[0001] This utility model relates to the field of audio cables, and in particular to a smart connection cable. Background Technology

[0002] Audio cables are used to connect playback devices to musical instruments, transmitting the audio signals from the instrument during use to the playback settings. Before use, the instrument needs to be tuned. In current technology, a tuner is usually purchased separately and clipped onto the outside of the instrument to calibrate the strings before use, which is inconvenient during use. Utility Model Content

[0003] Therefore, it is necessary to provide a smart connection cable to address the problems in the existing technology.

[0004] A smart connector cable, characterized in that it comprises a wire harness with connector terminals at both ends. The light-emitting part is fixed to the outside of the wire harness and includes an LED light strip, an LED light-emitting device, or an optical fiber, with a light source at the end of the optical fiber. The sound pickup and dimming structure is fixed on the outside of the wire harness and includes a sound pickup structure and a dimming structure. The pickup structure is used to pick up the pitch of the instrument strings during the tuning process; The dimming structure includes a control structure that controls the electrical connection or disconnection between the light-emitting part and the power supply, and controls the light color of the LED light strip or the light color of the LED light-emitting device or the light color of the optical fiber through the light source according to the tone picked up by the sound pickup structure.

[0005] In one embodiment, the pickup structure includes a pickup, which is a microphone or MIC, used to pick up the pitch of the instrument strings during the tuning process.

[0006] In one embodiment, the control structure includes an MCU chip, the microphone is electrically connected to the MCU chip via an audio amplification circuit, and the MCU chip is electrically connected to the light-emitting part.

[0007] In one embodiment, the control structure further includes a tactile switch for adjusting the control structure to a tuning mode or a rhythm mode. The tuning mode is in which the control structure controls the color of the light emitted by the light-emitting part according to the pitch picked up by the sound pickup structure. The rhythm mode is in which the control structure controls the color of the light emitted by the light-emitting part according to the musical rhythm of the sound pickup structure.

[0008] In one embodiment, during the tuning mode, the measured frequency picked up by the pickup structure is compared with the standard music frequency. When there is a deviation between the measured frequency and the standard music frequency, the light-emitting part displays a first color. When different strings are adjusted, the first color corresponds to different colors. When the measured frequency is the same as the standard music frequency, the light-emitting part displays a second color.

[0009] In one embodiment, during the rhythmic mode, the light-emitting part flashes at a preset frequency or flashes in sync with the rhythm of the music.

[0010] In one embodiment, the light-emitting portion is linearly distributed on the outside of the wire bundle or wound around the outside of the wire bundle.

[0011] In one embodiment, the audio pickup and dimming structure further includes a power switch for connecting or disconnecting the MCU from the power supply.

[0013] A tuning method, employing the aforementioned intelligent connection cable, is characterized by comprising: Connect the playback device to the instrument using an audio cable. Turn on the power switch to connect the MCU chip to the power supply. Switching to tuning mode via a touch switch and plucking the instrument strings compares the measured frequency picked up by the pickup structure with the standard music frequency. When there is a deviation between the measured frequency and the standard music frequency, the light-emitting part displays the first color, and thus the light-emitting part on the outside of the wire harness displays the first color. Adjusting the string tension until the measured frequency is the same as the standard music frequency, at which point the light-emitting part displays the second color, and thus the light-emitting part on the outside of the wire harness displays the second color.

[0014] In one embodiment, after adjusting the measured frequency of all the strings, the light-emitting part is switched to rhythm mode by a touch switch, and the light-emitting part flashes at a preset frequency or flashes in rhythm with the music.

[0015] The aforementioned smart cable places the sound pickup and dimming structure on the outside of the audio cable. During use, the sound pickup structure picks up the measured frequency of the instrument and compares it with the standard music frequency, thus enabling tuning. During tuning, the color of the light-emitting part on the outside of the cable can be used to determine whether the tuning is accurate, allowing for better observation of the tuning process. After tuning is complete, the color of the light-emitting part can be controlled to change synchronously with the music, thereby improving the user experience of the audio cable.

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 2 As shown, a smart connection cable is characterized by comprising a wire harness 1, with connection terminals at both ends. The light-emitting part 2 is fixed to the outside of the wire harness 1 and includes an LED light strip or an LED light-emitting device or an optical fiber, with a light source at the end of the optical fiber; The sound pickup and dimming structure 3 is fixed on the outside of the wire harness 1, and includes a sound pickup structure and a dimming structure; The pickup structure is used to pick up the pitch of the instrument strings during the tuning process; The dimming structure includes a control structure that controls the electrical connection or disconnection between the light-emitting part and the power supply, and controls the light color of the LED light strip or the light color of the LED light-emitting device or the light color of the optical fiber through the light source according to the tone picked up by the sound pickup structure.

