Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and in particular to a USB gaming earphone with dual sound card outputs. Background Art

[0002] As society progresses, people's demands are constantly increasing. Game enthusiasts, in particular, are increasingly demanding higher standards for their gaming equipment, demanding greater customization and personalization. Currently, gaming headsets on the market typically feature microphone and headphone volume control, EQ modes, and lighting effects, but only have a single speaker output device and recording input device mapped to the computer. This type of headset presents a problem for gaming enthusiasts: when playing online, users need to listen to both their own game background audio and the voices of their online teammates. Since the computer only has a single output device, it can't allocate separate volume for online teammates' voices and background audio. This also prevents separate adjustments for background audio and teammate voices. The inability to adjust the ratio of background audio to teammate voices results in loud headphone volume, resulting in both voice and background audio being loud, and the inability to quickly and freely control the ratio, which doesn't meet the functional requirements of enthusiasts. Therefore, a gaming headset with dual sound card outputs has been proposed to address this issue. Utility Model Content

[0003] In view of this, the present invention provides a USB gaming headset with dual sound card outputs, which solves the problems in the background technology that the existing gaming headsets on the market do not have the function of dual sound card outputs, cannot select output devices separately, and cannot proportionally adjust the volume of teammates' voices and game background sounds.

[0004] This utility model provides a USB gaming headset with dual sound card outputs, specifically comprising a main chip, an amp chip circuit, a microphone, and a master volume potentiometer. The main chip is equipped with at least two sound cards and is electrically connected to a mixing potentiometer and the microphone. The mixing potentiometer proportionally adjusts the output of the sound cards, then amplifies the left and right channel signals through the amp chip circuit, and then performs electro-acoustic conversion through the speakers. This technical solution can independently adjust the volume of background sound and teammates' voices in the game.

[0005] Furthermore, the microphone head is connected to the microphone input circuit, the microphone amplifying circuit, the microphone potentiometer, and the main chip in sequence.

[0006] More preferably, the main chip is also electrically connected to a microphone mute switch and a microphone noise reduction switch, wherein the microphone mute switch is used to control the mute switching of the microphone, and the microphone noise reduction switch is used to switch the noise reduction of the microphone.

[0007] More preferably, the main chip is connected to the external device via a USB connector.

[0008] Optionally, the main chip is also electrically connected to a light control chip and a light effect switching switch, and the light control chip is electrically connected to the lamp beads on the headset.

[0009] Further description of the above scheme, the main chip, headphone amplifier chip circuit, microphone mute switch, microphone noise reduction switch, and mixing potentiometer are all installed in the control box. The control box is also equipped with an EQ switch, lighting effect switch, total volume potentiometer, and microphone potentiometer. The EQ switch is used to switch the sound output mode, including movies, music, and games. The lighting effect switch is used to switch the lighting effects. The total volume potentiometer is used to adjust the overall volume output. The microphone potentiometer is used to adjust the microphone input.

[0010] Optionally, the main chip is connected to a wireless communication module and a rechargeable battery.

[0011] The gaming headset includes left and right ear shells connected by a head bow, a data cable, a control box installed on the data cable, a light control chip and lamp beads installed in the ear shells, a back clip is also provided on the back of the control box, and the main chip is also electrically connected to the indicator light.

[0012] Compared with the existing technology, the utility model sets two output sound card devices in the main chip, and the two sound card devices are connected to the mixing potentiometer. The proportion of the two output channels is adjusted by the mixing potentiometer, thereby realizing the adjustment of the sound volume ratio of different sound cards output; the utility model can select the output device separately, so that the proportion of game background sound and chat voice can be directly adjusted during the game and chat process, effectively preventing interference from other sounds; the main chip has multiple modes built-in, which can support voice changing effects (such as male to female, robot voice, baby voice, female to male, etc.), and also has multiple modes of atmosphere lighting effects to meet the personalized needs of current game enthusiasts; the main chip also has a USB-HID communication protocol, which can communicate with the computer or mobile device through the USB HID protocol for SDK (that is, host computer APP control and interaction), so that more personalized functions can be realized (such as: personalized customization of RGB atmosphere lights, multi-segment setting customization of EQ mode, microphone reverberation, microphone volume, microphone dynamic limitation and other more voice changing customizations).

[0028] In order to make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] See also Figure 1-9 As shown, the present invention provides a USB gaming headset with dual sound card outputs. Specifically, it includes a main chip, an earphone amplifier chip circuit, a microphone 3, and a master volume potentiometer 15. The main chip is equipped with at least two sound cards and is also electrically connected to a mixing potentiometer 11 and the microphone 3. The mixing potentiometer 11 proportionally adjusts the sound card outputs before amplifying the left and right channel signals through the earphone amplifier chip circuit and performing electro-acoustic conversion through the speaker. This technical solution allows for independent adjustment of the volume of background sound and teammates' voices during gaming. The microphone 3 is sequentially connected to the microphone input circuit, microphone amplifier circuit, microphone potentiometer, and main chip. In this embodiment, the main chip is also electrically connected to a microphone mute switch 12 for controlling the microphone mute mode and a microphone noise reduction switch 13 for switching the microphone noise reduction mode. The main chip is connected to external devices via a USB connector 2. The main chip is also electrically connected to a lighting control chip and a lighting effect switch 17, which are electrically connected to the lamp beads on the headset.

