Description

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

  For example, as shown in Patent Document 1, a speaker may be installed on a part of a ceiling of a room.

  By the way, since this kind of speaker does not originally constitute the ceiling of the building, it can be seen at a glance that the speaker is provided on the ceiling, and the room has no sense of unity.

  In the speaker of Patent Document 1, the peripheral portion of a diaphragm provided with a transducer is supported by a frame, and a step is formed between the frame and the diaphragm. For this reason, it looks bad and it can be easily recognized that the speaker is provided with a diaphragm on the inner side of the frame. In this respect, the room is not unified.

In addition, when this speaker is attached, the workability is poor, for example, the transducer protruding to the back side of the diaphragm may interfere with other members. Further, the diaphragm of this speaker is supported only by the frame at the periphery, and the strength of the member constituting the ceiling is low.

  The present invention has been made in view of the above-described conventional problems, and can be used in the same manner as a general building panel, and can also be used as a speaker, and has an appearance and workability. It is an object to provide a building panel with an excellent speaker function.

  In order to solve the above-described problem, the building panel with a speaker function according to claim 1 is provided with a housing hole 5 that opens to the front surface of the substrate 1, and an opening edge of the front end portion 5b of the housing hole 5 from the rear portion 5a. Is expanded to form a step 4, and the diaphragm 2 is disposed at the front end 5b of the storage hole 5 formed in the step shape so as to close the opening of the storage hole 5, and the front surface of the diaphragm 2 is The substrate 3 is flush with the front surface of the substrate 1, and the vibrator 3 is provided at the center of the rear surface of the diaphragm 2.

  Further, it is preferable to form a wiring housing groove 8 communicating with the housing hole 5 in the substrate 1.

  Moreover, it is preferable to arrange the vibrator 3 within the thickness of the substrate 1.

  The diaphragm 2 is preferably detachably attached to the substrate 1 from the front side of the substrate 1.

  In the first aspect, since the main body is constituted by the substrate in the same manner as a building panel that does not have a general speaker function, it can be used as a building panel having high strength. Further, the vibrator can vibrate the sound generating portion of the diaphragm that constitutes part of the ceiling surface and part of the wall surface together with the front surface of the substrate to emit sound, and can also be used as a speaker.

  Further, since the front surface of the diaphragm is flush with the front surface of the substrate, the appearance is good. In addition, since no step is formed between the front surface of the diaphragm and the front surface of the substrate, the appearance is almost the same as a general building panel. Further, the vibrator can be housed in the housing hole, and in the case of a building panel with a speaker function, the vibrator can be prevented from interfering with other members, and workability is good.

  Moreover, in Claim 2, the wiring connected to a vibrator can be accommodated in a wiring accommodation groove | channel, and the construction property of the building panel with a speaker function can further be improved. Further, it is not necessary to form a space for storing the wiring behind the substrate, and the degree of freedom in construction increases.

  According to the third aspect of the present invention, since the vibration exciter can be disposed within the thickness of the substrate, the vibration exciter is less likely to interfere with other members when the substrate is attached to the front surface of the base.

  Further, in claim 4, after the installation of the building panel with a speaker function, the diaphragm can be removed and attached together with the vibrator from the indoor side of the building panel with the speaker function. There is no need to remove it, and maintenance of the diaphragm and the vibrator can be easily performed.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

  The building panel with a speaker function of an example of this embodiment shown in FIG. 1 is attached to a building's crosspiece or base plate (hereinafter simply referred to as a base) and used as a building panel such as a ceiling material or a wall material. It is what is done. In addition, below, the indoor side in the installation state of the building panel with a speaker function is demonstrated as a front side.

  The building panel with a speaker function is formed in a rectangular shape (rectangular shape in the illustrated example), the substrate 1 attached to the base of the building, a plurality of diaphragms 2 provided on the front side of the substrate 1, and the rear surface of the diaphragm 2 And a vibration exciter 3 that vibrates the diaphragm 2.

  The substrate 1 is made of a wood material and is thicker than the diaphragm 2.