[0021] The pickup and dimming structure 3 is placed on the outside of the audio cable. During use, the actual frequency of the instrument is picked up by the pickup structure and compared with the standard music frequency, so that the sound can be tuned. During the tuning process, the color of the light-emitting part 2 on the outside of the cable bundle 1 can be used to judge whether the tuning is accurate. This allows for better observation of the tuning process. After the tuning is completed, the color of the light-emitting part 2 can be controlled to change synchronously with the music, thereby improving the user experience of the audio cable.

[0022] At this time, in order to pick up the sound of the instrument during the performance through the pickup structure, the pickup structure includes a pickup, which is a microphone or MIC head, used to pick up the pitch of the instrument strings during the tuning process.

[0023] In order to convert the picked-up music vibrations into electrical signals and process them, in this embodiment, the control structure includes an MCU chip, the microphone is electrically connected to the MCU chip through an audio amplification circuit, and the MCU chip is electrically connected to the light-emitting part.

[0024] The pickup structure, MCU chip, and audio amplifier circuit all adopt existing technical solutions, so they will not be described in detail here.

[0025] After setting the light-emitting parts 2 distributed on the outside of the wire harness 1, the color change of the light-emitting parts 2 can be used not only to indicate the tuning status during tuning, but also to move in rhythm with the music after tuning, thus having a certain aesthetic effect and enhancing the user experience. At this point, it is necessary to separate the two states. Specifically, the control structure also includes a touch switch, which is used to adjust the control structure to either tuning mode or rhythm mode. In tuning mode, the control structure controls the light color of the light-emitting parts according to the pitch picked up by the pickup structure. In rhythm mode, the control structure controls the light color of the light-emitting parts according to the musical rhythm of the pickup structure. Different modes can be switched directly via the touch switch, allowing the user to rotate the device according to their actual needs during use. Of course, other methods can also be used to switch modes. For example, in tuning mode, after all the strings are tuned, the device automatically switches to rhythm mode, reducing the user's actual operation and making it more convenient to use.

[0026] Specifically, in the tuning mode, the measured frequency picked up by the pickup structure is compared with the standard music frequency. When there is a deviation between the measured frequency and the standard music frequency, the light-emitting part displays a first color. When adjusting different strings, the first color corresponds to different colors. When the measured frequency is the same as the standard music frequency, the light-emitting part displays a second color. At this time, since there are multiple strings, each string corresponds to a color when adjusted. That is, the first color is set according to the string. In this way, during the adjustment process, it is clear which string is being adjusted, and it is not easy to make mistakes. In the prior art, different numbers / letters need to be displayed on the screen to identify the string, and the color displayed on the screen is also needed to judge the tuning status. In this application, the string is distinguished by the color of the light-emitting part 2, which makes the overall structure simpler. During use, the string and the tuning status can be determined by directly observing the color of the light-emitting part 2.

[0027] Specifically, in the rhythm mode, the light-emitting part flashes at a preset frequency or flashes in rhythm with the music. During use, if switched to rhythm mode, the light-emitting part flashes at a preset frequency or flashes in rhythm with the music, so that the light-emitting part 2 on the outside of the wire harness 1 can also flash, thereby achieving a certain aesthetic effect.

[0028] The light-emitting part 2 is positioned on the outside of the wire bundle 1 so that its color can be observed. In this case, the light-emitting part 2 is either linearly distributed or coiled around the outside of the wire bundle 1. However, when using optical fiber as the light-emitting part, the surface of the optical fiber needs to be scratched to allow light to pass through the outer surface, thus enabling light transmission across the entire outer side of the optical fiber and achieving a better aesthetic effect.

[0029] At this point, the light source is placed at the end of the housing, the optical fiber extends into the housing, and the light source is located on the side of the optical fiber. In this way, the light emitted by the light source can be transmitted through the optical fiber during use, thereby displaying different colors.

[0030] In order to achieve multiple colors, LED lights are used as the light source. By controlling the LED lights, multiple different colors of light can be emitted, so that different colors can be observed on the outside of the wire harness 1.

[0031] Alternatively, LED light strips or LED light-emitting devices can be used as the light-emitting part and placed on the outside of the wire harness, which can also achieve the purpose of color reminder and a certain aesthetic effect.

