Description

Technical Field

[0001] This utility model belongs to the field of pickup technology, and in particular relates to a pickup for tuning musical instruments. Background Technology

[0002] Currently, the pickup structure, as a crucial core component of musical instruments, is an electroacoustic instrument that receives sound oscillations and amplifies them. The pickup captures or senses the mechanical vibrations produced by the instrument, converts these vibrations into electrical signals, and then uses an instrument amplifier to amplify these signals to produce musical sound through a loudspeaker within the speaker housing. For example, most electric guitars on the market have an integrated design, with the pickup fixed to the body. A typical electric guitar has a maximum of three pickups, which limits the guitar's tonal range. To obtain a wider range of tones, additional pickups must be added or replaced, increasing the cost for the user. Utility Model Content

[0018] See Figure 1 and Figure 2 This utility model provides a pickup for tuning musical instruments, including an audio signal input module 10, an audio switching module 20, a signal processing module 30, and a signal output module 40. The audio signal input module 10 and the signal processing module 30 are both connected to the audio switching module 20, and the audio switching module 20 and the signal output module 40 are both connected to the signal processing module 30. The audio signal input module 10 includes a first microphone 11 and a second microphone 12. The audio switching module 20 includes a third microphone 21 and a toggle switch 22 connected to the signal processing module 30. The first microphone 11, the second microphone 12, and the third microphone 21 are all connected to the toggle switch 22. The first microphone 11 and the second microphone 12 output an initial audio signal to the toggle switch 22. The toggle switch 22 receives the initial audio signal and switches the third microphone 21 to output a target audio signal to the signal processing module 30. The signal processing module 30 performs tuning processing on the target audio signal and outputs it through the signal output module 40.

[0019] In this embodiment, the signal processing module 30 includes a volume potentiometer 31 and a timbre potentiometer 32. The third microphone 21, the toggle switch 22, the timbre potentiometer 32, and the signal output module 40 are all connected to the volume potentiometer 31. The volume potentiometer 31 is used to adjust the volume of the target audio signal, and the timbre potentiometer 32 is used to adjust the timbre of the target audio signal. The signal output module 40 is a JACK interface, which is used to output the target audio signal processed by the signal processing module 30 to an audio device. The signal processing module 30 also includes a power supply unit 50, and the third microphone 21, the volume potentiometer 31, the timbre potentiometer 32, and the toggle switch 22 are all connected to the power supply unit 50. The third microphone 21 is connected to a first wire 41, a second wire 42, a third wire 43, and a fourth wire 44. The first wire 41 is connected to the toggle switch 22, the fourth wire 44 is connected to the volume potentiometer 31, and the second wire 42 and the third wire 43 are connected to the power supply unit 50.

[0020] It should be noted that the volume potentiometer 31 is a B500K potentiometer, the tone potentiometer 32 is an A500K potentiometer, the first pickup 11 and the second pickup 12 are both single-coil pickups, and the third pickup 21 is a dual-coil pickup. The first pickup 11 and the second pickup 12 are connected to the toggle switch 22 via a single wire. The toggle switch 22 is a five-position parallel switching control switch. Typically, a pickup consists of a transducer (specifically a variable resistance sensor) composed of a coil wound with several turns of enameled copper wire and one or more permanent magnets (usually AlNiCo or ferrite). The magnets generate a magnetic field, which is focused by one or more pole pieces of the pickup. The permanent magnets in the pickup magnetize the guitar string above it, thereby generating a magnetic field around the string that matches the magnetic field of the pickup magnet. When the string is plucked, the surrounding magnetic field moves up and down with the string, and this moving magnetic field induces a current in the pickup coil. The power supply unit 50 can be a battery or a rechargeable battery. The pickup is connected to an amplifier via a plug cable, which amplifies the signal to a level of power sufficient to drive the amplifier (e.g., tens of volts). The pickup can also be connected to a recording device via a plug cable. The pickup is usually mounted on the body of the instrument, but can also be attached to the bridge, neck, and / or pickguard.

[0021] A single-coil pickup acts like a directional antenna and is well-suited for picking up power hum—annoying AC electromagnetic interference from power cables, transformers, fluorescent lamp ballasts, video monitors, or televisions—as well as music signals. Power hum consists of a nominal 50 or 60 Hz fundamental signal, depending on the local current frequency, and often includes some harmonic content. Power hum can be overcome by using a duocoil pickup. A duocoil pickup consists of two coils, each wound in opposite directions. The polarities of each pair of magnetic poles are also opposite. Because the ambient hum from electrical installations reaches the coils as common-mode noise, it induces an equal voltage in each coil, but with a 180-degree phase difference between the two voltages. They effectively cancel each other out, while the signal from the guitar strings is doubled.

