上記した従来の体感振動子では筒体と同心に配置した一枚の環状リーフスプリ ングによって磁極の重量を支えているので、筒体の軸心が鉛直方向を向くように ケースをシート等に水平に取付けたときは磁極の重量がリーフスプリングの各部 に均一に加わるものの、ケースを傾けて取付けると磁極の重量がリーフスプリン グに対し局部的に集中して加わる。このため、磁極がリーフスプリングによりバ ランス良く支持されないので、ケースの振動が不安定になる。 また、リーフスプリングの金属疲労が局部的に進行するので、短期間で弾性体 として機能しなくなる。 本考案はかかる問題点に鑑み、安定した振動特性と高い耐久性を得ることので きる体感振動子を提供することを目的とする。 In the above-mentioned conventional sensible vibrator, the weight of the magnetic pole is supported by a single annular leaf spring arranged concentrically with the cylinder, so the case is placed horizontally on a sheet or the like so that the axis of the cylinder is oriented vertically. When attached, the weight of the magnetic pole is evenly applied to each part of the leaf spring, but if the case is tilted and attached, the weight of the magnetic pole is locally concentrated on the leaf spring. For this reason, the magnetic poles are not well supported by the leaf springs, and the vibration of the case becomes unstable. Further, the metal fatigue of the leaf spring locally progresses, so that the leaf spring does not function as an elastic body in a short period of time. The present invention has been made in view of the above problems, and an object of the present invention is to provide a sensible vibrator capable of obtaining stable vibration characteristics and high durability.

【実施例】【Example】

以下に本考案を図面に基づき説明するに、図1及び図2には本考案の一実施例 に係る体感振動子10が示されている。 当該振動子10は有底円筒状のケース11、同ケース11の上部開口を覆蓋す るカバー12、ケース11に内蔵した磁極13及びボイスコイル14を巻回した 円筒体15を備えている。 The present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a sensible vibrator 10 according to an embodiment of the present invention. The vibrator 10 includes a cylindrical case 11 having a bottom, a cover 12 for covering an upper opening of the case 11, a magnetic pole 13 built in the case 11, and a cylindrical body 15 around which a voice coil 14 is wound.

【0007】 磁極13は下端にフランジ部16aを有する円柱状のヨーク16、同ヨーク1 6を取り囲むようにフランジ部16aに載置して接着固定した環状の磁石17、 磁石17の上面に接着固定した環状のアッパプレート18からなり、ヨーク16 、磁石17及びアッパプレート18は互いに同心状に組付けられてヨーク16と 磁石17間に隙間を有する磁気回路を構成している。また、フランジ部16aと アッパプレート18の外径は磁石17の外径より若干短く設定され、フランジ部 16aとアッパプレート18の外周部及び磁石17の上下両面により環状の段部 17a,17bが区画形成されている。The magnetic pole 13 has a cylindrical yoke 16 having a flange portion 16 a at its lower end, an annular magnet 17 placed on the flange portion 16 a so as to surround the yoke 16 and adhesively fixed, and an adhesive fixing to the upper surface of the magnet 17. The yoke 16, the magnet 17, and the upper plate 18 are assembled concentrically with each other to form a magnetic circuit having a gap between the yoke 16 and the magnet 17. The outer diameters of the flange portion 16a and the upper plate 18 are set to be slightly smaller than the outer diameter of the magnet 17, and the annular step portions 17a and 17b are defined by the outer peripheral portion of the flange portion 16a and the upper plate 18 and the upper and lower surfaces of the magnet 17. Has been formed.

【0008】 ケース11の内壁には半円形の断面形状を有する凸条11aが等角度間隔で中 心線と平行に設けられ、隣合う凸状11a同士によって溝状の凹部11bが区画 形成されている。 磁極13はこの溝状凹部11bと環状段部17a,17bの間に圧入したゴム チューブ19を介することによりフランジ部16aがケース11の底面から浮き 上がった状態でケース11の内壁に取付けられている。このゴムチューブ19は 図2に示すように、部位によって粗密に配置されている。On the inner wall of the case 11, ridges 11a having a semicircular cross-sectional shape are provided at equal angular intervals in parallel with the center line, and adjacent ridges 11a form groove-shaped recesses 11b. There is. The magnetic pole 13 is attached to the inner wall of the case 11 with the flange portion 16a lifted from the bottom surface of the case 11 through a rubber tube 19 press-fitted between the groove-shaped recess 11b and the annular step portions 17a, 17b. .. As shown in FIG. 2, the rubber tubes 19 are arranged in a dense and dense manner depending on the parts.

