Abstract: PURPOSE:To increase a howling margin by arranging plural sound holes to a case part, sticking an acoustic resistive cloth to the sound hole part, forming pipe-formed sound leading tube to the case part and providing a microphone to one so as to hardly be affected by the operating condition. CONSTITUTION:In Figure, 4 is plural sound holes arranged constantly to a megaphone case part, 5 is the acoustic resistive cloth sticked to the sound holes 4, 6 is an urethane preventing standing wave, 7 is a front face sound hole of the microphone 1, 8 is pipe-formed sound leading pipe formed opposite to the sound holes. In the megaphone constituted in this way, the sound wave entering the sound holes 4, 7 interferes with each other for the phase, then the microphone 1 acts like a travelling wave type microphone and shows sharper directivity in higher frequencies. Further, in order to sharpen the directivity at low frequencies, a microphone having a sharp directivity is used as the microphone 1 so as to allow to show the primary gradient directivity at low frequencies.

Inventor: NOZAWA HIROSHI
IPC: H01L21/8247
Filed: 1978-07-07
Abstract: PURPOSE: To shorten the test time without easing the testing content by decreasing, by stages or gradually, the bit density for checking the writing-in function of P- ROM chips as the test progresses.
