Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker system, and more particularly to a speaker cabinet mounting structure.

[0002]

2. Description of the Related Art In a conventional speaker system for bass reproduction, when a speaker cabinet becomes large in order to produce a bass, the place where the speaker cabinet is installed is limited to under a desk or on the floor. For example, speakers for personal computers are
In many cases, satellite speakers are placed on the desk and subwoofers are placed under the desk. Also, JP-A-9-25287
The one proposed in No. 5 has a speaker placed on the back of the chair back.

[0003]

However, when the speaker is arranged under the above-mentioned conventional desk, the speaker may be squeezed by the foot, and there is a problem that the speaker becomes an obstacle. Also, if you place a speaker on the floor in the corner of the room,
There was a problem that the connection cable from the personal computer to the speaker became long. Also, when the viewer tries to obtain a sufficient volume, the power consumption of the amplifier increases, and further,
There is a problem that sound leaks to the surroundings.

Even for general household use, if the subwoofer is arranged at a position distant from the viewer to obtain a sufficient low-frequency feeling, the power consumption of the amplifier increases. In the example in which the speaker is placed on the back of the chair, it is difficult to install a subwoofer having a large volume and a speaker capable of providing a sufficiently low range. That is, if a large speaker cabinet is attached to the backrest, the chair may fall to the backrest side. In addition, a small speaker cabinet cannot reproduce sufficient bass, and the reproduced sound has directivity. Then, sound is emitted in the direction opposite to the direction of the viewer sitting in the chair, which adversely affects the surroundings.

The present invention has been made in view of the above points, and an object of the present invention is to be easily attached at a position close to a viewer sitting on a chair and to be an obstacle to the viewer. There is no speaker system.

[0006]

In the speaker system of the present invention, the speaker cabinet is fastened to the chair pedestal so that the chair pedestal is sandwiched between the speaker cabinet and the fixture.

In the speaker system of the present invention, a mounting recess is provided in the speaker cabinet, and the speaker cabinet is fastened to the chair pedestal such that the pedestal of the chair is sandwiched between the recess and the mounting tool.

In the speaker system, the speaker cabinet mounting recess is provided on the rear surface of the speaker cabinet, and the speaker diaphragm is mounted so as to be oriented in the horizontal direction.

In the speaker system, the speaker cabinet mounting recess is provided on the side surface of the speaker cabinet, and the speaker diaphragm is mounted so as to face downward or upward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A speaker system according to an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing a speaker system according to a first embodiment of the present invention. The speaker cabinet 1 shown in the figure is attached to the chair 3 so as to be located below the seating surface of the chair 3. A method of mounting the speaker cabinet 1 will be described with reference to FIGS. 2 and 4.

A semi-cylindrical surface-shaped recess 1a is formed on the rear surface of the speaker cabinet 1 which faces the surface on which the speaker 2 is mounted.
Is provided, and the semi-cylindrical surface-shaped recess 1a and the fixture 5 are provided.
The fixture 5 is fastened to the speaker cabinet 1 with the screws 6 so as to sandwich the pedestal 4 of the chair 3 with.

As shown in FIG. 2, a receiving portion 7 is attached to the side portion of the seating surface of the chair 3, and is connected to a connecting unit 8 attached to the speaker cabinet 1 by a connecting cord 9. The connection unit 8 includes a battery and a speaker driving amplifier. A signal from a personal computer or the like placed on a desk is transmitted to a receiver 7 by a wireless device such as Bluetooth or IR (Infrared), and further amplified by a connection unit 8 to drive a speaker in a speaker cabinet 1. As shown in FIG. 3, the elongated hole 5a into which the screw 6 of the fixture 5 is inserted extends in the horizontal direction, and the position of the screw 6 can be adjusted in the direction of the arrow shown.

FIG. 5 (a) shows the case where the pedestal 4, the inner surface of the fixture 5 and the radius of the semi-cylindrical surface-shaped recess 1a are the same, and the pedestal 4 is formed by the fixture 5 and the semi-cylindrical surface-shaped recess 1a. The speaker cabinet 1 can be firmly fixed by directly sandwiching.

FIG. 5B shows the case where the radius of the pedestal 4 is smaller than the radii of the inner surface of the fitting 5 and the semi-cylindrical surface-shaped recess 1a. The fixture 5 is fastened with the spacer 10 interposed therebetween. By thus preparing the spacer 10, the speaker cabinet of this embodiment can be fixed to chairs of various sizes.

FIG. 6 shows the positional relationship between the viewer and the speaker cabinet 1 in this embodiment. The satellite speaker 11 is placed on the desk, and the speaker from the speaker cabinet 1 attached to the chair 3 is used. The sound is emitted forward between the legs of the viewer.

Since this speaker emits a low tone, the sound is circulated and the viewer can fully listen to the sound from the speaker of the speaker cabinet 1. Then, the speaker cabinet 1 of the large bass speaker does not get in the way.

FIG. 7 shows a speaker system according to a second embodiment of the present invention. In this example, the speaker cabinet 12 is provided with a semi-cylindrical surface-shaped recess having the same shape as that of the first embodiment on the side surface perpendicular to the surface on which the speaker 2 is attached, and the diaphragm of the speaker 2 is shown in FIG. ), The speaker cabinet 12 is attached to the pedestal 4 of the chair 3 in a state in which the speaker cabinet 12 faces downward, or in a state in which the speaker cabinet 12 faces upward as shown in FIG.

The sound is radiated downward in the example shown in FIG. 7A, and is emitted upward in the example shown in FIG. Can be heard enough.

If a semi-cylindrical surface-shaped recess is provided in the speaker cabinet as shown in the embodiment and this part is fastened to the cylindrical pedestal of the chair, a large speaker cabinet can be stably and firmly fixed. it can.

[0020]

According to the speaker system of the present invention,
The positional relationship between the viewer and the speaker is always constant, and a stable sound field can be obtained.

Further, since the speaker cabinet is below the seating surface of the chair, it does not interfere, and since the speaker and the viewer are close to each other, a sufficient low pitch can be obtained even at a low volume.

Further, since the speaker can be arranged close to the audio signal reproducing device, wireless transmission can be used.
