Description
Technical Field
[0001] This utility model relates to the field of kahon drum technology, specifically a kahon drum and its sounding device. Background Technology
[0002] Modern cajon making techniques have continued to evolve. In addition to the traditional all-wood structure, new materials and designs have been adopted. Cajons, made of multiple layers of solid wood boards, are simple to use and are excellent tools for rhythm training. Many music training institutions use them for rhythm teaching, which can cultivate beginners' sense of rhythm and musical interest.
[0003] Existing cajons generally have a relatively simple tone, lacking variety in different performance scenarios. Although the tone can be adjusted by the striking point and force, it still falls short of meeting the needs of diverse musical styles. While adjusting the tension of the sound strings can change the tone, this is inconvenient during performance because the adjustment device is usually inside the drum, requiring opening the drum box or accessing it through a special small hole, which interrupts the performance. To address these shortcomings, this invention provides a cajon and its sounding string device to solve the aforementioned problems. Utility Model Content
