[0035] The invention provides an earphone connector.

[0036] like Figure 1 As shown, Figure 1 The present invention is a schematic diagram of a module in which an embodiment of a headphone connector 20 of the present invention is connected to an audio device 10 and a headphone 30. In this embodiment, the headphone connector 20 has a signal input end and a signal output end, the signal input end is connected to the audio device 10, and the signal output end is connected to the headphone 30. The headphone connector 20 includes a shell (not shown), an audio input module 100 disposed in the shell, an audio switching switch 200 disposed on the shell, and a control module 300 disposed in the shell, wherein the audio input module 100 is provided with the signal input end; the audio switching switch 200 is used to respond to user operations and output an audio switching signal; the audio input module 100 and the audio switching switch 200 are respectively connected to the control module 300; the control module 300 is used to simultaneously output the audio data and voice data of the audio device 10 to the speaker of the headphone 30 when the audio switching signal is received; and output the audio data of the audio device 10 to the speaker of the headphone 30 when the audio switching signal is not received.

[0037] It should be noted here that voice data refers to the sound signal emitted by the user, which is collected by the headphone connector 20 or the headphone 30 and output to the speaker of the headphone 30. Specifically, when the control module 300 receives the audio switching signal, the headphone connector 20 and the headphone 30 enter the karaoke mode, and the voice data is the signal formed after the sound of the user singing the song is collected by the pickup module on the headphone connector 20 or the pickup module on the headphone 30; the audio data of the audio device 10 is a piece of music output by the audio device 10.

[0038] In this embodiment, the audio device 10 is used to send audio data. The audio device 10 can be a mobile phone, a computer, a television, etc. The audio input module 100 is used to receive audio data sent by the audio device 10. The audio input module 100 can be a connector adapted to the TYPE-C interface or the lightning interface of the mobile phone. The lightning interface is also called the lightning interface, which is used to adapt to Apple mobile phones. Correspondingly, the audio device 10 can be different types of mobile phones or computers or electronic devices with music playback functions such as MP3, Ipod, etc., such as Android phones, Apple phones, etc. The connector is matched and connected to the audio device 10, and the specific type is not limited.

[0039] It should be noted here that the headphone connector 20 also has an audio output module (not shown in the figure), and the audio output module is configured with the signal output end. The signal output end and the headphone 30 can be plugged in or wirelessly connected through Bluetooth, WiFi, etc.; specifically, in this embodiment, the signal output end is a 3.5mm headphone jack, and the headphone 30 is plugged into the signal output end of the headphone connector 20. In this way, the karaoke function can be achieved through ordinary headphones; in other embodiments, the signal output end can also be a TYPE-C interface or a lightning interface to adapt to more types of headphones.

[0040] It should be emphasized here that the advantage of this patent compared with karaoke APPs (such as Changba, Kugou, etc.) is that this patent not only saves the steps of installing various APPs through the optimization of hardware structure, but also has a wider range of applicability. For example, it can be applied to laptops, desktops, MP3s and other audio devices that can play music but cannot install APPs; in addition, since the headphone connector 20 can be adapted to various types of headphones 30 on the market, ordinary headphones 30, especially headphones 30 that originally do not have a sound pickup module, can realize the karaoke function after being connected to the audio device 10 through the headphone connector 20 proposed by this patent, which is very convenient to use.

[0041] The audio switching switch 200 is used to respond to user operations and output an audio switching signal to the control module 300 to achieve the function switching between the non-K song mode and the K song mode. The audio switching switch 200 can be a dial switch, a touch switch, a touch switch, etc., which is not specifically limited here. In a specific embodiment, Figures 1 to 3 As shown, the audio switching switch 200 is a first touch button K1, a first end of the first touch button K1 is grounded, and a second end of the first touch button K1 is connected to the first signal end GPIO6 of the audio codec chip U1. After the user touches the audio switching switch 200, the audio switching switch 200 outputs an audio switching signal to the control module 300, and the control module 300 controls the earphone 30 to switch from the non-K song mode to the K song mode. When the audio switching switch 200 is touched again, the earphone 30 switches from the K song mode back to the non-K song mode. The non-K song functions include call function, music listening function, broadcast function, etc.

