Earphone socket

Abstract

The invention discloses an earphone socket. The earphone socket comprises a circuit board and a conducting strip set arranged in the length direction of the circuit board. The conducting strip set comprises a first conducting strip and a second conducting strip which are adjacent and are insulated from each other. The tail end of the first conducting strip and the tail end of the second conducting strip are provided with a first elastic piece and a second elastic piece respectively, wherein the first elastic piece is opposite to the second elastic piece, and the second elastic piece is farther away from the circuit board compared with the first elastic piece. When an earphone plug is plugged in the earphone socket, a metal head at the tail end makes elastic contact with the first elastic piece and the second elastic piece at the same time. According to the earphone socket, a plugging signal of the earphone plug can be transferred to a control circuit, so the situation that a non-metal object is plugged by mistake, so an error judgment is made is prevented; meanwhile, due to the arrangement mode of the first elastic piece and the second elastic piece, welding feet of the first elastic piece and the second elastic piece can be made nearer, and the circuit board can be made narrower; therefore, the earphone socket can be made thinner.

Description

Technical field [0001] The invention relates to an earphone connection structure, in particular to an earphone socket. Background technique [0002] For ease of use, many devices are designed with a headphone jack and external speakers at the same time, such as computers, MP4, tablet computers, digital TVs, etc., and similar devices have both external amplifier and earphone playback functions. [0003] In actual use, users often require that after the headphone plug is inserted, the external speakers of the device stop working, and earplugs are selected as the only sound source output terminal, which makes the headphone jacks used on similar devices need to have Circuit selection function. When the earphone plug is inserted, the corresponding structure and circuit design are required in the jack to identify the plug insertion action and disconnect the speaker circuit. [0004] Such as figure 1 As shown, the traditional headphone socket of this kind uses a structure in which the fix...

Problems solved by technology

However, when this earphone socket is inserted into other non-metallic columnar objects such as rubber plugs, it will also be judged that the earphone plug 3 is inserted, thus causing a misjudgment

At the same time, since this kind of earphone socket has multiple pairs of welding feet K arranged on opposite sides of the earphone jack, its circuit board needs to be made very wide, which limits the thickness and installation position of the entire earphone socket, and the installation flexibility is poor.
