Abstract
An angle calculator calculates, based on acceleration detected by an acceleration sensor, a tilt angle of a transceiver with respect to the vertical direction. A selector (i) selects a first audio filter to operate if the tilt angle is less than a threshold angle, or (ii) selects a second audio filter to operate if the tilt angle is equal to or greater than the threshold angle. The second audio filter has a lower cutoff frequency that is higher than the lower cutoff frequency of the first audio filter.
Claims8
A wireless communications device comprising:
- an acceleration sensor configured to detect acceleration;
- an angle calculator configured to calculate, based on the acceleration, a tilt angle of the wireless communications device with respect to a vertical direction;
- a first audio filter and a second audio filter which have respective different frequency characteristics, the second audio filter having a lower cutoff frequency that is higher than a lower cutoff frequency of the first audio filter;
- and
- a selector configured to carry out selection of which one of the first and second audio filters to operate,
- the selector being configured to
- select the first audio filter if the tilt angle is less than a predetermined threshold angle, and
- select the second audio filter if the tilt angle is equal to or greater than the predetermined threshold angle.
