Description

本発明は、超音波振動素子を固着させてあるプローブヘッドを肌に接触させて用いる超音波美容器に関するものである。   The present invention relates to an ultrasonic cosmetic device that uses a probe head to which an ultrasonic vibration element is fixed in contact with the skin.

従来から、超音波振動素子を用いてプローブヘッドを超音波振動させ、このプローブヘッドを肌に当てることで肌の引締め効果等の様々な美容効果を得ることができる超音波美容器が知られている（特許文献１参照）。   Conventionally, there has been known an ultrasonic cosmetic device that can obtain various cosmetic effects such as a skin tightening effect by ultrasonically vibrating a probe head using an ultrasonic vibration element and applying the probe head to the skin. (See Patent Document 1).

上記超音波美容器のプローブヘッド１や超音波振動素子２は図３、図４に示すようなものであり、その外底面１ａを肌接触面４とする有底筒状のプローブヘッド１の内底面１ｂに、該内底面１ｂよりも僅かに小径の円板状を成す超音波振動素子２を固着させた構造となっている。そして、この超音波振動素子２に、一端側を超音波発振回路（図示せず）に接続させたリード線３の他端側を半田３０にて接合させ、更に補強用接着剤３１を施すことで、超音波発振回路から出力される電気信号を超音波振動素子２にまで伝達させて超音波振動を発生させるものである。   The probe head 1 and the ultrasonic vibration element 2 of the ultrasonic cosmetic device are as shown in FIGS. 3 and 4, and the inside of the bottomed cylindrical probe head 1 whose outer bottom surface 1 a is the skin contact surface 4. The ultrasonic vibration element 2 having a disk shape slightly smaller in diameter than the inner bottom surface 1b is fixed to the bottom surface 1b. Then, the other end side of the lead wire 3 whose one end side is connected to the ultrasonic oscillation circuit (not shown) is joined to the ultrasonic vibration element 2 with the solder 30, and the reinforcing adhesive 31 is further applied. Thus, an electrical signal output from the ultrasonic oscillation circuit is transmitted to the ultrasonic vibration element 2 to generate ultrasonic vibration.

しかしながら上記超音波美容器にあっては、超音波振動素子２とリード線３とを半田３０で接合させる構造であるために、量産工程中にて半田３０の量や位置にばらつきが生じ、このばらつきの存在に起因して超音波振動素子２の超音波振動にばらつきが生じてしまうという問題があった。   However, since the ultrasonic cosmetic device has a structure in which the ultrasonic vibration element 2 and the lead wire 3 are joined by the solder 30, the amount and position of the solder 30 vary during the mass production process. There is a problem that the ultrasonic vibration of the ultrasonic vibration element 2 varies due to the presence of the variation.

また、上記超音波振動素子２はその両端面２ａ，２ｂを異なる電極に設定して超音波振動を発生させるものであるが、両端面２ａ，２ｂのうち一方の端面２ａはプローブヘッド１に固着されるため、該端面２ａ側の電極を他方の端面２ｂにまで一部折返して露出させるとともに、この露出させて成る折返し電極３２にリード線３を接合させる構造としている。即ち、上記超音波振動素子２にあっては、露出側の端面２ｂの一部に該端面２ｂ側の電極とは異極の折返し電極３２が存在する構造であり、したがって折返し電極３２を設けてある部分においては超音波振動を発生させることができず効率が悪いという問題がある。
特開平１１−３７４号公報 The ultrasonic vibration element 2 generates ultrasonic vibrations by setting both end surfaces 2a and 2b to different electrodes. One end surface 2a of the both end surfaces 2a and 2b is fixed to the probe head 1. Therefore, the electrode on the side of the end surface 2a is partially folded back to the other end surface 2b and exposed, and the lead wire 3 is joined to the folded electrode 32 that is exposed. That is, the ultrasonic vibration element 2 has a structure in which the folded electrode 32 having a different polarity from the electrode on the end surface 2b side exists in a part of the exposed end surface 2b. There is a problem that the ultrasonic vibration cannot be generated in a certain portion and the efficiency is low.
Japanese Patent Laid-Open No. 11-374

本発明は上記問題点に鑑みて発明したものであって、超音波振動のばらつきが少なく、また高効率で超音波振動を発生させることの可能な超音波美容器を提供することを課題とするものである。   The present invention has been invented in view of the above problems, and an object of the present invention is to provide an ultrasonic cosmetic device that is capable of generating ultrasonic vibration with high efficiency with little variation in ultrasonic vibration. Is.

