【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案はスピーカをキャビネットに組み込んだスピーカ装置に関するものであ る。 The present invention relates to a speaker device in which a speaker is incorporated in a cabinet.

【0002】[0002]

【従来の技術】[Prior Art]

従来のスピーカ装置は、スピーカキャビネットであるエンクロージャの前面の バッフル板にスピーカの個数に応じた開口を穿設し、この開口にスピーカを嵌挿 し、ネジにてスピーカをバッフル板に固定するのが一般的である。 In the conventional speaker device, openings are formed in the baffle plate on the front surface of the enclosure, which is a speaker cabinet, according to the number of speakers, and the speakers are inserted into the openings and the speakers are fixed to the baffle plate with screws. It is common.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記従来のスピーカ装置においては、スピーカの重心はスピーカの磁気回路部 分が重量比で大部分を占めるため、マグネットの後部すなわちスピーカ全体の後 部となる。また該スピーカをキャビネットに固定した場合、バッフル板部分でネ ジ止めした個所に、上記スピーカの重心部分での重量が掛かり、このスピーカの 重量を支えるだけの固定力が必要となる。 In the above-mentioned conventional speaker device, the center of gravity of the speaker is the rear part of the magnet, that is, the rear part of the entire speaker because the magnetic circuit part of the speaker occupies most of the weight ratio. Further, when the speaker is fixed to the cabinet, the weight of the center of gravity of the speaker is applied to the place where the baffle plate portion is screwed, and a fixing force is required to support the weight of the speaker.

【0004】 即ち、スピーカとキャビネットの重量の釣り合いは、スピーカの重量をmとし 、該スピーカの中心線上でスピーカの固定個所からスピーカの重心位置までの長 さをdとした場合、上記スピーカは固定したバッフル板に一端を固定した片持梁 の状態であり、該バッフル板の固定端にスピーカの重量mが、m×d[Kg・m ]の力として掛かることになる。従って、キャビネットのスピーカを取り付ける バッフル板には、強固な部材が必要となる。That is, if the weight of the speaker and the cabinet is balanced, and the weight of the speaker is m and the length from the fixing point of the speaker to the center of gravity of the speaker on the center line of the speaker is d, the speaker is fixed. In this state, one end is fixed to the baffle plate, and the weight m of the speaker is applied to the fixed end of the baffle plate as a force of m × d [Kg · m 2]. Therefore, a strong member is required for the baffle plate for mounting the speaker of the cabinet.

【0005】 また、スピーカのボイスコイルに音声に対応した電気信号が供給され振動板が 前後にピストン運動するとき、電気エネルギーを機械エネルギーに変換する際に 生じる前方への力をFとすると、力Fと反対の後方へも逆起電力により力(−) Fが生じるため、スピーカは常に振動板の振動方向に力が発生する。このスピー カの前後方向への力は、ネジ及びバッフル板を介してキャビネット全体に振動と して伝播する。Further, when an electric signal corresponding to a voice is supplied to the voice coil of the speaker and the diaphragm moves back and forth in a piston motion, when a forward force generated when converting electric energy into mechanical energy is F, Since a force (−) F is also generated in the backward direction opposite to F by the counter electromotive force, the speaker always generates a force in the vibration direction of the diaphragm. The force of the speaker in the front-back direction propagates as vibration to the entire cabinet via the screws and the baffle plate.

【0006】 上記キャビネットに伝播される振動によりキャビネットやその他の部品等で共 振が起き、従って共振音が発生する。これらの共振音は、スピーカから発生する 音以外のものであり所謂不快な雑音である。上記のような雑音の発生は、スピー カシステムの性能を損なうものである。The vibrations propagated to the cabinet cause resonance in the cabinet and other parts, thus generating resonance noise. These resonance sounds are so-called unpleasant noises other than the sound generated from the speaker. The generation of noise as described above impairs the performance of the speaker system.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

本考案のスピーカ装置は、キャビネットの内部に通気孔を有する補強板を設け 、該補強板の前壁に弾性材を装着し、バッフル板の開口に嵌挿したスピーカの後 部を上記弾性材に押圧し保持して該スピーカをバッフル板に固定してなることを 特徴とするものである。 In the speaker device of the present invention, a reinforcing plate having a ventilation hole is provided inside the cabinet, an elastic material is attached to the front wall of the reinforcing plate, and the rear portion of the speaker fitted in the opening of the baffle plate is made of the elastic material. The speaker is characterized in that it is pressed and held to fix the speaker to a baffle plate.

【実施例】【Example】

本考案のスピーカ装置の実施例を図面と共に説明すると、図1は本装置の一部 分解断面図であり、図2は本装置の断面図である。 An embodiment of the speaker device of the present invention will be described with reference to the drawings. FIG. 1 is a partially exploded cross-sectional view of the device, and FIG. 2 is a cross-sectional view of the device.

【0009】 図1において、スピーカ1は従来からある代表的なコーン型スピーカで、マグ ネット,ヨーク等からなる磁気回路部2、ボイスコイルを捲回したボビン3、該 ボビン3に装着されたコーン型振動板4及びダンパー5、該ダンパー5の外周縁 を固着するフレーム6、該振動板4の外周エッジを固着するフレーム6の外周固 定部7等からなる。In FIG. 1, a speaker 1 is a conventional typical cone-type speaker, which includes a magnetic circuit unit 2 including a magnet and a yoke, a bobbin 3 around which a voice coil is wound, and a cone mounted on the bobbin 3. The mold vibrating plate 4 and the damper 5, the frame 6 for fixing the outer peripheral edge of the damper 5, the outer peripheral fixing portion 7 of the frame 6 for fixing the outer peripheral edge of the diaphragm 4 and the like.