[0022] As mentioned above, when connected in series, as is most common, the total inductance of the pickup increases, which lowers its resonant frequency and attenuates higher frequencies, resulting in a lower treble tone than either of the two components in a single-coil pickup would produce individually. Another wiring method is to place the coils in parallel with a step-down configuration, which has a more neutral effect on the resonant frequency and lowers the output while extending the high-frequency response. Side-by-side humbuckers sense a wider portion of each string than single-coil pickups. By picking up a larger portion of the vibrating string, higher-frequency harmonics in the pickup's signal are canceled out, resulting in a "fatter" tone. Humbuckers with a narrower single-coil profile are designed to replace single-coil pickups, having a narrower aperture similar to that of a single-coil pickup, which reduces harmonic cancellation and produces a brighter sound, more like a single-coil pickup.

[0023] Specifically, each pickup coil has two fundamental characteristics that affect the sound it produces when combined with other pickup coils. These characteristics are called phase and magnetic polarity. Phase is the direction in which current flows through the pickup, and polarity is the orientation of the magnetic field. With these two characteristics, there are only two choices. The phase can be "top in" or "top out," determined by the winding direction of the coil, or "counterclockwise" or "clockwise," indicating the rotation direction of the winding machine spindle. The magnetic polarity can be "south" or "north."

[0024] The characteristic of single-coil pickups is that, based on their phase and polarity, they can potentially eliminate hum when combined. The key to a strong, full tone without hum is to combine single-coil pickups with opposite phases (or "winds") and opposite polarities. If one pickup is north, coming in from the top, the other must be south, leaving from the top. Dual-coil pickups all work on this principle. The two coils are wound in opposite directions and have opposite polarities. When combined in series, it produces a thick, fleshy tone without hum. Of course, splitting a dual-coil pickup brings back the hum, but results in a brighter, cleaner sound with more high-frequency content. Combining the two coils in parallel maintains hum elimination and produces a brighter tone than in series, but less output and less brightness than in split mode.

[0025] Specifically, such as Figure 3 and Figure 4As shown, the third pickup 21 is a dual-coil pickup. The third pickup 21 is connected to a first wire 41, a second wire 42, a third wire 43, and a fourth wire 44, with corresponding colors of black, red, white, and green. The first wire 41 is connected to the toggle switch 22. Both the first pickup 11 and the second pickup 12 have two wires. The first pickup 11 and the second pickup 12 are connected to the toggle switch 22 via one of the wires and are close to the first wire 41; the other wire is grounded. The toggle switch 22 includes three control modes and a five-position pickup connection method. The three control modes are: front toggle single-position mode, middle toggle regular five-position mode, and rear toggle parallel mode. The upper and lower coils of the third pickup 21 are divided into north and south poles. The specific switching control process of the toggle switch 22 is as follows: When the toggle switch 22 is in the forward shift single-shift mode, the first pickup 11 is engaged in shift 1 (position 1), the first pickup 11 and the second pickup 12 are engaged in shift 2 (position 2), the second pickup 12 is engaged in shift 3 (position 3), the second pickup 12 and the north pole are engaged in shift 4 (position 4), and the north pole is engaged in shift 5 (position 5). When the toggle switch 22 is in the middle shift normal five-shift mode, the first pickup 11 is engaged in shift 1, and the first pickup 12 is engaged in shift 2. 11 and the second pickup 12 are connected. In the third gear, the second pickup 12 is connected. In the fourth gear, both the second pickup 12 and the third pickup 21 are connected. In the fifth gear, the third pickup 21 is connected. When the toggle switch 22 is in the rear gear parallel mode, in the first gear, the first pickup 11 and the south pole are connected. In the second gear, the first pickup 11, the second pickup 12 and the south pole are connected. In the third gear, the second pickup 12 and the south pole are connected. In the fourth gear, the second pickup 12 and the south pole are connected. In the fifth gear, the south pole is connected.

[0026] Specifically, the first pickup 11 and the second pickup 12 capture and amplify the string vibration signal through magnetic resonance to form the initial audio signal. The front and rear sections (north and south poles) of the bridge pickup (third pickup 21) can be directly switched via the toggle switch 22, allowing for individual operation (front or rear pickup) or parallel operation without the need for additional circuit boards. The signal is controlled by a B500K potentiometer to adjust volume and tone (VOLUMI volume control, TONE tone control), and finally outputs the audio signal (target audio signal) to the audio equipment via the JACK interface (6.35mm). In addition to the traditional five-way tone switching, a parallel option for the rear bridge pickup (south pole pickup) is added, enriching the possibilities for tone combinations. It should be understood that this is the first time a parallel mode for bridge pickups has been introduced into a traditional circuit, allowing for direct switching via physical toggle switches. Operation is simple and requires no complex circuit boards. It supports individual operation or parallel combination of the front and rear bridge pickups, expanding tonal range (such as bright, full, or mixed effects). The structure is simplified: through magnetic resonance signal amplification and toggle switch mechanical design, reliance on additional electronic components is reduced, resulting in a more compact and reliable circuit. The traditional five-position switching function is retained, while an independent parallel position is added, compatible with existing electric guitar modification needs. Magnetic resonance technology enhances signal sensitivity, and the B500K potentiometer precisely controls output dynamics, ensuring clear and stable sound quality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