[0032] Of course, at this time, the sound pickup and dimming structure 3 also includes a power switch for connecting or disconnecting the MCU from the power supply. By setting the power switch, the connection or disconnection of the sound pickup and dimming structure 3 to the power supply can be controlled, so that the power switch can be turned on for use when needed. Of course, when it is not needed, the sound pickup and dimming structure 3 can also be turned off by the power switch, so that there is no need for tuning or lighting effects during use. At the same time, the sound pickup and dimming structure 3 also includes a housing, which is fixed to the outside of the wire harness 1, and the sound pickup and dimming structure 3 is located inside the housing.

[0033] The sound pickup and dimming structure also includes an earphone connection jack, a sound effect switching button, an OTG internal recording button, a tone adjustment button, and an equalizer button; the sound pickup and dimming structure also includes several sound effect indicator lights.

[0034] The headphone jack is used to connect headphones and for headphone monitoring during use, specifically in scenarios such as recording, stage performances, and broadcasting. After the headphones are plugged into the headphone jack, the audio signal is monitored in real time. Since the signal is transmitted directly from the audio cable to the headphones, the original audio signal can be presented as realistically as possible, avoiding distortion caused by sound coloration.

[0035] For the sound effect switching button, the sound pickup and dimming structure has a corresponding sound effect module. During use, you can switch between different sound effect modes using the sound effect button. Correspondingly, to facilitate observation of the available sound effect modes, the sound pickup and dimming structure also has several sound effect indicator lights, such as reverb and chorus. Pressing the sound effect switching button will turn on the sound effect switching module. Pressing the sound effect switching button again will switch to different sound effect modes in sequence. Pressing the sound effect switching button again will turn it off.

[0036] For the OTG internal recording button, a corresponding internal recording module (using existing technology) is provided in the audio pickup and dimming structure. The mobile phone is connected to the headphone jack through the OTG adapter cable. This allows internal recording to be achieved through the mobile phone, directly transmitting the audio signal to the mobile phone and avoiding the impact of ambient noise on the recording effect.

[0037] For the tone adjustment button, there is a corresponding tone adjustment module (using existing technology) in the pickup and dimming structure. The tone can be adjusted by using this button.

[0038] For the equalizer button, there is a corresponding equalizer module (using existing technology) inside the audio pickup and dimming structure, and audio adjustment can be achieved through this button.

[0039] At this point, since it is necessary to adjust the timbre, audio, and switch sound effects, that is, at this time, the audio signal needs to be adjusted. In this embodiment, the pickup and dimming structure is not simply placed on the outside of the audio cable, but the audio cable is connected to the circuit board. The circuit board is equipped with the corresponding equalizer module, sound effect module, and timbre adjustment module. Then the circuit board is connected to the connection terminal. In this way, the audio data transmitted by the audio cable will pass through the circuit board, and can be adjusted by the corresponding button.

[0040] At this time, the entire sound pickup and dimming structure is located close to the connection terminal, that is, the outer shell of the sound pickup and dimming structure is directly set together with the connection terminal. In this way, the light-emitting part is mainly distributed on the outside of the wire harness. This way, regardless of whether the audio line and the circuit board are designed separately (without electrical connection) or the audio line and the circuit board are electrically connected, the light-emitting part of the wire harness can be controlled, thereby realizing the display of the tuning status.

[0041] A tuning method, employing the aforementioned intelligent connection cable, is characterized by comprising: Connect the playback device to the instrument using an audio cable. Turn on the power switch to connect the MCU chip to the power supply. Switching to tuning mode via a touch switch and plucking the instrument strings compares the measured frequency picked up by the pickup structure with the standard music frequency. When there is a deviation between the measured frequency and the standard music frequency, the light-emitting part displays the first color, and thus the light-emitting part 2 on the outside of the wire harness 1 displays the first color. Adjusting the string tension until the measured frequency is the same as the standard music frequency, at which point the light-emitting part displays the second color, and thus the light-emitting part 2 on the outside of the wire harness 1 displays the second color.

[0042] During use, first connect the instrument to the playback device (such as a speaker) via an audio cable, then turn on the power switch, and then switch to the tuning mode by touching the switch. In this mode, tune the instrument. During the tuning process, you can judge the position of the string and the tuning status by observing the color of the light-emitting part 2 on the outside of the wire harness 1, thereby ensuring the tuning effect. Since different strings correspond to different colors of the light-emitting part 2, you can determine the specific string and its tuning status during the tuning process by observing the specific color.

[0043] After adjusting the measured frequencies of all strings, switch to rhythm mode via a touch switch. The light-emitting part will then flash at a preset frequency or flash in rhythm with the music. In addition to actively switching via the touch switch, users can also switch to rhythm mode based on preset conditions. For example, in tuning mode, using a preset instrument time will directly enter rhythm mode. This active switching to rhythm mode makes it more convenient for users.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
