Patent abstract
A motorcycle audio system is provided with circuitry to toggle the helmet mounted microphone of both the driver and the passenger on and off by use of the PTT (push to talk) switches commonly provided for use with a CB radio. Activation of a PTT immediately causes both microphones “on” regardless of their prior state. If the PTT is released during a predetermined short period, the microphones are turned off only if they were on prior to activation of the PTT and remain on only if they were off prior to activation. If the PTT is released after the predetermined period, the microphones remain on only if they were on prior to activation.
