Further, the resistances of the first resistor R1 and the second resistor R2 are 33R, the resistances of the third resistor R3 and the seventh resistor R7 are 0R, and the resistances of the fourth resistor R4 and the fifth resistor R5 are 24R.

The utility model discloses a theory of operation: the circuit is connected with electronic equipment through a connecting end PhoneJack4, and is connected with a microphone MK through an M + pin and an M-pin, a user can control whether the microphone MK works or not through controlling a microphone switch S1, and the microphone switch S1 has the functions of a, lightly pressing a key to answer a call; b. the general call is finished by lightly pressing a key to hang up the call, but some mobile phone programs are set differently, so that silence occurs, or the call is kept, and at the moment, the call can be hung up only by pressing a key of a microphone switch S1 for a long time; C. the playing/pausing function in the mobile phone music player can be controlled, the next song is clicked in double, and the previous song is clicked in three times; fast forward is realized in the apple mobile phone, hands are not released after double-click twice, fast backward is realized in the apple mobile phone, hands are not released after continuous pressing for 3 times, and partial mobile phones enter a voice function by long-pressing a microphone switch S1 key. When the first Speaker switch SW-L and the second Speaker switch SW-R are closed, the signal of the connecting end PhoneJack4 is transmitted to the left Speaker L-Speaker and the right Speaker R-Speaker through the L pin and R via the first resistor R1, the second resistor R2, the first capacitor C1 and the second capacitor C2 to generate the EQ1 effect, and when the first Speaker switch SW-L is connected with the second Speaker switch SW-R, the signal of the connecting end PhoneJack4 is transmitted to the left Speaker L-Speaker and the right Speaker R-Speaker through the L pin and R via the fourth resistor R4 and the fifth resistor R5 to generate the EQ2 effect, so that a user can enjoy more comfortable music by adjusting the EQ.

After the technical scheme is adopted, the utility model discloses beneficial effect does: adding a tone for consumption, wherein in the EQ1 mode, the sound is warmer, and the heavy bass is stronger; in the EQ2 mode, brighter middle and high tones can be provided, so that users can adjust EQ more conveniently and more quickly in different environments to enjoy more comfortable music.