[0042] The control module 300 is used to perform data processing such as digital-to-analog conversion, analog-to-digital conversion, and encoding and decoding on the received audio data and voice data. In a specific embodiment, the control module 300 is an audio codec chip U1, such as Figure 3As shown, the type of audio codec chip is not specifically limited, and it can be an ALC series chip. The seventh signal terminal DM of the audio codec chip U1 is connected to the left channel signal terminal DM of the headphone 30 connector, and the eighth signal terminal DP of the audio codec chip U1 is connected to the right channel signal terminal DP of the headphone 30 connector. The audio data of the audio device 10 is received through the left channel signal terminal DM and the right channel signal terminal DP of the headphone 30 connector.

[0043] When receiving the audio switching signal, the audio codec chip U1 controls the earphone 30 to switch from the non-Karaoke mode to the Karaoke mode, processes the audio data of the audio device 10 and the user's voice data, and outputs them to the speaker of the earphone 30 at the same time, and the speaker of the earphone 30 plays the audio data of the audio device 10 and the user's voice data;

[0044] When the audio switching signal is not received, the audio codec chip U1 controls the earphone 30 to switch from the karaoke mode to the non-karaoke mode or maintain the non-karaoke mode, and outputs the audio data of the audio device 10 to the speaker of the earphone 30, and the speaker of the earphone 30 plays the audio data of the audio device 10;

[0045] For example, when a user wants to enter a karaoke mode from the state of listening to Jay Chou's song "Nunchucks", the user inputs an audio switching signal to the audio codec chip U1, and the audio codec chip U1 controls the earphone 30 to switch from a non-karaoke mode to a karaoke mode. At this time, the audio device 10 can process the audio data of the song "Nunchucks" and the voice data of the user singing "Nunchucks" and output them to the speaker of the earphone 30 at the same time. In this way, the user can clearly hear the voice data of his or her singing and the audio data of "Nunchucks" from the speaker of the earphone 30 in the karaoke mode.

[0046] It should be noted here that the audio data may include the original singer or may not include the original singer. Taking the song "Nunchucks" as an example, the song "Nunchucks" includes the voice data and music accompaniment sung by singer Jay Chou. The audio data including the original singer means that the audio data is the voice data and music accompaniment sung by singer Jay Chou, and the audio data not including the original singer means that the audio data is only the music accompaniment.

[0047] It should be noted here that the earphone 30 is a broad concept, including earplugs, ordinary earphones 30, wired earphones 30, etc., or also includes an amplifier circuit for power amplification, a filter circuit for filtering out clutter, etc.

[0048] Further, in another embodiment of the present application, Figure 4As shown, the headphone connector 20 further includes a sound effect selection switch 400, which is connected to the control module 300. The sound effect selection switch 400 is used to respond to user operations and output a sound effect selection signal to the control module 300; the control module 300 is also used to adjust the output sound effect of the headphone 30 according to the sound effect selection signal. Specifically, in the listening or karaoke mode, the user can also switch the sound effect of the audio data of the audio device 10 by controlling the action of the sound effect selection switch 400. For example, after the user opens the listening software (such as Kugou Music, QQ Music, etc.), the sound effect selection switch 400 is used to select the output sound effect of the audio data, such as 3D beautiful sound, super bass, pure human voice, vinyl record and other different sound effects, so as to improve the user's listening or karaoke experience.

[0049] Similarly, the sound effect selection switch 400 can be a touch button, or a knob switch, etc., and the sound effect is selected by touching or rotating. The type of the sound effect selection switch 400 is not specifically limited. In one embodiment, the sound effect selection switch 400 is a second touch button K2, and the first end of the second touch button K2 is grounded, and the second end of the second touch button K2 is connected to the second signal terminal GPIO7 of the audio codec chip.

[0050] Further, in yet another embodiment of the present application, Figure 5 As shown, the earphone connector 20 further includes a sound pickup module 500 , which is connected to the control module 300 , and is used to obtain the user's singing voice to form the voice data.

[0051] Specifically, the sound pickup module 500 is used to pick up voice data sent by the user. In this embodiment, the sound pickup module 500 is a microphone MIC, and the microphone is provided with a first signal end and a second signal end. The first signal end of the microphone is connected to the third signal end SLEEVE of the audio codec chip, and the second signal end of the microphone is connected to the fourth signal end RING2 of the audio codec chip. The voice data sent by the user when making a phone call or singing passes through the microphone MIC. The microphone MIC converts the sound into an electrical signal through the vibration of the eardrum, and outputs it to the audio codec chip U1 through the third signal end SLEEVE of the audio codec chip and the fourth signal end RING2 of the audio codec chip. The audio codec chip U1 receives the electrical signal of the microphone MIC and performs digital-to-analog conversion, analog-to-digital conversion and encoding and decoding, and then outputs the audio data to the speaker of the headset 30 or another audio device 10, thereby realizing karaoke or non-karaoke function.

