Ear microphone with enhanced sensitivity

一种耳塞式传声器装置(10)，其构形适于被支撑在耳朵中。该传声器装置(10)包括一个传声器元件(17)，此元件容纳在一个壳体(25)中，此壳体一端的构形适于放置在使用者的耳道中。当如此放置壳体(25)时，传声器元件(17)紧靠使用者的头设置，壳体(25)和使用者的头配合改变传声器的灵敏度，以提供使传声器元件(17)朝向使用者的嘴的增强的方向取向，并且与壳体和传声器元件不是放置在耳道处时相比，提供更高的灵敏度，从而增强使用者的语音的拾取。一个扬声器元件(13)可以容纳在该耳塞式装置(10)内，并可以通过壳体和传声器之间的一个垫圈(50)桥被机械隔离，从而避免反馈。这个系统可以工作在全双工方式下，并且使得使用者能够通过计算机的调制解调器、电话网络和其它通信系统进行不用手的通信和直接的语音指令操作。 An ear-mounted microphone device configured for being supported in the ear. The microphone device includes a microphone element contained within a housing which is configured at one end to be mounted at a user's ear canal. When the housing is so mounted, the microphone element is positioned closely adjacent to the user's head such that the housing and the user's head cooperatively alter the sensitivity of the microphone so as to provide an enhanced directional orientation and sensitivity of the microphone element toward the user's mouth to a greater degree than is provided when the housing and microphone element are not mounted at the ear canal, so as to enhance pickup of the user's voice. A speaker element may be included within the ear device and can be decoupled mechanically by a gasket bridge between the housing and microphone so as to avoid feedback. This system can operate with full duplex and enable hands free communication and direct voice command by user through computer modems, telephone networks and other communication systems.
