First Claim
Patent Images
1. A mobile communication device comprising:
- a loudspeaker for reproduction of speech from a speech signal;
a vibrator;
a detector for measuring background noise in relation to said reproduced speech; and
a vibrator processing unit for controlling operation of said vibrator during the speech reproduction based on a level of said background noise.

Abstract
A mobile communication device includes a loudspeaker for reproducing speech from a speech signal, a vibrator, and a measuring unit for measuring background noise in relation to the reproduced speech. The communication device further includes a vibrator processing unit for generating a control signal dependent on the background noise for controlling operation of the vibrator during speech reproduction dependent on a level of the background noise.

11. A method of enhancing intelligibility of speech reproduced by a mobile communication device from a speech signal, said mobile communication device comprising a vibrator, the method comprising the acts of:
-
determining background noise in relation to said reproduced speech; generating a control signal dependent on said background noise; and applying said control signal to said vibrator so as to selectively operate said vibrator during speech reproduction based on a level of said determined background noise so that the control signal has different values for driving the vibrator at different vibration levels for different noise levels of said determined background noise. - View Dependent Claims (13, 14)
