摘要： A mobile information terminal including a directional microphone provided with a front port, a diaphragm and an electrode, wherein the microphone includes a front air chamber formed between a flexible thin film which covers an opening of the front port and the diaphragm, and a rear air chamber formed between a case and the electrode by hermetically covering the electrode with the case.
The mobile information terminal is equipped with two pulse wave detection sensors and a signal processing unit which computes the blood pressure based on the time difference of the pulse wave signals.
