Description

Technical Field

[0001] The utility model relates to the field of audio equipment, in particular to an audio device. Background Art

[0002] Speaker devices are generally composed of speaker units and cabinets. The speaker unit is the sound-generating component, and the cabinet complements the speaker unit and plays a role in correcting the sound. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electron energies are transmitted to the coil, the coil generates a kind of energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electron energy changes at any time, the speaker coil will move forward or backward, so the speaker paper plate will move with it. These actions change the density of the air and produce sound.

[0003] Since the speaker unit is in the box and connected to the box, the vibration of the speaker unit will inevitably drive the vibration of the box, and the vibration of the box will cause sound distortion and degradation of sound quality. Therefore, it is currently necessary to reduce the vibration of the sound box. Summary of the invention

[0004] Based on this, it is necessary to provide an audio device to address the problem that the box of the audio device vibrates due to the vibration of the speaker during use, including: a middle shell, having an upper cavity, which can accommodate fluid; an upper shell, which is covered on the middle shell and has a recessed portion, in which a liquid outlet and a liquid inlet connected to the upper cavity are opened; a speaker assembly, fixedly arranged on the middle shell; a submersible pump, arranged in the upper cavity, and its outlet is connected to the liquid inlet so as to transport the fluid in the upper cavity to the recessed portion; a driving circuit board, fixedly arranged on the middle shell and electrically connected to the speaker assembly and the submersible pump respectively; a floating object, floating on the fluid in the upper shell.

[0026] See also Figure 1 As shown, the acoustic device 100 is square in shape as a whole, and includes a middle shell 20 and an upper shell 11 covering the top of the middle shell 20, and the middle shell 12 can be made of a transparent material. In other embodiments, the acoustic device can also be set to a cylindrical, conical or spherical shape. Among them, the upper shell 10 is a spherical shell or a conical shell, which has a recessed portion 11, and the recessed portion 11 is provided with a liquid outlet 13 and a liquid inlet 12 connected to the upper cavity 22. In this embodiment, the liquid outlet 13 is arranged near or at the bottom of the recessed portion 11, and the liquid inlet 12 is arranged near or at the top of the recessed portion 11. The fluid flows into the recessed portion 11 from the liquid inlet 12, and flows out from the liquid removal hole 12 at the bottom under the action of gravity. In other embodiments, the liquid outlet 13 and the liquid inlet 12 can also be arranged at other positions of the recessed portion.

[0027] See also Figure 2-3As shown, the middle shell 20 has an upper cavity 22 on the upper side, and a left cavity 21 and a lower cavity 23 on the left side, wherein the upper cavity, the left cavity 21 and the lower cavity 23 are separated by partitions in pairs, so that each cavity is independent of each other. The upper cavity 22 can contain a fluid, which can be a damping fluid or water or other fluids. When it is a damping fluid, the damping fluid can be a fluid with a certain viscosity, such as hydraulic oil, methyl silicone oil, glycerin or an aqueous solution. There is no restriction on the specific type of the damping fluid, as long as the damping function can be achieved to consume vibration energy. A submersible pump 30 is also provided in the upper cavity 22, whose inlet is immersed in the fluid and whose outlet is connected to the liquid inlet hole 12, so as to transport the fluid in the upper cavity 22 to the recessed portion 11. Specifically, the inlet of the submersible pump 30 is directly located in the fluid so that the damping fluid can be sucked into the submersible pump 30. In addition, filter cotton and filter screen (not shown) are fixedly installed at the inlet of the submersible pump 30 in sequence, and the filter screen is arranged at the outermost layer to fix and wrap the filter cotton. The outlet of the submersible pump 30 is connected to one end of the connecting pipe 40, and the other end of the connecting pipe 40 is connected to the liquid inlet hole 12. The speaker assembly 70 is fixedly arranged in the left cavity 21 of the middle shell 20, and the driving circuit board 50 is arranged in the lower cavity 23 of the middle shell 20, and is electrically connected to the speaker assembly 70 and the submersible pump 30 respectively.

[0028] See also Figure 2 As shown, the opening direction of the liquid outlet 13 is arranged along the tangent direction of the recessed portion 11. The tangent direction in this embodiment refers to the tangent direction of the circular cross section of the recessed portion 11 at the position of the liquid outlet 13. Since the opening direction of the liquid outlet 13 is arranged along the tangent direction, the fluid is sprayed into the recessed portion along the tangent direction B, thereby realizing the rotation of the fluid and generating a vortex in the recessed portion 11, that is, the fluid rotates relative to the recessed portion 11.

