Description

本発明はスピーカー機能付き建築用パネルに関する。   The present invention relates to a building panel with a speaker function.

例えば特許文献1に示すように部屋の天井の一部にスピーカーを設置する場合がある。   For example, as shown in Patent Document 1, a speaker may be installed on a part of a ceiling of a room.

ところで、この種のスピーカーは、本来、建物の天井を構成するものではないため、天井にスピーカーが設けられたことが一目でわかり、部屋が統一感のないものとなる。   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.

また、特許文献1のスピーカーは、トランスデューサーを設けた振動板の周縁部がフレームで支持され、フレームと振動板との間に段差が形成される。このため、見栄えが悪く、またフレームの内側に振動板を設けたスピーカーであることが容易に認識でき、この点でも部屋は統一感のないものとなる。   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.

また、このスピーカーを取り付ける際には、振動板の裏面側に突出するトランスデューサーが他の部材に干渉する恐れがある等、施工性が悪い。また、このスピーカーにおける振動板は周縁部のみがフレームで支持されるものであり、天井を構成する部材としては強度が低い。
特許第3763848号(35頁、図25)
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.
Japanese Patent No. 3763848 (page 35, FIG. 25)

本発明は上記従来の問題点に鑑みてなされたものであって、一般の建築用パネルと同様に利用することができ、尚且つ、スピーカーとしても利用することができ、しかも外観及び施工性の優れたスピーカー機能付き建築用パネルを提供することを課題とする。   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.

上記課題を解決するために請求項1に係るスピーカー機能付き建築用パネルは、基板1に前面に開口する収納孔5を形成し、該収納孔5の前端部5bの開口縁を後方部5aよりも拡大して段4を形成し、該段状に形成された収納孔5の前端部5bに振動板2を収納孔5の開口を閉塞するように配設すると共に該振動板2の前面を基板1の前面と面一とし、振動板2の後面中央に加振器3を設けることを特徴とする。   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.

また、前記基板1に収納孔5に通じる配線収納溝8を形成することが好ましい。   Further, it is preferable to form a wiring housing groove 8 communicating with the housing hole 5 in the substrate 1.

また、前記加振器3を基板1の厚み内に配置することが好ましい。   Moreover, it is preferable to arrange the vibrator 3 within the thickness of the substrate 1.

また、前記振動板2を基板1に対して基板1の前面側から着脱自在に取り付けることが好ましい。   The diaphragm 2 is preferably detachably attached to the substrate 1 from the front side of the substrate 1.

請求項1では、一般のスピーカー機能を備えていない建築用パネルと同様に、基板により主体が構成されるため、強度の高い建築用パネルとして利用することができる。また、加振器により、基板の前面と共に天井面の一部や壁面の一部を構成する振動板の発音部を振動させ、音を発することができ、スピーカーとしても利用することができる。   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.

また、振動板の前面を基板の前面と面一とするため、見栄えが良い。また、振動板の前面と基板の前面との間に段差が形成されないため、一般の建築用パネルと略同じ外観となる。また、加振器を収納孔に収納でき、スピーカー機能付き建築用パネルの際には、加振器が他の部材に干渉することを防止でき、施工性が良い。   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.

また請求項2では、加振器に接続される配線を配線収納溝に収納することができ、スピーカー機能付き建築用パネルの施工性をさらに向上できる。また、基板の後方に配線を収納するためのスペースを形成する必要がなく、施工の自由度が増す。   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.

また請求項3では、加振器を基板の厚み内に配置することができるため、基板を下地の前面に取り付ける場合に、加振器が他の部材にさらに干渉し難くなる。   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.

また請求項4では、スピーカー機能付き建築用パネルの設置後において、スピーカー機能付き建築用パネルの室内側から振動板を加振器と共に取り外したり取り付けたりすることができ、この場合、基板を下地から取り外す等する必要がなく、振動板や加振器のメンテナンスを容易に行うことができる。   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.

