[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4 The utility model provides a passive single-channel guitar signal converter, including a signal converter body 1, an input end interface 2 and an output end interface 3. A cover plate 4 is provided on the upper part of the signal converter body 1, and a circuit board 5 is provided inside the signal converter body 1. A connecting mechanism 6 is provided inside the signal converter body 1 for installing and positioning the cover plate 4 on the upper part of the signal converter body 1, and installing the circuit board 5 in the signal converter body 1 at the same time. The input end interface 2 and the output end interface 3 are electrically connected to the circuit board 5 respectively. A heat conducting block 7 is provided at the bottom of the circuit board 5 for conducting heat to the circuit board 5. The bottom of the heat conducting block 7 is connected to a mounting plate 8 and is fixedly installed on the bottom of the signal converter body 1. A plurality of heat sinks 9 are fixedly connected to the bottom of the heat conducting block 7 and are evenly distributed.

[0024] The circuit board 5 includes a signal amplification circuit, a filtering circuit and an impedance matching circuit.

[0025] Signal amplification circuit: uses low-noise, high-stability amplification components to ensure that the signal is not distorted during the amplification process.

[0026] Filter circuit: Reasonably designed filter circuit effectively removes high-frequency noise and interference, improving sound quality.

[0027] Impedance matching circuit: Design a matching impedance circuit based on the input impedance of the audio device to ensure the stability and high fidelity of signal transmission.

[0028] When the guitar signal enters the signal converter body 1 through the input interface 2, it is first amplified by the signal amplifier circuit, then passes through the filtering circuit to remove high-frequency noise and interference, and finally passes through the impedance matching circuit to match the input impedance of the audio device to ensure the stability and high fidelity of signal transmission.

[0029] According to the above working process, it can be seen that: through the provided connecting mechanism 6, the cover plate 4 can be conveniently installed on the upper part of the signal converter body 1, and it is also convenient to disassemble it. Not only can the circuit board 5 be stably installed and limited inside it, but it can also be conveniently maintained and replaced, thereby improving the practicality of the device.

[0030] Further as Figure 2 、 Figure 3 and Figure 4As shown, it is worth mentioning that four connecting mechanisms 6 are provided in the signal converter body 1, and the four connecting mechanisms 6 are provided near the four corners of the signal converter body 1. The connecting mechanism 6 includes a support column 601, and the support column 601 is fixedly connected to the upper surface of the mounting plate 8 at the bottom of the signal converter body 1. The upper end of the support column 601 is fixedly connected to a connecting rod 602, and the upper end of the connecting rod 602 is fixedly connected to a clamping platform 604. A connecting cylinder 605 is movably provided on the outside of the clamping platform 604. The top end of the connecting cylinder 605 is fixedly connected to the bottom of the cover plate 4, and the bottom surface of the connecting cylinder 605 is fixedly connected to a second elastic gasket 606. The circuit board 5 is provided on the first elastic gasket 603 and the second elastic gasket through the connecting rod 602. Between the pieces 606, the diameter of the connecting rod 602 is smaller than that of the support column 601, and the upper part of the support column 601 forms a stepped platform through the connecting rod 602. The clamping platform 604 is set in a truncated cone and protrudes from the outer surface of the connecting rod 602. The inner side of the connecting tube 605 is matched with the clamping platform 604. A movable groove 607 is opened on the inner wall of the connecting tube 605 below the clamping platform 604, and a positioning rod 608 is slidingly arranged in the movable groove 607. The positioning rod 608 is fixedly installed with a spring 609 on one side of the movable groove 607. There are four movable grooves 607 in the wall of the connecting tube 605 and are evenly distributed. The positioning rod 608 is set in an arc-shaped surface near one end of the connecting rod 602 and is arranged below the clamping platform 604 through the movable groove 607.

[0031] When in use, the cover plate 4 is connected and matched with the clamping platform 604 through the connecting tube 605 at the bottom thereof. When the clamping platform 604 slides in the connecting tube 605, the positioning rod 608 is squeezed, so that it slides in the movable groove 607. When the clamping platform 604 slides above the positioning rod 608, the positioning rod 608 slides under the elastic force of the spring 609 to limit the clamping platform 604. The elastic force of the first elastic gasket 603 and the second elastic gasket 606 can keep the circuit board 5 stably installed and fixed in the signal converter body 1, thereby improving its installation stability and facilitating its disassembly for later maintenance and replacement, thereby improving the practicality of the device.

[0032] This solution has the following working process: when the device is used, the circuit board 5 is limitedly installed in the signal converter body 1 by matching the connecting rod 602 and the clamping platform 604. At the same time, the bottom of the circuit board 5 contacts the upper part of the heat-conducting block 7, so that the heat generated on the circuit board 5 is transferred during use and the circuit board 5 is dissipated, thereby achieving heat dissipation through the heat sink 9. In addition, the input end interface 2 and the output end interface 3 are electrically connected to the two sides of the circuit board 5 respectively, so as to facilitate the use of the device. At this time, the cover plate 4 is connected and matched with the clamping platform 604 through the connecting tube 605 at the bottom thereof. When the clamping platform 604 slides in the connecting tube 605, it squeezes the positioning rod 608, causing it to slide in the movable groove 607. When the clamping platform 604 slides above the positioning rod 608, the positioning rod 608 slides under the elastic force of the spring 609 to limit the clamping platform 604. In addition, through the elastic force of the first elastic gasket 603 and the second elastic gasket 606, the circuit board 5 can be stably installed and fixed in the signal converter body 1, thereby improving its installation stability and facilitating its disassembly for later maintenance and replacement, thereby improving the practicality of the device.

[0033] In summary: through the provided connecting mechanism 6, the cover plate 4 can be conveniently installed on the upper part of the signal converter body 1, and it is also convenient to disassemble it. Not only can the circuit board 5 be stably installed and limited inside it, but it can also be conveniently maintained and replaced, thereby improving the practicality of the device; through the installation of the signal converter body 1 and the cover plate 4 through the connecting mechanism 6, the integrity of the device is improved, and the overall device is convenient for carrying and use, thereby improving the convenience of using the device.
