Description

Technical Field

[0001] The present invention relates to the field of Bluetooth speakers, and in particular to a Bluetooth speaker with shockproof and dustproof functions. Background Art

[0002] A Bluetooth speaker is a portable or fixed speaker device that uses Bluetooth wireless technology to transmit audio signals. It can connect wirelessly to a mobile phone or computer via Bluetooth, and then play the audio transmitted by the mobile phone or computer through its built-in speakers.

[0003] However, when ordinary Bluetooth speakers are used in daily life, their built-in speakers usually have a woofer to produce bass. When the woofer produces bass, the entire speaker will vibrate, and resonance will occur when the speaker contacts the ground or wall. The resonance will not only reduce the sound quality but may also cause damage to the internal structure of the speaker. In addition, people often take Bluetooth speakers outdoors to use them. In some dusty outdoor scenes, dust may enter the speaker, and the speaker needs to be disassembled to clean the dust or water, which will affect the pronunciation of the speaker, and thus affect its performance and service life.

[0004] For example, Chinese patent publication number CN217335803U discloses a Bluetooth audio housing with a shockproof and dustproof structure.

[0005] It includes side panels, a bottom panel and a top panel. The side panels are provided with dustproof mechanisms for filtering and adsorbing dust. The bottom panel and the top panel are provided with shockproof mechanisms for buffering impact force. The shockproof mechanisms include shockproof plates slidably connected to the four corners of the bottom panel and the top panel. A plurality of shock-absorbing springs are fixedly connected to the shockproof plates. The other end of the shock-absorbing spring is fixedly connected to the shock-absorbing plate, which can adsorb and filter dust in the flowing airflow for multiple times, so that dust is not easily adsorbed or dropped on the speaker, thereby avoiding clogging of the speaker, effectively protecting the internal structure of the speaker box, and avoiding affecting the sound effect.

[0006] However, the above-mentioned Bluetooth speakers still have some shortcomings in actual use:

[0007] 1. The above-mentioned speakers are only provided with a shockproof mechanism at the bottom, that is, only the bottom of the speakers can be shockproofed and buffered. If the sides or the front and back of the speakers fall on the ground, the speaker body will also be broken without the protection of the shockproof mechanism. Moreover, the above-mentioned device can only be placed on the ground and cannot be hung on the wall, so the applicability is low.

[0008] 2. Although the above-mentioned audio device can reduce the dust from entering the interior of the audio device by means of fan blowing, that is, if a speaker is installed inside the audio device, the sound produced by the speaker can only be transmitted to the outside through the gap of the fan opening. The fan will generate noise during operation, affecting the sound quality of the speaker. Furthermore, if the above-mentioned device is not used for a long time, dust may still be attached to the outside of the fan, and the dust may enter the above-mentioned shell through the gap of the fan opening, and the above-mentioned audio structure domain cannot quickly clean the dust inside the audio device.

[0009] Therefore, based on the above-stated viewpoint, there is still room for improvement in existing audio systems. Summary of the invention

DETAILED DESCRIPTION

[0036] The following combination Figures 1 to 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0037] The embodiment of the present application discloses a Bluetooth speaker with shockproof and dustproof functions. It is explained that the Bluetooth speaker with shockproof and dustproof functions is mainly used in the process of protecting the speaker from shock and dust. In terms of technical effect, a buffer structure is provided on the outside of the speaker to achieve shockproof treatment of the speaker. Furthermore, the Bluetooth speaker with shockproof and dustproof functions can also wipe off the dust attached to the outside of the speaker and discharge the dust inside the speaker out of the speaker, thereby further improving the applicability of the present invention.

