Description

Technical Field

[0001] This utility model relates to the field of handpan technology, and in particular to a C·W handpan. Background Technology

[0002] The handpan is a lightweight and portable musical instrument, beloved by many for its unique timbre and tactile feel. When played, the handpan produces crisp, layered notes through the touch of the fingers and palm, with a warm and penetrating tone. Its wide range allows for the expression of a variety of emotions through different playing techniques, showcasing its unique charm in both simple melodies and complex rhythms. The handpan is frequently used in solo performances, meditation, and music therapy, bringing a sense of tranquility and harmony to the environment.

[0003] Traditional handpans often have a recessed pitch design, requiring precise control of striking force and angle to trigger a stable pitch. Furthermore, the pitch position depends on manual polishing and calibration, which can easily lead to pitch deviations for beginners due to improper operation, making the learning curve quite steep. The fixed center note design is also simple, making it impossible to achieve tonal variations through simple operation, thus limiting the expressive power of the performance.

[0004] Furthermore, existing handpans generally use complex key arrangements such as 9-tone D minor, and the distribution of pitches has no clear pattern. Users without musical background find it difficult to quickly establish the correspondence between pitch and melody, resulting in poor adaptability to popular music. In addition, most handpans only have basic striking functions and do not integrate electronic auxiliary components, which cannot meet the needs of modern performance scenarios such as accompaniment synchronization and sound amplification. Therefore, a C·W ding-tone handpan is proposed to improve the existing technology. Utility Model Content

[0020] As a further description of the above technical solution:

[0021] The control button includes a power button and a microphone switch. The control button has a diameter of 22mm and is rotatably connected to the top edge of the built-in cavity.

[0022] As a further description of the above technical solution:

[0023] The lithium battery has a capacity of 3000mAh, supports DC charging, and has a battery life of three hours.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, the raised tone zone allows beginners to quickly locate the tone position without needing to precisely control the force and angle to trigger a clear sound. Combined with the optimized arrangement of eight tones, it reduces the difficulty of memorizing tone positions, significantly shortens the learning cycle, and allows users of different ages to easily get started. The central opening and built-in cavity support friction sound generation and filling material sound effect simulation, enriching the tonal layers and enhancing the creativity and fun of playing.

[0026] 2. In this utility model, the accompaniment playback and sound amplification functions are realized through Bluetooth module, microphone and amplification unit, which is suitable for stage performance, personal practice and other scenarios. The standardized stamping process replaces the traditional handmade production, breaks the limitation of high price, and promotes the popularization of handpan from professional niche instrument to the general public, taking into account both professionalism and affordability.
