| 发明名称 | Apparatus and method pertaining to volume control | ||
| 摘要 | An apparatus comprises a volume-control user interface, a transmitter, an audio amplifier (having a corresponding amplification range), and a control circuit operably coupled to the foregoing components. This control circuit is configured to respond to a volume change made via the volume-control user interface that is within the amplification range of the audio amplifier by making a corresponding change to a volume level for an audio signal being transmitted by the transmitter. The control circuit is also configured to respond to a volume change made via the volume-control user interface that exceeds the amplification range of the audio amplifier by transmitting a volume-increase command. | ||

| 主权项 | 1. An apparatus comprising: a volume-control user interface; a transmitter; an audio amplifier having a corresponding amplification range; and a control circuit operably coupled to the volume-control user interface, the transmitter, and the audio amplifier and being configured to: receive a volume change made via the volume-control user interface;determine that the volume change is within the amplification range of the audio amplifier orexceeds the amplification range of the audio amplifierresponsive to the volume change being within the amplification range of the audio amplifier, making a corresponding change to a volume level for an audio signal being transmitted by the transmitter; andresponsive to the volume change exceeding the amplification range of the audio amplifier, transmitting a volume-increase command by the transmitter. | ||
