Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to FIG. 1(A), which shows a structural diagram of an ordinary earphone plug 100. The ordinary earphone plug 100 can also be called an audio source plug. .

Please refer to Fig. 1 (A) and Fig. 1 (B), the electronic equipment in the preferred embodiment of the present invention has loudspeaker (comprising right loudspeaker 201 and left loudspeaker 202) and the wireless interface that is used to receive wireless audio signal, this implementation In an example, the wireless interface is a Bluetooth interface for receiving Bluetooth audio signals. The Bluetooth interface includes 4 signal input terminals, which are: the right channel terminal SPKR_P for receiving the right channel audio signal, the right common terminal SPKR_N for grounding, and the left channel terminal SPKL_P for receiving the left channel audio signal , The left common terminal SPKL_N for grounding. In fact, the right common terminal SPKR_N and the left common terminal SPKL_N are ground ports.

The electronic device also includes an earphone socket 300, which is connected to the speaker and the wireless interface. The earphone socket includes a first elastic piece pin1, a second elastic piece pin2, a third elastic piece pin3 and a fourth elastic piece pin4. The fifth shrapnel pin5 of the right channel end SPKR_P of the wireless interface is connected to the sixth shrapnel pin6 of the left sound channel end SPKL_P of the wireless interface, and the first shrapnel pin1 is connected to the right public end SPKR_N and the right speaker of the wireless interface The ground terminal GND1 of 201, the second spring piece pin2 is connected to the left public terminal SPKL_N of the wireless interface and the ground terminal GND2 of the left speaker 202, the third spring piece pin3 is connected to the right channel end R of the right speaker 201, And it is detachably connected with the fifth elastic piece pin5, and the fourth elastic piece pin4 is connected with the left sound channel end of the left speaker 202, and is detachably connected with the sixth elastic piece pin6.

Please compare and refer to Figure 2(A) and Figure 2(B). When the external sound source plug 100 is not inserted into the earphone socket 300, the third shrapnel pin3 and the fifth shrapnel pin5 are turned on, and the right channel terminal SPKR_P of the wireless interface transmits the received right audio signal to the third shrapnel through the fifth shrapnel pin5 pin3, and then output to the right speaker 201; the fourth shrapnel pin4 and the sixth shrapnel pin6 conduction, the left audio channel terminal SPKL_P of the wireless interface transmits the received left audio signal to the third shrapnel pin4 through the sixth shrapnel pin6, and then outputs to the left speaker 202 to realize wireless audio input to the speaker.

Since the third elastic piece pin3 is elastically overlapped with the fifth elastic piece pin5, the fourth elastic piece pin4 is elastically overlapped with the sixth elastic piece pin6. For when the earphone socket 300 has the audio source plug 100 inserted, the third elastic piece pin3 and the fourth elastic piece pin4 are pushed away by the audio source plug 100, so that the third elastic piece pin3 is separated from the fifth elastic piece pin5, and the fourth elastic piece pin4 It is separated from the sixth shrapnel pin6, refer to FIG. 2(B). At this time, the audio signal received on the wireless interface cannot be transmitted to the speaker, and the speaker receives the audio signal transmitted from the audio source plug 100. Referring to FIG. 1(A), when the earphone socket 300 has the audio source plug 100 inserted, the second Pin1 and pin2 of the second shrapnel are connected to the ground terminal GND of the audio source plug 100, and the third shrapnel pin3 and the fourth shrapnel pin4 are respectively connected to the right channel RCE_R and the left channel RCE_L of the audio source plug 100 to realize single-ended output of the external audio source to the speaker .

The above-mentioned earphone socket 300 is designed with a mechanical switch, when the earphone plug 100 is inserted, the insertion of the earphone plug 100 can directly connect the third spring piece pin3 to the fifth spring piece pin5, the fourth spring piece pin4 to the The sixth shrapnel pin6 is separated to realize the access conversion of the wired audio source and the wireless audio source of the headphone jack. This method does not occupy the area of the circuit board, and has low cost and low power consumption.

The above-described embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still understand the foregoing The technical solutions recorded in each embodiment are modified, or some of the technical features are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention. .
