Abstract

A transmission device being able to launch alarm according to sound type is prepared as picking up ambient sound character and comparing it with various types of sound characters in databank then judging whether ambient sound belongs to sound type in databank or not by sound identifier, outputting alarm sound by emergency indicator if ambient sound belongs to sound type in databank and using sound mixer to output said alarm sound or to synthesize said alarm sound with sound played by sound playing unit then to output it.

Description

technical field [0001] The invention relates to a sound transmission device and method, in particular to a transmission device and method that can issue an alarm according to the type of sound. Background technique [0002] Portable audio playback devices, such as CD players and mp3 players, have been widely used by the public in today's society. And the user generally listens to the music of the Walkman with an earphone or a headset. [0003] Users wearing earphones often listen to the music played by the earphones while walking on the street, but these users often only focus on listening to the music and ignore the external warning sounds (such as: car horns), or The external warning sound cannot be heard because the volume of the sound from the earphone is too loud. But if the user fails to respond to the external warning sound in time, dangerous accidents may occur. [0004] refer to Figure 4 , in order to solve the above-mentioned problem, U.S. Patent No.US6782106B1...