[0038] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a rectangular box 1, a partition plate 10, a loudspeaker 11 and a barrier unit 2. Two circular grooves of inconsistent sizes and distributed up and down are provided at one end of the rectangular box 1. A partition plate 10 is provided on the inner wall of the rectangular box 1. Two circular grooves corresponding to the circular grooves are provided on the partition plate 10. Two loudspeakers 11 of inconsistent sizes are respectively installed in the circular grooves. The partition plate 10 fixes the loudspeaker 11 through the circular grooves, and the circular grooves are connected to the pressure edge on the outside of the loudspeaker 11, that is, the loudspeaker 11 vibrates to transmit sound, and the paper cone located in the pressure edge will not be limited, so the loudspeaker 11 can make sound normally, and the two loudspeakers 11 of different sizes can respectively emit high-frequency sound and low-frequency sound. The sounds emitted by the two loudspeakers 11 can be transmitted to the outside of the rectangular box 1 from the corresponding circular grooves.

[0039] A barrier unit 2 for blocking dust from entering the rectangular box 1 is arranged in the circular groove, and the barrier unit 2 is used to prevent external dust from entering the rectangular box 1 through the circular groove.

[0040] Continue to refer to Figure 2 and Figure 3 As shown, a barrier unit 2 is used to prevent dust from entering the rectangular box 1; specifically, the barrier unit 2 includes a dust cover 1 20, a dust cover 21, a circular hole 22, a strip plate 23 and bristles 24, the dust cover 1 20 is arranged on the inner diameter of the circular groove, and a dust cover 21 corresponding to the dust cover 1 20 is also rotatably arranged in the circular groove, and the outer sides of the dust cover 1 20 and the dust cover 21 are both provided with circular holes 22 evenly distributed along the circumference of their extended surfaces, and the dust cover 21 can be rotated in the circular groove under the limitation of the circular groove, and the dust cover 1 21 can be rotated in the circular groove. 0 can block large particles of dust or debris in the external environment through the circular hole 22 on its outer side, preventing dust and particles from entering the rectangular box 1 through the circular groove and adhering to the paper cone of the speaker 11, resulting in inaccurate pronunciation due to excessive dust adhering to the outer side of the paper cone. The circular hole 22 on the dust cover 21 is used to allow the sound emitted by the corresponding speaker 11 to be transmitted to the outside of the rectangular box 1. The transmission order of the sound of the speaker 11 is to be transmitted to the outside of the rectangular box 1 through the circular holes 22 on the outer sides of the dust cover 21 and the dust cover 1 20.

[0041] A strip plate 23 is provided at one end of the dust cover 21 facing the dust cover 1 20, and bristles 24 corresponding to the circular holes 22 on the outside of the dust cover 1 20 are provided on one side of the strip plate 23. The dust cover 21 can drive the strip plate 23 to rotate synchronously, and the strip plate 23 can drive the bristles 24 to scrape the circular holes 22 on the outside of the dust cover 20 when rotating, so that the dust in the circular holes 22 on the outside of the dust cover 20 is brushed off by the bristles 24, and the dust and particulate matter will be pushed by the bristles 24 through the corresponding circular holes 22 to separate from the circular grooves and fall outside the rectangular box 1, that is, large particles are blocked by the circular holes 22 on the outside of the dust cover 1 20, and the circular holes 22 on the outside of the dust cover 21 are only used for sound transmission, so there is no need to clean them.

[0042] Reference Figure 4 and Figure 5 As shown, two support plates 30 corresponding to the circular grooves are arranged on the inner wall of one side of the rectangular box 1, and a rotating unit 3 for driving the dust cover 21 to rotate is arranged on the support plate 30; specifically, the rotating unit 3 includes a support plate 30, a driven ring 31, a support shaft 32, a driving ring 33, a wiping assembly 4 and a driving motor 34, the driven ring 31 is arranged in the middle of the dust cover 21, and the driving ring 33 can drive the corresponding dust cover 21 to rotate when driven externally.

[0043] A support shaft 32 having one end passing through the driven ring 31 is provided on one side of the support plate 30, and a drive ring 33 is rotatably provided on the outer diameter of one side of the support shaft 32. The support shaft 32 is fixedly limited inside the rectangular box 1 by the support plate 30, and the drive ring 33 can rotate on the outer side of the support shaft 32.

