Description

Technical Field

[0001] The present application relates to the technical field of musical instrument devices, and specifically to drum-shaped interactive sound systems. Background Art

[0002] Traditional drums, such as leather drums, drum kits, and waist drums, are played by striking the drumhead. Drumming is typically performed in groups. When performed alone in open spaces, the sound is low, which can easily lead to a lack of ambiance. Practicing drums in residential buildings can also be excessively loud, potentially disturbing others.

[0003] In the prior art, there is a slap drum set disclosed in the patent document with patent application number 201420695282.7, please refer to Figure 1 By electronicizing the drum set and using a speaker 8 as a drum sound output device, the output sound volume can be controlled to solve the above problem. The slapping plate 3 is about the size of a palm and is installed on the side drum 2. During operation, when the drummer slaps the slapping plate 3, the vibration sensor 5 in the control device 4 will send the received information to the single-chip microcomputer 6. The single-chip microcomputer 6 then analyzes the received information and outputs the drum sound corresponding to the vibration frequency pre-introduced by the vibration sensor 5. Finally, the controller 7 prompts the speaker 8 to realize the drum sound.

[0004] It can be seen that this type of electronic drum does not produce drum sounds by hitting the drumhead, so it lacks the realism and immersion of hitting the drum, and the user experience is not good. Utility Model Content

[0026] Please refer to Figure 2 - Figure 4 This embodiment provides a drum-shaped interactive sound, including a drum body, a first speaker 1, a second speaker 2, an acceleration sensor 3, a power supply 4, a power amplifier 5, and a main controller 6. At least one drum head of the drum body is a passive radiator 7; the acceleration sensor 3 is connected to the passive radiator 7 and distributed in an array; the first speaker 1, the second speaker 2, the acceleration sensor 3, the power supply 4, and the power amplifier 5 are all electrically connected to the main controller 6; the first speaker 1 is a full-range speaker or a high-frequency speaker, and the second speaker 2 is a low-frequency speaker; the main controller 6 controls the first speaker 1 and the second speaker 2 to play corresponding drum audio according to the striking motion information of the passive radiator 7 collected by the acceleration sensor 3.

[0027] The passive radiator 7 itself is basin-shaped or disc-shaped, and is shaped like a flat drum surface structure, so that it can replace the traditional drum surface without requiring the user to change the habit of striking the drum. Moreover, the drum sound gain is adjustable, so there is no need to strike the drum surface with great effort in a manner in which the loudness is proportional to the striking force. The acceleration sensors 3 distributed in an array are used to collect the user's striking information and transmit the electrical signal to the main controller 6. The main controller 6 controls the first speaker 1 and the second speaker 2 to play the corresponding drum audio according to the audio signal processed by the power amplifier 5 based on the motion information of the passive radiator 7 received by the acceleration sensor 3. Thus, the drum-shaped interactive audio simulates the traditional physical drum, has high realism, and the drum sound is adjustable, which saves physical energy for the user and can also avoid environmental sound pollution.

[0028] Importantly, the sound produced by the actual vibration of the passive radiator 7 when struck is far less than that of a flat drumhead, and far less than the sound produced by tapping a drum plate in the prior art, thus preventing the actual sound from interfering with the drum sound emitted by the speaker. The acceleration sensor 3 is also more accurate in picking up and collecting striking signals than conventional vibration sensors. When struck, the passive radiator 7 has an actual amplitude, simulating the movement of the drumhead. Simultaneously, the vibration of the passive radiator 7 provides force and vibration feedback to the hand, providing a highly realistic experience.

[0029] Preferably, the surface of the passive radiator 7 is covered with a soft material such as rubber or silicone, that is, a flexible layer (not shown), so that the actual vibration sound of the source radiator 7 when hit is further optimized and reduced.

[0030] The specific working principle is as follows: due to the structural characteristics of the passive radiator 7, the drum body will vibrate up and down under the influence of internal air pressure. By utilizing this characteristic, an acceleration sensor 3 is placed under the passive radiator 7 to detect the amplitude of its displacement. In this way, when the speaker switches to the slapping mode, the passive radiator 7 is slapped by hand to cause it to vibrate and produce displacement. The acceleration sensor 3 receives the displacement data and transmits it to the main controller 6. The processing module of the main controller 6 uses the corresponding algorithm to perform calculations, calls the corresponding drum audio from the storage module, and then controls the power amplifier 5 to output the corresponding audio signals to the first speaker 1 and the second speaker 2. In this way, the signal conversion when the user slaps is completed.

