    摘要: A case for an electronic device includes a shell and at least three electrical connectors. The shell receives the electronic device and covers at least a portion of the electronic device. A first electrical connector is on an interior of the shell and electrically connects the case to an electrical interface of the electronic device when the electronic device is installed in the case. A second electrical connector is on an exterior of the shell and electrically connects a first external electrical device to the electronic device through the electrical interface of the electronic device. A third electrical connector is on the exterior of the shell and electrically connects a second external electrical device to the electronic device.

    摘要: A handset device and an interface unit used to transmit at least one of a command signal and an audio signal to a hearing device by way of a wireless connection are disclosed. The handset device has an audio output and is configured to transmit a power signal configured to power the interface unit to the interface unit by way of a wired connection connecting the audio output of the handset device with an audio input of the interface unit. The handset device is also configured to transmit the command signal and/or the audio signal to the interface unit by way of the wired connection. In certain embodiments, the audio signal and at least one of the command signal and the power signal have pre-assigned and non-overlapping frequency ranges.
