[0034] Embodiment 1.

[0035] Preferably, the desk - shaped sound speaker includes a box body 100 and a support structure 200. The box body 100 is fixedly connected to the support structure 200. The combination of the box body 100 and the support structure 200 can be reused for the purpose of a desk. The desk - shaped sound speaker further includes a sound structure 300. The sound structure 300 is partially built into the box body 100, and the sound structure 300 can be used to play home music, wherein:

[0036] The sound structure 300 includes a button module 310, a power amplifier module 320, two subwoofers 330, two midrange speakers 340, and two tweeters 350;

[0037] The cabinet 100 includes a top plate 110, a bottom plate 120, two partition plates 130, two baffle plates 140, and two front plates 150. The top plate 110, the bottom plate 120, the partition plates 130, and the baffle plates 140 form a first cavity 101 and a second cavity 102. The subwoofer 330 is located in the first cavity 101 and is fixedly connected to the bottom plate 120. The midrange speaker 340 and the tweeter 350 are both located in the second cavity 102 and are respectively fixedly connected to the front plate 150;

[0038] The cabinet 100 further includes a positioning plate 160. The positioning plate 160 and the partition plate 130 form a third cavity 103. The power amplifier module 320 is located in the third cavity 103. The button module 310 is embedded in the top plate 110 and is electrically connected to the power amplifier module 320.

[0039] Among them, the sound structure 300 further includes two sound guide tubes 380. The sound guide tubes 380 are located in the first cavity 101 and are fixedly connected to the bottom plate 120.

[0040] Among them, the sound guide tube 380 has a sound guide tube communication cavity 381. One end of the sound guide tube communication cavity 381 communicates with the first cavity 101, and the other end of the sound guide tube communication cavity 381 communicates with the external environment.

[0041] Among them, the sound structure 300 further includes two subwoofer grilles 331. The subwoofer grilles 331 face the subwoofers 330 and are detachably connected to the bottom plate 120.

[0042] Among them, the button module 310 includes a button housing 311 and a plurality of button bodies 312. The button bodies 312 are respectively embedded in the button housing 311.

[0043] Among them, the power amplifier module 320 includes a PCB board (not shown in the figure). The button bodies 312 are independently electrically connected to the PCB board. The PCB board is electrically connected to the subwoofer 330, the midrange speaker 340, and the tweeter 350. With the help of the PCB board, wireless connections such as Bluetooth can be realized, so as to transmit music through Bluetooth.

[0044] Among them, the material of the button body 312 is preferably silicone.

[0045] Among them, the material of the cabinet 100 is preferably wood.

[0046] Among them, the cabinet 100 further includes a drawer 170. The drawer 170 is slidably connected to the bottom plate 120.

[0047] Among them, the support structure 200 includes four support columns 210, and the support columns 210 are fixedly connected to the bottom plate 120.

[0048] Among them, the support structure 200 further includes four support column spacers 220.

[0049] The following elaborates on the technical prospects of the desk-shaped sound speaker disclosed in this embodiment.

[0050] 1. The tweeter 350 uses a 1" 25.4-core carbon fiber composite silk diaphragm, which improves the rigidity and damping of the treble, making the sound quality delicate and pure, and the restoration degree higher.

[0051] 2. The outer surface of the box body 100 has a carbon fiber layer, making the sound permeability better.

[0052] 3. The midrange speaker 340 uses a 4-inch speaker unit and an aluminum alloy cast aluminum chassis, which has strong rigidity and good heat dissipation. The midrange speaker 340 uses a high-performance magnet and a Kapton voice coil, enabling the speaker to have higher power, less distortion, a clean and full tone, fast speed, and strong rhythm.

[0053] 4. The woofer 330 is provided with a high-performance rubber surround. The cone uses an injection-molded grade polymer material, which has strong rigidity and good damping, and can effectively increase the bass radiation, making the low-frequency sound effect richer. The chassis has high strength, fast heat dissipation, and low distortion. The Kapton four-layer double voice coil is wound with high-temperature copper-clad aluminum wire, and the Y40 magnet provides a powerful output power for the speaker.

