Hereinafter, a planar stationary closed speaker according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3 attached hereto.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a flat fixed sealing loudspeaker according to one embodiment of the present invention; FIG. Fig. 2 is a plan view of the flat fixed hermetic speaker shown in Fig. 1. Fig. 3 is a cross-sectional view of the flat, stationary sealed speaker shown in Fig.

1 to 3, the flat fixed type closed speaker according to one embodiment of the present invention includes a speaker unit 10, a case 20, a fastening member 30, and a packing member 40 .

The speaker unit 10 is composed of at least one speaker, and reproduces a voice signal output from the amplifier to convert the sound. As an example of such a speaker unit 10, the speaker unit 10 may be composed of a dynamic speaker such as a tweeter, a midrange (squawker), and a base (woofer). However, in the present invention, the speaker unit 10 is not limited to the above-described configuration.

The case 20 includes an inner joint 21, a receiving cylinder 22, a flexible member 23, and a coupling bolt 24.

The inner coupling body 21 is formed with a coupling hole 21a to which the speaker unit 10 is coupled and in which the sound of the speaker unit 10 is transmitted. In this case, the speaker unit 10 transmits sound The region is joined to the engaging hole 21a so as to face the outer region of the hole and is seated on the inner joint body 21. [ The inner joint body 21 is formed with a reverberation hole 21b spaced apart from the periphery of the engaging hole 21a so that the sound generated in the speaker unit 10 is discharged through the receiving cylinder 22. In this case, The hole 21b may further include a duct 21c protruding to the inside of the receiving cylinder 22 so that sound can be reproduced more smoothly. Further, the inner joint body 21 is further formed with a hole into which a coupling bolt 24 described later can be inserted.

The receiving cylinder 22 has a cylindrical shape in which an opening is formed on one side. In this case, the inner cylinder 21 is disposed in the opening portion of the receiving cylinder 22, and the speaker unit 10 is accommodated in the inner portion thereof. In this case, the receiving cylinder 22 is further provided with a screw-engaging hole 22a through which the engaging bolt 24 can be screwed.

The flexible member 23 is disposed between the inner coupling body 21 and a region where the receiving cylinder 22 is in close contact. This flexible member 23 is made of a high-molecular-soft-resin material such as silicone or rubber so that vibration of the speaker unit 10 coupled with the inner joint body 21 is not transmitted to the receiving cylinder 22, , So that the receiving cylinder 22 is prevented from ringing due to vibration.

The coupling bolt 24 is screwed to the threaded engagement hole 22a of the receiving cylinder 22 in the body by connecting the inner coupling body 21, the receiving cylinder 22 and the flexible member 23, The coupling body 21, the receiving cylinder 22 and the flexible member 23 are fixed.

The fastening member 30 is provided with the wall unit 1 and the speaker unit 10 in a state in which the case 20 is in close contact with the wall unit 1 so that the front face of the speaker unit 10 faces the wall unit 1. [ Respectively. Such a fastening member 30 may be made of a member such as a piece, as shown in the figure. Needless to say, the fastening member 30 may be modified to have a configuration such as a bonding material or a double-sided tape. In this case, the receiving cylinder 22 of the case 20 is extended to the outside of the receiving cylinder 22 for easy coupling with the fastening member 30, and a hole through which the fastening member 30 can be inserted The bracket 22d formed can be further configured.

The packing member 40 is formed of a flexible polymeric resin material such as rubber or silicone and is coupled to the receiving cylinder 22 along the outer surface of the upper surface of the receiving cylinder 22 of the case 20, It is possible to seal the portion where the wall portion 1 abuts against the receiving cylinder 22 of the case 20 when it is coupled by the fastening member 30 in tight contact with the wall portion 1. [ The packing member 40 prevents vibrations generated during the movement of the speaker unit 10 from being transmitted through the case 20 and the sound generated from the speaker unit 10 is transmitted to the outside of the case 20 of the case 20 As shown in FIG.

The flat fixed type closed speaker according to one embodiment of the present invention having the above-described configuration is fixedly used by the fastening member 30 in a state where the case 20 is in close contact with the wall part 1.

Here, the wall portion 1 may be a structure such as a thin plate, a glass door or a frame inside the automobile.

The flat fixed type closed speaker is fixed in a state in which it is in tight contact with the wall part 1 so that sound generated from the speaker unit 10 does not leak out to the outside of the case 20. When the sound is reproduced by the speaker unit 10, So that the reproduced sound is transmitted through the wall part 1 and reproduced.

In this case, the flat fixed type closed speaker according to an embodiment of the present invention prevents sound leaks to the outside of the case 20 by the packing member 40, thereby reducing the echo of the sound and clearly improving the sound quality.

The flat fixed type closed speaker according to one embodiment of the present invention is characterized in that a flexible member 23 is provided between the inner coupling body 21 and the receiving cylinder 22 so that vibration generated in the speaker unit 10 is transmitted to the receiving cylinder 22 So that the reverberation due to the vibration is prevented from occurring in the case 20, so that the sound quality can be clearly improved.

In addition, as described above, the planar stationary sealed speaker according to one embodiment of the present invention is such that the inner joint body 21 is tightly coupled to the opening of the receiving cylinder 22, As shown, is inserted in the inner space of the receiving cylinder 22. Therefore, the speaker unit 10 of the inner joint body 21 is disposed at a distance from the wall portion 1. The speaker unit 10 is disposed at a distance from the wall unit 1 so that the vibration of the speaker unit 10 is not transmitted to the wall unit 1 when the speaker unit 10 is driven, Only the sound other than the vibration can be transmitted through the wall portion 1 so that clear sound quality can be reproduced from the wall portion 1. [

Further, in the flat fixed type sealed speaker according to the embodiment of the present invention, the vibration isolating space 22e is further formed on the upper surface where the opening of the receiving cylinder 22 is formed. In this case, the vibration isolation space 22e is formed along the upper outer surface of the receiving cylinder 22 on the outer side. The vibration isolating space 22e is formed in the receiving cylindrical body 22 so that the inner joined body 21 does not touch the receiving cylindrical body 22 so that the vibration generated in the inner hollow body 21 is not transmitted to the receiving cylindrical body 22 So that the sound transmitted through the wall portion 1 is reproduced more clearly and the sound due to the sounding of the receiving cylinder 22 is generated .

In addition, the flat fixed type closed speaker according to one embodiment of the present invention is formed by protruding the bracket 22d outwardly of the receiving cylinder 22. The bracket 22d is formed with a hole into which the coupling member 30 can be inserted so that the flat fixed hermetic speaker according to one embodiment of the present invention can be easily attached to the wall portion 1 .

In this case, the flat fixed type sealed speaker according to one embodiment of the present invention may further include a cover 50. The cover 50 is coupled to the outside of the bracket 22d, and the bracket 22d and the fastening member 30 ) Of the user. The cover 50 visually blocks the fastening member 30 when the wall-mounted unit 1 is tightly coupled with the flat fixed-type closed speaker according to an embodiment of the present invention, so that the design is not deteriorated .
