Description

Technical Field

[0001] The present invention relates to the technical field of the output interface of an electric guitar, and specifically to the active / passive pickup mode switching output interface of an electric guitar.

Background Art

[0002] The pickups of an electric guitar are mainly divided into two types: passive pickups and active pickups. The two are significantly different in terms of tone characteristics and operating principles. Passive pickups do not require external power supply. When the strings cross the magnetic field, an audio signal is generated. The tone is warm and rich, and the dynamic response is natural. However, the output level is low, the anti-interference ability is weak, and noise floor or current noise is likely to occur during high-gain playing. Active pickups have a built-in amplifier circuit and require power supply from an external power source. They have a high output level, low noise, and a clear and crisp tone. However, they lack the original dynamics and warm texture of passive pickups, and the range of tone expression is relatively narrow.

[0003] In the conventional method, in order to achieve active / passive switching or the installation of an active circuit in an electric guitar, usually, a circuit board, a battery, a potentiometer, a switch, etc. are distributed and arranged in the cavity inside the guitar, and soldering connections need to be made through a plurality of wires. Therefore, relatively high soldering skills of electronic components and guitar circuit modification skills are required for workers, and the work takes a long time.

[0004] Therefore, in order to solve the above problems, an active / passive pickup mode switching output interface for an electric guitar is provided.

Summary of the Invention

[0005] In view of the limitations of the prior art, this invention provides an active / passive pickup mode switching output interface for electric guitars. This solves the problem that, in conventional methods, in order to achieve active / passive switching or the installation of an active circuit in an electric guitar, it is usually necessary to distribute circuit boards, batteries, potentiometers, switches, etc., within the cavity inside the guitar and solder connections via multiple wires. This requires workers to have relatively high skills in soldering electronic components and modifying guitar circuits, and the work is time-consuming.

[0006] To achieve the above objective, the present invention provides the following technical means: an integrated mounting panel is included, the front of which a switching mechanism is attached, and the front of which mounting holes are formed. The switching mechanism includes a PCB circuit board, an audio output jack, an active / passive mode selector switch, a button battery, a boost circuit, an active signal processing circuit, and a gain adjustment potentiometer.

[0011] Preferably, the active / passive mode selector switch controls the input terminal of the audio output jack to switch between the passive pickup signal path and the active pickup signal path via the active / passive isolation and switching control circuit.

[0012] Preferably, when switched to the active pickup signal path, the button battery supplies power to the active signal processing circuit, and the gain adjustment potentiometer and the active signal processing circuit constitute a gain adjustment network used to adjust the output signal amplitude in the active mode.

[0013] Compared to conventional technology, the active / passive pickup mode switching output interface for electric guitars according to the present invention has the following beneficial effects. (1) The PCB circuit board, audio output jack, active / passive mode selector switch, button battery, boost circuit, active signal processing circuit, and gain adjustment potentiometer are all integrated onto the same structure using an integrated mounting panel, forming an assembly that can be mounted as a single unit, eliminating the need for additional wiring or drilling inside the guitar.

[0017] The technical means in the embodiments of the present invention will be described clearly and completely below with reference to the drawings of the embodiments. Clearly, the embodiments described are only some, and not all, embodiments of the present invention. All other embodiments that a person skilled in the art could obtain without creative effort based on the embodiments of the present invention are all within the scope of the protection of the present invention.

[0018] Examples As shown in Figures 1 to 4, the active / passive pickup mode switching output interface for the electric guitar in this embodiment includes an integrated mounting panel 1, a switching mechanism 2 is mounted on the front of the integrated mounting panel 1, and mounting holes are formed on the front of the integrated mounting panel 1. The switching mechanism 2 includes a PCB circuit board 21, an audio output jack 22, an active / passive mode selector switch 23, a button battery 24, a gain adjustment potentiometer 25, an active signal processing circuit 27, and a boost circuit 26. The PCB circuit board 21 is fixedly connected to the front of the integrated mounting panel 1, the audio output jack 22 is fixedly connected to the rear of the integrated mounting panel 1, the active / passive mode selector switch 23 is fixedly connected to the rear of the integrated mounting panel 1, the button battery 24 is fixedly connected to the surface of the PCB circuit board 21, the boost circuit 26 is fixedly connected to the surface of the PCB circuit board 21, the gain adjustment potentiometer 25 is fixedly connected to the surface of the PCB circuit board 21, and the active signal processing circuit 27 is fixedly connected to the surface of the PCB circuit board 21. The integrated mounting panel 1 integrates the PCB circuit board 21, audio output jack 22, active / passive mode selector switch 23, button battery 24, gain adjustment potentiometer 25, active signal processing circuit 27, and boost circuit 26 onto the same structure, realizing a compact and modular active / passive switchable output interface that can directly replace the conventional output interface of an electric guitar. The integrated mounting panel 1 serves as the structural base, with the PCB circuit board 21, button battery 24, gain adjustment potentiometer 25, active signal processing circuit 27, and boost circuit 26 fixed to its front, and the audio output jack 22 and active / passive mode selector switch 23 fixed to its back, forming an assembly in which all components can be mounted as a single unit via the panel.

