发明名称 Microphones with equal sensitivity
摘要 <p>The invention concerns a method for the production of microphones (1) with a sensitivity stipulated within narrow limits, in which the microphones each have a microphone capsule (2) and an amplifier (3). <??>The method according to the invention is characterized by the fact that a network (6) of passive components, preferably resistors (Ri), is allocated to amplifier (3), and by the fact that the sensitivity of the microphone (1) is measured and the passive components are then disconnected, through whose disconnection the amplification of amplifier (3) is changed in the desired manner. <??>The invention also concerns a microphone (1) with a sensitivity stipulated within narrow limits, in which the microphone has a microphone capsule (2) and an amplifier (3). <??>Such a microphone is characterized by the fact that the amplifier (3) has a network (6) of passive components, preferably resistors (Ri), and that at least one of the passive components is disconnected, for example, destroyed. <IMAGE></p>
