Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. 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.

[0034] Please refer to the attached document. Figures 1-6 This utility model proposes a novel cajon drum. The housing 1 includes a front panel 11, a back panel 12, and a plate 16. The housing 1 is equipped with a control device 2 and a sounding string module 7, wherein the sounding string module 7 is located on one side of the front panel 11. The front panel 11 is equipped with multiple sensing elements 3. The sensing elements 3 are electrically connected to the control device 2. The back panel 12 is equipped with a sound hole 121 and a first mounting hole 122. The sound hole 121 is used to emit sound, and the first mounting hole 122 is used to place the control device 2.

The control device 2 is equipped with several plug-in interfaces 211, which are used to electrically connect to external devices. The control device 2 is also equipped with a signal conversion module and a signal processing module. The signal conversion module is used to convert the multi-point signal intensity and the position information of the striking point collected by the sensing elements 3 into electrical signals. The signal processing module is used to process the electrical signals and play them out by the audio output device 4.

[0035] In this embodiment, the enclosure 1 is composed of a front panel 11, a back panel 12, and a plate 16; a control device 2 and a rattle module 7 are provided inside the enclosure 1. The control device 2 is located near the back panel 12 inside the enclosure 1, and the rattle module 7 is located near the front panel 11. The front panel 11 is provided with sensing elements 3, including a region sensing element 31 and a pressure sensing element 32. The region sensing element 31 is located on the surface away from the interior of the enclosure 1 or embedded in the front panel 11 of the cajon drum. The front panel 11 has a high-frequency region 111 and a low-frequency region 112, and the region sensing element 31 is specifically located within the high-frequency region 111 and the low-frequency region 112. The pressure sensing element 32 is located on the surface near the interior of the enclosure 1 and is located within the high-frequency region 111 and the low-frequency region 112, respectively. The area sensing element 31 and the pressure sensing element 32 are electrically connected to the signal conversion module. The area sensing element 31 is used to detect the position information of the tapping point on the panel 11, and the pressure sensing element 32 is used to detect the magnitude of the pressure applied to the panel 11. An audio output device 4 is located at the bottom of the housing 1. The audio output device 4 is electrically connected to the signal processing module. The signal processing module integrates the signals from the signal processing module, and the integrated sound effect is output to the outside world through the audio output device 4 to achieve stable signal output without interference.

[0036] The control board 21 on the control device 2 is provided with several plug-in interfaces 211 to facilitate electrical connection with external devices. In one embodiment, the plug-in interfaces 211 include, but are not limited to, MIDI interfaces. Through the MIDI interface, the cajon drum can be connected to music game software or digital music production tools to achieve interaction with virtual instruments, providing users with more possibilities for entertainment and creation. Simultaneously, microphone input is also supported, allowing the sound of human voices or other instruments to be mixed with the sound of the cajon drum for recording. This not only facilitates recording and mixing but also provides more possibilities for live performances.

[0037] In another embodiment, the cajon drum also features a Bluetooth connectivity device that can connect to mobile phones, computers, or other Bluetooth devices. Users can play music via Bluetooth or use it in conjunction with a digital audio workstation (DAW), expanding the cajon drum's application scenarios.

[0038] Please refer to Figure 2 and Figure 4 The sensing element 3 includes at least a region sensing element 31 and a pressure sensing element 32. The region sensing element 31 is disposed on the panel 11 and is used to detect the position of the tapping point within the region of the panel 11. The pressure sensing element 32 is disposed on the other side of the panel 11 and is used to detect the magnitude of the force. The region sensing element 31 and the pressure sensing element 32 are electrically connected to the signal conversion module respectively.

[0039] In a specific implementation: the sensing element 3 is disposed on the panel 11. The sensing element 3 includes a region sensing element 31 and a pressure sensing element 32. The region sensing element 31 is disposed on the outer side of the panel 11, and the pressure sensing element 32 is disposed on the inner side of the panel 11. The region sensing element 31 is disposed in the high-frequency region 111 and the low-frequency region 112, respectively, and the pressure sensing element 32 is disposed in the high-frequency region 111 and the low-frequency region 112 of the panel 11, respectively. The region sensing element 31 includes, but is not limited to, piezoelectric sensors, resistive pressure sensors, capacitive pressure sensors, and fiber optic pressure sensors.

