[Problems to be Solved by the Invention] However, in the conventional advertising panel with an acoustic function, the dynamic speaker 22 is used as the speaker, but the dynamic speaker has a large thickness due to its characteristics, and it is difficult to obtain sufficient volume. In order to do this, it is necessary to use a large-sized device, which poses the problem of increased weight.

Furthermore, in order to transmit the sound (air vibration) generated by the dynamic speaker 22 to the front of the panel 21, it is necessary to provide an air hole 23 in the panel 21, which complicates the manufacturing process and reduces the cost of advertising etc. There is a problem in that the design of the system is restricted.

The present invention solves the above problems, and aims to provide an advertising panel with an acoustic function that is thin and lightweight, does not require air holes for transmitting sound, and has a high degree of freedom in design. purpose.

[Means to solve the problem]

In order to achieve the above object, the advertising panel with acoustic function of the present invention includes an acoustic driver unit formed by housing a piezoelectric acoustic driver formed by bonding a piezoelectric element to a metal plate in a foamed resin case. , an advertising medium for displaying product names, product photos, etc., characterized in that it is attached to a panel made of a material that vibrates acoustically when driven by the acoustic driver unit.

[0007]

[Function] The acoustic driver unit is thin, small and lightweight, and by attaching it to a panel, a thin and lightweight advertising panel with an acoustic function can be obtained. In addition, the acoustic driver unit vibrates the panel to function as an acoustic diaphragm, and the acoustic driver unit and panel work together as a speaker function, so it does not work like a conventional advertising panel with an acoustic function. , there is no need to provide air holes in the panel to transmit sound from dynamic speakers, increasing flexibility in advertising design.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view showing an advertising panel with an acoustic function according to an embodiment of the present invention, and FIG. 2 is a front view thereof. As shown in these figures, the advertising panel of this example is
Three acoustic driver units 2 are attached with adhesive to the back side of a panel 1 made of thick paperboard with letters (for example, a product name) and a picture of an animal drawn on one side (the front side) and cut into the shape of an animal. It is formed by gluing and pasting and connecting the acoustic driver unit 2 to an acoustic device 3 such as a stereo amplifier.

FIGS. 3 and 4 are an exploded perspective view and a sectional view showing the structure of the acoustic driver unit 2. FIG. As shown in FIG. 5, this acoustic driver unit 2 includes a piezoelectric element (formed by providing electrode films on both sides of a piezoelectric ceramic plate) 4
It is formed by housing a piezoelectric acoustic driver 6 in a bimorph structure in a case 7 so that it can vibrate. The case 7 is formed from an upper sealing plate 7a and a lower sealing plate 7b. The upper and lower sealing plates 7a and 7b are made of foamed resin (for example, modified polystyrene foam), and have inner recesses 8.
Protrusions 8a and 8b are provided in the central part of. The piezoelectric acoustic driver 6 is held in the case 7 by the protrusions 8a and 8b so as to be able to vibrate. Note that lead wires 9 are connected to the piezoelectric element 4 and metal plate 5 of the piezoelectric acoustic driver 6 (FIG. 5). This piezoelectric acoustic driver 6 is housed in a recess 8 of a case 7, and its center portion is a protrusion 8a inside the recess 8.
, 8b, and held so as to vibrate.

As mentioned above, the acoustic driver unit 2 is attached to the back side of the panel 1, and the acoustic driver unit 2 is attached to the back side of the panel 1.
In an advertising panel formed by connecting an audio device 3 such as a stereo amplifier, the acoustic driver unit 2 is integrated with the panel 1 to constitute a speaker (piezoelectric speaker), and the acoustic driver unit 2 is integrated with the panel 1 to form a speaker (piezoelectric speaker). By connecting the lead wire 9 to the output terminal of the acoustic device 3 and applying a predetermined acoustic signal, the acoustic driver unit 2 mechanically vibrates, which is transmitted to the panel 1 and causes the panel 1 to vibrate (acoustic vibration). generates a sound. As a result, the content of the advertisement drawn on the front side of the panel 1 appeals to the viewer's visual sense and exhibits an advertising effect, and the generated sound also appeals to the auditory sense, resulting in a great advertising effect.

Furthermore, the piezoelectric acoustic driver 6 used in the above embodiment has, for example, a thickness of about 0.2 mm and a diameter of about 6 mm.
0 to 80mm (diameter varies depending on the sound range from bass to treble), weight = approximately 8g, thin and lightweight, and this is Case 7
The acoustic driver unit 2 housed in the speaker is also much smaller and lighter than a dynamic speaker (approximately 5 mm to 15 mm thick).
mm, diameter of approximately 100 mm, and weight of approximately 15 to 20 g), making the advertising panel significantly thinner and lighter. Therefore, restrictions on the installation position when hanging or standing up on the ground are alleviated, making it possible to use it for a wide variety of purposes.

[0012] In the above embodiment, a case was explained in which cardboard was used as the constituent material of the panel 1, but the material of the panel 1 is not limited to this. It is possible to use various materials that can function as a board, such as a wood rack board or a foamed resin board.

[0013] Furthermore, in the above embodiment, a case was explained in which the panel 1 in the shape of an animal was used, but there is no particular restriction on the shape of the panel 1, and panels of various shapes such as circular and rectangular can be used. . Furthermore, the panel does not necessarily have to be flat; it is also possible to use a curved panel.

[0014] In the above embodiment, three acoustic driver units 2 are attached to the panel 1, but there is no particular restriction on the number of acoustic driver units 2. The number can be selected arbitrarily.

Further, in the above embodiment, a case will be described in which a piezoelectric acoustic driver 6 having a bimorph structure in which piezoelectric elements 4 are bonded to both sides of a metal plate 5 is used as the piezoelectric acoustic driver 6 constituting the acoustic driver unit 2. However, the piezoelectric acoustic driver is not limited to one having a bimorph structure. For example, a piezoelectric acoustic driver (not shown) in which one piezoelectric element is bonded to one surface of a metal plate may be used.

[0016]

[Effect of the invention] The advertising panel with acoustic function of this invention has the following features:
The acoustic driver unit, which is formed by housing a piezoelectric acoustic driver inside a foamed resin case, is attached to the panel.
Since this acoustic driver unit is much smaller and lighter than conventional dynamic speakers, the entire advertising panel can be made significantly thinner and lighter. and,
As a result, installation constraints are significantly reduced,
It becomes possible to use it widely for various purposes. In addition, since there is no need for air holes and there is a high degree of freedom in design, the front side of the panel can be designed freely, and the content of the advertisement drawn on it appeals to the viewer's visual sense, creating a great advertising effect. The sound generated by this also appeals to the sense of hearing, further improving advertising effectiveness.