  Storage holes 5 that open to the front side of the substrate 1 are formed on both side portions of the substrate 1 formed in a rectangular shape in the longitudinal direction. Each storage hole 5 is a hole penetrating in the thickness direction (front-rear direction) of the substrate 1.

  Each storage hole 5 is formed of a hole in which the opening edge of the front end portion 5b is enlarged more than the rear portion 5a to form a step 4. In the illustrated example, the rear portion 5a is formed of a circular hole, and the front end portion 5b is formed of a hole having a larger diameter than the rear portion 5a.

  The inner peripheral surface of the rear portion 5a and the inner peripheral surface of the front end portion 5b are connected via a step 4 that is annular when viewed from the front. In the substrate 1, the portion where the storage holes 5 are not formed occupies most of the substrate 1, and the strength is increased.

  A diaphragm 2 is disposed at the front end 5b of each storage hole 5 formed in a step shape so as to close the storage hole 5, and a rear portion 5a is provided with a load provided on the rear surface of each diaphragm 2. A vibrator 3 is arranged.

  Each diaphragm 2 is formed in a circular shape, and its diameter and thickness are substantially the same as the inner diameter and depth of the front end portion 5b. Each diaphragm 2 is made of a material that is more elastic than the substrate 1 so as to be easily vibrated by the vibrator 3. Specifically, the diaphragm 2 is made of foamed polypropylene.

  The vibrator 3 is provided at the center of each diaphragm 2. Each vibrator 3 is attached to one diaphragm 2 one by one.

  As shown in FIG. 1, by adhering the outer periphery of the diaphragm 2 provided with the vibrator 3 to the step 4 from the front side, each diaphragm 2 is in a state where the front surface is flush with the front surface of the substrate 1. Attached to the substrate 1. Thereby, each diaphragm 2 is accommodated in the front end part 5b of the accommodation hole 5 without a gap, and each vibrator 3 is disposed in the rear part 5a of the accommodation hole 5 without contacting the substrate 1. In addition, by attaching each diaphragm 2 to the substrate 1 in this way, a circular portion corresponding to the rear portion 5a of each diaphragm 2 becomes a soundable portion 6 that can be vibrated and is not fixed to the substrate 1.

  Here, each vibrator 3 is accommodated in the rear part 5a of the accommodation hole 5 in a state where a part of the vibrator 3 protrudes rearward from the substrate 1 as shown in FIG. Further, as shown in FIG. 2 (b), the entire vibrator 3 is disposed within the thickness of the substrate 1 so that the vibrator 3 is completely housed in the rear portion 5 a of the housing hole 5. It may be.

  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 of the vibrators 3 vibrates based on the sound signal output from the sound source device, thereby vibrating the sound generating unit 6 of the diaphragm 2 to emit sound forward.

  The building panel with a speaker function described above can be used as a building panel with high strength because the main body is constituted by the substrate 1 in the same manner as a building panel without a general speaker function. Moreover, the sound generator 6 of the diaphragm 2 that constitutes part of the ceiling surface and part of the wall surface together with the front surface of the substrate 1 can be vibrated by the vibrator 3 to emit sound, and can also be used as a speaker. Can do.

  Moreover, since the front surface of the diaphragm 2 is flush with the front surface of the substrate 1, the entire front surface of the building panel with a speaker function is a flat surface without a step, and the appearance is good. In addition, since no step is formed between the front surface of the diaphragm 2 and the front surface of the substrate 1, the appearance is substantially the same as a general building panel.

  Each vibrator 3 is housed in the housing hole 5 as shown in FIG. 2A and FIG. 2B, so that the amount of protrusion from the substrate 1 to the rear is small or behind the substrate 1. Does not protrude. Therefore, when the building panel with a speaker function is attached to the base, the vibrator 3 can be prevented from interfering with other members, and workability is good. In particular, when the back surface of the substrate 1 is in direct contact with the ground, the vibrator 3 does not interfere with the ground.

  Moreover, the building panel with a speaker function of this example includes a plurality of vibrators 3. For this reason, sounds of a plurality of channels can be output.