上記課題を解決するために本発明を、外底面１ａが肌接触面４となるように導電性材料で有底筒状に形成したプローブヘッド１と、有底筒状のプローブヘッド１の内底面１ｂに固着される超音波振動素子２と、超音波振動素子２を超音波振動させる為の電気信号を出力する超音波発振回路１０とを具備した超音波美容器において、プローブヘッド１よりも小径の有底筒状を成す支持部材８を、該支持部材８の外底面８ａが超音波振動子２の端面２ｂと所定距離を介して対向し、且つ、該支持部材８の側周壁８ｂの外面がプローブヘッド１の側周壁１ｃの内面と所定距離を介して対向するように配置し、超音波振動素子２のプローブヘッド１に固着される側の端面２ａと、該端面２ａの反対側の端面２ｂとを異極に設定し、超音波発振回路１０から出力される電気信号の一方の極を伝達させる為の金属弾性体１３を、支持部材８の側周壁８ｂに配置してプローブヘッド１に弾接させ、超音波発振回路１０から出力される電気信号の他方の極を伝達させる為の金属弾性体１２を、支持部材８の底壁に配置して超音波振動素子２のプローブヘッド１に固着される側の端面２ａと反対側の端面２ａに弾接させたものとする。このようにすることで、超音波振動素子２をリード線に半田接合させる必要が無く、したがって、半田の量や位置のばらつきに起因して超音波振動素子２の超音波振動にばらつきが生じるといった問題が生じない。 In order to solve the above problems, the present invention is based on the probe head 1 formed in a bottomed cylindrical shape with a conductive material so that the outer bottom surface 1a becomes the skin contact surface 4, and the inner bottom surface of the bottomed cylindrical probe head 1 In an ultrasonic cosmetic device including an ultrasonic vibration element 2 fixed to 1 b and an ultrasonic oscillation circuit 10 that outputs an electric signal for ultrasonic vibration of the ultrasonic vibration element 2, the diameter is smaller than that of the probe head 1. The outer bottom surface 8a of the support member 8 is opposed to the end surface 2b of the ultrasonic transducer 2 through a predetermined distance, and the outer surface of the side peripheral wall 8b of the support member 8 Is disposed so as to face the inner surface of the side peripheral wall 1c of the probe head 1 through a predetermined distance, and an end surface 2a of the ultrasonic vibration element 2 fixed to the probe head 1 and an end surface opposite to the end surface 2a 2b is set to a different polarity, and the ultrasonic oscillation circuit 10 The metal elastic body 13 for transmitting one pole of the electric signal output from the ultrasonic wave is arranged on the side peripheral wall 8b of the support member 8 and brought into elastic contact with the probe head 1, and is output from the ultrasonic oscillation circuit 10. A metal elastic body 12 for transmitting the other pole of the signal is disposed on the bottom wall of the support member 8 and is placed on the end face 2a opposite to the end face 2a of the ultrasonic vibration element 2 fixed to the probe head 1. Assume that they have been in contact with each other. By doing so, there is no need to solder the ultrasonic vibration element 2 to the lead wire, and accordingly, the ultrasonic vibration of the ultrasonic vibration element 2 varies due to variations in the amount and position of the solder. There is no problem.

また、上記構成の超音波美容器にあっては、超音波振動素子２の両面２ａ，２ｂを全面において異極に設定することができる。これにより、超音波振動素子２全体で超音波振動を発生させ、高効率での超音波振動を実現することが可能となる。加えて、金属弾性体１３を弾接させてプローブヘッド１に電気信号を伝達させる構成としたことで、半田接合させ難い材質であるアルミニウム等を用いてプローブヘッド１を形成することが可能となる。アルミニウムを用いた場合にはプローブヘッド１を複雑な形状に加工し易く、したがってプローブヘッド１を使用者にとって使い易い形状に設けることが可能となる。 Further, in the ultrasonic cosmetic device having the above structure, it is possible to set both surfaces 2a of the ultrasonic transducer elements 2 and 2b on opposite poles in the entire surface. Thereby, it is possible to generate ultrasonic vibration in the entire ultrasonic vibration element 2 and realize ultrasonic vibration with high efficiency. In addition, since the metal elastic body 13 is elastically contacted to transmit an electrical signal to the probe head 1, the probe head 1 can be formed using aluminum or the like that is difficult to solder. . When aluminum is used, the probe head 1 can be easily processed into a complicated shape, and therefore the probe head 1 can be provided in a shape that is easy for the user to use.

