Description
Technical field
The present invention relates to experiment damping sheets when damping sheet technical field more particularly to a kind of vibrometer.
Background technology
Timer refers to using specific principle come the device of time of measuring, and common timer is a kind of on the market now
For electromagnetism timer, which is also known as mechanical timer, and mechanism group becomes, and external power supply plug, electromagnetic coil is used for
The components such as the wiring board of conversion circuit, and the movement character wheel screen of display time composition.Its operation principle is by outside
Power supply generates a high frequency voltage, and together with to above electromagnetic coil, electromagnetic coil generates one and hands over frequency magnetic field high frequency voltage, to
Reciprocating motion is generated, the running for the gear mechanism for driving movement is moved back and forth, passes through the cogged drive manner of band of number
The time is indicated, in order to improve the precision of detection, generally requires damping sheet to reduce its vibration, but for being tested when vibrometer
Damping sheet, the damping material majority of sound insulation noise abatement is relatively simple for structure, and effect is poor.