[0040] In one embodiment, the area sensing element 31 is a piezoelectric thin-film sensor, which is a device capable of converting mechanical pressure into an electrical signal. The piezoelectric thin-film sensor has high sensitivity and can detect minute pressure changes in the panel 11. The cajon's panel 11 is a large flat surface, and the player will strike it with different forces at different locations to produce different sound effects. The piezoelectric thin-film sensor can be embedded in the high-frequency region 111 and low-frequency region 112 of the cajon's panel 11, or attached to the back of the panel 11 (i.e., the side of the panel 11 near the interior of the housing 1) to achieve optimal signal detection.

[0041] The cajon drum controls volume by detecting the force applied to the panel 11 using a pressure-sensing element 32 on the panel 11, and controls rhythm by controlling frequency. The pressure-sensing element 32 includes, but is not limited to, a buzzer. The buzzer is a highly sensitive element capable of responding to minute vibrations. By monitoring the vibration state of the buzzer, the force and frequency of the strike can be accurately detected, even very slight strikes can be accurately captured. The greater the force of the strike, the greater the amplitude of the electrical signal generated by the buzzer, thus allowing the detection of the force and mapping it to different volume levels. The vibration signal from the buzzer is converted into an electrical signal, processed by the signal processing module, and then output to the outside world through the audio output device 4 to achieve stable signal output.

[0042] Please refer to Figure 2 and Figure 4 The panel 11 is provided with a high-frequency area 111 and a low-frequency area 112, and each of the high-frequency area 111 and the low-frequency area 112 is provided with an area sensing element 31.

[0043] In practical implementation: The panel 11 is provided with a high-frequency area 111 and a low-frequency area 112, and piezoelectric film sensors are respectively set in the high-frequency area 111 and the low-frequency area 112. The piezoelectric film sensors are used to detect the mechanical pressure on the panel 11. The mechanical pressure received by the piezoelectric film sensors in the high-frequency area 111 and the low-frequency area 112 is converted into electrical signals and sent to the signal processing module for accurate identification of whether it is the high-frequency area 111 or the low-frequency area 112. Multiple area sensing elements 31 and pressure sensing elements 32 synchronously collect the impact point position information and pressure signals, which can avoid the phenomenon of resonance reverberation caused by vibration in the traditional wooden cabinet 1, thereby improving the sound quality and playing accuracy.

[0044] Please refer to Figure 1 and Figure 3 The control device 2 includes a control plate 21 and a cover plate 22. The cover plate 22 is connected to the back plate 12 and the control plate 21 respectively. The edge of the first mounting hole 122 is provided with a first groove 123. The cover plate 22 is located in the first groove 123 and is connected to the first groove 123. The cover plate 22 is provided with a placement groove 221. The bottom of the placement groove 221 passes through the first mounting hole 122 and abuts against the control plate 21. The placement groove is provided with a plurality of third through holes. The connector interface 211 passes through the third through holes 222 and protrudes from the bottom surface of the placement groove 221.

[0045] In specific implementation: the control device 2 includes a control plate 21 and a cover plate 22. The back plate 12 is provided with a sound hole 121 and a first mounting hole 122. The first mounting hole 122 is located below the sound hole 121 and is rectangular. A first groove 123 is provided at the edge of the first mounting hole 122, and the opening of the first groove 123 faces the outside of the housing 1. The first groove 123 is mainly used to place the cover plate 22. Specifically, the flange of the cover plate 22 is located in the first groove 123 and is fixedly connected to the first groove 123. The bottom of the first groove 123 passes through the first mounting hole 122 and abuts against the control plate 21 inside the housing 1.

