Abstract
The invention discloses a sound performance demonstration device. A sound generator is placed in a sealed tank; one end of a sound sensor is connected with the sound generator and the other end of the sound sensor is connected with a microprocessor and a display device; and a vacuum tank is communicated with the sealed tank by a pipe. In the invention, with the microprocessor and the display device, the frequency and amplitude of the sound generated by the sound generator can be clearly seen; under the vacuumizing action of the vacuum tank, the principle that sound needs a medium for transmission and cannot transmit in vacuum can be demonstrated; and meanwhile, the microprocessor and the display device also display soundless images.
Description
Technical field
But the present invention relates to a kind of device of demonstrating sound performance; Be applicable to physics teaching and experiment field.
Background technology
In physics teaching and experiment, often to explain the key element and the performance thereof of sound.The route of transmission of sound source, sound, sound frequency, tone etc. are demonstrated.At present, apparatus for demonstrating all is single, and neither one is from the device of a plurality of orientation demonstrating sound.
Summary of the invention
The objective of the invention is provides a kind of sound performance demonstration device for overcoming the deficiencies in the prior art, a plurality of key elements that can demonstrating sound.
The technical solution used in the present invention is: place an acoustical generator in one close jar, sound transducer one end connects acoustical generator, and the other end connects microprocessor and display device, and vacuum tank is communicated with close jar by pipeline.
The present invention can clearly see the frequency and the amplitude of the sound that is sent by acoustical generator by microprocessor and display device, by the vacuum tank vacuum action, can demonstrate out sound needs the propagation of media, can't propagate in a vacuum, microprocessor and display device also can not show audiovideo simultaneously.
Description of drawings
Below by the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structure connection layout of the present invention.
Among the figure: 1. microprocessor; 2. pipeline; 3. vacuum tank; 4. close jar; 5. acoustical generator; 6. sound transducer.
Embodiment
As shown in Figure 1, place an acoustical generator 5 in one close jar 4, acoustical generator 5 will be provided with in advance, is arranged to the sound that certain interval of time sends different frequency.Sound transducer 6 one ends connect acoustical generator 5, and the other end connects microprocessor 1 and display device, and vacuum tank 3 is communicated with close jar 4 by pipeline 2.Vacuum tank 3 can be evacuated the air in close jar 4.
Claims (1)
1. sound performance demonstration device, it is characterized in that: in one close jar (4), place an acoustical generator (5), sound transducer (6) one ends connect acoustical generator (5), and the other end connects microprocessor (1) and display device, and vacuum tank (3) is communicated with close jar (4) by pipeline (2).
