Abstract
Apparatus (100) for controlling the volume of a speaker (109) by restricting the volume level of the speaker (109) at power on. The apparatus (100) includes a microprocessor controller (103) for operating the speaker (109) at a first volume level prior to powering off. Upon power on, the microprocessor controller (103) determines a statistic based on a time of the received power-on command, and restricts the volume level of the speaker (109) based on the statistic.
Claims18
A method of controlling a volume of a speaker, the method comprising the steps of:
- operating the speaker at a first volume level;
- receiving a power-off command;
- receiving a power-on command;
- determining a time interval, the time interval being related to a difference in time between a last time the speaker was operated and a time of the received power-on command;
- comparing the time interval to a threshold;
- and
- operating the speaker at a second volume level based on the comparison.
A method of controlling a volume of a speaker, said speaker capable of operating at a highest level and a lowest level, the method comprising the steps of:
- operating the speaker at a first volume, said first volume at a level between the highest and the lowest level;
- receiving a volume-up command;
- determining a statistic based on a time of the received volume-up command;
- and
- operating the speaker at no higher than the first volume based on the statistic.
An apparatus for controlling a volume, the apparatus comprising:
- a speaker;
- an amplifier coupled to the speaker;
- a clock coupled to the amplifier;
- a memory coupled to the clock;
- a command unit coupled to the clock;
- and
- a microprocessor controller responsive to the command unit, said microprocessor controller operating the speaker at a first volume level, receiving a power-off command from the command unit, receiving a power-on command from the command unit, determining a time interval, the time interval being related to a difference in time between a last time the speaker was operated and a time of the received power-on command, comparing the time interval to a threshold, and operating the speaker at a second volume level based on the statistic.

- an amplifier coupled to the speaker;
- a clock coupled to the amplifier;
- a memory coupled to the clock;
- a command unit coupled to the clock;
- and
- a microprocessor controller responsive to the command unit, said microprocessor controller operating the speaker at a first volume, said first volume at a level between the highest and the lowest level, said microprocessor controller receiving a volume-up command from the command unit, determining a statistic based on a time of the received volume-up command, and continuing to operate the speaker at no higher than the first volume based on the statistic.
