Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Traditional African drums, limited by materials and manufacturing processes, are mostly made from hollowed-out pieces of wood, resulting in a hard drumhead and thick drum walls. This not only causes hand injuries during playing but is also inconvenient to carry. While modern African drums on the market have improved drumhead materials, they are still relatively hard. Electronic hand drums that can produce the sound of African drums have also appeared; however, their functions are limited to adjusting timbre and loudness, and improving sound quality, failing to meet the increasingly diverse performance requirements.

[0020] Please refer to Figures 1-4This utility model proposes an electronic African drum, including a drum body 1, an audio output device 2, a control device 3, and a support device 4. The drum body 1 includes a drumhead and a main cavity 12; the audio output device 2 and the control device 3 are disposed in the main cavity 12 and are electrically connected for transmitting sound.

[0021] In this embodiment, the electronic African drum includes a drum body 1, an audio output device 2, a control device 3, and a support device 4. The drum body includes a drumhead and a main cavity 12, with the drumhead positioned on and fixedly connected to the main cavity 12. The drumhead includes a foamed striking surface 11, a vibrating plate 13, a cushioning sponge 14, and a trigger bracket 15; the control device 3 is located within the main cavity 12.

[0022] Furthermore, the upper surface of the foamed striking surface 11 includes a first side striking area 6, a second side striking area 7, and a drum center area 8. The first side striking area 6 and the second side striking area 7 are respectively located on the outer side of the drum center area 8, and each area is distinguished by silkscreen printing on the foamed striking surface. The control device 3 includes a sensing element, a main control PCB control board 33, and a control panel. The sensing element and the control panel are electrically connected to the main control PCB control board 33. The sensing element is a signal conversion module in the control device 3, used to convert physical signals on the drum surface into electrical signals; the main control PCB control board is a signal processing module in the control device 3, capable of processing various electrical signals and transmitting them to the audio output device 2 for playback, realizing the various functions of the electronic African drum.

[0023] More specifically, the sensing elements include a buzzer 31 and an FPC membrane switch 32. The buzzer 31 is a highly sensitive element capable of detecting minute pressure changes on the striking surface. Located between the vibrating iron plate 13 and the cushioning sponge 14, the buzzer 31 converts the physical signals generated in the drum area 8 into electrical signals and transmits these signals to the main control PCB board 33. The FPC membrane switch 32 is an ultra-thin, flexible, and customizable tactile switch located between the trigger bracket 15 and the upper edge of the main cavity 12. It has a resistance value that continuously changes with contact pressure and position, used to detect the position and force of the user striking the edge area, transmitting the electrical signal through resistance changes to the main control PCB board 33. The main control PCB board 33 is located inside the main cavity 12 and fixed to the side near the control panel. It is electrically connected to the sensing elements, control panel, and audio output device 2, processing the various electrical signals generated by the sensing elements and control panel before transmitting them to the audio output device 2 for playback. Different timbres and loudnesses can be played depending on the different electrical signals from the sensing elements.

[0025] In practice: the foamed drumhead is integrally molded from ETPU (Expanded Thermoplastic Polyurethane) material through a mold after being melted. ETPU is a porous elastomer material formed by expanding thermoplastic polyurethane particles through physical or chemical foaming processes, combining the processability of plastics with the high elasticity of rubber. This material, used for the drumhead of an electronic African drum, possesses excellent properties of being lightweight, highly elastic, shock-absorbing, and durable. It solves the problem of hand injuries caused by the excessive hardness of traditional African drumheads.

[0026] Please refer to Figure 1 In one embodiment, the drumhead is composed of a foamed striking surface 11, a vibrating iron plate 13, a cushioning sponge 14, and a trigger bracket 15.

[0027] In practice, the foamed striking surface 11 and the vibrating iron plate 13 are bonded together with double-sided adhesive. The vibrating iron plate 13 effectively reduces signal crosstalk, accurately and efficiently transmits vibration signals, enhances signal accuracy and sensitivity, and provides stable support for the foamed striking surface 11, better simulating the feel of a real African drum. A cushioning sponge 14 is placed between the vibrating iron plate 13 and the trigger bracket 15 to absorb energy and filter vibration waves. This not only reduces the deformation amplitude of the FPC membrane switch 32 and extends the lifespan of the electronic African drum, but also filters environmental vibrations, preventing accidental activation. The cushioning sponge 14 has double-sided adhesive, one side adhering to the vibrating iron plate 13 and the other side connected to the trigger bracket 15. It filters out other vibration signals, transmitting the vibration signal from the edge striking area to the trigger bracket 15, where the signal is amplified and the FPC membrane switch 32 is triggered. The trigger bracket 15 is also fixedly connected to the drumhead with studs.

[0028] Please refer to Figure 3 In one embodiment, the drum body 1 includes a drum surface and a main cavity 12, with the upper edge of the main cavity 12 being fastened to the outer edge of the drum surface.

Two sets of integrally formed honeycomb array through holes are provided on the main cavity 12 at the positions corresponding to the fixed speaker assemblies 21, used to transmit the sound emitted by the speaker assemblies 21, while effectively preventing damage to the device from dust, foreign objects, or accidental contact, thus extending the device's service life. The audio output device 2 is electrically connected to the main control PCB control board 33, and the volume, timbre, and sound quality of the speaker assemblies 21 can be adjusted via the control panel. This design is more suitable for use in various occasions and solves the problem of traditional African drums having limited functionality and failing to meet diverse performance needs.
