Description

本発明は、周波数の異なる超音波を重ねて出力することができる固体振動子発振回路、及び、前記固体振動子発振回路を用いた超音波美容器に関する。   The present invention relates to a solid vibrator oscillation circuit capable of outputting ultrasonic waves having different frequencies in an overlapping manner, and an ultrasonic cosmetic device using the solid vibrator oscillation circuit.

近年、皮膚表面に超音波を付与することによって種々の美容効果を与える超音波美容器が普及している。この種の超音波美容器は発振回路の出力端子に圧電セラミックス等の固体振動子を接続し、交流信号（交流電圧）を印加することによって前記固体振動子を振動させ、もって超音波を発生させる仕組みのものが一般的である。   In recent years, ultrasonic cosmetic devices that give various cosmetic effects by applying ultrasonic waves to the skin surface have become widespread. This type of ultrasonic cosmetic device connects a solid vibrator such as piezoelectric ceramics to the output terminal of an oscillation circuit, and vibrates the solid vibrator by applying an AC signal (AC voltage), thereby generating an ultrasonic wave. The one that works is common.

ところで、この種の超音波美容器において用いられる固体振動子には、超音波が効率よく発生する周波数（振動子周波数）がある。この振動子周波数は固体振動子が厚くなるほど小さくなり、固体振動子が薄くなるほど大きくなる。   By the way, the solid vibrator used in this type of ultrasonic cosmetic device has a frequency (vibrator frequency) at which ultrasonic waves are efficiently generated. This vibrator frequency becomes smaller as the solid vibrator becomes thicker and becomes larger as the solid vibrator becomes thinner.

そのため、従来の超音波美容器では、発生させる超音波の周波数に応じて固体振動子の厚さが決定されていた。例えば、肌の美容（例えば、肌の皺やシミ取り、引き締め等）を目的とする超音波美容器では、メガヘルツオーダーの周波数（例えば、１〜５ＭＨｚ）の超音波が発生するように設計されている。   For this reason, in the conventional ultrasonic cosmetic device, the thickness of the solid vibrator is determined according to the frequency of the ultrasonic wave to be generated. For example, an ultrasonic cosmetic device intended for skin beauty (for example, removing wrinkles and spots on skin, tightening, etc.) is designed to generate ultrasonic waves having a frequency on the order of megahertz (for example, 1 to 5 MHz). Yes.

一方、キャビテーション美容器などと称される痩身を目的とする超音波美容器では、キロヘルツオーダーの周波数（例えば、２０〜４０ＫＨｚ）の超音波が発生するように設計されている。   On the other hand, an ultrasonic cosmetic device for slimming, called a cavitation cosmetic device, is designed to generate ultrasonic waves with a frequency in the order of kilohertz (for example, 20 to 40 KHz).

最近では、周波数の異なる複数の超音波を発生させる超音波美容器も開発されている（例えば、下記特許文献１〜２参照。）。   Recently, an ultrasonic cosmetic device that generates a plurality of ultrasonic waves having different frequencies has been developed (see, for example, Patent Documents 1 and 2 below).

特開２００２−２４８１５１号公報JP 2002-248151 A 特開２０１１‐１５５７７６号公報JP 2011-155776 A

しかしながら、前記特許文献１に記載の超音波美顔器は、ヘッドに備えられた複数の超音波振動子（固体振動子）のそれぞれに対し、周波数が異なった発振出力を付与する仕組みを採用しているためヘッドが大型化する。又、複数の固体振動子を用いるため高価格となる。   However, the ultrasonic facial device described in Patent Document 1 employs a mechanism that provides oscillation outputs with different frequencies to each of a plurality of ultrasonic transducers (solid transducers) provided in the head. This increases the size of the head. In addition, since a plurality of solid vibrators are used, the price is high.

一方、前記特許文献２では、単一の圧電体（固体振動子）に厚さを変化させた部分を設けることによって複数の周波数を発生させているため、特殊な形状の固体振動子が必要となる。又、複数の超音波を同時に発生させることができない。   On the other hand, in Patent Document 2, since a plurality of frequencies are generated by providing a single piezoelectric body (solid vibrator) with a portion whose thickness is changed, a solid vibrator having a special shape is required. Become. In addition, a plurality of ultrasonic waves cannot be generated simultaneously.

A first oscillation circuit; and a second oscillation circuit that transmits an AC signal having a frequency different from that of the first AC signal, wherein the solid state oscillator includes the first oscillation circuit and the second oscillation circuit.

What was made into the frequency becomes a preferable aspect.

However, when the frequency of the AC signal generated from the first oscillation circuit 3 is in the megahertz order, the frequency of the AC signal generated from the second oscillation circuit 4 is in the order of kilohertz (more preferably, 20 to 40 KHz). It is preferable that

なお、本実施形態においては、前記第一発振回路３と前記第二発振回路４とを直列に接続することによって多重発振回路５を構築しているが、前記第一発振回路３から発生される交流信号の周波数と、前記第二発振回路４から発生される交流信号の周波数とが異なるため、前記多重発振回路５の構築にあたっては、前記固体振動子２のインピーダンスに応じて、巻き数の調整を行うことが好ましい。   In the present embodiment, the multiple oscillation circuit 5 is constructed by connecting the first oscillation circuit 3 and the second oscillation circuit 4 in series, but is generated from the first oscillation circuit 3. Since the frequency of the AC signal is different from the frequency of the AC signal generated from the second oscillation circuit 4, the number of turns is adjusted according to the impedance of the solid-state vibrator 2 when constructing the multiple oscillation circuit 5. It is preferable to carry out.