[0044] A wiping component 4 for wiping the speaker 11 is provided on the driving ring 33. When the driving ring 33 rotates, it can synchronously drive the corresponding wiping component 4 to wipe the outer side of the paper cone inside the corresponding speaker 11. Since the circular hole 22 on the outer side of the dust cover 20 can only block dust particles of a certain size, some very fine particles can still enter the rectangular box 1 through the circular holes 22 on the dust cover 1 20 and the dust cover 2 21 and adhere to the paper cone of the speaker 11. Therefore, the dust on the outer side of the corresponding paper cone can be wiped off by the wiping component 4 at this time.

[0045] The driving ring 33 and the driven ring 31 are connected by gear meshing, and the upper and lower driving rings 33 are connected by belt transmission. A driving motor 34 is also provided on one side of the partition plate 10 through a motor seat, and the driving shaft of the driving motor 34 is connected to the driving ring 33 at the upper end by belt transmission. The partition plate 10 supports the driving motor 34 through the motor seat. The driving motor 34 can drive the upper driving ring 33 to rotate through the belt transmission, and the upper driving ring 33 can drive the lower driving ring 33 to rotate synchronously through the belt transmission, so that the wiping components 4 corresponding to the two speakers 11 can wipe the corresponding speakers 11, and the driving ring 33 can also drive the corresponding driven ring 31 to rotate through gear transmission when rotating, so that the driven ring 31 has a driving force to drive the corresponding dust cover 21 to rotate.

[0046] Continue to refer to Figure 4 and Figure 6 As shown, the wiping assembly 4 is used to wipe the speaker 11; specifically, the wiping assembly 4 includes a strip arc plate 40, a swinging plate 41, an L-shaped plate 42 and a wiping block 43. The strip arc plate 40 is arranged on one side of the driving ring 33 and extends toward the inner diameter of the speaker 11. The end of the strip arc plate 40 away from the driving ring 33 is hinged with a swinging plate 41 through a torsion spring (not shown in the figure). When the driving ring 33 rotates, it can drive the corresponding strip arc plate 40 to rotate synchronously along its axis. When the strip arc plate 40 rotates, it can drive the swinging plate 41 to rotate synchronously. The swinging plate 41 can also swing toward the speaker 11 or away from the speaker 11 along its hinge point at the end of the strip arc plate 40. Due to the force of the torsion spring, in the initial state, the swinging plate 41 swings toward the speaker 11.

[0047] An L-shaped plate 42 is provided on the partition plate 10, and one end of the L-shaped plate 42 is in contact with one side of the swing plate 41. A wiping block 43 corresponding to the inner diameter of the paper cone of the speaker 11 is provided on one side of the swing plate 41. The swing plate 41 can be driven by the strip arc plate 40 to rotate, thereby driving the wiping block 43 to wipe the outer side of the paper cone on the speaker 11, and wipe off the dust attached to the outer side of the paper cone.

[0048] A curvature groove (not shown in the figure) is provided on one side of the swing plate 41, that is, when the swing plate 41 rotates to be in close contact with one side of the L-shaped plate 42, the curvature groove on the swing plate 41 is in close contact with one end of the L-shaped plate 42, driving the swing plate 41 to swing in the opposite direction, driving the corresponding wiping block 43 to no longer be in close contact with the paper cone on the speaker 11. The purpose of doing this is that when the paper cone in the speaker 11 vibrates to produce sound, if the wiping block 43 is still in contact with the outside of the paper cone, the paper cone will not be able to vibrate normally, that is, it will not be able to produce normal sound. Therefore, after the swing plate 41 drives the wiping block 43 to wipe the paper cone once, it can be driven by the L-shaped plate 42 to drive the wiping block 43 to no longer be in contact with the paper cone.

[0049] Continue to refer to Figure 1 and Figure 7 As shown, a shock absorbing unit 5 for shock absorption is provided at the bottom of the rectangular box 1; specifically, the shock absorbing unit 5 includes a support column 50, a sleeve 51, an electromagnet 52, a reset spring 53, a circular plate 54 and a friction pad 55. Several support columns 50 arranged in a rectangular shape are provided at the bottom of the rectangular box 1. A sleeve 51 is slidably provided on the outer side of the support column 50. The rectangular box 1 can slide up and down in the corresponding sleeve 51 through the support column 50.