[0031] In some embodiments, the center of the passive radiator 7 can be used as a reference. The user hits the passive radiator 7 at different areas and with different strengths, corresponding to the different areas and strengths of the actual drum being struck. The processing module of the main controller 6 uses the corresponding algorithm to perform calculations and calls the storage module to ensure that the corresponding drum audio is consistent with the actual sound of the drum being struck.

[0032] The connection circuits between the main controller 6 and the corresponding modules and the program algorithms built into the main controller 6 belong to the fields of circuits and software solutions, and are not the focus of the present invention, and will not be elaborated here.

[0033] The power supply 4 can be a battery or a power adapter for connecting to an external AC power source.

[0034] Please refer to Figure 3 The first speaker 1 and the second speaker 2 are both built into the inner cavity of the drum body, and the drum body is provided with a sound avoidance portion 14 corresponding to the first speaker 1 and the second speaker 2.

[0035] In some embodiments, the first speaker 1 has three full-range speakers or tweeters, which are evenly distributed, and the sound output ends are perpendicular to the center line connecting the upper and lower drum heads.

[0036] The second speaker 2 is a large-sized low-frequency speaker. When the number of the passive radiator 7 is one, the sound output end of the second speaker 2 is set away from the passive radiator 7. In this case, the three full-range speakers or high-frequency speakers and the low-frequency speaker are preferably arranged in an upper and lower layout, which is more reasonably positioned and fully utilizes the space.

[0037] Please refer to Figure 3The acceleration sensor 3, power supply 4, power amplifier 5 and main controller 6 are all built into the inner cavity of the drum body.

[0038] Please refer to Figure 3 and Figure 4 The passive radiator 7 includes a counterweight 710 located in the middle and a flexible edge 720 arranged around the counterweight 710.

[0039] The elastic flexible edge 720 has relatively good ductility and deformation effect, providing elasticity for vibration deformation.

[0040] Preferably, the main controller 6 is provided with a wireless communication module (not shown), and the main controller 6 controls the first speaker 1 and the second speaker 2 to play audio according to the audio signal received by the wireless communication module.

[0041] In some embodiments, the wireless communication module is a Bluetooth module.

[0042] When the drum-shaped interactive audio device is not used as a drum instrument, the first speaker 1 and the second speaker 2 serve as sound output devices of the audio device. When the device is used as an audio device, the passive radiator 7 in turn serves as an auxiliary device for the first speaker 1 and the second speaker 2, and can enhance the bass effect when playing low-frequency audio.

[0043] This drum-shaped interactive speaker serves two purposes, bringing a diverse experience to users.

[0044] Please refer to Figure 3 , the power supply 4 is a battery pack.

[0045] Please refer to Figure 2 and Figure 3 , including a drum frame 8 for setting up the drum body.

[0046] In some examples, the counterweight 710 is any one of an iron block, a plastic sheet, and a steel sheet, and the flexible edge 720 is made of rubber or silicone.

[0047] Please refer to Figure 3 The main controller 6 is provided with a wired audio input socket (not shown), a wired audio output socket (not shown), and a charging port (not shown); the drum body is provided with a avoidance port 9 corresponding to the wired audio input socket, wired audio output socket, and charging port.

[0048] The charging port is used to power and charge the battery pack.

[0049] Please refer to Figure 3The drum body includes a support frame 10 that encloses the first speaker 1, the second speaker 2, the acceleration sensor 3, the power supply 4, the power amplifier 5, and the main controller 6, and also includes an outer cover connecting bracket 11, an outer mesh cover 12, and a drum hoop 13; the outer cover connecting bracket 11 is connected to the support frame 10 through the drum hoop 13; the outer mesh cover 12 covers and is connected to the outer cover connecting bracket 11.

[0050] The passive radiator 7 , i.e. the drum surface, can also be connected to the support frame 10 and the outer cover connecting bracket 11 through the drum hoop 13 .

[0051] The sound outlet avoidance portion 14 is also provided on the support frame 10 and the outer cover connecting bracket 11, corresponding to the through hole of the sound outlet end of the first speaker 1;

[0052] The support frame 10 can be a shell structure that can be separated from top to bottom, and the outer cover connecting bracket 11 can be a shell structure that can be separated from left to right. The outer mesh cover 12 has a fine mesh through hole, so there is no need to set a through hole corresponding to the sound output end of the first speaker 1, which improves the appearance.

[0053] The drum hoop 13 is preferably provided with a decorative nail cap, and the outer mesh cover 12 is selected to be bright red, so that the whole speaker has the appearance of a Chinese red drum and is highly aesthetic.
