Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to a 5-pole waterproof headphone jack connector with PTT function. Background Technology
[0002] Push-to-Talk (PTT) is a mobile technology that enables quick one-to-one or one-to-many calls, similar to a walkie-talkie. Regular mobile phones do not support this function, but some phones compatible with Qualcomm BREW can gain PTT support through a software upgrade. After activating the PTT function, users only need to press the corresponding button on their phone to talk to the selected group. However, existing headphone jack connectors generally use a 4-pole design (including left channel, right channel, ground, and microphone). Due to the lack of a dedicated control pole, the PTT function cannot be directly activated; additional button operation on the phone is required, affecting the headphone's user experience. Furthermore, existing headphone jack connectors have poor sealing and waterproofing performance, making devices prone to short circuits due to water ingress into the headphone jack.