[0052] However, the design of this patent is not limited to this. In other embodiments, the pickup module 500 may not be set on the headphone connector 20, and a wire-controlled headset 30 is used. Since the wire-controlled headset 30 has a microphone, the function of sound pickup can also be achieved. At this time, the voice data is the user's singing voice obtained by the wire-controlled headset 30.

[0053] The specific working principle of the earphone connector 20 is as follows:

[0054] When the user needs to realize non-Karaoke functions (including listening to songs or making phone calls) through the headphone connector 20, the headphone 30 and the audio device 10, without touching the touch button K1, in the listening mode, the audio data output by the audio device 10 is sent to the audio codec chip U1, and the audio data is output to the speaker of the headphone 30 for playback after audio coding and data processing. In the call mode, the audio data output by the audio device 10 is sent to the audio codec chip U1, and the audio data is output to the speaker of the headphone 30 for playback after audio coding and data processing. At the same time, the voice data sent by the user is output to the audio codec chip U1 through the microphone MIC, and the voice data is output to the audio device 10 after audio coding and data processing, thereby realizing the call function.

[0055] When the user needs to realize the karaoke function through the headphone connector 20, the headphone 30 and the audio device 10, the user touches the touch button K1, and the touch button K1 outputs an audio switching signal. The codec chip U1 obtains the user's voice data picked up by the microphone MIC, and outputs it to the speaker of the headphone 30 after encoding and decoding and data processing. At the same time, the audio data output by the audio device 10 is processed by the audio codec chip U1 and output to the speaker of the headphone 30. The user can hear the audio data output by the audio device 10 and the voice of the user at the same time, thereby realizing the karaoke function, improving the karaoke experience, and solving the problem that the user cannot hear his own voice clearly when singing karaoke through the headphone 30.

[0056] Furthermore, in an embodiment of the present patent, the headphone connector also includes a volume adjustment switch 600, and the volume adjustment switch 600 is connected to the control module. When the control module is in the karaoke mode, the volume adjustment switch 600 is used to adjust the volume of the voice data when the headphone is played; when the control module is in the non-karaoke mode, the volume adjustment switch 600 is used to adjust the volume of the audio data when the headphone is played. In this way, in the non-karaoke mode, the volume adjustment switch 600 can be used to adjust the volume of the music played by the audio device, and in the karaoke mode, the volume adjustment switch 600 can be used to adjust the volume of the user's singing, thereby meeting the needs of users with different hearing abilities, so that different users can hear their own singing clearly.

[0057] This patent also proposes a karaoke set, which includes headphones 30 and the headphone connector 20. The signal input end of the headphone connector 20 is used to connect the audio device 10, and the signal output end of the headphone connector 20 is used to connect the headphones 30. Since the karaoke set proposed by this patent adopts all the technical solutions of the above-mentioned embodiment of the headphone connector 20, it has all the beneficial effects of the above-mentioned solutions, which will not be repeated here.

[0058] It should be noted here that, in this embodiment, the earphone 30 and the earphone connector 20 are arranged in a separate structure, so the same earphone connector 20 can also be used in conjunction with other earphones 30; in other embodiments, the earphone connector 20 and the earphone 30 can also be arranged as an integrated structure.

[0059] Furthermore, in order to improve the effect of listening to songs or making calls, the headset 30 includes a first speaker HP1 and a second speaker HP2. In one embodiment, the first speaker HP1 is a left earphone, and the second speaker HP2 is a right earphone. The signal end of the first speaker HP1 is connected to the fifth signal end HPOUT-L of the audio codec chip U1, and the signal end of the second speaker HP2 is connected to the sixth signal end HPOUT-R of the audio codec chip U1. The audio codec chip also includes multiple test pins SPI, ground pin AGND, power pin D3V3, data pin SDA, clock pin SCL, etc. Each pin can be connected and set its specific function according to specific needs, and no specific restrictions are made here.

[0060] Further, the connection method between the earphone 30 and the signal output end of the earphone connector 20 is now described. In this embodiment, the earphone interface can be a 3.5 / 2.5mm earphone jack, or a TYPE-C interface or a lightning interface, or a USB-A interface for pluggable connection of earphones 30 with different connectors. In other embodiments, the earphone 30 can also be wirelessly connected to the earphone connector 20. Similarly, in this embodiment, the signal input end of the earphone connector 20 is plugged into the audio device 10, such as the TYPE-C interface of the mobile phone. In other embodiments, the earphone connector 20 can also be wirelessly connected to the audio device 10 through Bluetooth or other methods.