[0054] 5. The desk-shaped sound speaker combines the music playback function and the desk function, serving multiple purposes with one desk, effectively reducing space occupation.

[0055] Embodiment 2.

[0056] Based on the technical solution of Embodiment 1, the technical solution of Embodiment 2 further includes the following technical solutions.

[0057] Preferably, the top plate 110 is provided with a pressure sensor array (not shown in the figure). Through the linkage of the PCB board, the pressure sensor array and the button module 310, the user behavior recognition and automatic response are strengthened (as an example: automatically muting when it is detected that the load on the top plate 110 exceeds the threshold), improving the user experience.

[0058] Specifically, the pressure sensor array includes a plurality of pressure sensors, and the pressure sensors are evenly distributed inside the top plate 110.

[0059] Among them, the top plate 110 is preferably provided with two groups of linear pressure sensors, and the linear pressure sensors are distributed along the length direction of the top plate 110. Each linear pressure sensor is preferably provided with 4 pressure sensors. The distance between two adjacent pressure sensors (in the same linear pressure sensor) is consistent, so as to comprehensively and accurately sense the load change of the top plate 110.

[0060] Among them, the pressure sensor preferably adopts a thin-film pressure sensor. The PCB board is electrically connected to the pressure sensor, and the pressure sensor is attached to the inner surface of the top plate 110 to ensure firmness and not affect the appearance and strength of the top plate 110.

[0061] Among them, the desk-shaped speaker is preset with two usage scenarios, namely the learning scenario and the leisure scenario. The user can switch autonomously through the operation button module 310, and the desk-shaped speaker is default in the learning scenario.

[0062] Among them, when the desk-shaped speaker is in the learning scenario, the PCB board simultaneously obtains the pressure data from each pressure sensor. When the PCB board determines that the pressure data of at least one pressure sensor in the specified area satisfies the first pressure range and the duration of the pressure data exceeds the first time threshold (equivalent to the user starting to study at the desk), the PCB board stops outputting the drive signal to all speakers to achieve automatic muting (unless the user operates the button module 310 to manually adjust the state of the desk-shaped speaker).

[0063] As a supplementary explanation, the specified area is preferably the range of the top plate 110 directly opposite the drawer 170; that is, when the desk-shaped speaker is in the learning scenario, the PCB board only determines the pressure data of the pressure sensors in the range of the drawer 170 (it can be understood that the user usually studies at the desk in the range of the drawer 170), so as to exclude the following interferences: First, when items such as water cups and books are placed in the area outside the drawer 170, due to not distinguishing the position, it is misjudged that the user starts to study at the desk; Second, when items such as water cups and books are placed in the range of the drawer 170, due to not distinguishing the pressure magnitude (the pressure data of the pressure sensor when the user studies at the desk is different from that of the pressure sensor of items such as water cups; considering differences in user age, etc., the first pressure range is set, and the first pressure range can be manually adjusted by the button module 310), it is misjudged that the user starts to study at the desk.

[0064] Among them, when the desk-shaped speaker is in a leisure scenario, the PCB board simultaneously obtains the pressure data from each pressure sensor. When the PCB board determines that the pressure data of any one pressure sensor satisfies the second pressure range and the duration of the pressure data exceeds the second time threshold (equivalent to the user stopping studying at the desk or leaving the desk-shaped speaker), the PCB board outputs a driving signal to all the speakers to achieve automatic playback (unless the user operates the button module 310 to manually adjust the state of the desk-shaped speaker).

[0065] It is worth mentioning that the specific structures and other technical features of the power amplifier module 320 involved in this invention patent application should be regarded as the prior art. The specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features can be selected conventionally in the art and should not be regarded as the inventive points of this invention patent. This invention patent will not be further specifically elaborated.

[0066] For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
