Document Type and Number:
Japanese Patent JP2010074704
Kind Code:
A
Abstract:

To provide an impact test apparatus for a microphone allowing a worker to confirm suitability/unsuitability of impact applied to the microphone.

The impact test apparatus for a microphone includes: an impact-absorbing material 20 formed of an elastic material impacted through the microphone 1; a piezoelectric element 30 arranged in the impact-absorbing material 20 and generating power by receiving impact pressure through the microphone 1; and a light emitting element 40 connected across output terminals of the piezoelectric element 30. Since the light emitting element 40 is turned on/off in response to the impact pressure through the microphone 1, suitability/unsuitability of the impact applied to the microphone 1 can be confirmed by a worker by viewing the indication of the light emitting element 40.