[0050] Two repelling annular electromagnets 52 are disposed on the inner wall of the sleeve 51 and the lower end of the support column 50. When the electromagnets 52 are energized, the two electromagnets 52 are converted into a repelling state.

[0051] A reset spring 53 is connected between the lower end of the support column 50 and the inner wall of the sleeve 51. In the initial state, the reset spring 53 can pull the sleeve 51 at the lower end to fit tightly against the support column 50. A circular plate 54 is provided at the lower end of the sleeve 51, and a friction pad 55 is provided at the lower end of the circular plate 54. The rectangular box 1 as a whole drives the support column 50 to fit tightly against the bottom of the sleeve 51, and contacts the ground through the sleeve 51 and the circular plate 54, thereby indirectly supporting the rectangular box 1. The friction pad 55 can increase the friction between the circular plate 54 and the ground to avoid slipping. The reset spring 53 is used to ensure that the sleeve 51 can still fit tightly against the bottom of the support column 50 when the rectangular box 1 is picked up.

[0052] When shock absorption is required, the electromagnet 52 is energized. At this time, the repulsive force of the two corresponding electromagnets 52 is greater than the pulling force of the reset spring 53 and greater than the weight of the speaker. Therefore, the speaker can be lifted up as a whole. In this way, when the bottom of the speaker falls, the support column 50 slides up and down in the sleeve 51 to offset the force of contact with the ground. When the speaker plays music, the suspended support column 50 and the sleeve 51 reduce the contact area, indirectly reducing the contact with the ground, so that the speaker 11 reduces the vibration force transmitted to the ground when emitting bass, thereby improving the playback quality and effectively avoiding the damage to the structure caused by resonance between the speaker and the ground.

[0053] Reference Figure 8 As shown, the rectangular box 1 is also provided with a buffer unit 6 for preventing falling buffer around it; specifically, the buffer unit 6 includes an arc block 60, an arc groove 61, a push spring rod 62, an arc plate 63, a rubber pad 64, a sliding groove 65, a buffer plate 66 and a foam plate 67, four arc blocks 60 are arranged at the four corners of the rectangular box 1, an arc groove 61 is opened inside the arc block 60, a push spring rod 62 is arranged on the inner wall of the arc groove 61, and a push end of the push spring rod 62 is provided with an arc plate 63 located in the arc groove 61, and the arc plate 63 can slide back and forth in the arc groove 61, and the push spring rod 62 can push the arc plate 63 to move toward the outside of the arc block 60 in the initial state.

[0054] A rubber pad 64 is attached to the outside of the arc plate 63. When the corner of the speaker falls to the ground, the rubber pad 64 will first contact the ground to protect the arc plate 63. Then the arc plate 63 gives a reverse force to the pushing spring rod 62 and moves synchronously to the inside of the arc groove 61, which provides a buffering protection for the speaker, reduces the force of the fall and reduces damage.

[0055] Except for the two arc blocks 60 at the bottom, the other two arc blocks 60 are each provided with a sliding groove 65 at the opposite ends, and a buffer plate 66 is slidably arranged in the corresponding arc groove 61, and a push spring (not shown in the figure) is arranged between the buffer plate 66 and the inner wall of the sliding groove 65, and a foam plate 67 is arranged at the end of the buffer plate 66 away from the rectangular box 1, and a rubber pad 64 is also attached to the end of the foam plate 67 away from the buffer plate 66. The buffer plate 66 can reciprocate in the sliding groove 65. After the outside of the speaker falls to the ground, some protrusions on the ground will first contact with the rubber pad 64, and push the buffer plate 66 to move toward the direction of the rectangular box 1 through the rubber pad 64 and the buffer plate 66, and the buffer plate 66 squeezes the push spring, and the falling force on the speaker is reduced by the descent of the buffer plate 66 and the buffering of the rubber pad 64 and the foam plate 67.