【0009】 また、カバー12の内側にはインナープレート20が取付けられ、カバー12 とともにネジ21でケース11の上端部に固着されている。このインナープレー ト20には中心部に通孔20aが形成されている。一方、円筒体15の上部外周 にはゴム等の絶縁体からなるリングプリート22が接着固定されている。円筒体 15はボイスコイル14がヨーク16と磁石17間の隙間に挿入されるようにこ の中心孔20aを通してヨーク16に被せられ、リングプレート20をネジ23 でインナープレート22に固着してケース11に固定されている。An inner plate 20 is attached inside the cover 12, and is fixed to the upper end of the case 11 together with the cover 12 with a screw 21. The inner plate 20 has a through hole 20a formed in the center thereof. On the other hand, a ring plate 22 made of an insulating material such as rubber is adhered and fixed to the outer periphery of the upper portion of the cylindrical body 15. The cylindrical body 15 is put on the yoke 16 through the center hole 20a so that the voice coil 14 is inserted into the gap between the yoke 16 and the magnet 17, and the ring plate 20 is fixed to the inner plate 22 with the screw 23 to form the case 11 It is fixed to.

【0010】 本実施例に係る体感振動子は以上の構成からなり、ボイスコイル14に音声信 号電流を加えると、磁極13とボイスコイル14間に磁気干渉作用が生じ、これ により磁極13がケース11に対し相対的に変位して体感振動が発生する。 しかして本実施例によれば、ケース11内壁の複数箇所に溝状凹部11bを設 け、同凹部11bに挿入したゴムチューブ19を介して磁極13をケース11に 取付けたので、ケース11内壁の部位に応じてゴムチューブ19の個数や硬度を 変えることによりゴムチューブ19の支持力を調整できる。このため、例えば図 3に示すように体感振動子10をシート30のシートクッション部31に水平に 取付ける場合にはゴムチューブ19をケース11の内壁に均一に配設し、シート バック部32に取付ける使用する場合には、ケース11内壁の各部位のうち磁極 13の重量が集中して加わる部位には他の部位に比べて数多くのゴムチューブ1 9を配設することにより、ケース11の取付角度にかかわらず磁極13をケース 11に対しバランス良く支持することが可能となる。このため、ボスイコイル1 4に音声信号を加えたとき発生する振動が安定する。また、個々のゴムチューブ 19に加わる力が均一になるので、同チューブ19の耐久性が向上する。The sensible vibrator according to the present embodiment has the above-described configuration. When a voice signal current is applied to the voice coil 14, a magnetic interference action occurs between the magnetic pole 13 and the voice coil 14, which causes the magnetic pole 13 to move to the case. Displacement relative to 11 generates a sensory vibration. According to this embodiment, however, the groove-like recessed portions 11b are provided at a plurality of locations on the inner wall of the case 11, and the magnetic poles 13 are attached to the case 11 via the rubber tubes 19 inserted into the recessed portions 11b. The supporting force of the rubber tube 19 can be adjusted by changing the number and hardness of the rubber tube 19 depending on the part. Therefore, for example, when the sensible vibrator 10 is horizontally attached to the seat cushion portion 31 of the seat 30 as shown in FIG. In the case of use, the mounting angle of the case 11 is increased by arranging a larger number of rubber tubes 19 in the parts of the inner wall of the case 11 where the weight of the magnetic pole 13 is concentrated than in other parts. Regardless of this, the magnetic pole 13 can be supported on the case 11 in good balance. Therefore, the vibration generated when an audio signal is applied to the Bossie coil 14 is stabilized. Further, since the force applied to each rubber tube 19 becomes uniform, the durability of the tube 19 is improved.

【0011】 なお、本実施例ではゴムチューブ19を介して磁極13をケース11に取付け たが、ゴム製弾性体としては、このほかゴム製ボールやゴム製ブロックを挙げる ことができる。 また、本実施例ではゴムチューブ19を挿入する凹部として溝状凹部11bを ケース11の内壁に設けたが、ゴム製弾性体としてゴム製ボールやゴム製ブロッ クを使用する場合にはその形状、寸法に合わせて凹部の形状、寸法を変更すべき はもちろんである。 さらに、ゴム製弾性体と環状のリーフスプリングを併用すれば、一層耐久性、 振動の安定性が向上する。Although the magnetic pole 13 is attached to the case 11 via the rubber tube 19 in this embodiment, the rubber elastic body may be a rubber ball or a rubber block. Further, in the present embodiment, the groove-shaped recess 11b is provided on the inner wall of the case 11 as the recess into which the rubber tube 19 is inserted, but when a rubber ball or a rubber block is used as the rubber elastic body, its shape, Of course, the shape and size of the recess should be changed according to the size. Furthermore, if a rubber elastic body and an annular leaf spring are used together, durability and vibration stability are further improved.
