Abstract
A domestic gas appliance is disclosed. In one implementation the appliance includes a burner and a gas control valve situated to deliver and vary a flow of a gas to the burner. The gas control valve has an actuator that induces an opening and/or closing of the flow control valve dependent on a control signal delivered to the actuator. A control device is electrically coupled to the actuator and is used to control the opening and closing of the gas control valve. The control device is coupled to an audio input and is configured to receive an analog sound signal and to generate the control signal based on the analog sound signal. A method of modulating a flame in a burner of a domestic gas appliance is also disclosed. In one implementation the method includes producing an analog sound signal and subsequently creating a reference signal based on the analog sound signal. A control signal is produced using the reference signal with the relationship between the reference signal and the control signal being linear, logarithmic or potential. The control signal is delivered to an actuator of a gas control valve that is situated to control the flow of gas to the burner, the control signal acting upon the actuator to cause the actuator to open and/or close to modulate the flame in the burner.
