Even if the pulverization effect is removed on the article, the medical application is often applied to an organ scan that is not suitable for X-ray irradiation, such as a pregnancy check, or for the drug to be absorbed by the human body more quickly, and the use of ultrasonic transducer The vibration of the device to increase the penetration of human epidermal cells, so that the drug absorption effect is further increased. The existing ultrasonic transducers are mainly divided into a low frequency ultrasonic transducer and a high frequency ultrasonic transducer, and the low frequency ultrasonic transducer is mainly implemented in a large machine such as a washing machine, a motor and a fusion splicer, and medically. The ultrasonic transducer used in medical imaging diagnosis or rehabilitation is usually a frequency-frequency ultrasonic transducer, which is small in size, light in weight, and easy to use in hand. But such a high-frequency ultrasonic transducer is suitable for drugs. The import effect is obviously not good. However, in order to implement the low-frequency ultrasonic transducer for medical purposes, there are still many difficulties in the prior art, such as: the low-frequency ultrasonic transducer requires a relatively high voltage and power for actuation, such as contact with the human body. It is easy to cause burns on the skin. Therefore, the existing low-frequency ultrasonic transducer needs to use a plurality of piezoelectric sheets, and thus a plurality of piezoelectric sheets are arranged, and 1013265501-0 can reduce voltage and power consumption, but This number of piezoelectric sheets is designed to be 98l24l6 (f·single number A〇l〇l page 3/total I4 page 1376246 101 years) resulting in an increase in the volume and weight of the low frequency ultrasonic transducer, not suitable for need to be lightweight It is easy to use for medical use, but if a single piece or a small piece of piezoelectric piece design is used, the voltage must be increased in operation, and the above-mentioned situation which easily causes skin burns in the human body is the case, the inventor has In view of the existing low-frequency ultrasonic transducer, there are disadvantages of using a plurality of piezoelectric sheets to cause heavy bulk and heavy weight, and the use of a single or a small number of piezoelectric sheets is prone to burns and damage to human skin. The invention has been developed for many years in the related fields of manufacturing and design experience and knowledge, and has been developed and improved for the existing low-frequency ultrasonic transducer. [Invention] [0003] The invention relates to a hand-held low-frequency ultrasonic transducer, the main purpose of which is to provide a low-frequency ultrasonic transducer which is light and convenient for hand-held implementation and can concentrate the energy of low-frequency ultrasonic waves, which is generated by using low-frequency ultrasonic waves. The empty six effect, in order to achieve the substantial effect of rapidly introducing the drug into the human body without burning the human skin. In order to achieve the above-mentioned implementation purpose, the inventors have developed the following hand-held low frequency ultrasonic transducer, which includes a front mechanism, a rear mechanism and a piezoelectric sheet; wherein: the front mechanism is such that one end thereof is formed to correspond to the joint portion of the rear mechanism and the joint portion is bundled at the other end of the emitting portion, and the front mechanism is Forming a conical body, the rear mechanism is configured to form a joint at one end thereof to be in contact with the joint portion of the front mechanism and to make the front and rear mechanisms There is a groove between the joints; _ face (Ρ Ρ 1) The piezoelectric piece is accommodated in the groove formed by the front and rear mechanisms.
