Abstract
A sound reproduction device including a sound reproduction control circuit that performs a required computation on audio source data so as to generate sound reproduction data to send to a speaker; a first communication interface circuit that performs communication with a control device; a counter circuit whose count operation is controlled by a control signal received from the control device through the first communication interface circuit, and that outputs a state of the count operation; and an error control circuit that stops generation of the sound reproduction data by the sound reproduction control circuit based on the state of the count operation.
Claims9
A sound reproduction device comprising:
- a sound reproduction control circuit configured to perform a required computation on audio source data so as to generate sound reproduction data to send to a speaker;
- a first communication interface circuit configured to perform communication with a control device;
- a counter circuit whose count operation is controlled by a control signal received from the control device through the first communication interface circuit, and configured to output a state of the count operation;
- and
- an error control circuit configured to stop generation of the sound reproduction data by the sound reproduction control circuit based on the state of the count operation,
- wherein the control signal includes a start signal for starting the count operation, and a reset signal for resetting the count operation subsequent to the start signal, and
- in cases in which the state of the count operation is an overflow occurring as a result of the reset signal not having been received by the counter circuit, the error control circuit stops the generation of the sound reproduction data by the sound reproduction control circuit.
A sound reproduction device comprising:
- a first communication interface circuit configured to perform communication with a control device;
- a memory;
- and
- a processor connected to the memory, the processor configured to
- perform a required computation on audio source data so as to generate sound reproduction data to send to a speaker,
- control a count operation using a control signal received from the control device through the first communication interface circuit, and output a state of the count operation, and
- stop generation of the sound reproduction data based on the state of the count operation,
- wherein the control signal includes a start signal for starting the count operation, and a reset signal for resetting the count operation subsequent to the start signal, and
- in cases in which the state of the count operation is an overflow occurring as a result of the reset signal not having been received, the generation of the sound reproduction data is stopped.
