[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] like Figure 1-Figure 4As shown, the present application provides an interesting decompression audio system 1, including a speaker 100, a display screen 200, a main board 300, a key mechanism 400 and a lighting board 500. The speaker 100 is used to vibrate and pronounce. The display screen 200 is used to display images. The main board 300 is electrically connected to the speaker 100 and the display screen 200. The main board 300 is used to control the speaker 100 to vibrate and pronounce. The main board 300 is also used to control the display screen 200 to display images. The key mechanism 400 is electrically connected to the main board 300. The key mechanism 400 is used to output different control signals to the main board 300. The lighting board 500 is electrically connected to the main board 300. The lighting board 500 is located below the key mechanism 400. The lighting mechanism can emit light of different colors according to different control signals.

[0027] It can be understood that when the button mechanism 400 of the above-mentioned fun decompression audio system 1 is working, it can output different control signals to the main board 300, thereby controlling the speaker 100 to vibrate and pronounce sounds, and can control the lighting panel 500 to illuminate different colors of light, thereby enhancing the interactive performance and fun of the fun decompression audio system 1, which is conducive to providing convenience for customers' use and operation in insufficient light environments, and meeting users' needs for relieving work pressure in various scenarios.

[0028] Specifically, in this embodiment, the lighting lamp board 500 includes a plurality of RGB lamp beads arranged in an orderly interval.

[0029] In addition, in another embodiment, the lighting panel 500 may also be formed by a plurality of LED lamp beads arranged in an orderly manner.

[0030] It should be noted that the lighting panel 500 can emit white light, or light of various colors such as red light, yellow light, blue light, green light, etc. The user can embed a control program in the main board 300 in advance so that when the key mechanism 400 is played, the lighting panel 500 can emit corresponding light.

[0031] In one embodiment, Figure 1 and Figure 4 As shown, the fun decompression audio 1 also includes a housing 600, a key control panel 700 and a plurality of control buttons 800. A housing space for accommodating the speaker 100, the key control panel 700 and the main board 300 is formed inside the housing 600. A through hole 610 is provided on the housing 600. The key control panel 700 is electrically connected to the main board 300. One end of the control button 800 is detachably inserted into the through hole 610 and can be electrically connected to the key control panel 700. The control button 800 is used to control the key control panel 800 to indirectly control the working state of the main board 300.

[0032] It can be seen that the control button 800 of the fun decompression audio system 1 is detachable, that is, the user can conveniently control the operation of the mainboard 300 through the control button 800 when in use, and can also remove the control button 800 from the shell 600 when not in use, which is conducive to saving space.

[0033] Furthermore, the fun decompression audio 1 also includes an electronic control module. The electronic control module includes an audio amplification and electroacoustic conversion drive module, a sound storage IC module, a sound recording MIC and control module, a recording playback and control device, and an infrared remote control receiving device. In this embodiment, the fun decompression audio 1 can be connected to an external mobile terminal through a Bluetooth module, and send a signal to the sound storage IC module through the APP of the mobile terminal to control the speaker 100 to play audio through the audio amplification and electroacoustic conversion drive module; it can also be connected to an external remote control through an infrared remote control receiving device, and the sound storage IC module and the audio amplification and electroacoustic conversion drive module can be controlled to work by receiving the signal sent by the remote control, so that the speaker 100 plays audio, and the sound recording MIC and control device and the recording playback and control device can also be called to call the recording and playback function of the fun decompression audio 1.

[0034] In one embodiment, Figure 4 As shown, a protrusion 611 is provided on the hole wall of the through hole 610. A recess 811 is provided on the periphery of the control button 800. When the protrusion 611 and the recess 811 are aligned and engaged, the control button 800 is electrically connected to the button control board 700.

[0035] It should be noted that when the protrusion 611 and the recessed portion 811 are aligned and engaged, the relationship between the protrusion 611 and the recessed portion 811 can limit the movement of the control button 800 in a direction away from the mainboard 300, thereby achieving connection between the control button 800 and the hole wall of the through hole 610.

[0036] It should also be noted that the raised portion 611 and / or the recessed portion 811 can be set as "a structure made of a material that is easily deformed when subjected to external force". For example, the raised portion 611 and / or the recessed portion 811 can be made of rubber, silicone, latex and other materials. Therefore, when it is necessary to remove the control button 800 from the housing 600, the user can apply an external force F to the control button 800 in a direction away from the button control board 700. Under the action of the external force F, the raised portion 611 and / or the recessed portion 811 can be deformed, and the raised portion 611 and the recessed portion 811 can be relatively displaced, so that the raised portion 611 and the recessed portion 811 are released from the clamping connection, completing the action of separating the control button 800 from the housing 600.

