SOUND RECOGNIZER HAVING AUTOMATIC SOUND STORAGE FUNCTION

摘要

PURPOSE: A sound recognizer having an automatic sound storage function is provided to store a sound of a driver when a start key is in a preheating status and store and generate an input sound when an accident generation signal is sensed. CONSTITUTION: A sound input section(10) converts a sound from a microphone(11) into a digital signal. A sound output section(20) converts a digital sound from the sound input section(10) into an analog signal and outputs it through a speaker(21). A sound processor(30) stores the digital sound from the sound input section(10) in a memory(32) and outputs the digital sound stored in the memory(32) through the speaker(21) according to a sound output request. A vehicle status input section(40) applies an accident generation signal to the sound processor(30) when an accident generation sensing signal from a vehicle air bag ECU(41) is inputted thereto.
