jerry兄, 發聲組件可以點整, 我都相做engine聲
you need install a IC chips and a amplifier , a speaker.
You can self make or buy from other country. if buy need around HK1500, and self make around HK500, very interesting ga, now i testing my self make + some other country components can run with "man diseal engine" sound when move forward or backward and sure have "Horn" sound .. try it ! Fantastic componets for RC boat, but need 12V or above to run a amplifier. |
