AI Technical Summary
The guqin has a low volume, and traditional pickups are difficult to amplify effectively during outdoor performances, and are prone to feedback. Existing technology cannot effectively solve this problem.
It employs a closed miniature capacitor pickup head, combined with a conductive silver paint layer to shield electromagnetic interference, and uses a sandalwood shell and an extremely fine shielding wire. It achieves sound pickup by picking up the vibration of the guqin body, avoiding environmental noise interference.
It achieves interference-free amplification, maintains the original tone of the guqin, avoids feedback, is easy and quick to install, and improves the signal-to-noise ratio.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of musical instrument technology, specifically relating to a pickup device for the guqin (a seven-stringed zither). Background Technology
[0002] The guqin (a seven-stringed zither) has become increasingly popular in China in recent years, leading to a surge in guqin performances. However, due to the guqin's thick soundboard and small resonating cavity, its volume is relatively low, making sound pickup a persistent challenge, especially for outdoor performances where traditional pickups are largely ineffective. Insufficient gain fails to amplify the sound, while increasing gain causes feedback. During a guqin performance at the Vienna Golden Hall, the recording engineer specially constructed a glass enclosure for the instrument to concentrate the sound and isolate external interference, ensuring the concert's success. Therefore, there is a pressing need for a pickup that can achieve interference-free amplification without feedback. Utility Model Content
[0003] This invention provides a pickup specifically designed for the guqin (a seven-stringed zither) to address the aforementioned problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A pickup specifically designed for the guqin (a seven-stringed zither) includes a housing in which a miniature condenser pickup head is embedded. A through hole is provided on one side of the housing for the lead wire of the miniature condenser pickup head to pass through. An end cap is provided at the upper end of the housing for completely sealing the housing.
[0006] Furthermore, a conductive silver paint layer is provided on the inner wall of the outer casing and connected to the ground wire of the miniature capacitor pickup head to shield electromagnetic interference.
[0007] Furthermore, the outer shell and end cap are made of sandalwood.
[0008] Furthermore, the leads of the miniature capacitor pickup head are made of extremely fine shielded wire.
[0009] Compared with the prior art, the present invention has the following advantages:
[0010] 1. The microphone head is enclosed inside, isolated from the outside air, blocking the interference of environmental noise, thereby effectively improving the signal-to-noise ratio and eliminating the occurrence of feedback in the loudspeaker system.
[0011] 2. The pickup head picks up sound by capturing the vibrations of the guqin's body, preserving the guqin's original timbre and filtering out environmental noise interference, resulting in a more realistic sound.
[0012] 3. The pickup head is attached to the body of the guqin with soft adhesive, making it easy and quick to install and use. Attached Figure Description

[0014] Figure 2 An exploded view of a pickup specifically designed for the guqin; Detailed Implementation
[0015] To further illustrate the technical solution of this utility model, the following embodiments will be used to further explain this utility model.
[0016] like Figure 1 and Figure 2 As shown, this embodiment is a pickup specifically for the guqin. The pickup includes a housing 1, in which a miniature condenser pickup head 2 is embedded. A through hole 3 is provided on one side of the housing 1 for the lead wire of the miniature condenser pickup head 2 to pass through. An end cap 4 is provided at the upper end of the housing 1 for completely sealing the housing 1. After grinding and polishing, the finished product is formed.
[0017] A conductive silver paint layer is provided on the inner wall of the outer casing 1 and is connected to the ground terminal of the miniature capacitor pickup head 2 to shield electromagnetic interference.
[0018] The outer shell 1 and the end cap 4 are made of sandalwood. The outer shell 1 is made of sandalwood cylindrical material with a diameter of 15mm and a height of about 15mm. A hole with a diameter of 10mm is drilled in the center of one end. The miniature capacitor pickup head 2 is embedded in the hole and sealed with glue.
[0019] The lead wire of the miniature condenser pickup head 2 is made of ultra-fine shielded wire with a diameter of 1mm. The miniature microphone amplifier circuit board is enclosed in the XLR connector and connected to the microphone lead wire through a 3.5 interface, so that it can be easily connected to professional amplification equipment to achieve good amplification of guqin performance.
[0020] When in use, the pickup is adhered to the body of the guqin with a suitable amount of adhesive putty for easy access. It directly picks up the vibrations of the guqin body and converts them into analog electrical signals, which are then transmitted to the amplification equipment. Because the pickup is completely enclosed, that is, the miniature condenser pickup head 2 is enclosed inside the outer shell 1, ambient noise is isolated and cannot be picked up. The vibrations of the guqin body are transmitted to the miniature condenser pickup head 2 through the outer shell 1 via direct contact with the pickup, achieving interference-free amplification of the guqin and completely avoiding the feedback of conventional microphones.
[0021] The foregoing has shown and described the main features and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