また、上記構成の超音波美容器において、超音波振動素子２と金属弾性体１２との接触個所を、超音波振動素子２の外周縁近傍に設けることも好ましい。超音波振動素子２の外周縁部近傍は超音波振動の影響を受け難い箇所であるから、このようにすることで高い接触信頼性により超音波振動素子２に電気信号を効率良く伝達して、高効率での超音波振動を実現することが可能となる。   In the ultrasonic cosmetic device having the above-described configuration, it is also preferable to provide a contact portion between the ultrasonic vibration element 2 and the metal elastic body 12 in the vicinity of the outer peripheral edge of the ultrasonic vibration element 2. Since the vicinity of the outer peripheral edge of the ultrasonic vibration element 2 is a portion that is not easily affected by ultrasonic vibration, an electrical signal is efficiently transmitted to the ultrasonic vibration element 2 with high contact reliability by doing in this way, It is possible to realize ultrasonic vibration with high efficiency.

また、超音波振動子２に弾接させる金属弾性体１３を、略円形状を成す接触面を介して電気信号を伝達させるものとすることも好ましい。このようにすることで、超音波振動素子２との接触面が大きく且つ超音波振動の影響を受け難い形態となり、これにより超音波振動素子２に電気信号を効率良く伝達して、高効率での超音波振動を実現することが可能となる。 Further, the elastic metal body 1 3 to contact the ultrasonic transducer 2 elastically, it is also preferable to those for transmitting electrical signals via a contact surface having a substantially circular shape. By doing so, the contact surface with the ultrasonic vibration element 2 is large and is not easily affected by the ultrasonic vibration, whereby an electric signal is efficiently transmitted to the ultrasonic vibration element 2 with high efficiency. It is possible to realize the ultrasonic vibration.

なお、以上述べた各構成は、本発明の趣旨を逸脱しない限り適宜組合せ可能である。   Each configuration described above can be appropriately combined without departing from the gist of the present invention.

本発明は、超音波振動のばらつきが少なく、また高効率で超音波振動を発生させることの可能な超音波美容器を提供することができるという効果を奏する。   The present invention has an effect that it is possible to provide an ultrasonic cosmetic device that has little variation in ultrasonic vibrations and can generate ultrasonic vibrations with high efficiency.

以下、本発明を添付図面に示す実施形態に基いて説明する。なお、本発明の構成のうち、背景技術にて既述した構成と同様の構成については同一符号を付して詳細な説明を省略する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. Of the configurations of the present invention, configurations similar to those already described in the background art are assigned the same reference numerals, and detailed description thereof is omitted.

図１には、本発明の実施形態における一例の超音波美容器を示している。本例の超音波美容器の外殻を成す本体ハウジング５は、正面側及び背面側の半割ハウジング５ａ，５ｂから成り、片手で把持可能な形状に形成されている。正面側の半割ハウジング５ａの中央部分には操作スイッチ６を突没自在に設けており、該半割ハウジング５ａの先端部にはヘッド取付部７を円形状に開口させている。超音波振動素子２を超音波振動させる為の電気信号を出力する超音波発振回路１０は、一対の半割ハウジング５ａ，５ｂを嵌合させてビス等の固着具１５で固定する際に両半割ハウジング５ａ，５ｂに挟持されて本体ハウジング５内に収納されるものであり、操作スイッチ６の突没動作に応じて電気信号を出力するようになっている。なお、図中の符号９は電源供給用のＤＣジャックである。   FIG. 1 shows an example of an ultrasonic cosmetic device according to an embodiment of the present invention. The main body housing 5 forming the outer shell of the ultrasonic cosmetic device of this example is composed of front and rear half housings 5a and 5b, and is formed in a shape that can be held with one hand. An operation switch 6 is provided so as to protrude and retract at the center of the front half housing 5a, and a head mounting portion 7 is opened in a circular shape at the tip of the half housing 5a. The ultrasonic oscillation circuit 10 that outputs an electric signal for ultrasonically vibrating the ultrasonic vibration element 2 is configured such that when the pair of half housings 5a and 5b are fitted and fixed with a fixing tool 15 such as a screw, both halves are arranged. It is sandwiched between the split housings 5a and 5b and housed in the main body housing 5, and an electrical signal is output in accordance with the projecting and retracting operation of the operation switch 6. Reference numeral 9 in the figure is a DC jack for supplying power.

