Description

  The present invention relates to a building panel with a speaker function.

  Conventionally, as a panel with a speaker function, for example, a panel shown in Patent Document 1 is known. According to this Patent Document 1, a through-hole is formed in a plate-shaped substrate, a back plate is attached to the back surface of the substrate, and a vibrator (vibrator) is accommodated in the through-hole. An acoustic plate is disposed so as to cover the through hole. In this acoustic plate, only the peripheral portion is bonded to the front surface of the substrate, and the entire acoustic plate is vibrated by vibrating the vibrator to propagate the sound.

Japanese Utility Model Publication No. 6-44226

  By the way, if the acoustic plate is bonded to the front surface of the substrate as described above, a difference in level occurs between the front surface of the substrate and the front surface of the acoustic plate, resulting in poor appearance.

  Moreover, a through hole is formed in the substrate, and the back plate is bonded to the back surface of the substrate, and the vibrator is housed in the through hole, and the acoustic plate is bonded so as to cover the through hole. Therefore, it is very time-consuming and may increase the manufacturing cost.

  Further, since such an acoustic plate has only a peripheral portion bonded to the substrate as described above, the vibration propagates to an unnecessary range as a vibration region. For example, a plurality of vibrators can be connected to one acoustic plate. When covered with a plate, there is a problem that vibrations from a plurality of vibrators interfere with each other.

  The present invention has been made in view of the above-described conventional problems, and the object of the present invention is to reduce the work man-hours while making the front of the panel look good, and to reduce the sound generated by the vibrator. An object of the present invention is to provide a building panel with a speaker function capable of suppressing vibration propagation to an unnecessary range as a vibration region while making the vibration region necessary for propagation easy to vibrate.

  In order to solve the above problems, the present invention has the following configuration.

That is, in the invention according to claim 1, a plurality of storage recesses 2 that are spaced in the longitudinal direction of the building panel 1 that is formed in a rectangular shape whose front surface is a decorative surface and are countersunk from the back surface. And the bottom of the storage recess 2 is defined as a thin portion 4. A vibration exciter 3 that is entirely contained within the thickness of the building panel 1 is provided in the thin-walled portion 4 in the housing recess 2. Further, a main groove 9 extending in the longitudinal direction of the building panel 1 and opening to both end faces of the building panel 1 and one end communicating with the main groove 9 and the other end being a storage recess are formed on the back of the building panel 1. A plurality of sub-grooves 10 communicating with the place 2 were provided.

  By having comprised in this way, even if it is a case where the vibrator 4 is provided in the building panel 1, the trace which provided the vibrator on the makeup | decoration surface does not appear at all, and it shall be good-looking. it can. Further, since it is only necessary to form a storage recess 2 by spotting the building panel 1 and store the vibrator 3 in the storage recess 2, the number of work steps can be reduced. Moreover, since the portion other than the thin portion 4 on the building panel 1 is thickened, the propagation of vibration to other ranges can be suppressed while making the thin portion 4 serving as the vibration region easy to vibrate. it can.

Moreover, when attaching the back surface of the building panel 1 to an attachment such as a base, the vibrator 3 can be prevented from interfering with the attachment.

  According to the present invention, even in a case where a vibrator is installed in a building panel, it is possible to make the appearance of the vibrator without any appearance on the decorative surface, and to improve the appearance. The manufacturing cost can be reduced by reducing the number of man-hours, and the propagation of vibration to other ranges can be suppressed while the vibration region of the vibrator is easily vibrated.

It is a disassembled perspective view of one Embodiment of this invention. It is a side view same as the above. It is a perspective view of other embodiment. It is a side view same as the above.

  The present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is an exploded perspective view of a building panel with a speaker function as an example of this embodiment. The building panel with a speaker function is attached to a building frame, a base plate (hereinafter referred to as a base), and is used as a building panel such as a ceiling material or a wall material.

  This building panel with a speaker function is formed in a rectangular shape (rectangular shape in the illustrated example), and is provided by mounting the building panel 1 attached to the foundation of the building and a spot facing on the back of the building panel 1. A storage recess 2 and a vibrator 3 installed in the storage recess 2 are provided.

  The building panel 1 of the present embodiment is made of MDF (Medium-Density Fiberboard), and the front surface is a decorative surface.

  A storage recess that is substantially centered in the short direction of the building panel 1 that is formed in a rectangular shape and is lined up in the same direction as the longitudinal direction (that is, near both ends in the longitudinal direction of the building panel 1). 2 is formed. The storage recess 2 has a circular shape in plan view, and is configured to be countersunk from the back of the building panel 1 and leave a part in the thickness direction of the building panel 1 as described above. That is, a thin portion 4 is formed on the bottom surface of the storage recess 2, and this thin portion 4 is a vibration region in which vibration by the vibrator 3 is easy to propagate (for example, for the building of this embodiment) The thickness of the panel 1 is 20 to 25 mm, and the thickness of the thin portion 4 is 1.5 to 2 mm). Since such a thin part 4 is thinner than other parts in the building panel 1, vibrations by the vibrator 3 are easily propagated, while parts other than the thin part 4 are thin parts 4. Therefore, the vibration by the vibrator 3 is difficult to propagate.

