Abstract
The utility model discloses an efficient low-frequency vibrating source whose energy conversion is finished with piezoelectric ceramics sheets and whose working power supply adopts ordinary commercial alternating current. The utility model which has the advantages of high efficiency, light weight and low cost can be used in various vibration occasions or be made into various vibrating toys, bells, infrasonic wave generators, etc.
Description
The utility model is about the low-frequency vibration source, and is particularly low-cost, the utility model of high efficiency vibration source.
Present vibration source adopts electromagnetic type, and this mode of vibration efficient is low, needs a large amount of copper materials, because self is heavy, purposes is restricted.
The purpose of this utility model, be for provide a kind of efficient height, in light weight, cost is low, the low-frequency vibration source that purposes is wide.
Its scheme is to utilize the expansion performance of piezoelectric ceramic piece under action of alternative electric field, the formation power conversion.
Figure, the 1st, line map, 220 volts of 50 hertz of electric mains are added to piezoelectric ceramic piece HOL the two poles of the earth by protective resistance R, make it to be formed on stretching under the alternating electric field.Behind the shaker arm of fixing thin elastic sheet metal making on the base plate at piezoelectric ceramic piece, also resonance with it of the flexible excited vibrational arm vibration of the electricity of piezoelectric ceramic piece becomes mechanical oscillation consumingly.During actual the use, can select or make different area and substrate thickness or difform piezoelectric ceramic piece according to purposes.The resistance of resistance R is being chosen more than 1 kilo-ohm as required.The utility model can be used for various vibration occasions, can save a large amount of copper materials and the energy.
Figure, the 2nd is applied to a kind of example of the high bass electric bell of percussive, piezoelectric ceramic piece 1 is fixed on the base plate 6 through bracing frame 5, shaker arm 2 is fixed on the substrate of piezoelectric ceramics, its top is percussive hammer 7 fixedly, 3, the 4th, a pair of high bass bell, to the piezoelectric ceramics two ends, device just sends melodious double-tone the tinkle of bells through 5 kilo-ohms of resistance for 220 volts of civil powers.
Figure, the 3rd is used for the example of infrasonic wave generator, and shaker arm replaces with a thin razor blade 2, the 3rd, bracing frame, when 220 volts civil powers when 20 kilo-ohms of resistance add on the piezoelectric ceramic piece 1,2 just vibrate the generation infrasound.
Claims (2)
1. low frequency high-efficiency vibration source; be connected to piezoelectric ceramic piece HOL greater than 1 kilo-ohm protective resistance R; several shaker arms are fixed on the substrate of piezoelectric ceramic piece, it is characterized in that: 220 volts of 50 hertz of civil powers are directly as the working power of piezoelectric ceramic piece.
2. according to the described low frequency high-efficiency vibration of claim 1 source, it is characterized in that: shaker arm is to make with resilient metal material.
