Description

【０００１】
【発明の属する技術分野】
本発明は、省電力タイプの携帯電話震動装置に係り、特に携帯電話着信時の震動時の電力消耗を極限に抑えつつ、震動時間を維持させる省電力タイプの携帯電話震動装置に関わる。
【０００２】
【従来の技術】
携帯電話を使用する際、着信の音楽が他人の妨げとならないよう、震動によって着信を知らせる機能が既に普及している。
その震動装置の主な構造を簡単に説明すれば、着信によって電流が相通するとモータや震動モータが駆動し、これらモータの回転軸が偏心軸を連動して回転させ、該偏心軸のぶつかりによって震動が起こるようになっている。
【０００３】
【発明が解決しようとする課題】
しかし上述のような公知における震動装置には、次のような欠点がある。
それは携帯電話が着信を知らせる震動を開始してから電話を受けるまで、震動モータが回転を続けることにあり、こうすることで大量の電力を消耗してしまうことである。
そこで携帯電話の限られた電力を有効に利用するべく、本発明の省電力タイプの携帯電話震動装置を提供する。
【０００４】
【課題を解決するための手段】
携帯電話の外殻内に、少なくとも一つ以上の弾力部と震動部とを設け、該震動部を該弾力部上に設置し、該弾力部は自由な周波の震動を固有し、且つ該震動部の震動方向に依って震動するのであり、更に該震動部上には出力部を設け、且つ該出力部のもう一端は電磁コイルに相対させ、こうすることで携帯電話の着信時に震動回路が駆動し、該出力部が該震動部にある一定の周波の外力を施し、該出力部が該震動部上で出力する外力の角周波で該弾力部を共振させ、出力部が震動部を伴って該弾力部上で震動し、少ない消耗電力で震動を維持させる。
【０００５】
【発明実施の形態】
図１，２に示すように、本発明は主に外殻１０内の設置個所に設けることで電話の着信を知らせるべく震動を起す装置である。また該外殻内には該外殻１０によって圧縮されている弾力部２０を具有し、該弾力部２０上には板状を呈した震動部３０が固設されている。こうして該震動部３０が該弾力部２０の圧縮に伴って動くことで該震動部３０が震動するようになっている。
該震動部３０は弾力部２０の中心に位置し、該弾力部２０の圧縮方向と平行で突設されている出力部４０が設けられている。
該出力部４０とは電磁力によって吸引されて動く金属の円柱状を呈した棒であり、もう一端には該外殻上に固定されている電磁コイル５０と相対している。
該電磁コイル５０においては、その電流は携帯電話着信時に震動回路が駆動し、並びに周期性をもった電流の導通により、該出力部４０が該震動部３０に対してある一定の周期で外力を提供するようになる。
該出力部４０からの外力と、該震動部３０の震動を受ける該弾力部２０の内応力及び抵抗の整合により、該出力部４０の外力作用角周波ωは、該弾力部２０の自由な固有周波数ωοと等しくなる（ω＝ωο）、即ち共振作用の関係となる。
【０００６】
携帯電話が着信する際、該電磁コイル５０が周期性を以って励磁され、該出力部４０が該弾力部２０の圧縮方向に運動し、こうすることで該震動部３０が該弾力部２０上で震動すると同時に、少ない電力で該震動部３０の震動を維持することができるようになる。該震動部３０が維持する震動作用により、該弾力部２０などの各部位も力の伝動を続け、こういったエネルギーが該外殻１０上に伝わり、震動となって使用者に伝えることができるのである。
また該出力部４０は該電磁コイル５０が励磁されることにより、該震動部３０の中心に駆動や震動の外力を発生させる。更に該震動部３０上には、二つ或いは二つ以上のパイロット桿３１が設けられており、これは該出力部４０の出力方向と平行を配置されており、且つ平滑な表面を具有し、こうして該震動部３０が更に安定して該弾力部２０上にて震動を続けることができるようになっている。
【０００７】
上述により、該震動部３０の震動は抵抗ｂを受け、周期性を以って該出力部４０の外力が該震動部３０を該弾力部２０上にて震動を維持するようになっており、該出力部４０の外力角周波ωが該弾力部２０の自由な固有周波数ωοと等しくなり（ω＝ωο）、該震動部３０を制御する震動品質Ｑｒは、該出力部５０の外力エネルギを最低限で消耗される。震動の過程における保存エネルギーと消耗エネルギーとの関係式は
【式１】

Figure 2004223336
適切な材料を用いるという条件下で、明かに該震動部３０の質量ｍ（この質量とは出力部の質量を加えた質量）、及び弾力部２０の弾力係数ｋ、及び抵抗力ｂは増加せず（或いは過大な増加をせず）、つまり震動の品質Ｑｒをほどよくコントロールできることになり、非常に有効な省電力効果を上げることができる。
【０００８】
また上述の実施例により、該震動部３０は剛性を具有する金属などによるものがよく、相当な応力を具有する材質を選択することにより、変形による震動への悪影響を防止することができる。
該震動部３０の震動を震動エネルギーを外殻上に伝動するのみとする他、図３に示すような実施例では、該震動部３０の両端にそれぞれ一つづつ、該震動部３０上で扇型を描いて運動する振り子３２を枢設する。該振り子３２は剛性を具有する材質によるものであり、該振り子３２のもう一端にはハンマーヘッド３２１が設けられている。また該震動部３０の枢設個所は、該外殻１０に設けられた支部１００付近に位置しており、該支部１００の支えによって該ハンマーヘッド３２１が相対運動を起し（図４参照）、尚該外殻１０上にぶつかるため、該外殻１０の震動効果が更に顕著に高められる。該ハンマーヘッド３２１が該外殻１０にぶつかるとき、ちょうど該震動部３０の震動過程の動勢に反する位置にあたり、よって過大な抵抗力が生まれないため、電力が極力少ない状態で震動が維持される。
【０００９】
また図５に示すように、該震動部３０上に設置される弾力部２０は二個、或いは二個以上としても、上述同様の項かが得られる。
更に図６に示すように、該震動部３０の震動は振り子式によって提供される震動としてもよく、弾力部２０Ａと震動部３０Ａの一端を連結させ、該弾力部２０Ａの湾曲や伸縮が、該震動部３０Ａを該弾力部２０固有の自由な周波によって扇形に震動し、且つ該震動部３０Ａのもう一端は磁力によって引かれる磁石や金属による出力部４０Ａを設け、該出力部４０Ａは震動部３０Ａ上の震動する方向に対応して設けられており、且つ磁力を発生させることのできる電磁コイル５０Ａを更に相対した個所に設ける。