[0030] like Figure 1 、 2As shown, the main chip, headphone amplifier chip circuit, microphone mute switch 12, microphone noise reduction switch 13, and mixing potentiometer 11 are all installed in the control box 1. The control box 1 is also equipped with an EQ switch 14, a lighting effect switch 17, a master volume potentiometer 15, and a microphone potentiometer. The EQ switch 14 is used to switch the sound output mode, including movies, music, and games. The lighting effect switch 17 is used to switch lighting effects. The master volume potentiometer 15 is used to adjust the overall volume output. The microphone potentiometer is used to adjust the microphone input. The gaming headset includes left and right ear shells 4 connected by a head bow 5 and a data cable. The control box 1 is installed on the data cable. The ear shells 4 are equipped with a light control chip and lamp beads. The back of the control box 1 is also equipped with a back clip 16. The main chip is also electrically connected to the indicator light.

[0031] In other embodiments, the main chip is connected to a wireless communication module and a rechargeable battery. The wireless communication module is used to wirelessly connect to smart devices such as computers and mobile phones.

[0032] like Figure 5 As shown, the acoustic sensor inside the microphone core converts sound into an electrical signal. This signal then passes through C7 and C1 for RF filtering to prevent interference from high-frequency signals such as mobile phones, wireless mice, and wireless keyboards. The signal then passes directly to the end of the 3.5mm jack. The 3.5mm jack on the microphone stem is then plugged into the microphone socket inside the left ear shell 4. This signal passes through the PCBA inside the left ear shell, then through the inline remote to the control box 1. The signal then passes through the power supply circuit and is amplified within the chip, enabling microphone monitoring and USB uplink recording. The stem also features a mute indicator to indicate whether the microphone is recording or muted.

[0033] like Figure 6 、 7 As shown, U1 in the figure is a light control chip, whose main function is to control the data of the atmosphere light chip. By outputting SDB, SCL, and SDC data to the RGB light driver chip of the U3 chip, U3 then controls D1 to D12 to control the color of the output RGB light. At the same time, the light control chip receives the TX signal of the serial communication from the control box 1, which is convenient for the APP control on the PC, that is, the upper computer to control the atmosphere light. U1 sends the lighting effect mode data to the light control chip of the right ear shell 4 through the serial port TX to control the atmosphere light on the right end, and can also synchronize the lighting effect data to avoid the problem of inconsistent lighting effects on both sides due to the clock error problem inside the chip. At the same time, U1 is externally connected to the lighting effect switching switch 17, so that the lighting effect mode can be switched quickly.

[0034] like Figure 8As shown in the figure, U9 is the main chip, which is mainly responsible for connecting the USB D+, D-, VCC, and GND, processing the upstream signal, microphone upstream and music downstream communication. At the same time, it communicates with the PC for SDK interaction software. The U9 main chip can also map two output speaker devices and one recording device on the computer. The main chip is connected to the EQ switching switch 14, and the EQ modes include movies, music, and games. The main chip U9 is also connected to the microphone noise reduction switch 13. Press the microphone noise reduction switch 13 to turn the microphone noise reduction function on or off.

[0035] The main chip U9 is connected to the microphone mute switch 12. When the switch is in the on position, the microphone channel enters the mute state. The main chip's pin 22 outputs a high level through R8 and is connected to the microphone mute light. At the same time, the LED light at the microphone boom position lights up red. When the microphone mute switch J9 is turned off, the microphone enters the recording state (not muted), and the LED light at the microphone boom position turns off.

[0036] Main chip U9 is connected to the dual-sound card device's mixing potentiometer 11. Pin 1 of mixing potentiometer 11 is connected to the main chip's regulated 3.3V output pin, pin 3 is connected to ground, and pin 2 is the center tap. Sliding potentiometer RV3 generates different voltages, which are then output through pin 2. This voltage passes through an RC filter network composed of R30 and C46 to remove interference noise and AC ripple. The voltage then enters pin 23 of main chip U9, where it is detected by the internal ADC. Upon detecting the voltage level, the main chip U9's internal program adjusts the sound output ratio between sound cards 1 and 2 mapped on the computer. The adjusted sound ratio is then amplified and filtered internally, and the left and right stereo audio signals are output from pins 29 and 30 of the main chip, which are then connected to the headphone amplifier circuit unit. A USB cable connects to the power supply, which is then regulated and filtered by voltage regulator chip U7 before being supplied to main chip U9, ensuring stable operation.

[0037] After the main chip U9 converts the digital-to-analog signal through the internal DAC, the audio signal is output in stereo from the 29th and 30th pins of the main chip U9. Figure 9 The K1-A and K2-A potentiometers adjust the volume of the headphone output, and then after coupling through C122 and C123, it enters the 9th and 15th pins of the headphone amplifier chip U15 through the R81 and R84 resistors. After being amplified and inverted by the amplifier, it is output from the 10th and 13th pins of the headphone amplifier chip U15. Figure 9C5 and C1 are capacitors used to prevent self-oscillation in the amplifier's feedback circuit. Feedback resistors R82 and R83 determine the amplifier's amplification factor. The amplifier's chip outputs the signal directly to the headphone jack, where it drives the speaker to produce sound. This chip supports 0V output, eliminating the need for a DC-blocking capacitor and improving the product's low-frequency response.

[0038] In actual use, the gaming headset of the present invention is connected to a computer via USB connector 2. At this time, the computer will map the information of two sound cards. In this embodiment, the devices output by the two sound cards are named Game device and Chat device respectively. The Game device is the device that outputs background sound during the game, and the Chat device is the device that outputs voice chat between teammates during the game. When playing games online, the game background sound is selected as the output sound card device - Game device, and the teammate voice sound output device is selected as Chat device. After this setting, the volume ratio of GAME and CHAT can be adjusted by the mixing potentiometer 11 on the microphone.
