Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0034] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] Reference Figure 1-5As shown, an electronic African drum comprises a drum plate 7, the drum plate 7 comprises an upper opening and a lower opening, the upper opening is covered with a layer of drum skin 1, a partition plate 4 is arranged above the lower opening, the drum skin 1 and the partition plate 4 form a drum cavity with the drum plate 7; a struck component 2, the struck component 2 is arranged in the drum cavity, the upper surface of which is in contact with the drum skin 1, the lower surface of the struck component 2 is provided with a sensor component 3, the sensor component 3 is composed of a plurality of piezoelectric ceramic buzzer sheets, the piezoelectric ceramic buzzer sheets are an existing mature technology, and can convert the striking signal into an electrical signal; a mainboard 11 (the mainboard 11 is a special computer, which can receive and process the electrical signal of the sensor component 3, and then transmit the electrical signal to the speaker 9, and those skilled in the art can fully know its working principle, and can flexibly modify and adjust its internal software program according to actual needs, so it will not be repeated in the following embodiments), the mainboard 11 is arranged in the drum cavity, The sensor component 3 is electrically connected to the mainboard 11. The mainboard 11 is provided with a Bluetooth module, an audio Bluetooth and a Midi Bluetooth (both are prior arts). The utility model can also be used as an ordinary Bluetooth speaker. The mainboard 11 has built-in software that restores drum sounds of different pitches and timbres through a speaker. It is also a Bluetooth speaker with built-in battery power supply and a compact and portable design. This product connects to the APP via a data cable or Bluetooth, so that everyone can easily learn to play African drums. Each time practicing, the mobile phone or tablet APP guides drum teaching or on-site scoring and other functions, and the gathering can be used for entertainment projects to compete with each other. The speaker 8 is connected to the bottom of the drum plate 7. A speaker 9 is provided in the speaker 8, and the speaker 9 is electrically connected to the mainboard 11. After the struck component 2 is struck, the sensor component 3 converts the striking signal into an electrical signal and transmits it to the mainboard 11. The mainboard 11 processes the electrical signal and then sends an electrical signal to the speaker 9 for sound.

[0036] The knocked component 2 includes four fan-shaped plates 202 and a circular plate 201, all of which are made of metal iron. A piezoelectric ceramic buzzer is provided at the center below the circular plate 201, and a piezoelectric ceramic buzzer is provided at each end below each fan-shaped plate 202. When the knocked component 2 is knocked, the knocking signal is received more accurately. The four fan-shaped plates 202 are arranged around the circular plate 201, and there is a gap between each plate. This arrangement can divide different knocking areas. When different areas are knocked, the speaker 9 can emit the same / different timbre (the specific area combination can be set according to actual conditions).

[0037] A diaphragm 6 is also provided on the drum plate 7. The diaphragm 6 is provided below the partition 4 and covers the lower opening. A sound cavity 17 is formed between the partition 4 and the diaphragm 6. The sound cavity 17 is not communicated with the drum cavity. A connected inverted hole 18 is provided on the drum plate 7 and the sound box 8. The inverted hole 18 is communicated with the sound cavity 17, so that the sound cavity 17 is communicated with the outside. When the speaker 9 makes a sound, it vibrates, and the vibration is transmitted to the diaphragm 6. The diaphragm 6 amplifies the vibration, emits sound and transmits it through the inverted hole 18.

[0038] It should be noted that the inverted hole 18 can enhance the sound waves of a specific frequency, especially the low frequency part, by resonating with the air inside the sound cavity 17. This resonance effect can expand the low frequency response range and make the bass deeper and richer. The addition of the diaphragm 6 can further adjust the low frequency response. By changing the stiffness and mass of the diaphragm 6, the low frequency characteristics of the speaker 8 can be fine-tuned to meet different sound quality requirements.

[0039] The circular plate 201 is fixed to the drum disc 7 by screws, and a number of O-rings 12 are placed between the two. The short arc side of the fan-shaped plate 202 is connected to the drum disc 7 by a double-sided adhesive pad 13, and the long arc side is connected to the drum disc 7 by screws, and a number of O-rings 12 are placed between the two. When it is necessary to remove and repair, it is only necessary to pry open the corners of the drum skin 1 and remove the screws on the long arc side of the fan-shaped plate 202 to open most of the area and contact the main board 11, thereby reducing damage to the overall structure.

[0040] A through hole 801 is also provided at the bottom of the drum plate 7. The through hole 801 connects the drum cavity with the inner cavity of the sound box 8 and is used for connecting the main board 11 with the speaker 9. The through hole 801 is provided below the drum cavity and is not connected with the sound cavity 17.

[0041] A speaker net 10 is provided at the bottom of the sound box 8 to protect the speaker 9 .

[0042] The struck component 2 is attached to the drum skin 1 by means of double-sided adhesive.

[0043] The device also includes a battery 5, which is disposed in the drum cavity and is electrically connected to the main board 11. When a power source is built in, the device can be more convenient to carry outside.

[0044] The drum pad 7 is also provided with buttons 16 (including but not limited to power switch, volume adjustment, tone switching), indicator light 14 and charging port 15, all of which are connected to the mainboard 11 (the control of the buttons 16 and the display of the indicator light 14 are fully known to those skilled in the art and can be flexibly modified and adjusted according to actual needs, so they will not be repeated here), and the function of the charging port 15 is not limited to the charging function, but can also perform data transmission.

[0045] Among them, the tone switching defaults to African drum tone, and other tones can be switched by pressing button 16, with a total of seven tones available for switching; the indicator light status is that the red light flashes quickly when the battery is low; the red light flashes slowly during charging; the red light is on when the battery is full (charging stops); the red light is on when Bluetooth is not connected; the purple light is on when Bluetooth is connected.

[0046] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