  In addition, as for the panel 1 for construction, the part in which the storage recess 2 is not formed occupies most, and the intensity | strength is raised.

  One vibrator 3 is attached to each thin portion 4 in each storage recess 2. More specifically, each vibrator 3 is attached by being attached to the center of the back surface of the thin portion 4, and is housed in the storage recess 2 without contacting the inner peripheral surface (side surface) in the storage recess 2. And each vibrator 3 in this embodiment is accommodated in the storage recess 2 in the state which a part of vibrator 3 protruded back rather than the panel 1 for construction, as shown in FIG.

  Each of the vibrators 3 is connected to a sound source device such as an audio amplifier (not shown) via a wiring 7 (see FIG. 3). Each vibrator 3 vibrates based on the signal output from the sound source device, thereby vibrating the thin portion 4 which is a vibration region provided in a part on the front side of the building panel 1 to make the sound forward. To emit.

  The building panel with a speaker function of the present embodiment described above has a flat decorative surface on the front surface of the building panel 1, and no traces of the storage recesses 2 are formed from the decorative surface. Even if a decorative sheet for construction (not shown) is pasted, unevenness does not occur, and the appearance can be improved. In addition, since the housing recess 2 is formed by carrying out spot facing from the back of the building panel 1 as described above, and the vibration exciter 3 has only to be installed in the housing recess 2, the number of work steps is reduced. I'm sorry. Of course, the decorative surface which is the front surface of the building panel 1 may be exposed without sticking the decorative sheet for building on the front surface of the building panel 1 as described above.

  Further, the building panel with a speaker function according to the present embodiment is configured such that the thin portion 4 serving as the vibration region is thin and the other portions are thick, so that the vibration by the vibrator 3 can easily propagate through the vibration region. However, it is possible to make it difficult for the vibration by the vibrator 3 to propagate to other portions. In other words, even when a plurality of vibrators 3 are provided on a single building panel 1 as in this embodiment, vibrations from the vibrators 3 are prevented from interfering with each other. be able to. Thereby, if the vibrator 3 is arrange | positioned at each both ends of the building panel with a speaker function of one sheet and it is made to sound each different, it is also possible to comprise a stereo speaker.

  In addition, one end of each building panel with a speaker function is given a signal in the high frequency band at one end, and a signal in the middle / low frequency band is given at the other end. It is also possible to construct a 2-way type speaker if it is pronounced.

  Furthermore, the building panel with a speaker function according to the present embodiment is mainly composed of a thick portion where the storage recess 2 is not provided, and can be used as a building panel having high strength.

  Next, another embodiment will be described with reference to FIG. In addition, since this embodiment is mostly the same as embodiment shown in FIG. 1, in the same part, the same code | symbol is attached | subjected and description is abbreviate | omitted and it mainly demonstrates a different part.

  The building panel with a speaker function shown in FIGS. 3 and 4 accommodates the entire vibrator 3 within the thickness of the building panel 1 so that the vibrator 3 is completely housed in the housing recess 2. It is configured to be.

  In the building panel 1 of the present embodiment, a wiring housing groove 8 communicating with each housing recess 2 is formed on the rear surface of the building panel 1. The wiring storage groove 8 includes a main groove 9 extending in the longitudinal direction of the building panel 1 and a plurality of sub-grooves 10 extending in the short direction of the building panel 1.

  Both ends of the main groove 9 are open to reach the end face in the longitudinal direction of the building panel 1. The sub-groove 10 has one end communicating with the main groove 9 and the other end communicating with the storage recess 2. As a result, each storage recess 2 communicates with the outside of the building panel 1 via the wiring storage groove 8.

  Each of the vibrators 3 of the building panel with a speaker function configured as described above is housed in the housing recess 2 so as to be within the thickness of the building panel 1, and therefore is rearward from the building panel 1. Does not protrude into Therefore, when the building panel with speaker function is attached to the ground, when the building panel 1 is attached to the front surface of the ground, the vibrator 3 does not interfere with the ground and the workability is good.

  Moreover, since the wiring 7 connected to each vibrator 3 can be accommodated in the wiring accommodation groove | channel 8 as shown in FIG. 3, the construction property of the building panel with a speaker function can further be improved. Moreover, it is not necessary to form a space for housing the wiring 7 behind the building panel 1, and the degree of freedom in construction increases.

  In addition, although the panel for construction with a speaker function of each embodiment mentioned above is provided with two vibrators 3, it may be provided with one or three or more vibrators 3. Shall. Further, the position, shape, and size of the storage recess in which the vibrator 3 is disposed can be appropriately changed according to the sound to be output. Moreover, the material of the building panel 1 is not particularly limited.
