BRIEF SUMMARY OF THE INVENTION The wireless multimedia device of the present invention substantially meets these above-identified needs and others. One embodiment provides a wireless earpiece/microphone operable to support enhanced call functions. More specifically, this wireless headset supports voice communications over multiple servicing networks. The wireless headset includes a wireless earpiece, a wireless microphone, and a user interface wherein either the earpiece or microphone are a detachable module. The wireless earpiece may receive radio frequency (RF) signals and render voice communications contained within the received RF signals audible. This wireless earpiece further includes a wireless interface to receive and transmit the RF signals between the earpiece and a host device. Processing circuitry operably coupled to the wireless interface recovers digital audio signals from the received RF signals. A digital-to-analog converter (DAC) couples to the wireless interface and processing circuitry. The DAC produces analog audio signals from the digital audio signals and provides this analog audio signal a speaker module which receives the analog audio signal and renders the stat communications contained therein audible. The wireless microphone captures audio signals and converts the audio signals into RF signals. This modular wireless microphone further includes a microphone transducer to capture the audio signals and convert the captured audio signals into analog audio signals. An analog-to-digital converter (ADC) receives the analog audio signals and produces a digital audio signal. Processing circuitry processes the digital audio signals to produce RF signals which are transmitted by a wireless interface contained within the modular wireless microphone. A user interface couples to the wireless earpiece and/or wireless microphone and is operable to initiate enhanced call functions based upon user input.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS FIG. 1 is a diagram of a wireless headset in accordance with the present invention;
DETAILED DESCRIPTION OF THE INVENTION FIG. 1 is a diagram of a modular wireless headset 10 wirelessly coupled to host device 16 that includes earpiece 12 and microphone 14. Earpiece 12 may be a separate physical device from microphone 14. Earpiece 12 may be detached from the headset. Headset 10 may include a frame 9 that conforms to the shape of the user's head. This frame may be formed from shaped batteries and may physically dock to the earpiece and microphone. Accordingly, earpiece 12 and microphone 14 may be separate communication devices that individually communicate with host device 16 via separate communication pathways. As shown, earpiece 12 may communicate with host device 16, which may be a cellular telephone, wire line telephone, laptop computer, personal computer, personal digital assistant, etc., using transceiver (or receiver) 13 of FIG. 2 via a first communication pathway 18. Although shown as being external to earpiece 12, transceivers 13 and 15 may be integrated within earpiece 12 and microphone 14. Host device 16 is operable to establish a wireless pathway to earpiece 12 or microphone 14. The microphone 14 may communicate with the host device 16 using transceiver (or transmitter) 15 of FIG. 2 via a second communication pathway 20. Microphone 14 may also be detachable mounted on a frame similar to form and function to frame 9. Either or both earpiece 12 and microphone 14 may have a user interface 22. If the communication pathways are established in accordance with the Bluetooth specification, communication resources 18 and 20 may be different timeslot allocations on the same synchronous connection orientated (SCO) link, or may be separate SCO links.
