Abstract
A hands-free voice communication apparatus with integrated speakerphone and earpiece is described. The speakerphone includes a loudspeaker and zero, one or multiple microphones. The earpiece includes a small loudspeaker, one or more microphones, a wireless module, and a digital signal processing (DSP) module. The hands-free device support hands-free voice communication via the speakerphone or the earpiece. The earpiece is functional when removed from the speakerphone case and may be used for voice communication with privacy. When the earpiece is placed back in the speakerphone case, the speakerphone is functional and may be used for voice communication with convenience. The DSP module performs digital signal processing for both the earpiece and the speakerphone, e.g., using different sets of parameters. The speakerphone may be a standalone device or may be part of a communication device. The wireless module communicates with the communication device, which provide end-to-end communication with a far-end user.