こうすることで携帯電話の着信によって電磁コイル５０Ａに電流が流れ、周期性を以って該出力部４０Ａに引っ張る力を提供し、即ち該引っ張る力が震動部３０Ａに対する外力となり、該震動部３０Ａの該弾力部２０Ａ上における震動を起し、且つ維持することができるようになる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a power-saving type mobile phone vibration device, and more particularly to a power-saving type mobile phone vibration device that maintains vibration time while minimizing power consumption during vibration when a mobile phone arrives.
[0002]
[Prior art]
When using a mobile phone, a function of notifying an incoming call by shaking has already been widely used so that incoming music does not disturb others.
If the main structure of the vibration device is briefly described, when a current passes by an incoming call, a motor or a vibration motor is driven, and the rotating shafts of these motors rotate the eccentric shafts in an interlocking manner. Is supposed to happen.
[0003]
[Problems to be solved by the invention]
However, the above known vibration devices have the following disadvantages.
The reason is that the vibration motor keeps rotating from the time when the mobile phone starts the vibration to notify the incoming call to the time when the telephone is received, which consumes a large amount of power.
Therefore, in order to effectively use the limited power of the mobile phone, the present invention provides a power-saving type mobile phone vibration device of the present invention.
[0004]
[Means for Solving the Problems]
At least one elastic part and a vibrating part are provided in an outer shell of the mobile phone, and the vibrating part is installed on the elastic part. Vibrates depending on the direction of vibration of the part, and furthermore, an output part is provided on the vibrating part, and the other end of the output part is opposed to the electromagnetic coil. Drive, the output section applies an external force of a certain frequency to the vibration section, the output section resonates the elastic section at an angular frequency of the external force output on the vibration section, and the output section accompanies the vibration section. Then, the vibration is generated on the elastic portion, and the vibration is maintained with less power consumption.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, the present invention is a device that is mainly provided at an installation location in an outer shell 10 to generate a vibration to notify an incoming call. The outer shell has an elastic portion 20 compressed by the outer shell 10, and a plate-shaped vibration portion 30 is fixed on the elastic portion 20. In this way, the vibrating section 30 moves in accordance with the compression of the elastic section 20, so that the vibrating section 30 vibrates.
The vibrating section 30 is located at the center of the elastic section 20 and has an output section 40 projecting parallel to the compression direction of the elastic section 20.