以下、本発明の実施形態の一例を添付図面に基づいて説明する。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

図1に示す本実施形態の一例のスピーカー機能付き建築用パネルは、建物の桟や下地板等(以下、単に下地と記載する)に取り付けられ、天井材や壁材等の建築用パネルとして利用されるものである。なお、以下ではスピーカー機能付き建築用パネルの設置状態における室内側を前側として説明する。   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.

スピーカー機能付き建築用パネルは矩形状(図示例では長方形状)に形成され、建物の下地に取り付けられる基板1と、基板1の前面側に設けられる複数の振動板2と、振動板2の後面に設けられて振動板2を振動させる加振器3とで構成されている。   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.

基板1は木質材料で形成され、振動板2と比べて厚みが大きくなっている。   The substrate 1 is made of a wood material and is thicker than the diaphragm 2.

長方形状に形成された基板1の長手方向における両側部分には、基板1の前面側に開口する収納孔5が形成されている。各収納孔5は基板1の厚み方向(前後方向)に貫通する孔からなる。   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.

各収納孔5は、前端部5bの開口縁を後方部5aよりも拡大して段4を形成した孔からなる。図示例では、後方部5aが円形の孔からなり、前端部5bが後方部5aよりも大径の孔からなる。   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.

後方部5aの内周面と前端部5bの内周面は正面視環状の段4を介して接続されている。基板1は収納孔5が形成されていない部分が大部分を占め、強度が高められている。   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.

段状に形成された各収納孔5の前端部5bには収納孔5を閉塞するように振動板2が配設され、また、後方部5aには各振動板2の後面に設けられた加振器3が配置される。   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.

各振動板2は円形に形成され、その直径及び厚みは前端部5bの内径及び深さと略同じである。各振動板2は加振器3によって振動しやすいよう基板1と比べて弾力性に富んだ材料からなる。具体的には、振動板2は発泡ポリプロピレンからなる。   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.

加振器3は各振動板2の中央に設けられる。各加振器3は一枚の振動板2に対して一個ずつ取り付けられる。   The vibrator 3 is provided at the center of each diaphragm 2. Each vibrator 3 is attached to one diaphragm 2 one by one.

図1に示すように、加振器3が設けられた振動板2の外周部を前側から段4に接着することで、各振動板2は前面が基板1の前面と面一とした状態で基板1に取り付けられる。これにより、各振動板2は隙間なく収納孔5の前端部5bに収納され、また、各加振器3は基板1と接触しない状態で収納孔5の後方部5aに配置される。また、このように各振動板2を基板1に取り付けることで、各振動板2の後方部5aに対応する円形部分は基板1に固定されない振動可能な発音部6となる。   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.

ここで、各加振器3は、図2(a)に示すように加振器3の一部が基板1よりも後方に突出した状態で収納孔5の後方部5aに収納されるものであっても良く、また、図2(b)に示すように加振器3が収納孔5の後方部5aに完全に収納されるように加振器3の全体が基板1の厚み内に配置されるものであっても良い。   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.

前記各加振器3は図示しない音声用アンプ等の音源装置に配線7(図3参照)を介して接続される。各加振器3は、音源装置から出力された音声信号に基づいて振動し、これにより振動板2の発音部6を振動させ、音を前方に発する。   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.

以上説明したスピーカー機能付き建築用パネルは、一般のスピーカー機能を備えていない建築用パネルと同様に、基板1により主体が構成されるため、強度の高い建築用パネルとして利用することができる。また、加振器3により、基板1の前面と共に天井面の一部や壁面の一部を構成する振動板2の発音部6を振動させ、音を発することができ、スピーカーとしても利用することができる。   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.

また、振動板2の前面は基板1の前面と面一となるため、スピーカー機能付き建築用パネルの前面の全体が段差のない平坦な面となり、見栄えが良い。また、振動板2の前面と基板1の前面との間に段差が形成されないため、一般の建築用パネルと略同じ外観となる。   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.