[0037] It can be understood that the number of control buttons 800 and through holes 610 can be adjusted according to actual needs. For example, when the number of through holes 610 is greater than the number of control buttons 800 and the number of control main boards 300 is 1, the user can insert the control button 800 into one of the through holes 610 according to actual needs, thereby issuing instructions to the key control board 700 and the main board 300. When other adjustments are required, the control button 800 needs to be pulled out of this through hole 610 and then inserted into other through holes 610, thereby issuing other instructions to the key control board 700 and the main board 300; when the number of through holes 610 is less than the number of control buttons 800, the extra control buttons 800 can be used as "spare buttons"; when the number of through holes 610 is the same as the number of control buttons 800, a control button 800 can be inserted into each through hole 610.

[0038] Specifically, in this embodiment, the number of the control buttons 800 and the number of the through holes 610 are both three. The three control buttons 800 are respectively used to send different working instructions to the button control board 700.

[0039] Specifically, in this embodiment, the three control buttons 800 are respectively used to control the fun decompression audio 1 to "play the next song", "play the previous song", and "switch / confirm".

[0040] Furthermore, the fun decompression audio system 1 is also provided with a volume knob 910 for controlling the volume of the speaker 100 .

[0041] In one embodiment, when the end of the control button 800 facing the key control board 700 contacts the key control board 700, the control button 800 is electrically connected to the key control board. When the end of the control button 800 facing the key control board does not contact the key control board, the control button 800 is electrically disconnected from the key control board.

[0042] It should be noted that a deformable electrical connection end is formed on the side of the key control board 700 facing the control key 800. When the protrusion 611 and the recess 811 are aligned and clamped, the end of the control key 800 facing the key control board 700 is electrically connected to the electrical connection end, and the electrical connection end can be forced to be depressed downward and deformed, which is beneficial to increase the electrical connection stability between the control key 800 and the key control board 700. When the protrusion 611 and the recess 811 are released from alignment and clamping, the control key 800 is disconnected from the electrical connection end, and the electrical connection end returns to a natural state.

[0043] Furthermore, the control button 800 includes a first section 810 and a second section 820. The end of the first section 810 away from the second section 820 can be electrically connected to the key control board. The first section 810 and the second section 820 are both arranged in a cylindrical structure. The outer diameter of the first section 810 is r1, the outer diameter of the second section 820 is r2, and the inner diameter of the through hole 610 is R, r1<R<r2.

[0044] It can be seen that the first section 810 can pass through the through hole 610 and can be electrically connected to the key control board 700 .

[0045] Furthermore, an anti-skid portion (not shown) is provided on the periphery of the second section 820. The anti-skid portion can increase the friction coefficient between the second section 820 and the user's hand (or other part used to adjust the control button 800), which is helpful to avoid slipping.

[0046] In one embodiment, Figure 1 As shown, the fun decompression audio system 1 further includes a buffering foot pad 920. One end of the buffering foot pad 920 is connected to the bottom of the housing 600, and the other end is used to abut against the external platform.

[0047] Specifically, in this embodiment, the material of the buffer pad 920 can be but is not limited to EPS foam board, polyethylene foam plastic EPE, polyurethane foam plastic, kraft paper, etc.

[0048] In one embodiment, Figure 1 As shown, the fun decompression audio device 1 further includes a conductive silicone 980. The conductive silicone 980 is disposed between the key mechanism 400 and the main board 300.

[0049] The conductive silicone 980 can improve the electromagnetic sealing performance and water vapor sealing performance between the key mechanism 400 and the mainboard 300 on the basis of providing good conductive performance.

[0050] In one embodiment, Figure 1 and Figure 2 As shown, the key mechanism 400 includes eight first keys 410 and seven second keys 420. A second key 420 is disposed between two adjacent first keys 410.

[0051] It can be seen that when the user presses the first button 410 and the second button 420, different control signals can be output to the mainboard 300 respectively, so that the speaker 100 can vibrate and make corresponding sounds, and the display screen 200 can display corresponding images. That is, the user can produce different interactive effects with the speaker 100 and the display screen 200 by manipulating the first button 410 and the second button 420, thereby helping the user to relieve stress to a certain extent, which is conducive to increasing the richness of the user's entertainment activities and meeting the user's needs to release work pressure.

[0052] It should be noted that the "control signal" in this application is used to control the operation of the mainboard 300. The arrangement of the first button 410 and the second button 420 is similar to the arrangement of piano keys, that is, the first button 410 is a white key and the second button 420 is a black key. The user can play the first button 410 and the second button 420 in various ways according to their actual needs, so that the speaker 100 emits corresponding music, thereby realizing "interaction between the user and the sound", thereby enhancing the richness of the user's entertainment activities and meeting the user's need to release work pressure.

[0053] In one embodiment, the image displayed on the display screen 200 includes at least one of a clock, a calendar, a photo, and an emoticon package.

