Description

Headphone and microphone socket female

technical field

The utility model relates to a socket female seat applied to 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 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 socket. The two jumper heads on the socket are electrically connected, and the signal receiving pin on the control chip electrically connected to the headphone socket senses the headphone socket currently in use, and outputs an audio signal to the port of the corresponding headphone socket, that is, The headphone jack on the back panel of the computer is shielded; when the headphone jack on the back panel of the computer is used, the headphone jack on the front panel of the computer is shielded, and the audio signal is only output to the headphone jack on the back panel of the computer. Figure 1 is its circuit Schematic diagram, wherein, 15,12 are jumpers on the headphone jack on the front and rear panels of the computer respectively, and 13,14 are the earphone jacks on the front and back panels of the computer respectively; In response to Intel's new standard, various computer accessories manufacturers have designed corresponding headphone sockets. At present, there is mainly a metal shrapnel fixed in the shell of the headphone socket, and an insulating plastic sheet is fixed at the end of the metal shrapnel. The plastic sheet is between the two jumpers. Between the headphone and the earphone insertion hole, when the male headphone or amplifier is inserted, the male head presses the plastic sheet to one side of the jumper wire, so that the two jumper wires are in contact and 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 also high.

Utility model content

The purpose of the utility model is to provide an earphone socket with simple structure, easy manufacture, low cost and high durability to solve the shortcomings of the prior art.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The female socket of the earphone and microphone is made of a plastic seat for installing the socket feet. There is a round hole in the front of the plastic seat, and there are slots for installing five terminals inside the plastic seat. The second and fifth legs are distributed on both sides. Left and right channel audio signal transmission; one leg is located on the other side of the plastic seat, responsible for audio grounding signal transmission, and one leg is connected to the metal shell to form a better anti-interference electromagnetic shielding; the third and fourth legs are distributed on the plastic seat On the other side, it is on the same side as the plastic shrapnel. When the male plug is inserted, the three or four legs can be changed from disconnected to contacted. This design is used for the jumper switch of the Inter HD Audio circuit.

The utility model has the advantages of simple structure, easy manufacture, low cost, not easy to damage and long service life.

Detailed ways

As shown in Figures 1 to 6, the female socket for earphones and microphones is composed of a plastic seat 12, five terminals, a metal shell 13 and a plastic cover 14. Seat slot 1, two legs 8 into slot 2, three legs 9 into slot 3, four legs 10 into slot 4, one leg 7 into rubber seat slot 5, plastic back cover 14 into buckle 6, and then metal The shell 13 is fastened with the plastic seat 12, and the plastic spring 15 is located on the side of the third and fourth legs. Inserting the male head 16 can make the disconnected state become a closed state, but the third and fourth legs are insulated from the male head 16.

The above are only preferred embodiments of the utility model, so all equivalent changes or decorations made according to the structure, features and principles described in the utility model patent scope are included in the utility model patent scope .