プローブヘッド１は、アルミニウム等の高導電性の金属材料を用いて有底筒状に形成され、その外底面１ａである肌接触面４が外部に突出して露出するように、正面側の半割ハウジング５ａの上記ヘッド取付部７内に装着される。プローブヘッド１の肌接触面４との反対側の面である内底面１ａには、超音波振動素子２が導電性の高い状態で固着されている。上記超音波振動素子２は、そのプローブヘッド１に固着される側の端面２ａ全体と、該端面２ａと反対側の端面２ｂ全体とを、異極に設定したものである。   The probe head 1 is formed in a bottomed cylindrical shape using a highly conductive metal material such as aluminum, and the front side halves so that the skin contact surface 4 as the outer bottom surface 1a protrudes to the outside and is exposed. It is mounted in the head mounting portion 7 of the housing 5a. The ultrasonic vibration element 2 is fixed to the inner bottom surface 1a, which is the surface opposite to the skin contact surface 4 of the probe head 1, in a highly conductive state. In the ultrasonic vibration element 2, the entire end surface 2a fixed to the probe head 1 and the entire end surface 2b opposite to the end surface 2a are set to have different polarities.

上記有底筒状を成すプローブヘッド１内には、プローブヘッド１よりも小径の有底筒状を成す合成樹脂製の支持部材８を、その外底面８ａがプローブヘッド１の内底面１ｂや超音波振動素子２の端面２ｂと所定の隙間を介して対向し、且つその側周壁８ｂの外面がプローブヘッド１の側周壁１ｃの内面と所定の隙間を介して対向するように配置している。プローブヘッド１の側周壁１ｃ先端からは外方に向けてフランジ部１ｄを延設しており、また支持部材８においてもその側周壁８ｂの先端から外方に向けてフランジ部８ｃを延設しており、半割ハウジング５ａ，５ｂによりフランジ部１ｄ，８ｃを挟持させることで、プローブヘッド１及び支持部材８を上記配置にて固定している。なお、図中の符号１１は、プローブヘッド１の側周壁１ｃ外面と半割ハウジング５ａのヘッド取付部７内面との間に介在してヘッド取付部７から本体ハウジング５内に水分等が侵入することを防止するＯリングである。   In the probe head 1 having the bottomed cylindrical shape, a synthetic resin supporting member 8 having a bottomed cylindrical shape having a diameter smaller than that of the probe head 1 is disposed. The acoustic vibration element 2 is disposed so as to face the end surface 2b with a predetermined gap, and the outer surface of the side peripheral wall 8b faces the inner surface of the side peripheral wall 1c of the probe head 1 with a predetermined gap. A flange portion 1d extends outward from the distal end of the side peripheral wall 1c of the probe head 1, and the flange portion 8c extends outward from the distal end of the side peripheral wall 8b of the support member 8 as well. The probe head 1 and the support member 8 are fixed in the above-described arrangement by sandwiching the flange portions 1d and 8c by the half housings 5a and 5b. Reference numeral 11 in the drawing is interposed between the outer surface of the side peripheral wall 1c of the probe head 1 and the inner surface of the head mounting portion 7 of the half housing 5a so that moisture and the like enter the main body housing 5 from the head mounting portion 7. This is an O-ring that prevents this.

支持部材８の外底面８ａには、高伝導性の金属材料から成る金属弾性体１２をビス等の固着具１４で固定している。この金属弾性体１２は、上記固定状態において超音波振動素子２と弾接する複数の接触片１２ａと、上記固定状態において支持部材８の外底面８ａに設けてある開口部（図示せず）から背面側に突出してリード線３（３ａ）と電気的に接続される接続片（図示せず）とを延設したものである。   A metal elastic body 12 made of a highly conductive metal material is fixed to the outer bottom surface 8a of the support member 8 with a fixing tool 14 such as a screw. The metal elastic body 12 includes a plurality of contact pieces 12a elastically contacting the ultrasonic vibration element 2 in the fixed state, and an opening (not shown) provided on the outer bottom surface 8a of the support member 8 in the fixed state. A connecting piece (not shown) that protrudes to the side and is electrically connected to the lead wire 3 (3a) is extended.