【0010】 一方、スピーカキャビネットであるエンクロージャ8のバッフル板9に、上記 スピーカ1が嵌挿し得る開口10を穿設し、該エンクロージャ8の内部に例えば 内容積を2分割する如く、通気孔11,12を有する補強板13を設ける。上記 補強板13の前壁に、スピーカ5が嵌挿された状態で円錐台形状の磁気回路部分 2がはまり得る円形の保持凹部14を穿設する。即ち上記補強板13の保持凹部 14の径はスピーカ1の磁気回路部分2の径より少し大きく、またバッフル板9 の前面から補強板13の保持凹部14の面までの長さaは、スピーカ1の外周固 定部7から磁気回路部分2までの所謂スピーカ1の高さbより少し長く設定する 。On the other hand, a baffle plate 9 of an enclosure 8 which is a speaker cabinet is provided with an opening 10 into which the speaker 1 can be fitted, and a ventilation hole 11 is formed inside the enclosure 8 so as to divide the internal volume into two, for example. A reinforcing plate 13 having 12 is provided. The front wall of the reinforcing plate 13 is provided with a circular holding recess 14 into which the frustoconical magnetic circuit portion 2 can be fitted while the speaker 5 is fitted therein. That is, the diameter of the holding recess 14 of the reinforcing plate 13 is slightly larger than the diameter of the magnetic circuit portion 2 of the speaker 1, and the length a from the front surface of the baffle plate 9 to the surface of the holding recess 14 of the reinforcing plate 13 is It is set to be slightly longer than the height b of the so-called speaker 1 from the outer peripheral fixing portion 7 to the magnetic circuit portion 2.

【0011】 上記補強板13の保持凹部14には、厚さcの比較的厚いゴム等の弾性材15 を該保持凹部14の内壁に沿って接着剤等で装着する。尚符号16はエンクロー ジャ8を密閉する背板である。An elastic material 15 such as rubber having a relatively large thickness c is attached to the holding recess 14 of the reinforcing plate 13 along the inner wall of the holding recess 14 with an adhesive or the like. Reference numeral 16 is a back plate for sealing the enclosure 8.

【0012】 上記構成のエンクロージャ8の開口10にスピーカ1を嵌挿し、図2に示す如 く、スピーカ1の磁気回路部分2で弾性材15を押圧しながらフレーム6の外周 固定部7をビス17,18でバッフル板9に固定する。ここで、上記バッフル板 9の前面から補強板13の保持凹部14の面までの長さaとスピーカの高さbと の差、即ち図2におけるスピーカ1の磁気回路部分2と保持凹部14の面までの 間隔dは、弾性材15の厚さcより小さくなる。The speaker 1 is inserted into the opening 10 of the enclosure 8 having the above-described configuration, and the outer peripheral fixing portion 7 of the frame 6 is screwed 17 while pressing the elastic member 15 with the magnetic circuit portion 2 of the speaker 1 as shown in FIG. , 18 to fix to the baffle plate 9. Here, the difference between the length a from the front surface of the baffle plate 9 to the surface of the holding recess 14 of the reinforcing plate 13 and the height b of the speaker, that is, the magnetic circuit portion 2 and the holding recess 14 of the speaker 1 in FIG. The distance d to the surface is smaller than the thickness c of the elastic material 15.

【0013】 本装置は叙上のような構成であるから、スピーカ1はバッフル板9と弾性板1 3間で保持され、両端支持梁の状態となり、従来のスピーカ装置のようにスピー カをバッフル板で固定支持した片持梁の状態のものと比較して、スピーカ1のB点 での重量mがバッフル板1側のA点と補強板13側のC点とで支えられ両端支持 梁の状態となり、バッフル板1に対する重量の負担が軽減され、装置全体として 安定したものとなる。Since this device has the above-described configuration, the speaker 1 is held between the baffle plate 9 and the elastic plate 13 and is in a state of supporting beams at both ends, so that the speaker is baffled like a conventional speaker device. Compared with the cantilever beam fixedly supported by the plate, the weight m of the speaker 1 at the point B is supported by the point A on the baffle plate 1 side and the point C on the reinforcing plate 13 side, and As a result, the burden of weight on the baffle plate 1 is reduced, and the entire device becomes stable.

【0014】 また、スピーカ1のボイスコイルに音声に対応した電気信号が供給され、振動 板4が振動して生じる力F若しくは(−)Fが弾性材15で吸収されるため、エ ンクロージャ8への振動伝播が軽減され、エンクロージャ8等で発生する共振音 を減少させることができる。Further, an electric signal corresponding to a voice is supplied to the voice coil of the speaker 1, and the force F or (−) F generated by the vibration of the diaphragm 4 is absorbed by the elastic material 15, so that the enclosure 8 is closed. Vibration propagation to the enclosure is reduced, and resonance noise generated in the enclosure 8 and the like can be reduced.

【0015】[0015]

【考案の効果】 本考案によるスピーカ装置は、スピーカのエンクロージャへの固定はより安定 となり、またスピーカの動作時に生じる不要な振動のエンクロージャへの伝播が 減少するため、エンクロージャ等で発生する共振音等の雑音が小さくなり、より 原音再生に優れたものとなる。EFFECTS OF THE INVENTION In the speaker device according to the present invention, the fixing of the speaker to the enclosure becomes more stable, and unnecessary vibration generated during the operation of the speaker is reduced to propagate to the enclosure. The noise of is reduced, and the original sound is better reproduced.
