Abstract

Currently, audio mode is triggered using an audio sense input signal from the audioshoe. Once the signal is pulled to a low-level voltage, the instrument goes into audio mode. This requires a fourth physical contact on the audioshoe and instrument side. This requires a fourth electrical contact at both the audioshoe and the instrument side to trigger the instrument into audio mode. A novel solution allows the audioshoe function to be activated by using a magnetic reed switch. Thus, the principle of this solution is using a magnet at the audioshoe side to trigger the magnetic reed switch at the instrument side for audioshoe function (see Figures 1-4). This reed switch is connected to the audio sense input at the instrument side. Once the audioshoe is attached to the instrument, the magnet in the audioshoe is close enough to switch on the reed switch at the instrument side. This pulls the audio sense signal at the instrument side to a low voltage level and this switches it to audio mode.

Currently, audio mode is triggered using an audio sense input signal from the audioshoe. Once the signal is pulled to a low-level voltage, the instrument goes into audio mode. This requires a fourth physical contact on the audioshoe and instrument side. This requires a fourth electrical contact at both the audioshoe and the instrument side to trigger the instrument into audio mode.

A novel solution allows the audioshoe function to be activated by using a magnetic reed switch. Thus, the principle of this solution is using a magnet at the audioshoe side to trigger the magnetic reed switch at the instrument side for audioshoe function (see Figures 1-4). This reed switch is connected
to the audio sense input at the instrument side. Once the audioshoe is attached to the instrument, the magnet in the audioshoe is close enough to switch on the reed switch at the instrument side. This pulls the audio sense signal at the instrument side to a low voltage level and this switches it to audio mode.

The instrument might also have another reed switch for telecoil activation. Then the reed switches are positioned and oriented so that the magnet at the audioshoe does not trigger the reed switch for telecoil and vice versa. It can be placed 90 degrees perpendicular such that it will be activated with the magnet in different angle. This can prevent any magnet from triggering both sw...