また、各加振器3は図2(a)及び図2(b)に示すように収納孔5に収納されるため、基板1からの後方への突出量が小さい、又は基板1よりも後方に突出しない。従って、スピーカー機能付き建築用パネルを下地に取り付ける際に、加振器3が他の部材に干渉することを防止でき、施工性が良い。特に基板1の背面を下地に直接当接する際に加振器3が下地に干渉せず、良い。   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.

また、本例のスピーカー機能付き建築用パネルは複数の加振器3を備えたものである。このため、複数チャンネルの音を出力することができる。   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.

次に図3に示す他例のスピーカー機能付き建築用パネルについて説明する。なお以下の説明では一例のスピーカー機能付き建築用パネルと同一の構成については同一の番号を付与し、重複する説明は省略する。   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.

図3に示すスピーカー機能付き建築用パネルは、基板1の後面に各収納孔5の後方部5aに通じる配線収納溝8を形成している。配線収納溝8は、基板1の長手方向に伸びる主溝9と、基板1の短手方向に伸びる複数の副溝10とで構成されている。   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.

主溝9の両端はそれぞれ基板1の長手方向の端面に至り、開口している。副溝10は一端が主溝9に連通すると共に他端が収納孔5の後方部5aに連通している。これにより各収納孔5の後方部5aは配線収納溝8を介して基板1の外方に連通している。   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.

前記配線収納溝8には図3に示すように各加振器3に接続された配線7を収納することができ、前述のスピーカー機能付き建築用パネルの施工性をさらに向上できる。また、基板1の後方に配線7を収納するためのスペースを形成する必要がなく、施工の自由度が増す。   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.

なお、前記各例のスピーカー機能付き建築用パネルは加振器3を2個備えたものであるが、1個又は3個以上の加振器3を備えたものであっても良いものとする。また、加振器3が配される収納孔5の位置や形状、大きさも、出力する音等に応じて適宜変更可能である。   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.

次に図4に示す更に他例のスピーカー機能付き建築用パネルについて説明する。なお以下の説明では一例のスピーカー機能付き建築用パネルと同一の構成については同一の番号を付与し、重複する説明は省略する。   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.

本例のスピーカー機能付き建築用パネルは、前記振動板2を基板1に対して基板1の前面側から着脱自在に取り付けている。   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.

具体的には、図4に示すように、振動板2の加振器3を挟んだ両側部分には後方に向けて突出する係止部12が設けられている。各係止部12は後端部から外側に向けて突出した突部15を備え、L字状に形成されている。   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.

一方、基板1の収納孔5の後方部5aの内周面の各係止部12に対応する箇所には、基板1の厚み方向に貫通する挿通溝14が形成されている。基板1の段4上には制震材13が設けられている。   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.

加振器3付きの振動板2を基板1に取り付けるには、図4の矢印に示すように、基板1の前側に配置した振動板2を基板1側に移動することで、振動板2を基板1の段4の前側に制震材13を介して配置すると共に、振動板2の各係止部12を対応する挿通溝14に通して基板1の後面側に配置し、この後、振動板2を回動して、各係止部12の突部15を振動板2の後面側に係止する。   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.

また、このように基板1に取り付けられた加振器3付きの振動板2を取り外すには、前記とは逆に、基板1の前側から振動板2を各係止部12が挿通溝14に対応する位置に配されるまで回動し、この後、振動板2を前側に移動して、各係止部12を挿通溝14を通して基板1の前側に引き抜く。   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.

このように本例のスピーカー機能付き建築用パネルは、前記振動板2を基板1の前側から着脱自在としてあるので、スピーカー機能付き建築用パネルの設置後においては、スピーカー機能付き建築用パネルの室内側から振動板2を加振器3と共に取り外したり、取り付けたりすることができる。そして、この場合、基板1を下地から取り外す等する必要がなく、振動板2や加振器3のメンテナンスを容易に行うことができる。また、振動板2と段差面4との間に制震材13を挟むことにより、基板1の振動板2と基盤1との間で振動が伝わり難くなり、音質を向上できる。   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.

なお、本例では基板1に一個の加振器3を設けたものであるが、前記各例と同様に基板1に複数の加振器3を設けても良いものとする。   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.
