The sound collector is soft and pliable so as to prevent injury to a person in the event the person is struck by the sound collector. The sound collector further comprises a damper formed from a soft sponge or foam material that prevents unpleasant pressure and/or injury to the ear drums in the event a loud sound is introduced into the sound collector due to someone yelling or blowing directly into the collector or the like.

  • Patent number: 4174588
    Abstract: A toy blood pressure monitoring device for simulating the blood pressure monitoring instrument used by doctors. The device comprises a housing having a diaphragm on one side and a pressure indicating scale on the other side. A fan is mounted for rotation within the housing and has a pointer coupled to the fan and coacting with the scale. A manually squeezable air impelling bulb is coupled to the housing and adapted when squeezed to substantially simultaneously direct a pulse of air against the fan and diaphragm. The air pulse imparts a rotative movement to the pointer over the pressure reading scale to simulate a blood pressure reading. The pulse of air further deflects the diaphragm which if held against a person's arm simulates the person's heart pulse beat.
