Abstract
The utility model discloses a vibrating sound generating demonstrator, which belongs to the technical field of teaching instruments, and mainly comprises a base, an electromagnet, a contact chip, a spring lamination, a vibrating piece and a fixing screw, a amplitude display screen, a voltage-stabilized power supply (transformer), and an electric power plug etc. The whole apparatus is switched on, the electromagnet generates magnetism to absorb the contact chip and makes the spring lamination drive the vibrating piece swing left and right, thereby making sounds, at the same time, the amplitude display screen can show size of the amplitude clearly; switched off, the magnism disappears, the vibration stops, the sound disappears, and the vibrating piece stops swinging. The utility model is scientific, novel and practical; the usage is convenient, the production is simple and the demonstration effect is good.
Description
Technical field
The utility model belongs to instruments used for education facility technology field, is specifically related to a kind of vibration sounding apparatus for demonstrating.
Background technology
At present the analog vibration sounding lecture experiment of being done in the teaching is by knocking object, thereby object is sounded reach teaching purpose.Also there is not a kind of instrument to possess simultaneously: the function of vibration, sounding, demonstration amplitude size.
Summary of the invention
The purpose of this utility model is that a kind of can doing of design vibrated sonorific simulation demonstrating apparatus.
This device utilizes the electromagnet principle design to form, and has science, novelty, practicality, and is easy to use, makes simple, good demonstration effect.
The utility model is achieved like this: it mainly comprises base, electromagnet, contact chip, spring leaf, vibrating reed and fixed screw, amplitude display screen, stabilized voltage supply (transformer), compositions such as attaching plug.It is characterized in that it comprises base and amplitude display screen, be provided with stabilized voltage supply and attaching plug in the base, the vibrating reed that power supply is connected with electromagnet, contact chip, spring leaf and can swings in the amplitude display screen.
Description of drawings
Accompanying drawing 1 is the structural representation sketch of the utility model embodiment.
In the accompanying drawing, 1 is the amplitude display screen, and 2 is vibrating reed, and 3 is electromagnet, and 4 is spring leaf, and 5 is contact chip, and 6 is stabilized voltage supply, and 7 is attaching plug.
Embodiment
Whole device energized in the present embodiment, electromagnet produces magnetic and holds contact chip, makes spring leaf affect vibrating reed to swing, thereby sounds, and can also be clear that the size of amplitude simultaneously by the amplitude display screen.Cut off the electricity supply, magnetic disappears, and vibration stops, and sound disappears thereupon, and vibrating reed is no longer swing also.
The utility model science, novelty, practicality, easy to use, make simple, good demonstration effect.
Claims (1)
