A Universal Serial Bus (USB) audio device kit includes a USB peripheral audio device and a passive USB-to-analog audio adapter. The USB peripheral audio device includes a USB interface configured to communicatively interface the USB audio peripheral device with a USB host device. The passive USB-to-analog audio adapter is configured to electrically interface the USB peripheral audio device with analog audio equipment via the USB interface.

Passive analog bypass for USB peripheral audio devices

An apparatus includes a wire connector configured to receive a connection to an external device. The external device includes a speaker and is configured to output audible sounds. The apparatus includes a connection detection circuit configured to determine whether the external device has connected to the apparatus through the wire connector. The apparatus includes an output test circuit configured to, upon detection of a connection to the external device, issue a test signal to the external device, evaluate a response to the test signal, the response based upon a resistance value within the external device, and determine an identity of the external device based upon the response to the test signal.

Headset model identification with a resistor

A system is provided for automated configuration of a connection interface between a headset device (e.g., a headset base) and a telephone (e.g., desktop phone). The system includes configuration circuitry designed to automatically perform a sequential analysis of multiple interface configuration options for the connection interface between the headset device and telephone. The analysis of each respective interface configuration option includes (a) accessing stored configuration information defining predefined switch positions for an array of controllable switches (e.g., optical switches) corresponding with the respective interface configuration option, (b) set the array of switches to the predefined switch positions specified by the accessed configuration information, and (c) performing a signal analysis to analyze electrical signals on the connection interface. The configuration circuitry may then select a best interface configuration option based on the signal analyses, and set the switches to the predefined switch positions corresponding with the selected best interface configuration option.

Systems and methods for automated configuration of telephone headset interface

A microphone assembly includes a microphone composed of a case having an open end and a printed circuit board. The printed circuit board is disposed in the open case end. The microphone assembly further includes a metal screen coupled to the case over the printed circuit board for shielding the microphone from electromagnetic interference. The metal screen includes several apertures.
