Description

Technical Field

[0001] This invention relates to the field of audio equipment, and in particular to an audio system. Background Technology

[0002] A speaker enclosure typically consists of a speaker unit and a cabinet. The speaker unit is the component that produces sound, while the cabinet complements the speaker unit and corrects the sound. The principle of sound production by a speaker unit is the conversion of electrical energy into sound. When different amounts of electronic energy are transmitted to the coil, the coil generates energy that interacts with the magnetic field of the magnet. This interaction causes the diaphragm to vibrate. Because the electronic energy is constantly changing, the speaker coil moves forward or backward, and thus the speaker diaphragm moves accordingly. These movements change the density of the air, thereby producing sound.

[0003] Because the speaker unit is located inside and connected to the cabinet, the vibration of the speaker unit will inevitably cause the cabinet to vibrate, which in turn leads to sound distortion and a decrease in sound quality. Furthermore, cabinet vibration can generate noise and cause the cabinet itself to shift. Currently, common methods to reduce speaker cabinet vibration include thickening, reinforcing, structural optimization, and optimizing the shell material; however, these methods generally have limited vibration reduction effects.

[0031] See Figure 1The structure of the speaker 100 in this embodiment is described below. The speaker 100 in this embodiment is generally cylindrical, comprising an upper shell 11, a middle shell 12, and a main shell 13 connected in sequence. The upper shell 11 has a recess 115 recessed towards the middle shell 12. A through-hole 111 (liquid outlet) and a through-hole 110 are provided on the upper shell 11. The liquid outlet 111 is located near or at the bottom of the recess 115, and the liquid inlet 110 is located near or at the top of the recess 115. In other embodiments, the speaker may be configured in other shapes, such as rectangular, rhomboid, or conical.

[0032] See Figure 2 The housing assembly 10 of the speaker 100 in this embodiment will be described below. The housing assembly 10 includes an upper shell 11, a middle shell 12, a main shell 13, and a lower shell 14 connected in sequence. The middle shell 12 may be made of a transparent material and is a cylindrical structure with a bottom plate that closes the bottom and an open top. The upper shell 11 covers the upper opening of the middle shell 12. Since the bottom of the middle shell 12 is closed, a middle shell receiving space 121 is formed, which is filled with 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. The specific type of damping fluid is not limited, as long as it can achieve the damping function to dissipate vibration energy. The upper end of the main shell 13 is closed or partially closed, while the lower end has an opening, thus forming a downwardly open inner cavity. A power interface 1312 is provided on the outer periphery of the main shell 13. Silicone rings 15 are provided at the connection points between the upper shell 11 and the middle shell 12, and at the connection points between the middle shell 12 and the main shell 13. The silicone rings 15 absorb and buffer vibrations, preventing vibrations from the main shell 13 from being transmitted to the middle shell 12 and the upper shell 11, and preventing abnormal sounds and distortions caused by vibrations at the connection points of the main shell 13, middle shell 12, and upper shell 11. Multiple lower shell connecting rods 141 are fixedly provided on the upper side of the lower shell 14, enabling a fixed connection between the lower shell 14 and the main shell 13.

[0033] See Figure 3The structure of the audio system in this embodiment will be further described below. A mounting bracket 70 is fixedly connected to the lower side of the upper shell 11. The mounting bracket 70 includes a mounting panel and a connector 71 fixed to the mounting panel. The mounting panel is fixedly connected to the lower side of the upper shell 11 via a connecting rod. A pump body 83 is disposed within the middle shell receiving space 121 of the middle shell 12. The pump body 83 is a submersible pump or other liquid pump. The pump body 83 is mounted on the mounting bracket 70 to achieve a fixed connection with the upper shell 11, thus suspending it within the middle shell receiving space 121. The upper end face of the pump body 83 is fixedly connected to the mounting panel, and the outlet pipe 831 of the pump body 83 is inserted into the connector 71 and communicates with the connector 71. In other embodiments, the mounting bracket 70 may not be provided, and the pump body 83 may be directly disposed on the bottom plate of the middle shell 12. Since the pump body 83 in this embodiment is a submersible pump, its inlet is directly located in the damping fluid, thereby allowing the damping fluid to be drawn into the pump body 83. A filter cotton 82 and a filter screen 81 are fixedly installed at the inlet of the pump body 83. The filter screen 81 is placed on the outermost layer to fix and wrap the filter cotton 82.

[0034] See also Figure 3 As shown, one end of the cover 90 is connected to the upper shell 11, and the other end is connected to the bottom of the middle shell 12, thus being disposed within the middle shell receiving space 121 of the middle shell 12. Multiple filter holes are provided on the side wall of the cover 90 to achieve communication between its internal cavity and the middle shell receiving space 121, facilitating the flow of damping fluid into the cover 90. When the cover 90 is installed, the fixing frame 70 and the pump body 83 are both disposed within the cover 90, meaning the cover 90 completely encloses the pump body 83. When water is used as the damping fluid, the middle shell 12 is configured as a cylindrical transparent shell, allowing users to raise fish inside. In this case, to prevent fish or aquatic plants from clogging the inlet of the pump body 83, the cover 90 protects the pump body 83. The filter holes on the cover 90 prevent fish or aquatic plants from being sucked into the pump body 83, thus providing protection. Furthermore, the filter screen 81 and filter cotton 82 further filter the damping fluid, further filtering out foreign objects entering the pump body 83. In addition, a wireless induction coil (not shown in the figure) is provided at the bottom of the pump body 83, which is used to power and drive the pump body 83. Furthermore, a UV lamp (not shown in the figure) is installed at the internal water inlet of the pump body 86. Multiple silicone pads 142 are provided at the bottom of the lower shell 14, which are used for vibration damping and cushioning of the entire speaker. A passive radiator 30 is also fixedly installed on the lower shell 14.