[0061] like Figure 7 As shown, the signal output terminal includes an earphone interface. The earphone interface is used to connect to the earphone 30, and the plug of the earphone 30 is inserted into the earphone interface, so that the earphone 30 is connected to the audio device 10 through the earphone connector 20 of the present application.

[0062] When the earphone 30 interface is a 3.5 / 2.5mm earphone jack, the earphone interface includes a left channel contact terminal, a right channel contact terminal, a microphone contact terminal and a ground terminal; the earphone connector 20 includes an earphone switching module 600, the earphone switching module 600 can detect the type of the earphone plug inserted into the earphone interface, and the earphone switching module 600 can make the microphone contact terminal and the ground terminal in the earphone interface interchangeable. In the earphone 30 used daily, the plug of the earphone 30 includes the American standard and the Chinese standard. Among them, the ground terminal and the microphone contact terminal in the American standard earphone plug are exactly opposite to the positions of the ground terminal and the microphone contact terminal in the Chinese standard earphone plug. In the present application, the earphone interface also includes a left channel contact terminal, a right channel contact terminal, a microphone contact terminal and a ground terminal, which are in one-to-one correspondence with the left channel contact terminal, the right channel contact terminal, the microphone contact terminal and the ground terminal of the earphone 30 plug. When the plug of the earphone 30 is inserted into the earphone jack, the earphone switching module 600 detects the type of the earphone and adjusts the microphone contact terminal and the ground terminal in the earphone jack accordingly according to the type of the earphone to match the earphone 30. Figure 8 The circuit diagram shown is a circuit diagram of a specific embodiment of a headphone interface.

[0063] The signal output terminal includes at least two earphone interfaces, which means that the earphone connector 20 can be connected to at least two earphones 30 at the same time, so that two users can listen to the music of the audio device 10 at the same time, which is more entertaining.

[0064] The earphone connector 20 also includes a voice changing module 700, which is connected to the control module 300. When the voice changing module 700 is in the on state, the voice changing module 700 can receive the user voice data in the control module 300, and transmit the user voice data back to the control module 300 after the voice changing process is performed. It should be understood that the voice changing module 700 processes the user's voice data. In this way, when the control module 300 is in the karaoke mode, the voice changing module 700 can perform voice changing process on the user's voice data, and the processed user's voice data is transmitted to the speaker of the earphone 30 through the control module 300. Among them, a voice changing touch switch can be even provided on the earphone connector 20, and the state of the voice changing module 700 can be changed by the switch, for example, the voice changing module is turned on, and the voice changing mode of the voice changing module 700 can also be changed, such as changing the user's voice into human voice, robot voice, male voice into female voice, female voice into male voice and other modes.

[0065] The signal input end is one of a TYPE-C connector, a lighting connector, a miniUSB connector, and a USB-A connector. A charging interface 800 is provided on the headphone connector 20, and the charging interface 800 is connected to the signal input end for transmitting current, and current can be transmitted between the signal input end and the audio device 10. In this way, when the signal input end of the headphone connector 20 is connected to the audio device 10, the charging interface 800 on the headphone connector 20 can also be connected to the charger at the same time. In this way, when the audio device 10 is a mobile phone, through the headphone connector 20, you can listen to music and charge the mobile phone, which is more practical. Among them, the charging interface 800 includes at least one of a TYPE-C interface, a lighting interface, a miniUSB interface, and a USB-A interface.

[0066] The headphone connector 20 is provided with an IC module, in which the PD and QC protocols are provided, and the IC module is connected to the circuit of the charging interface, and the IC module is connected to the circuit of the signal input terminal 10, so that the headphone connector 20 can transmit current and audio data at the same time. Through the above-mentioned IC module, the headphone connector can charge an audio device 10 such as a mobile phone while listening to music or singing karaoke.

[0067] The control module 300 also includes a first mode. When the control module 300 is in the first mode, the control module 300 transmits the user's voice data to the speaker so that the speaker plays the user's voice data. The audio switching switch 200 is used to switch the control module 300 between the karaoke mode, the non-karaoke mode and the first mode. In this way, when the control module 300 is in the first mode, only one's own voice can be heard in the speaker, so that the user can avoid interference from other sounds when singing and can better evaluate his or her own singing.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