[0046] The control board 21 of the control device 2 is located inside the housing 1, and the cover plate 22 is located on the back plate 12 of the housing 1. The cover plate 22 has a placement groove 221, which abuts against the control board 21 inside the housing 1. The bottom of the placement groove 221 is also provided with several third through holes 222. The control board 21 has several plug-in interfaces 211. The plug-in interfaces 211 pass through the third through holes 222 and protrude from the bottom surface of the placement groove 221 to facilitate electrical connection with external devices. The placement groove 221 is recessed into the housing 1 to prevent the plug-in interfaces 211 from being damaged or poorly contacted due to external impact or accidental pressure, resulting in unstable signals or equipment failure. The connector interface 211 is positioned below the surface of the back panel 12 of the enclosure 1, preventing it from being directly impacted by external forces and extending the equipment's service life. When the enclosure 1 is subjected to external pressure, the connector interface 211 remains within the placement groove 221, reducing the risk of collisions or scratches. Furthermore, the recessed design of the placement groove 221 eliminates the protrusion of the interface area, creating a more harmonious design with the enclosure 1's overall shape, resulting in a more streamlined and cleaner appearance and enhancing the equipment's aesthetics.

[0047] Please refer to Figure 1 and Figure 5 The panel 16 includes a side panel 13 and a top panel 14. The audio output device 4 includes at least a speaker assembly 41 and a cavity 42. The cavity 42 is located inside the housing 1. The side of the cavity 42 near the side panel 13 is provided with a first through hole 421. The side panel 13 is provided with a second mounting hole 131. The first through hole 421 abuts against the side panel 13 and communicates with the second mounting hole 131. The surface of the cavity 42 opposite to the top panel 14 is provided with a second through hole 422 for transmitting sound.

[0048] In practical implementation: The audio output device 4 is located at the bottom of the enclosure 1. The audio output device 4 includes at least two sets of speaker assemblies 41 and a cavity 42. The speaker assemblies 41 are respectively located on the side plates 13 of the enclosure 1. The side plates 13 of the enclosure 1 have second mounting holes 131 located at the bottom. The cavity 42 is hollow, forming a resonance chamber. By controlling the size and shape of the cavity 42, the timbre, volume, and frequency response of the instrument can be adjusted. The sound effect of the cajon drum relies on the resonance of the hollow cavity 42; the sound quality of the speaker 411 is optimized for low-frequency response through reflection and resonance within the hollow cavity 42. The two ends of the cavity 42 each have first through holes 421, which abut against the side plates 13 and communicate with the second mounting holes 131 on the side plates 13. The cavity 42 can guide the sound waves generated by the drumhead strikes, allowing them to propagate through specific channels and optimizing the bass response. Low-frequency effects are enhanced by controlling airflow, resulting in deeper and richer bass. The first through-hole 421 connects to the speaker 411. When the drumhead vibrates, the air inside the cavity 42 interacts with the speaker 411 through the through-hole, generating bass resonance and deepening the bass. The two ends of the cavity 42 are connected to the speakers 411, allowing the speaker system to distribute sound more evenly and enhancing the stereo effect. When the cajon drum is struck, sound propagates through the cavity 42, causing the low-frequency resonance of the left and right speakers 411 to be synchronized, enriching the listening experience.

[0049] The surface of the cavity 42 opposite to the top plate 14 is provided with a second through-hole 422. Specifically, the second through-hole 422 consists of two circular through-holes of different sizes, used to adjust the low-frequency response of different frequency bands, making the bass more balanced and preventing it from being too muddy or monotonous. The larger through-hole enhances lower frequencies, making the bass deeper and fuller; the smaller through-hole enhances higher low frequencies, making the sound tighter and clearer. This balances the low-frequency response, preventing the bass from being overly muddy or lacking power. The vibration of the speaker 411 and the drumhead causes airflow within the cavity 42. If the airflow channel is not designed properly, it can produce wind noise or uneven airflow. The two second through-holes 422 of different sizes allow air to flow freely under different pressure conditions, avoiding eddy noise at high sound pressure levels (high volume) and ensuring clear sound quality.