[0035] See Figure 1 , 4The structure of the upper shell 12 is described below. The back side (lower side) of the recess 115 of the upper shell 12 has an upper shell tube 112 communicating with the liquid inlet 110, through which liquid is introduced into the liquid inlet 110. Furthermore, a plurality of support legs 114 are provided around the liquid outlet 111 on the lower end face of the upper shell 11. There are at least two or more support legs 114, evenly or unevenly distributed along the circumference of the liquid outlet 111. In addition, a connecting ring 113 is provided to enhance the connection strength of the support legs 114. The connecting ring 113 is disposed within the cavity formed by the support legs 114 and is simultaneously connected to the support legs 114.

[0036] See Figure 3 , 5 The LED lamp assembly in this embodiment will be described as shown. See also... Figure 3 As shown, the LED light assembly includes an LED light 86 and a lamp housing 85 sleeved on the outside of the LED light 86. The LED light assembly is electrically connected to the pump body 83 via a wire 84, meaning the pump body 83 supplies power to the LED light assembly. In this embodiment, the lamp housing 85 is fixedly disposed in the space formed by the plurality of support legs 114, allowing the LED light to be inserted into the liquid outlet 111 or positioned directly below the liquid outlet 111. Because the LED light assembly is positioned at the bottom or below the liquid outlet 111, the LED light assembly is illuminated near the liquid outlet 111, producing a light color effect and enhancing visual appeal.

[0037] See Figure 1 , 3 As shown in Figure -4, the operating principle of the pump body 83 is explained. The outlet pipe 831 of the pump body 83 is inserted into and connected to the connector 71. The connector 71 is connected to the upper shell connector 112 through the fitting 60. See also... Figure 1 As shown, the opening direction of the inlet hole 110 is parallel or substantially parallel to the radial direction of the upper shell 11. When the pump body 83 is running, the damping fluid is drawn into the pump body 83 from its inlet, and after passing through the outlet pipe 831, connector 71, and fitting 60, it enters the upper shell fitting 112 and is pumped from the inlet hole 110 into the recess 115. Since the opening direction of the inlet hole 110 is parallel or substantially parallel to the radial direction of the upper shell 11, the damping fluid flowing out of the inlet hole 110 will be injected into the recess 115 in a direction parallel to the radial direction (tangential direction), forming a water vortex effect, which increases the water flow speed, accelerates water evaporation, and improves the humidification effect. The damping fluid entering the recess 115 will flow out from the outlet hole 111 located near or at the bottom of the recess 115 under the action of gravity and return to the middle shell receiving space 121, thereby realizing the circulation of the damping fluid in the middle shell receiving space 121 and the recess 115.

[0038] See Figure 3 , 6 The structure housed inside the main shell 13 is described below. See also... Figure 3 As shown, for ease of installation and assembly, the main housing 13 in this embodiment includes a main housing body 131, a side cover 132, and a protective filter 133. See also Figure 6 As shown, the upper end of the main housing 131 has a top plate 1313 forming an end face. The side wall of the main housing 131 has a notch, which mates with the side cover 132 to form a complete cylindrical surface. Inside the main housing 13, a partition 1311 is provided, dividing the inner cavity of the main housing 13 into two sub-cavities: a circuit board accommodating space and a speaker unit accommodating space. The left side of the partition 1311 is the circuit board accommodating space, where the drive circuit board 40 is located and electrically connected to the power interface 1312. The right side of the partition 1311 is the speaker assembly accommodating space, where the speaker unit 20 is located and electrically connected to the drive circuit board 40. The speaker unit 20 is fixed to the top plate 1313 of the main housing 13. To transmit the sound from the speaker unit 20 from the inner cavity of the main housing 13 to the outside, the side cover 132 has openings that directly face and correspond to the speaker units 20. In addition, to seal the opening and reduce the entry of dust and other foreign objects into the inner cavity of the main shell 13, a protective filter 133 covering the opening is connected to the side cover 132. Furthermore, passive radiators 30 are positioned directly below the speaker units 20, with the number corresponding to the number of speaker units 20. The passive radiators 30 enhance the bass effect of the sound. The drive circuit board 40 is fixedly mounted on the lower end of the top plate 1313 of the middle shell 13 via a connecting rod, maintaining a certain distance from the top plate 1313. A wireless charging coil, fixed to the top plate 1313, is positioned directly above the drive circuit board 40. In this embodiment, a wireless induction coil is provided at the bottom of the pump body 83, and a wireless charging coil wirelessly connected to it is provided on the upper side of the drive circuit board 40. The wireless charging coil and the wireless induction coil cooperate to achieve an electrical connection between the pump body and the drive circuit board 40.

[0039] The present invention utilizes the damping effect of the damping fluid stored in the recess 115 in the upper shell 11 and the middle shell cavity 121 in the middle shell 12, as well as the weight of the damping fluid itself, to reduce the vibration of the outer shell assembly 10, thereby reducing the sound distortion of the speaker 100 and improving the sound quality of the speaker 100.

[0040] 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 within the protection scope of the present invention.
