Abstract

The utility model provides a vibrating table which vibrates following the music rhythm, and comprises a vibrating plate, a loud-speaker, and a control circuit. The vibrating table is characterized in that the control circuit comprises a low pass filter, a preamplifier, a reshape diode, and a power amplifier, while an electrical signal which is amplified by the power amplifier is directly input into the loud-speaker. The vibrating table can be applied to stages, song and dance halls, and screen and video projecting halls. The vibrating plate of the vibrating table generates the vibration in company with the drum rhythm of the music and the sound in the story, when the people stand (sit) on the vibrating plate, a strong sense of rhythm and strong perception of personally on the scene can be obtained. When the utility model is used as the health care apparatus in sanatoriums and hospitals, the vibrating table can make the people accepting the health care carry out the systemic vibrating massage along with listening to the music.

Description

Vibration machine

The utility model relates to a kind of vibration machine with music rhythm vibration, is mainly used in stage, dancing hall, film and television and puts the shadow Room, sanatorium, hospital and play amusement and health-care effect.

The surround speaker that present some video display are put the shadow Room, stage, dancing hall is given certain impression on the spot in person, but is a kind of auditory perception, and the audio frequency vibration that this class audio amplifier is produced can not cause the vibration of human body, so impression on the spot in person is not very strong.In addition, existing a kind of vibromassage pad, its structure is that battery is that the two poles of the earth of power supply connect a sheet metal and one group of spring respectively, and sheet metal and spring are separately fixed at by (seat) pad two ends, thus the formation certain distance, when the people leans on (seat) on the vibromassage pad, sheet metal is extruded into spring and contacts, circuit turn-on, thus produce vibration, human body is carried out vibromassage, play a role in health care.This vibromassage pad only carries out part massage to the human body contact by (seat) pad position, can't make whole health vibration, and this vibromassage is very mechanical, lacks enjoyment.

The purpose of this utility model is to provide a kind of and can vibrates with music rhythm, be applied in stage, video display are put human body are vibrated with the music rhythm and the plot sound, be applied in make in the health care people when listening to the music whole body by the vibration machine of vibromassage.

Solution of the present utility model is: a kind of vibration machine, form by electrical loudspeaker and control circuit that oscillating plate, oscillating plate are fixing down, be characterized in that control circuit is by the low pass filter with the signal of telecommunication high frequency waves filtering of radio-cassette player or microphone output, low pass filter is exported the preamplifier that the signal of telecommunication carries out preposition amplification, the shaping diode of latter linked two reversal connections in parallel of preamplifier and the power amplifier formation of after shaping, carrying out power amplification, the output signal of telecommunication input loud speaker of power amplifier.The waveform that audio signal is exported to the signal of telecommunication of vibration machine from radio-cassette player and microphone is at low frequency signal many high-frequency signals that superposeed, by behind the low pass filter with the high-frequency signal filtering, carry out preposition amplification then; In the low frequency signal that amplifies, many small amplitude waves are arranged,, small amplitude wave is eliminated, amplify through power amplifier then, directly import in the loud speaker by the diode shaping of two reversal connections in parallel.Directly enter loud speaker after the ripple amplification than large amplitude, make loud speaker with low-frequency vibration.For the vibratory output that makes oscillating plate is enough big, can on oscillating plate, fix a plurality of loud speakers.

The utility model has the advantages that: control circuit elimination of the present utility model high-frequency signal and little amplitude signal ripple, corresponding audio signal, the rich happy sound of bass will make the vibration machine vibration.This vibration machine is used in stage, the dancing hall, can be along with the drumbeat of music, and vibration machine produces vibration, and the people stands in the timing that can feel very strong above the oscillating plate.Be applied in video display and put in the shadow Room, vibration machine can produce vibration along with the music and the sound in the plot of richness, and people's seat can change the generation vibration along with the sound of the story of a play or opera on oscillating plate, strengthened impression on the spot in person greatly.Be applied in sanatorium, hospital when doing health care, on one side can listen to the music, Yi Bian carry out the vibromassage of whole body.

The utility model can further specify in conjunction with the accompanying drawings.

Fig. 1 is the utility model control circuit block diagram;

Fig. 2 is the utility model embodiment circuit diagram Figure of abstract of holding concurrently.

The utility model embodiment control circuit as shown in Figure 2, the signal of telecommunication is by resistance (R1, R2) decay, low pass filter filters out high-frequency signal by constituting after diode (V1, the V2) constant voltage by two filters (D1, D2), after preamplifier D3 amplifies, two diodes (V7, V8) shaping by reversal connection in parallel, amplify among the input row loud speaker RL by power amplifier D4 then, wherein two filters (D1, D2) and preamplifier D3 adopt the LN324 integrated package, and power amplifier D4 adopts SHN110 II integrated package.In this circuit, connect once V4, V5, three triode three utmost points of V6 and amplify the display circuit that back demonstration power amplification driving signal in luminous tube V3 is sent out power, display circuit extracts the filtered signal of telecommunication of low pass filter, display circuit shows vibration strong or weak by receiving light pipe, thereby the resistance of scalable W2 is with regulatory work rate amplifier power.