[0056] Continue to refer to Figure 1 and Fig. 9 As shown, a buffer component 7 for buffering and protecting the rear side of the rectangular box 1 is also provided on one side of the rectangular box 1; specifically, the buffer component 7 includes a spring push rod 70, a rectangular plate 71, a guard plate 72, a sound outlet groove 73 and a magnetic plate 74. The structural groove is opened at the four corners of the rear side of the rectangular box 1. A spring push rod 70 is provided on the inner wall of the structural groove. The telescopic end of the spring push rod 70 passes through the structural groove and is jointly provided with a rectangular plate 71. In the initial state, the spring push rod 70 pushes the rectangular plate 71 not to be tightly attached to the outer side of the rectangular box 1. After the rear side of the rectangular box 1 falls to the ground, the rectangular plate 71 will first contact the ground and squeeze the telescopic end of the spring push rod 70 to move toward the direction of the structural groove, thereby playing a buffering role for the speaker.

[0057] A guard plate 72 is installed at the front end of the rectangular box 1. Two sound outlet grooves 73 corresponding to the circular grooves are formed on the guard plate 72. The guard plate 72 can protect the front end of the speaker from having a certain buffering force after it contacts the ground. The sound outlet grooves 73 are used to avoid blocking the circular grooves, so that the sound emitted by the speaker 11 can be transmitted to the outside of the rectangular box 1.

[0058] The rectangular plate 71 is provided with two symmetrically distributed rectangular grooves, in which magnetic plates 74 are installed. The speaker can be attached to an iron door or fence through the magnetic plates 74, further improving the applicability of the present invention.

[0059] Example 2: Reference Fig.10 As shown, on the basis of the first embodiment, in order to discharge the dust cleaned from the speaker 11 out of the rectangular box 1, a discharge component 8 is provided at the upper and lower ends of the rectangular box 1; specifically, the discharge component 8 includes a ventilation slot 80, a fan 81, a filter plate 82, a discharge slot 83 and a rubber plug 84, the ventilation slot 80 is opened at the upper end of the rectangular box 1, a fan 81 is provided on the inner wall of the ventilation slot 80, a filter plate 82 is also provided on the inner wall of the ventilation slot 80, and many small holes are provided on the filter plate 82, the fan 81 can blow the wind through the ventilation slot 80 into the rectangular box 1, the small holes on the filter plate 82 can block the large particles from the outside from entering the rectangular box 1, and when the wiping component 4 tests the dust, the dust will fall into the rectangular box 1, and at this time the dust is blown to the bottom of the rectangular box 1 by wind.

[0060] A discharge groove 83 is also provided at the bottom of the rectangular box 1 , and a rubber plug 84 is inserted at the opening of the discharge groove 83 . When the rubber plug 84 is pulled out, the bottom of the discharge groove 83 is no longer blocked, so that dust can be discharged from the rectangular box 1 through the discharge groove 83 .

[0061] During operation: the first step is to place the speaker on the ground. At this time, the electromagnet 52 in the shock absorbing unit 5 is energized, so that the shock absorbing unit 5 can have a certain shock absorbing effect when the speaker plays music, and can also provide buffering protection for the bottom of the rectangular box 1 when the speaker falls from a high altitude.

[0062] Step 2: The barrier unit 2 can prevent large dust particles from the external environment from entering the rectangular box 1, and the rotating unit 3 can also drive the bristles 24 to remove particles in the circular hole 22 outside the dust cover 20.

[0063] Step 3: Furthermore, the rotating unit 3 can also drive the wiping component 4 to wipe the outside of the paper cone in the corresponding speaker 11, wipe off the small particles attached to the outside of the paper cone, and finally discharge the dust outside the rectangular box 1 through the discharge component 8.

[0064] Step 4: The buffer unit 6 can provide buffer protection for the four corners and the outer side of the rectangular box 1 to prevent the components inside the audio system from being damaged when the rectangular box 1 falls.

[0065] Step 5: The front and rear sides of the rectangular box 1 can be buffered and protected by the buffer component 7, and the speaker can be adsorbed on the iron product by the magnetic plate 75 in the buffer component 7, which further improves the applicability of the present invention.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