[0054] It can be understood that different image information is preset in the motherboard 300, and each button corresponds to a different image. For example, when a user presses a first button 410 (or a second button 420), the first button 410 (or the second button 420) sends a corresponding instruction to the motherboard 300, and the motherboard 300 controls the display screen 200 to display image A; when the user presses another first button 410 (or the second button 420), the first button 410 (or the second button 420) sends a corresponding instruction to the motherboard 300, and the motherboard 300 controls the display screen 200 to display image B, and so on.

[0055] It should also be noted that the number of the first buttons 410 and the second buttons 420 is not limited here, that is, the manufacturer can adjust the number of the first buttons 410 and the second buttons 420 according to actual needs.

[0056] It can also be understood that, when other conditions remain unchanged, the more the number of the first buttons 410 and the second buttons 420 is, the larger the volume of the interesting decompression speaker 1 is. Therefore, in order to ensure that the interesting decompression speaker 1 has enough melodies (or songs) and is easy to carry, the number and arrangement of the first buttons 410 and the second buttons 420 need to be optimized to a certain extent.

[0057] Specifically, in this embodiment, the number of first keys 410 is 8, the number of second keys 420 is 7, and one second key 420 is provided between two adjacent first keys 410. The first key is a standard octave piano note, and the second key is a high seventh note.

[0058] In one embodiment, a communication module is provided on the mainboard 300. The communication module is used to wirelessly connect to an external device so that the external device can send a control signal to the mainboard 300.

[0059] It should be noted that the communication module includes a Bluetooth controller. When in use, the mobile terminal and the Bluetooth controller are connected via Bluetooth, and then the user can generate an image to be displayed on the mobile terminal, such as time, numbers, alarm clock patterns, light bulb patterns, lines of song rhythm, etc., to display the current function or state of the fun decompression audio 1, and transmit the image to the Bluetooth controller, so that the Bluetooth controller can display the image that the user wants to display on the display screen 200, which has the characteristics of simple structure and low cost.

[0060] In one embodiment, the mainboard 300 includes a chip and a circuit board. The display screen 200 and the circuit board are both connected to the chip for communication. The chip is used to control the display screen 200 to display a corresponding image according to the working state and the user's control instruction.

[0061] In one embodiment, the display screen 200 is an LCD screen having a plurality of display units.

[0062] Furthermore, in this embodiment, the display screen 200 includes a lens 210 , a buffer foam 220 , a screen frame 230 and a screen body 240 .

[0063] It should be noted that the display screen 200 in the present application can also be a screen composed of multiple LED matrix lights, wherein the display screen 200 can display corresponding multimedia information under the control of the mainboard 300. The multimedia information here includes but is not limited to text, pictures, animations, and video images.

[0064] The user can set the text / picture / animation / video image that he / she wants to display on the display screen 200 through the mobile phone, and after setting, send it to the main board 300 through the communication module. When the user plays the first button 410 and / or the second button 420, the text / picture / animation / video image is played on the display screen 200. When the user feels this kind of interaction, he / she will feel happy and comfortable, which is conducive to satisfying the user's need to relieve work pressure.

[0065] In addition, the LED matrix lights in the display screen 200 can be RGB lights to display various color patterns or animations or texts or expressions, etc., to increase the fun. In addition, the type of music played by the fun decompression audio 1 can also be set to display animations or images that match the music type.

[0066] In one embodiment, Figure 1 As shown, the fun decompression audio system 1 further includes a power supply mechanism 970. The power supply mechanism 970 is located in the accommodation space and is electrically connected to the mainboard 300.

[0067] It should be noted that the power supply mechanism 970 in the present application can be a rechargeable battery, and its charging / data port is a USB2.0 or 3.0 interface, or a TYPE-C interface, which is used to connect or charge an external electronic device via a data cable; the circuit board includes a charging IC310 connected to the battery and used for power conversion, and the display is electrically connected to the charging IC310 and is used to indicate the battery charging status during the battery charging process.

[0068] Furthermore, in one embodiment, the outer surface of the housing 600 is also provided with an earphone jack and a USB interface that are connected to the chip for communication. The chip can convert the Bluetooth data signal of the external device received by the Bluetooth module into a digital signal, and process the digital signal into an audio signal, and finally the speaker 100 makes a sound according to the audio signal.

[0069] The headphone jack can be used for inserting the headphone plug of an external audio device, so that the external audio device can produce sound through the speaker 100, thereby improving the application adaptability and expansibility of the fun decompression audio 1.

[0070] The USB interface can be connected to external electronic devices through a USB data cable, which is conducive to improving the adaptability and expandability of the fun decompression speaker 1. At the same time, the battery can be charged through the USB interface by using a charger. The battery can be charged conveniently and quickly without removing the battery, which is conducive to further improving the battery life and ease of use of the fun decompression speaker 1.
