Description

TECHNICAL FIELD

[0001] The utility model relates to electric piano structure especially relates to a split assembly type electric piano structure. BACKGROUND

[0002] In the current music product market, desktop electric pianos become the favorite of many music lovers, especially limited space for family users, student groups and music creators, with their small and portable, non-space characteristics. This type of electric piano is usually placed on a desk, dining table and other flat surfaces, providing users with the convenience of playing music anytime, anywhere. However, the existing desktop electric pianos have many pain points in design and production mode, which limits the development of the industry and the improvement of user experience.

[0003] Production limitations of tightly binding keyboard modules and housings: Currently, the production mode of desktop electric pianos generally adopts an integrated design of tightly combining keyboard modules and housings. This means that the keyboard module of each brand or model of electric piano is customized and produced according to the specific size, shape and internal structure of the housing. For the manufacturer, this greatly increases the production and research and development costs. Whenever a new appearance design or functional upgrade is introduced, not only does the housing need to be redesigned, but also the relevant parameters of the keyboard module need to be adjusted simultaneously, resulting in a longer research and development cycle and slower new product launch speed. Moreover, due to the high binding of keyboard modules and housings, once a certain model of electric piano does not respond well in the market, the accumulated keyboard modules are difficult to reuse, causing resource waste and cost increase.

[0004] Market confusion caused by lack of standardized keyboard modules: There is a lack of unified standard desktop electric piano keyboard modules on the market, and each manufacturer does its own thing, with keyboard modules differing in size, specifications, key feel, circuit interface, tone configuration, etc. This makes it difficult for manufacturers to choose a suitable product when purchasing keyboard modules, as the selection range is limited. At the same time, this lack of uniformity also causes confusion for consumers, as different brands of desktop electric pianos lack coherence in user experience. When changing brands or models, users need to adapt to new keyboard feel and operation methods, which is not conducive to the healthy development of the electric piano market.

[0005] User personalization and diverse needs are difficult to meet: consumers' demand for desktop electric pianos is increasingly diverse, not only pursuing perfect function, but also focusing on the appearance and personal aesthetics, and the fit of the use scene. However, under the existing design mode of desktop electric pianos, users are difficult to replace the shell according to their own preferences. For the young user group pursuing personalization, they hope that the electric piano can integrate unique artistic elements, popular cultural elements, or match the home decoration style; for commercial users, such as cafes, restaurants and other places, they also hope to change the electric piano shell to make it a decorative highlight in the store. However, the design of the existing product cannot meet these diverse needs, limiting the application and promotion of desktop electric pianos in more scenarios.

[0006] Therefore, it is an urgent problem for those skilled in the art to develop a split assembly type electric piano structure. Utility model content

[0007] The utility model provides a split assembly type electric piano structure to solve the above-mentioned shortage.

[0008] The utility model discloses the above-mentioned purpose is realized through the following technical scheme: a split assembly type electric piano structure, including modularized key bed and replaceable shell, the modularized key bed has the standardized size and interface, and can be adapted to the shell of different designs. The shell is provided with mounting slot or clamping position that is adapted to the modularized key bed, which facilitates the stable assembly of the modularized key bed.

[0009] Modularized key bed: the modularized key bed includes key assembly, circuit board and support, the circuit board integrates plucking simulation device and control circuit, and the whole forms an independent standardized module. The control circuit is equipped with a standardized data transmission interface, such as a USB interface, which can be connected to external devices such as computers and mobile phones to realize sound expansion, music score transmission and other functions; at the same time, a standardized power supply interface is arranged, which is convenient for connecting external power supply or charging equipment.

[0010] Shell design: the shell is divided into face shell and bottom shell, and the face shell and the bottom shell are combined together through detachable connection mode. The detachable connection mode includes but is not limited to buckle connection, screw connection or magnetic attraction connection. When the buckle connection is used, the edge of the face shell is provided with a clamping hook, and the bottom shell is provided with a clamping groove at the corresponding position, or vice versa; the screw connection is arranged with corresponding screw holes on the face shell and the bottom shell; the magnetic attraction connection is that the corresponding positions of the face shell and the bottom shell are embedded with matched magnets. In addition, the shell can be made of various materials, such as wood, plastic, metal and the like, to meet the diverse needs of different users for the appearance texture.

[0011] Damping design: in order to improve the playing experience and reduce the vibration transmission during playing, damping buffer components such as rubber pad and silica gel pad are arranged between the mounting slot or clamping position of the modularized key bed and the shell.

[0012] Operation opening: the face shell is provided with operation openings corresponding to the positions of the modular keybed piano keys, and the edges of the operation openings are smoothly processed to prevent the fingers of the user from being scratched during playing.

[0013] Compared with the prior art, the utility model has the advantages of:

[0014] 1. Reduce production and research and development cost: the standardized design of the modular keybed makes the production manufacturer not need to redesign the keybed for each new shell, and only needs to produce the modular keybed according to the standard, so that the production and research and development cost is greatly reduced, the development of different appearance electric pian and its rapid assembly are facilitated, the new product release cycle is shortened, and the market demand can be quickly responded.

[0015] 2. Meet individualized demand: the consumer can freely select the shell of different materials and styles according to personal preference, home environment or use scene, and assemble the shell with the modular keybed, so that the individualized customization of the electric piano is realized, and the use value and user satisfaction of the product are improved.

[0016] 3. Facilitate maintenance and maintenance: when the electric piano appears failure, if the keybed is damaged, the modular keybed can be directly replaced, and if the shell is damaged, the shell can be replaced alone, so that the electric piano does not need to be replaced as a whole, the maintenance difficulty and cost are reduced, the service life of the electric piano is prolonged, and resource waste is reduced.