[0029] Continue to see Figure 3 As shown, when the fluid in the upper shell 10 has a vortex, a fluid vortex surface 120 is generated, and the floating object 130 floats on the fluid vortex surface 120 and rotates relative to the upper shell 10 under the drive of the vortex. The floating object 10 can be a square (rectangular parallelepiped or cube), or a rotating body (sphere, cylinder or cone); the floating object 10 can be a container with an inner cavity, or a solid body; the floating object 10 can be made of plastic, metal or ceramic. There is no specific limitation on the shape and material of the floating object 10, as long as it can float on the fluid in the upper shell 10.

[0030] See also Figure 4As shown, a mesh unit 90 is also fixedly connected to the opening of the left cavity 21 of the middle shell 20, and a speaker assembly 70 is fixedly connected to the side of the mesh unit 90 close to the middle shell 20, and the speaker assembly 70 includes at least one speaker unit. The mesh unit 90 is covered at the opening of the left cavity 21, thereby partially closing the opening of the left cavity 21, and making the speaker assembly 70 located in the left cavity 21. The lower shell 80 is fixedly connected to the lower end of the middle shell 20, and the lower shell 80 closes the opening of the lower cavity 23, so that the lower cavity 23 is a closed cavity. In this embodiment, closed is relative to having an opening, and does not mean that the cavity is completely sealed without any gaps or openings. A passive radiator 100 corresponding to the speaker assembly 70 is fixedly arranged on the top surface of the lower shell 80. Specifically, the passive radiator 100 is arranged directly below the speaker unit 20, and its number is the same as the number of speaker units and corresponds one to one. The passive radiator 100 cooperates with the speaker unit to enhance the bass effect of the sound. A plurality of buffers 110 are provided on the bottom surface of the lower shell 80. The buffers 110 are used to buffer the vibration of the entire audio device. In this embodiment, four buffers 110 are provided, which are respectively provided at the four corners of the lower shell 80. In addition, a wireless induction coil 31 is provided at the bottom of the submersible pump 30.

[0031] See also Figure 3 , 5 As shown, a wireless charging coil 60 wirelessly connected to the driving circuit board 50 is provided on the upper side of the driving circuit board 50. The wireless charging coil 60 is coupled with the wireless induction coil 31 to realize the electrical connection between the submersible pump 30 and the driving circuit board 50, thereby realizing the power supply of the submersible pump 30 by the driving circuit board 50.

[0032] A silicone ring 120 is also provided at the connection between the upper shell 10 and the middle shell 20. The silicone ring 120 can absorb and buffer vibrations, preventing the vibrations on the middle shell 20 from being transmitted to the upper shell 10, thereby avoiding vibrations at the connection between the middle shell 20 and the upper shell 10, thereby avoiding abnormal sounds and distortion.

[0033] See also Figure 1 , 3-5, the operating principle of the submersible pump 30 is explained. The outlet of the submersible pump 30 is connected to the liquid inlet 12 through the connecting pipe 40. The opening direction of the liquid inlet 12 is along the tangential direction of the upper shell 11. When the submersible pump 30 is running, the fluid is sucked into the interior of the submersible pump 30 from the inlet thereof, and is pumped from the liquid inlet 12 to the recessed portion 11 through the connecting pipe 40. Since the opening direction of the liquid inlet 12 is parallel or substantially parallel to the tangential direction of the upper shell 11, the fluid flowing out of the liquid inlet 12 will be injected into the recessed portion 11 along the tangential direction, forming a water vortex effect, increasing the water flow speed, accelerating the evaporation of water, and improving the humidification effect. The fluid entering the recessed portion 11 will flow out from the liquid outlet 13 under the action of gravity and return to the upper cavity 22 of the middle shell, thereby realizing the circulation of the fluid in the upper cavity 22 of the middle shell and the recessed portion 11.

[0034] The utility model utilizes the damping effect of the fluid stored in the recessed portion 11 in the upper shell 10 and the upper cavity 22 in the middle shell 20, as well as the weight of the fluid itself, to reduce the vibration of the outer shell assembly (including the middle shell, the upper shell and the bottom shell), thereby reducing the sound distortion of the audio device 100 and improving the sound quality of the audio device 100.

[0035] In addition, since the float 130 is provided in the fluid of the upper shell 10, the float 130 will change the pressure of the fluid and change the weight of the filler filled in the recessed portion 11 of the upper shell 10 (the weight of the filler is the sum of the weight of the fluid and the weight of the float), thereby further improving the vibration reduction effect without increasing the fluid. In addition, floats of different weights can be selected according to actual needs, so that the vibration reduction effect can be adjusted according to actual needs. Furthermore, the setting of the float can also change the rotation speed of the vortex, so that the humidification effect of the fluid can be adjusted according to needs.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
