Description

Headphone and microphone socket female

technical field

The utility model relates to the technical field of audio output connecting devices, in particular to a female socket used for earphones and microphones.

Background technique

INTEL launched the high-definition audio standard Intel HD Audio, which has regulations on how to reduce noise in various aspects. For example, when using the audio jack on the front panel of the computer, plugging in the male headphone or loudspeaker will cause noise on the back panel of the computer. The audio output from the audio jack on the motherboard produces some noise interference, which is not allowed in the new standard. Therefore, the mark

The standard stipulates that when using the audio jack on the front panel, the audio output on the rear panel of the computer should be shielded through the jumper on the headphone jack. The two jumper heads are electrically connected, and the signal receiving pin on the control chip that is electrically connected to the headphone socket senses the headphone socket currently in use, and sends a signal to the corresponding headphone socket.

The port of the headphone socket outputs the audio signal, which shields the headphone socket on the back panel of the computer; when using the headphone socket on the back panel of the computer, it shields the headphone socket on the front panel of the computer, and the audio signal is only transmitted to the headphone socket on the back panel of the computer. The same goes for the headphone jack output, as well as the audio input jacks on the computer's front and rear panels. In response to Intel's new standard, various computer accessories manufacturers have designed corresponding headphone jacks. At present, a metal shrapnel is fixed in the shell of the headphone bracket, and an insulating plastic sheet is fixed at the end of the metal shrapnel. The plastic sheet is in two jumps. Between the wire head and the earphone insertion hole, when the male head of the earphone or amplifier is inserted, the male head presses the plastic sheet to one side of the jumper wire, so that the two jumper wires contact and are electrically connected. Although this design can meet the requirements of the new standard, the insulating plastic fixed on the end of the metal shrapnel is easy to fall off during use, and the production is troublesome and the production cost is high.

On the adjacent side of the shrapnel, one leg is arranged on the opposite side of the two legs, and one leg abuts against the shell.

Wherein, an audio shielding switch is provided in the plastic seat, and the insulating shrapnel of the audio shielding switch is integrally formed with the plastic seat.

Wherein, the audio shielding toggle switch includes an insulating shrapnel, four legs and five legs for transmitting jumper signals, and the four legs and five legs are respectively installed on the slots on the side of the plastic seat provided with the insulating shrapnel.

Wherein, the four legs are provided with elastic contacts corresponding to the five legs in contact with each other.

Wherein, the insulating shrapnel is bonded to the four legs.

Wherein, the supporting legs include three supporting legs and two supporting legs for transmitting left and right channel audio signals, and the three supporting legs and the second supporting legs are installed on the slots on the other two sides of the plastic seat.

Wherein, the shell is a metal shell, the shell is socketed with the plastic seat, and the shell is conductively connected to a foot used for audio grounding signal transmission, and the foot is installed on the plastic seat with an insulating On the card slot on the adjacent side of the shrapnel.

Beneficial effects of the utility model: the female socket of the earphone and the microphone includes a plastic seat for mounting the feet and a casing for socketing the plastic seat, the front end of the plastic seat has a round hole, and the inside of the plastic seat is provided with a clip for installing five legs. groove, the inside of the plastic seat is connected with insulating shrapnel, and the insulating shrapnel and the plastic seat are integrally formed; four legs and five legs are set on one side of the insulating shrapnel in turn, three legs are set on the opposite side of the insulating shrapnel, and two legs are set on the opposite side of the insulating shrapnel. On the adjacent side, one leg is set on the opposite side of the second leg, and one leg is in contact with the shell; inserting the male head can make the four legs and five legs become closed, but the four and five legs are insulated from the male head; the socket The female base has simple structure, easy manufacture, low cost and high durability.
