Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a voice bulletin board.

[0002]

[Prior art]

 Conventionally, as a voice bulletin board for outputting a sound from a bulletin board such as a poster or a signboard, for example, JP-A-10-97212 is cited. In this structure, a sensor, a voice circuit board storing voice, a speaker and the like are housed in a case to form an electronic message device, and the electronic message device is mounted on a bulletin board. Then, when a person approaches the signboard or touches the sensor, the sound stored in the sound circuit board is sent out from the speaker.

[0003]

[Problems to be solved by the invention]

 The voice bulletin board is preferably as thin as possible. Therefore, small speakers are also used. However, in the prior art, since the sound of the speaker is directly output from the hole provided in the case, a loud sound cannot be obtained with a small speaker. Therefore, in order to make the voice louder, a large speaker had to be used, and there was a problem that the electronic message device, that is, the voice bulletin board was inevitably thick. In addition, since the electronic message device is mounted on the bulletin board, if the content of the poster, signboard, etc. changes, it must be replaced with an electronic message device that stores the appropriate voice, which is time-consuming. Was.

[0004] An object of the present invention is to provide a voice bulletin board which can be made thinner and which can immediately respond to a change in the content of a notice.

[0005]

[Means for Solving the Problems]

 Claim 1 of the present invention for solving the above problem is a speaker having a flat or curved surface on which a poster or the like is attached on a surface thereof, and a speaker having a vibrating body portion attached to the back surface of the diaphragm. And an audio circuit disposed outside the diaphragm and connected to the speaker.

A second aspect of the present invention for solving the above-mentioned problem is that a vibrating plate made of a flat plate or a curved surface on which a poster or the like is pasted on a front surface, and a vibrating body portion of a speaker is mounted on the back surface of the vibrating plate. A plurality of voice bulletin boards, each of which includes a plurality of voice bulletin boards, and a plurality of voice bulletin boards having a back side facing inward to form a single voice bulletin board, wherein the speaker is disposed outside the diaphragm. It is characterized by being connected to.

[0007]

[Embodiment of the invention]

 A first embodiment of the present invention will be described with reference to FIG. The voice bulletin board 1 is composed of a flat diaphragm 2 and a speaker 3 attached to a back surface 2a of the diaphragm 2. A poster or the like is attached to the front surface 2b of the diaphragm 2 for use. Here, the material of the diaphragm 2 is not particularly limited as long as it vibrates. For example, foamed styrene, glass, plastic, thick letter, or the like is used. The speaker 3 has a vibrating body 3a attached to the diaphragm 2 with an adhesive, an adhesive tape, or the like.

[0008] Connection terminals 4 and 5 are attached to the left and right above the back surface 2a of the diaphragm 2, and one terminal of the speaker 3 is connected to one connection terminal 4 by a coating connection wire 6, and the speaker 3 Is connected to the other connection terminal 5 by a coating connection wire 7. One ends of the covered signal lines 8 and 9 are connected to the connection terminals 4 and 5, and the other ends of the covered signal lines 8 and 9 are connected to an audio circuit 10 disposed outside the diaphragm 2.

Therefore, a poster or the like is attached to the front surface 2 b of the diaphragm 2, and the covered signal lines 8 and 9 are also used as, for example, hanging strings, and the back surface 2 a side of the diaphragm 2 is used as a wall surface to serve as a hanging string. Hang 8 and 9 for use. The audio signal from the audio circuit 10 is supplied to the speaker 3 through the coated signal lines 8 and 9, the connection terminals 4 and 5, and the coated connection lines 6 and 7, and the vibrating body 3a of the speaker 3 vibrates. The sound vibration of the vibrating body 3a is transmitted to the diaphragm 2, and is output as a loud sound by the diaphragm 2.

As described above, since the sound of the speaker 3 is not output as it is, but is transmitted to the diaphragm 2 as a bulletin board and output, the loud sound can be obtained even with the small speaker 3. Thereby, the thickness of the voice bulletin board 1 can be reduced. Further, since the audio circuit 10 is provided outside the diaphragm 2 which is a bulletin board, when the poster changes, it can be easily replaced with the audio circuit 10 which stores the sound adapted to the poster.

A second embodiment of the present invention will be described with reference to FIGS. In the above-described embodiment, one surface 2b is used as a surface to which a poster or the like is attached, and sound is output from the surface 2b. In this embodiment, both sides 2b, 2b are used as a surface to which a poster or the like is attached, and sound is output from both sides 2b, 2b.

The voice bulletin board 1 shown in FIG. 2 includes two voice bulletin boards 1A and 1B. The voice bulletin boards 1A and 1B have the same configuration, and the configuration is shown in FIG. The two voice bulletin boards 1A and 1B shown in FIG. 3 are similar to the above-described embodiment, and the vibrating bodies 3a of the speakers 3A and 3B are respectively provided with an adhesive and an adhesive tape on the back surfaces 2a of the flat diaphragms 2A and 2B. And so on. The terminals of the speakers 3A and 3B are connected to the connection terminals 4A, 5A and 4B and 5B by coating connection lines 6A, 7A and 6B and 7B, and the connection terminals 4A, 5A and 4B and 5B have coating signal lines 8A, 9A and 8B and 9B are connected.

As shown in FIG. 2, the two voice bulletin boards 1A and 1B configured as shown in FIG. 3 are fixed to each other with an adhesive with the back surface 2a together and a spacer 11 interposed therebetween. The voice bulletin board 1 is used. With this configuration, in addition to obtaining the same effects as those of the above-described embodiment, a poster or the like can be attached to both sides 2b, 2b, and sound can be obtained from both sides 2b, 2b.

A third embodiment of the present invention will be described with reference to FIG. In the present embodiment, the four voice bulletin boards 1A and 1B shown in FIG. 3 are combined in a square, and the four sides 2b, 2b, 2b, 2b are used as a pasting surface of a poster or the like, and the four sides 2b, 2b, 2b, The voice is output from 2b. Even with such a configuration, the same effect as in the above embodiment can be obtained.

In each of the above embodiments, the case where the apparatus is used while suspended is described. However, it is needless to say that the apparatus may be installed in a stand. Also, the case where the poster or the like to be pasted is one-sided as shown in FIG. 1, two-sided as shown in FIG. 2, and four-sided as shown in FIG. 4, has been described as a triangular, three-sided, polyhedral or circular body. It may be formed. The diaphragms 2, 2A and 2B are formed in a flat plate shape, but may be formed in a curved surface.

[0016]

[Effect of the invention]

 According to the present invention, there is provided a diaphragm having a flat or curved surface on which a poster or the like is pasted on a surface thereof, a speaker having a vibrating portion of a speaker mounted on the back surface of the diaphragm, and a speaker disposed outside the diaphragm. Since it is composed of an audio circuit connected to the speaker, it is possible to reduce the thickness and to respond immediately to changes in the content of the notice.
