Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a hand-held low frequency ultrasonic transducer, and more particularly to a lightweight and portable implementation, and can concentrate the energy of low frequency ultrasonic waves. Low frequency ultrasonic transducer. [Prior Art] [〇〇〇2] Press, ultrasonic transducers are commonly used in industrial and medical applications, such as cleaning, pulverizing, drilling, etc., which is the common supersonic transducer. The oscillating force of the sound wave, in order to achieve the effect of removing impurities on the object, and the medical application is more suitable for organ scanning which is not suitable for X-ray irradiation, such as pregnancy examination, etc., or for the medicine to be absorbed by the human body more quickly. 'The vibration of the ultrasonic transducer is also used to increase the penetration of human epidermal cells, and 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 high-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 used for drug introduction. The 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 in the implementation, thereby setting a plurality of piezoelectric sheets to reduce voltage and power consumption, but the number is large. Piezo Piezo Design, 098124160 Form No. A0101 Page 4 of 15201103596 Causes the increase in volume and weight of the low frequency ultrasonic transducer, not suitable for medical applications that require light and easy holding, but if used A piece or a piece of piezoelectric piece design must increase the voltage in operation, and the above-mentioned situation may cause skin burns. The reason is that the present inventors have the disadvantages of using a plurality of piezoelectric sheets to cause a large volume and a heavy weight, and the use of a single piece or a small piece of the piezoelectric piece is liable to burn the human body in view of the existing low-frequency ultrasonic transducer. The skin and other shortcomings are supplemented by the existing low-frequency ultrasonic transducers in the related fields of manufacturing and design experience and knowledge. The Asian Economics is a multi-faceted thinking. [0003] Ο Updated research and development, and research The present invention relates to a hand-held low-frequency ultrasonic transducer, the main purpose of which is to provide a light weight for hand-held implementation, and a low-frequency ultrasonic wave capable of (four) frequency. Ultra-reading transducer ultrasonic production (four) empty button should be, (four) to quickly take medicine = cell and not burn the physical effect of human skin. Waiting for the human body to meet the purpose of (4) above, this corrective person is researching the wave transducer, which includes the front-end mechanism and the rear-end mechanism, and the rear-end ___ The front mechanism is such that the joint portion thereof and the joint portion facing mechanism form a conical body, and the rear mechanism is configured such that the joint ends of the joints are connected to each other, and The front piece and the front part of the machine are provided with a grooved rear mechanism joint portion 098124160. The piezoelectric piece is accommodated in the front groove formed by the front form 蝙0101, page 5/15, and the rear mechanism. Page 09820441145-0 201103596 Thereby, the piezoelectric sheet can be guided by the cone formed by the pre-mechanism by the low-frequency ultrasonic wave, so that the energy is more concentrated, and accordingly, the lightweight sheet-less piezoelectric sheet of the invention is utilized. It is easy to hold, and can be used to make the low-frequency ultrasonic sound wave of the low-frequency ultrasonic energy, and the speed of the drug is introduced into the human body without causing the actual effect of burning the human skin.