The output section 40 is a metal cylindrical rod that is attracted and moved by electromagnetic force, and has the other end facing the electromagnetic coil 50 fixed on the outer shell.
In the electromagnetic coil 50, the electric current is driven by the vibration circuit when a mobile phone arrives, and the output unit 40 applies an external force to the vibration unit 30 at a certain period due to conduction of the periodic current. To provide.
Due to the matching between the external force from the output section 40 and the internal stress and resistance of the elastic section 20 subjected to the vibration of the vibration section 30, the external force acting angular frequency ω of the output section 40 is free It becomes equal to the frequency ωο (ω = ωο), that is, it has a relation of resonance action.
[0006]
When a mobile phone receives a call, the electromagnetic coil 50 is excited with a periodicity, and the output section 40 moves in the compression direction of the elastic section 20, whereby the vibrating section 30 is moved by the elastic section 20. Simultaneously with the above vibration, the vibration of the vibration part 30 can be maintained with less electric power. Each part such as the elastic part 20 continues to transmit power by vibrating operation maintained by the vibrating part 30, and such energy is transmitted to the outer shell 10 and transmitted to the user as vibration. It is.
The output section 40 generates an external force for driving or vibration at the center of the vibration section 30 when the electromagnetic coil 50 is excited. Further, on the vibration part 30, two or more pilot rods 31 are provided, which are arranged parallel to the output direction of the output part 40, and have a smooth surface, In this way, the vibration section 30 can continue the vibration on the elastic section 20 more stably.
[0007]
As described above, the vibration of the vibration section 30 receives the resistance b, and the external force of the output section 40 maintains the vibration of the vibration section 30 on the elastic section 20 with periodicity, The external force angular frequency ω of the output unit 40 becomes equal to the free natural frequency ωο of the elastic unit 20 (ω = ωο), and the vibration quality Qr that controls the vibration unit 30 minimizes the external force energy of the output unit 50. It is consumed in a limited time. The relational expression between the conserved energy and the consumption energy in the process of vibration is
Figure 2004223336
Under the condition that an appropriate material is used, the mass m of the vibrating portion 30 (this mass is the mass obtained by adding the mass of the output portion), the elasticity coefficient k of the elastic portion 20 and the resistance b are obviously increased. In other words, the quality Qr of the vibration can be controlled moderately (or without an excessive increase), and a very effective power saving effect can be achieved.
[0008]
Further, according to the above-described embodiment, the vibrating portion 30 is preferably made of a metal having rigidity or the like. By selecting a material having a considerable stress, it is possible to prevent the deformation from adversely affecting the vibration.
In addition to transmitting the vibration of the vibration part 30 only to the vibration energy on the outer shell, in the embodiment shown in FIG. 3, one fan is provided at each end of the vibration part 30 on the vibration part 30. A pendulum 32 that moves by drawing a pattern is pivoted. The pendulum 32 is made of a material having rigidity, and a hammer head 321 is provided at the other end of the pendulum 32. The pivotal portion of the vibrating portion 30 is located near a support 100 provided on the outer shell 10, and the hammer head 321 causes relative movement by the support of the support 100 (see FIG. 4). In addition, since it collides with the outer shell 10, the vibration effect of the outer shell 10 is further remarkably enhanced. When the hammer head 321 collides with the outer shell 10, the vibration is maintained in a state where power is as small as possible, since the hammer head 321 just hits a position opposite to the vibrating force of the vibrating process of the vibrating part 30, so that excessive resistance is not generated. .
[0009]
Further, as shown in FIG. 5, even if the number of elastic portions 20 provided on the vibrating portion 30 is two or two or more, the same terms as described above can be obtained.
Further, as shown in FIG. 6, the vibration of the vibrating part 30 may be a vibration provided by a pendulum type, and the elastic part 20A is connected to one end of the vibrating part 30A. The vibrating part 30A vibrates in a fan shape by a free frequency inherent in the elastic part 20, and the other end of the vibrating part 30A is provided with an output part 40A made of a magnet or metal drawn by a magnetic force. An electromagnetic coil 50A that is provided corresponding to the direction of the upper vibration and that can generate a magnetic force is provided at a further opposed portion.
In this way, an electric current flows through the electromagnetic coil 50A due to an incoming call of the mobile phone, and a pulling force is provided to the output unit 40A with a periodicity, that is, the pulling force becomes an external force to the vibration unit 30A, and Of the elastic portion 20A can be generated and maintained.
[0010]
