Radio communication device
First Claim
1. A radio communication device comprising:
- a voice level comparator configured to compare a level of a voice signal collected by a microphone with a VOX level;
a transmission determination unit configured to instruct a transmitter to transmit the voice signal, when the level of the voice signal is equal to or greater than the VOX level, based on a comparison result by the voice level comparator;
a switch;
a timer configured to start to measure an elapsed time from a point of time when the switch is operated; and
a VOX level selector configured to set a first VOX level as the VOX level when the elapsed time measured by the timer exceeds a reference elapsed time, and to set a second VOX level which is smaller than the first VOX level as the VOX level when the elapsed time measured by the timer stays within the reference elapsed time.

Abstract
A voice level comparator compares a level of a voice signal collected by a microphone with a VOX level. A transmission determination unit instructs a transmitter to transmit the voice signal, when the level of the voice signal is equal to or greater than the VOX level, based on a comparison result by the voice level comparator. A timer starts to measure an elapsed time from a point of time when a switch is operated. A VOX level selector seta a first VOX level as the VOX level when the elapsed time measured by the timer exceeds a reference elapsed time, and sets a second VOX level which is smaller than the first VOX level as the VOX level when the elapsed time measured by the timer stays within the reference elapsed time.

-
a voice level comparator configured to compare a level of a voice signal collected by a microphone with a VOX level; a transmission determination unit configured to instruct a transmitter to transmit the voice signal, when the level of the voice signal is equal to or greater than the VOX level, based on a comparison result by the voice level comparator; a squelch processor configured to instruct a mute controller to mute a received signal generated by a receiver, when a noise level of the received signal is equal to or greater than a threshold value; a timer configured to start to measure an elapsed time from a point of time when the squelch processor instructs to mute the received signal; and a VOX level selector configured to set a first VOX level as the VOX level when the elapsed time measured by the timer exceeds a reference elapsed time, and to set a second VOX level which is smaller than the first VOX level as the VOX level when the elapsed time measured by the timer stays within the reference elapsed time. - View Dependent Claims (3, 4, 5, 6)