また、支持部材８の側周壁８ｂには、上記金属弾性体１２と同様の高伝導性の金属材料から成る金属弾性体１３を、圧入等の固定手段により固定している。この金属弾性体１３は、上記固定状態においてプローブヘッド１の側周壁１ｃの内面と弾接する複数の接触片１３ａと、上記固定状態において支持部材８に設けてある開口部８ｃから背面側に突出してリード線３（３ｂ）と電気的に接続される接続片１３ｂとを延設したものである。   A metal elastic body 13 made of a highly conductive metal material similar to the metal elastic body 12 is fixed to the side peripheral wall 8b of the support member 8 by a fixing means such as press fitting. The metal elastic body 13 projects to the back side from a plurality of contact pieces 13a that elastically contact the inner surface of the side peripheral wall 1c of the probe head 1 in the fixed state and the opening 8c provided in the support member 8 in the fixed state. A connecting piece 13b that is electrically connected to the lead wire 3 (3b) is extended.

ここで、超音波振動素子２と弾接される側の金属弾性体１２に接続されるリード線３ａは、超音波発振回路１０から出力される電気信号の一方の極を伝達させるものであり、プローブヘッド１と弾接される側の金属弾性体１３に接続されるリード線３ｂは、上記電気信号の他方の極を伝達させるものである。即ち、超音波振動素子２接触側の金属弾性体１２と、プローブヘッド１接触側の金属弾性体１３とは、上記電気信号の互いに異極側をそれぞれ超音波振動素子２やプローブヘッド１に伝達するものであり、金属弾性体１２側に伝達された電気信号が超音波振動素子２の固着側と反対の端面２ｂにまで伝達されるとともに、プローブヘッド１に伝達された電気信号は該プローブヘッド１内を伝達されて超音波振動素子２の固着側の端面２ａにまで伝達される構造になっている。   Here, the lead wire 3a connected to the metal elastic body 12 on the side elastically contacted with the ultrasonic vibration element 2 transmits one pole of the electric signal output from the ultrasonic oscillation circuit 10, The lead wire 3b connected to the metal elastic body 13 on the side elastically contacted with the probe head 1 transmits the other pole of the electric signal. That is, the metal elastic body 12 on the contact side of the ultrasonic vibration element 2 and the metal elastic body 13 on the contact side of the probe head 1 transmit the opposite polar sides of the electric signal to the ultrasonic vibration element 2 and the probe head 1, respectively. The electrical signal transmitted to the metal elastic body 12 side is transmitted to the end surface 2b opposite to the fixing side of the ultrasonic vibration element 2, and the electrical signal transmitted to the probe head 1 is transmitted to the probe head. 1 is transmitted to the end face 2 a on the fixing side of the ultrasonic vibration element 2.

しかして、上記構成の超音波美容器において操作スイッチ６をオンして超音波発振回路１０から電気信号を出力させると、該電気信号の一方の極がリード線３ａ及び金属弾性体１２を介して超音波振動素子２の一方の端面２ｂに伝達されるとともに、該電気信号の他方の極がリード線３ｂ、金属弾性体１３、プローブヘッド１を介して超音波振動素子２の他方の端面２ａにまで伝達される。超音波振動素子２は、一方の端面２ｂ側の全面と、他方の端面２ａ側の全面とを異極に設定しているので、該超音波振動素子２全体で超音波振動が発生するものであり、したがって超音波振動を高効率で発生させることが可能となっている。   Accordingly, when the operation switch 6 is turned on and an electric signal is output from the ultrasonic oscillation circuit 10 in the ultrasonic cosmetic device having the above-described configuration, one pole of the electric signal passes through the lead wire 3 a and the metal elastic body 12. While being transmitted to one end face 2 b of the ultrasonic vibration element 2, the other pole of the electric signal is transferred to the other end face 2 a of the ultrasonic vibration element 2 via the lead wire 3 b, the metal elastic body 13, and the probe head 1. Is transmitted. Since the ultrasonic vibration element 2 is set so that the entire surface on the one end face 2b side and the entire surface on the other end face 2a side have different polarities, ultrasonic vibration is generated in the entire ultrasonic vibration element 2. Therefore, it is possible to generate ultrasonic vibration with high efficiency.