[0019] The audio output jack 22 is fixed through the integrated mounting panel 1, and the extended end of the audio output jack 22 is electrically connected to the PCB circuit board 21. This enables the audio output jack 22 to perform a dual function of mechanical fixing and electrical signal transmission, ensuring a reliable connection between the audio output jack 22 and the PCB circuit board 21. The audio output jack 22 is fixed by passing through the integrated mounting panel 1, and its extended end is directly electrically connected to the PCB circuit board 21, allowing the signal from the pickup or the signal after active processing to be output to an external amplifier via the jack.

[0020] The gain adjustment potentiometer 25 is electrically connected to the PCB circuit board 21, the button battery 24 is electrically connected to the PCB circuit board 21, the active signal processing circuit 27 is electrically connected to the PCB circuit board 21, and the boost circuit 26 is electrically connected to the PCB circuit board 21, providing a physical base for signal adjustment, power supply, and filtering in active mode. Of these, the gain adjustment potentiometer 25 and the active signal processing circuit 27 are used to adjust the gain, and the button battery 24 and the boost circuit 26 provide power for active mode.

[0021] The active / passive isolation and switching control circuit is electrically connected to the active / passive mode selector switch 23, the active signal processing circuit 27 is electrically connected to the gain adjustment potentiometer 25, the active / passive mode selector switch 23 is electrically connected to the active / passive isolation and switching control circuit to transmit switching commands, and the boost circuit 26 is electrically connected to the gain adjustment potentiometer 25 and the active signal processing circuit 27 to participate in gain adjustment.

[0022] The active / passive mode switching switch 23 controls, via an active / passive separation and switching control circuit, the input terminal of the audio output jack 22 to switch between a passive pickup signal path and an active pickup signal path. When the active / passive mode switching switch 23 sends a switching command, the active / passive separation and switching control circuit controls, based on this, the input terminal of the audio output jack 22 to switch between a path that directly passes the passive pickup signal path and an active pickup signal path via the active signal processing circuit.

[0023] When switched to the active pickup signal path, the button battery 24 supplies power to the active signal processing circuit 26, and the gain adjustment potentiometer 25 and the active signal processing circuit 27 constitute a gain adjustment network, and by changing the feedback depth or filtering characteristics, the output signal amplitude in the active mode is adjusted.

[0024] The operating principle of the above embodiment is as follows. After the user fixes the integrated mounting panel 1 at the original output interface position of the electric guitar, a mode selection command is output by switching the active / passive mode switch 23. This command is identified by the active / passive separation and switching control circuit on the PCB circuit board 21. Based on this, the input end of the audio output jack 22 is controlled to be switched between the passive pickup signal path and the active pickup signal path. When switched to the passive mode, the pickup signal is directly output to an external amplifier via the audio output jack 22. At this time, the button battery 24, the gain adjustment potentiometer 25, and the active signal processing circuit 27 are not involved in the operation, and an original sound output that does not require power supply is realized. When switched to the active mode, the button battery 24 supplies power to the active signal processing circuit on the PCB circuit board 21. The pickup signal is first input to the active signal processing circuit, and then input to the gain adjustment network formed by the gain adjustment potentiometer 25 and the active signal processing circuit 27 together. The user can change the feedback depth or filtering characteristics of the gain adjustment network by rotating the gain adjustment potentiometer 25, thereby adjusting the output signal amplitude. Finally, the processed signal is output to an external amplifier via the audio output jack 22, and the one-touch switching between the active / passive modes and the gain adjustment function in the active mode are realized.

[0025] The mounting method, connection method, or installation method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as the beneficial effects can be achieved. Therefore, in this embodiment, detailed descriptions of its specific structural configuration and operating principle are omitted.

[0026] Although embodiments of the present invention have been illustrated and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is limited by the attached utility model claims and equivalents.