[0050] Among them, the cajon drum with built-in speaker component 41 significantly improves the volume and sound quality, making it more suitable for use in various occasions (such as stage performances, recording studios or home practice). At the same time, it solves the problem that the traditional cajon drum has a small volume and cannot meet the needs of live performances or recordings.

[0051] Please refer to Figure 1The speaker assembly 41 includes a speaker 411 and a mesh cover 412. The speaker 411 is partially disposed on the second mounting hole 131, and one side of the speaker 411 is recessed into the housing 1 and located in the cavity 42.

[0052] In specific implementation: the speaker assemblies 41 are respectively located on the left and right sides of the enclosure 1, and are on the same axis as the cavity 42 inside the enclosure 1. The speaker assembly 41 includes a speaker 411 and a mesh cover 412. The mesh cover 412 is mainly used to protect the speaker 411, which can effectively prevent dust, foreign objects or accidental contact from damaging the speaker 411 and extend the service life of the speaker 411. The speaker 411 is located at both ends of the cavity 42, and one end of the speaker 411 protrudes into the cavity 42, so that the diaphragm of the speaker 411 is located inside the cavity 42. The diaphragm of the speaker 411 vibrates and resonates with the air inside the cavity 42 to produce sound, which optimizes the sound transmission path, reduces sound loss, and makes the sound quality clearer.

[0053] Please refer to Figure 1 and Figure 2 A second groove 132 is provided on the side of the second mounting hole 131 away from the inside of the enclosure 1, and the radius of the second groove 132 is larger than the radius of the second mounting hole 131. The opening of the second groove 132 faces the outside of the enclosure 1. The speaker 411 is partially located at the bottom of the second groove 132 and is fixedly connected to the second groove 132. The mesh cover 412 is located in the second groove 132 and fits against the side wall of the second groove 132 to protect the speaker 411.

[0054] In specific implementation: The side panels 13 of the enclosure 1 are respectively provided with second mounting holes 131. On the side of the second mounting holes 131 away from the interior of the enclosure 1 (i.e., the surface of the outer side panel 13 of the enclosure 1), a second groove 132 is provided, and the radius of the second groove 132 is larger than the radius of the second mounting holes 131. The second groove 132 is used to place the speaker assembly 41. The speaker assembly 41 includes a speaker 411 and a mesh cover 412. The speaker 411 is located at the bottom of the second groove 132 and is fixedly connected to the bottom of the second groove 132 so that the speaker 411 can be fixed to the side panel 13. The mesh cover 412 is located inside the second groove 132 and fits against the side wall of the second groove 132, so that the speaker 411 can be completely covered by the mesh cover 412. The mesh cover 412 is mainly used to protect the speaker 411 and prevent damage to the speaker 411 from dust, foreign objects, or accidental contact.

[0056] In specific implementation: the panel includes side panels 13, top panels 14, and bottom panels 15; the front panel 11 is fixedly connected to the top panel 14, side panels 13, and bottom panels 15 respectively via first fixing strips 5; the back panel 12 is fixedly connected to the top panel 14, side panels 13, and bottom panels 15 respectively via second fixing strips 6. The bottom panel 15 is provided with foot pads 151 to provide support for the cabinet 1. The support of the foot pads 151 allows the cajon drum to produce a clearer sound, a more powerful bass, and reduces noise caused by unnecessary vibrations.

[0057] Please refer to Figure 1 and Figure 6 The rattle module 7 includes a rattle 71, an adjusting block 72, and a stud 73. One end of the rattle 71 is fixed to the first fixing strip 5 near the top plate 14, and the other end is connected to the adjusting block 72. It is also fixed to the bottom of the housing 1 by the stud 73. The stud 73 is also used to adjust the tension of the rattle 71.

[0058] In practical implementation: the rattle module 7 is located inside the housing 1, specifically on the side near the panel 11. The rattle module 7 includes a rattle 71, an adjusting block 72, and a stud 73.