  Next, another construction panel with a speaker function shown in FIG. 3 will be described. In the following description, the same reference numerals are given to the same components as those of the building panel with a speaker function as an example, and duplicate descriptions are omitted.

  The building panel with a speaker function shown in FIG. 3 has a wiring housing groove 8 that communicates with the rear portion 5 a of each housing hole 5 on the rear surface of the substrate 1. The wiring housing groove 8 includes a main groove 9 extending in the longitudinal direction of the substrate 1 and a plurality of sub grooves 10 extending in the short direction of the substrate 1.

  Both ends of the main groove 9 reach the end face in the longitudinal direction of the substrate 1 and are open. The sub-groove 10 has one end communicating with the main groove 9 and the other end communicating with the rear portion 5 a of the storage hole 5. Thereby, the rear part 5 a of each storage hole 5 communicates with the outside of the substrate 1 through the wiring storage groove 8.

  As shown in FIG. 3, the wiring storage grooves 8 can store the wirings 7 connected to the respective vibrators 3, so that the workability of the above-described building panel with a speaker function can be further improved. Moreover, it is not necessary to form a space for housing the wiring 7 behind the substrate 1, and the degree of freedom in construction increases.

  In addition, although the building panel with a speaker function of each of the above examples includes two vibrators 3, it may include one or three or more vibrators 3. . In addition, the position, shape, and size of the storage hole 5 in which the vibrator 3 is disposed can be appropriately changed according to the sound to be output.

  Next, still another building panel with a speaker function shown in FIG. 4 will be described. In the following description, the same reference numerals are given to the same components as those of the building panel with a speaker function as an example, and duplicate descriptions are omitted.

  In the building panel with a speaker function of this example, the diaphragm 2 is detachably attached to the substrate 1 from the front side of the substrate 1.

  Specifically, as shown in FIG. 4, locking portions 12 that protrude rearward are provided on both side portions of the diaphragm 2 across the vibrator 3. Each locking part 12 includes a protrusion 15 protruding outward from the rear end part, and is formed in an L shape.

  On the other hand, insertion grooves 14 penetrating in the thickness direction of the substrate 1 are formed at locations corresponding to the respective locking portions 12 on the inner peripheral surface of the rear portion 5 a of the storage hole 5 of the substrate 1. A damping material 13 is provided on the step 4 of the substrate 1.

  In order to attach the diaphragm 2 with the vibrator 3 to the substrate 1, the diaphragm 2 disposed on the front side of the substrate 1 is moved to the substrate 1 side as shown by the arrow in FIG. It arrange | positions through the damping material 13 in the front side of the step 4 of the board | substrate 1, and arrange | positions each latching | locking part 12 of the diaphragm 2 to the rear surface side of the board | substrate 1 through the corresponding insertion groove | channel 14, and after that, vibration By rotating the plate 2, the protrusions 15 of the respective locking portions 12 are locked to the rear surface side of the diaphragm 2.

  Further, in order to remove the diaphragm 2 with the vibrator 3 attached to the substrate 1 in this way, the engaging portions 12 are inserted into the insertion grooves 14 from the front side of the substrate 1. It rotates until it arrange | positions to a corresponding position, Then, the diaphragm 2 is moved to the front side, and each latching | locking part 12 is pulled out to the front side of the board | substrate 1 through the insertion groove | channel 14. FIG.

  Thus, in the building panel with speaker function of this example, the diaphragm 2 is detachable from the front side of the substrate 1, so that after the building panel with speaker function is installed, the room of the building panel with speaker function is provided. The diaphragm 2 can be removed or attached together with the vibrator 3 from the inside. In this case, it is not necessary to remove the substrate 1 from the base, and the maintenance of the diaphragm 2 and the vibrator 3 can be easily performed. Further, by sandwiching the damping material 13 between the diaphragm 2 and the stepped surface 4, it becomes difficult for vibration to be transmitted between the diaphragm 2 of the substrate 1 and the base 1, and sound quality can be improved.

  In this example, a single vibrator 3 is provided on the substrate 1, but a plurality of vibrators 3 may be provided on the substrate 1 as in the above examples.
