Abstract
Thus there is provided a microphone (10) having a first end (12) with a first slip ring (100) which is divided into at least first and second segments (GND, 300). The first slip ring (100) co-operates with a microphone head (12) when the microphone head (12) is fastened to the first end (12) of the microphone by means of a screw connection. The microphone further has a detection unit (16) coupled to the at least first and second segments (GND, 300) of the first slip ring (100) to detect rotation of the microphone head (12).
Claims4
A microphone for generating an audio output signal comprising:
- a replaceable microphone head,
- a first end with a first slip ring which is divided into at least first and second segments wherein the first slip ring co-operates with the microphone head when the microphone head is fastened to the first end of the microphone by means of a screw connection, and
- a detection unit coupled to the at least first and second segments of the first slip ring to detect rotation of the microphone head when the microphone head is replaced,
- wherein the detection unit is configured to mute the audio output signal of the microphone when a rotation of the microphone head is detected.
A microphone comprising:
- a replaceable microphone head and a microphone housing,
- a first resistor in the microphone head, and
- a second resistor in the microphone housing,
- wherein the first resistor is electrically connected to the second resistor when the microphone head is fastened to the microphone housing, wherein a measurement voltage is applied to the second resistor and wherein a voltage between the first and second resistors is measured in order to determine the first resistor with the microphone head and thus to identify the microphone head.
A microphone comprising:
- a replaceable microphone head, and
- a microphone housing, and
- a first resistor in the microphone head,
- the microphone head comprising at least one slip ring for co-operating with contacts at a first end of the microphone housing,
- wherein the first resistor is connector to the at least one slip ring, and
- wherein the first resistor is selected specifically for a type of a microphone head permitting identification of the type of microphone head by determining the resistor provided in the microphone head.
A microphone for generating an audio output signal comprising:
- a microphone housing having a first end, and
- a replaceable microphone head, comprising at least a first slip ring,
- wherein the first slip ring is divided into at least first and second segments, and
- wherein the first slip ring co-operates with first contacts at the first end of the microphone housing when the microphone head is fastened to the first end of the microphone housing by means of a screw connection, and
- a detection unit connected to the first contacts for detecting rotation of the microphone head when the microphone head is replaced,
- wherein the detection unit is configured to mute the audio output signal of the microphone when a rotation of the microphone head is detected.
