MULTI FUNCTIONAL MIC MODULE ASSEMBLY FOR PERSONAL NAVIGATION

摘要

The present invention relates to a high functional microphone module assembly for a personal navigation function, which is integrated with an altitude sensor sensing the precise position of a user while maintaining the function of a directional microphone. The device of the present invention includes a rectangular circuit substrate for embedding components; a first non-directional microphone embedded in one side of the circuit substrate; a second non-directional microphone embedded in the other side of the circuit substrate; a beam former embedded in a central part of the circuit substrate to receive a signal of the first and second microphones and make a beam of a predetermined shape have directivity; a sensor module embedded in the central part of the circuit substrate to output a predetermined sensing signal through an output terminal of the circuit substrate; and a case attached to the circuit substrate to form three embedding spaces for the first and second microphones, the sensor module, and the beam former. According to the present invention, the high functional microphone module assembly improves spatial efficiency by enabling the integration of sensors for high functions such as a personal navigation function with a compact structure by placing the altitude sensor (or other sensors) between the two microphones while providing directivity using the microphones.
