Benefits of technology

The present invention is about a muffler for a vehicle that can tune the acceleration sound and make the vehicle sound sporty and dynamic. The muffler has a speaker chamber that produces sound when the exhaust gas flows into the muffler housing. The pressure of the exhaust gas is greater than a predetermined value, and a valve is opened / closed by the pressure of the exhaust gas to vibrate a thin plate and produce sporty and dynamic sound. The muffler can control noise generated by the exhaust gas and make the vehicle sound powerful without increasing the back pressure of the exhaust gas. The methods and apparatuses of the present invention have these features and advantages.

Problems solved by technology

However, the mufflers having the configuration described above in the related art can only reduce noise or increase the engine power by changing the back pressure while expanding or contracting the exhaust gas channel, but they cannot implement sporty and dynamic sound by tuning at a desired frequency band.
