a thread 5b formed over a relatively long range on the inner surface of the storage pipe 5. Good too.

The duct pipe 3 as described above is generally about one third of the length of the speaker pipe 2, and as described above, the sound absorbing material 4 is layered on the inner surface of the speaker pipe 2. The purpose is to extract only the absorbed bass range, and the bass sound coming out of the speaker pipes 2 on both sides is collected in the storage pipe 5, and is extracted as a localized bass range through the bass reflex hole 6. has bottomed out.

In other words, the speaker pipes 2, 2 on both sides can be appropriately contracted with respect to the contraction pipe 5 as shown in Fig. 2.3, but no matter how they are contracted, the above-mentioned low The sound in the range is extracted from the bass reflex hole 6 (exactly the same effect relationship can be obtained).

The installation of the above-mentioned device according to the present invention to the seat is as shown in Figures 2 and 3, and when it is applied to only one of the separate seats, the speaker pipe 2° is attached as shown by the solid line in Figure 2. 2 is in a sufficiently compressed state, and the elbow pipe 8 can also be appropriately connected to set it in a stable state. Similarly, by extending the speaker pipes 2 and 2, a stable state can be set.
When applied to both l and l'l, shrink pipe 5
is both sea N1. It is certain that it will be located in the middle of H.

Further, when applied to the bench seat N1a, as shown in FIG. 3, it is applied to the driver's seat or the rear part of the rear seat, and a stable mounting relationship can be similarly formed in the form P2.

The above-mentioned installation state according to the present invention can be appropriately adopted for any vehicle type, and the relationship between them is summarized in FIG. 4, and as shown in FIG. Or it can be used on either the rear or in the driver's seat area for vehicles that carry luggage, as shown in Figure B.
For cars with a small rear par shelf, it is used as shown in Figure C.

The device of the present invention, which can be adopted without making holes in the seats or body of a luxury car, can be used freely as shown in the same plan, and can be used in cars where there is no installation, such as sports cars and coupes, or It can also be applied to open cars and cars with removable roofs, as shown in Figure 4 E and F.

Furthermore, the sound propagation state of the speaker according to the present invention equipped as described above is as shown in FIG. can.

As shown in FIG. 6, the conventional speakers 21 are provided on both sides of the rear seats of the vehicle body 20, so that the sound waves are reflected repeatedly, which is obviously undesirable to listen to.

According to the present invention as described above, the speaker can be set by freely deforming in response to the seat, the number of people in the car, or the loaded state of luggage. It is possible to change the relationship between the seats and match the usage conditions of the seats, and the hook member 9 allows the seats to be set without damaging them, and in some cases, it is also possible to set them in a suspended position. By using a cylindrical resin pipe, we have achieved a lightweight and highly safe product, and since it is a bass reflex type, it has a small speaker, %i
- It has the effect of enabling localized sound and large output, and is a highly effective idea in practical terms.
