Abstract
A calibration method comprises adjusting an operating frequency of an air-pulse generating device, such that a sound pressure level (SPL) of the air-pulse generating device is within a specific range. The sound producing module comprises the air-pulse generating device configured to produce sound via generating a plurality of air pulses at a pulse rate corresponding to the operating frequency.
Claims20
A calibration method, configured to calibrate a sound producing module, the calibration method comprising:
- adjusting an operating frequency of an air-pulse generating device, such that a sound pressure level (SPL) of the air-pulse generating device is within a specific range;
- wherein the sound producing module comprises the air-pulse generating device configured to produce sound via generating a plurality of air pulses at a pulse rate corresponding to the operating frequency.
A sound producing module, comprising:
- a memory, configured to store a calibrated operating frequency;
- and
- an air-pulse generating device, configured to produce a sound via generating a plurality of air pules at a pulse rate corresponding to the calibrated operating frequency;
- wherein a second calibrated operating frequency is stored in a second memory within a second sound producing module distinct from the sound producing module;
- wherein the calibrated operating frequency is different from the second calibrated operating frequency;
- wherein a sound pressure level produced by the air-pulse generating device according to the calibrated operating frequency are consistent with a second sound pressure level produced by a second air-pulse generating device according to the second calibrated operating frequency which is different from the calibrated operating frequency;
- wherein the second sound producing module comprises the second air-pulse generating device.