また、超音波振動素子２に金属弾性体１２を介して電気信号を伝達させる構造としているので、従来のように超音波振動素子２とリード線３ａとを半田接合させる必要が無く、半田の量や位置のばらつきに起因して超音波振動にばらつきが生じるといった問題がない。加えて、本例のようにプローブヘッド１に電気信号を伝達させようとした場合に、プローブヘッド１とリード線３ｂとを半田接合させる構造であれば該プローブヘッド１の材質として半田接合させ易い材質を選択する必要があるが、プローブヘッド１とリード線３ｂとの間に金属弾性体１３を介在させて電気信号を伝達させる構造とすることで、半田接合させ難い材質であるアルミニウム等を用いてプローブヘッド１を形成することが可能である。アルミニウムを用いた場合にはプローブヘッド１を複雑な形状に加工し易く、したがってプローブヘッド１を使用者にとって使い易い形状に設けることが可能である。   In addition, since an electrical signal is transmitted to the ultrasonic vibration element 2 via the metal elastic body 12, there is no need to solder the ultrasonic vibration element 2 and the lead wire 3a as in the prior art, and the amount of solder There is no problem that the ultrasonic vibration varies due to variations in position and position. In addition, when an electrical signal is transmitted to the probe head 1 as in this example, if the probe head 1 and the lead wire 3b are joined together by solder, the probe head 1 can be easily soldered as a material. Although it is necessary to select a material, aluminum or the like which is difficult to solder is used by adopting a structure in which an electric signal is transmitted by interposing a metal elastic body 13 between the probe head 1 and the lead wire 3b. Thus, the probe head 1 can be formed. When aluminum is used, the probe head 1 can be easily processed into a complicated shape, and therefore the probe head 1 can be provided in a shape that is easy for the user to use.

なお、本例においては金属弾性体１２の接触片１２ａを、超音波振動素子２の円形状を成す端面２ａの中でも超音波振動の影響を受け難い箇所である外周縁近傍の個所に接触するように設けているので、高い接触信頼性により超音波振動素子２に電気信号を効率良く伝達して、高効率で超音波振動を発生させることが可能になっている。   In this example, the contact piece 12a of the metal elastic body 12 is brought into contact with a portion in the vicinity of the outer peripheral edge that is hardly affected by the ultrasonic vibration among the circular end face 2a of the ultrasonic vibration element 2. Therefore, it is possible to efficiently transmit an electric signal to the ultrasonic vibration element 2 with high contact reliability and generate ultrasonic vibration with high efficiency.

図２には、本発明の実施形態における他例の超音波美容器の主要部を示している。なお、本例の構成のうち、既述した一例と同様の構成については同一符号を付して詳細な説明を省略する。   In FIG. 2, the principal part of the ultrasonic cosmetics device of the other example in embodiment of this invention is shown. Note that, in the configuration of this example, the same reference numerals are given to the same configurations as the above-described example, and detailed description thereof is omitted.

本例においては、超音波振動素子２のプローブヘッド１に固着される側の端面２ａとは反対側の端面２ｂと、支持部材８の外底面８ａとの間に、高伝導性の金属材料から成るコイルばね２０を圧縮状態で介在させており、このコイルばね２０を、超音波振動素子２に弾接される金属弾性体１３としている。上記コイルばね２０は、支持部材８に形成した開口部８ｄから背面側に突出するように設けた延長端部２０ａにおいてリード線３ａと電気的に接続されものであり、延長端部２０ａを設けた側と逆側の端部２０ｂにおいて超音波振動素子２と接触するように設けている。コイルばね２０と超音波振動素子２との接触面は、超音波振動素子２の円形状を成す端面２ｂの外周縁近傍に略円形状に形成されるものであり、このように、超音波振動素子２の超音波振動の影響を受け難い箇所に略円形状を成すように大きな面積で形成される接触面を介して電気信号が伝達されるように設けることで、高い接触信頼性により超音波振動素子２に電気信号を効率良く伝達して更に高効率で超音波振動を発生させることが可能になっている。   In this example, a highly conductive metal material is used between the end surface 2 b opposite to the end surface 2 a fixed to the probe head 1 of the ultrasonic vibration element 2 and the outer bottom surface 8 a of the support member 8. The coil spring 20 is interposed in a compressed state, and the coil spring 20 is a metal elastic body 13 that is elastically contacted with the ultrasonic vibration element 2. The coil spring 20 is electrically connected to the lead wire 3a at the extended end 20a provided so as to protrude from the opening 8d formed in the support member 8 to the back side, and the extended end 20a is provided. It is provided so as to be in contact with the ultrasonic vibration element 2 at the end 20b opposite to the side. The contact surface between the coil spring 20 and the ultrasonic vibration element 2 is formed in a substantially circular shape in the vicinity of the outer peripheral edge of the end face 2b forming the circular shape of the ultrasonic vibration element 2, and thus the ultrasonic vibration By providing an electrical signal to be transmitted through a contact surface formed in a large area so as to form a substantially circular shape at a location that is not easily affected by the ultrasonic vibration of the element 2, the ultrasonic wave can be transmitted with high contact reliability. It is possible to efficiently transmit an electric signal to the vibration element 2 to generate ultrasonic vibration with higher efficiency.
