Headset Jack and Method for Detecting Whether Headset Is Inserted In Position

摘要

A headset jack includes a side wall, a bottom part, a clamping component on the side wall, a first detection end at the bottom part, a second detection end on the side wall or at the bottom part, and a membrane switch electrically connected to the second detection end. The clamping component is configured to clamp a headset plug when the headset plug is inserted into the headset jack. When the headset plug is not inserted in position, the membrane switch is electrically isolated from the first detection end. The membrane switch is configured to generate elastic deformation under a pressure of the headset plug when the headset plug is inserted in position and be electrically connected to the first detection end.

1. A headset jack, comprising:
a side wall; a bottom part; a clamping component on the side wall; a first detection end at the bottom part; a second detection end on the side wall or at the bottom part; and a membrane switch electrically connected to the second detection end, wherein the clamping component is configured to clamp a headset plug when the headset plug is inserted into the headset jack, wherein when the headset plug is not inserted in position, the membrane switch is electrically isolated from the first detection end, and an electrical characteristic between the first detection end and the second detection end is a first electrical characteristic, wherein the membrane switch is configured to generate elastic deformation under a pressure of the headset plug when the headset plug is inserted in position and be electrically connected to the first detection end, so as to electrically connect the first detection end to the second detection end, and change the electrical characteristic between the first detection end and the second detection end to a second electrical characteristic, and wherein the second electrical characteristic is used to generate an electrical signal to reflect that the headset plug is inserted into the headset jack in position.
