Description

Technical Field

[0001] The invention relates to the technical field of audio processing, in particular to a Bluetooth speaker with a hidden interface protection mechanism. Background Art

[0002] A Bluetooth speaker is an audio device that uses Bluetooth technology for audio transmission. It is usually used to play music and other audio content. They usually have built-in speakers, amplifiers and Bluetooth receivers and can be connected to various audio source devices via Bluetooth, such as smartphones, tablets, laptops, etc., to achieve wireless audio transmission and playback.

[0003] The interfaces of existing Bluetooth speakers are divided into two types: with covers and without covers. The interfaces of Bluetooth speakers with covers are only used to prevent dust and water when in use. When the extended wire is accidentally pulled, the cover of the interface cannot protect the wire from being stably connected to the interface. The wire will directly break away from the interface and disconnect, interrupting the playback of the Bluetooth speaker.

[0004] The existing wires used for audio data transmission have different diameters. After the cover is closed, it is impossible to limit and fix the wires of different thicknesses. If the wires shake or rub when plugged into the interface, the data transmission between the wires and the interface will be unstable. At the same time, the wires and the interface will be worn due to mutual friction, which will cause the problem of being unable to be plugged in tightly during later use.

[0005] The sound unit inside the existing speakers is rigidly connected to the speakers. During the sound vibration process, the speaker shell will be driven to vibrate synchronously, causing noise to be generated due to the vibration of the shell when the speakers are playing, thereby reducing the sound quality of the speakers when playing. At the same time, accompanied by the vibration of the sound unit inside the shell, the larger the sound unit, the higher the vibration amplitude. The rigid shell will be displaced on the table due to the high-frequency vibration. If the user fails to discover the movement of the speaker in time, the speaker will fall and be damaged, affecting the later use effect and service life of the speaker.

[0006] To this end, a Bluetooth speaker with a hidden interface protection mechanism is proposed. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The first spring is squeezed by the first circular plate when sliding inside the first limiting sleeve. When squeezed, the first spring absorbs energy and shrinks elastically. The kinetic energy generated by the vibration of the speaker module can be buffered by the elastic shrinkage and rebound of the first spring, so as to avoid the hard contact between the speaker module and the sound housing when the speaker module vibrates, driving the sound housing to vibrate together, reducing the noise generated by the vibration of the sound housing and the speaker module. At the same time, it also avoids the vibration of the sound housing and the speaker module together, preventing the internal parts of the sound housing from loosening and falling off due to high-frequency vibration during use, and preventing the internal parts of the sound housing from loosening and vibrating with the speaker module to generate noise. At the same time, the connection between the speaker module and the sound housing is buffered by the first spring and the second spring. When the sound housing falls or collides, the speaker module can avoid the direct transmission of the force of the sound housing to the speaker module through the buffering of the first spring and the second spring. The first limiting sleeve is covered on the outside of the first spring to avoid the sound waves of the speaker module being reflected by the first spring and being too dispersed when the speaker module plays, thereby improving the integrity of the sound when it propagates from the inside of the sound housing through the mesh plate to the outside;

[0017] 2. The vibration of the sound collecting plate drives the pressure rod to slide inside the round rod, so that the pressure rod will squeeze the transfer support downward during the downward movement. During the downward movement of the transfer support, the first clamping rod slides horizontally inside the round rod, and the connecting rod rotates around the rotation connection with the transfer support, so that the first clamping rod is pulled out of the slot through the rotation of the connecting rod, so that the first clamping rod no longer limits the movement of the round rod through the slot. Under the influence of the elastic extension of the fifth spring, the suction cup will quickly drop and be adsorbed on the table, thereby fixing the speaker shell on the table to avoid the horn When the speaker module plays loud sound, the sound housing resonates, causing the sound housing to shift and fall on the table. When the volume inside the sound housing is high, the sound collecting board vibrates, causing the suction cup to adsorb to the table to fix the sound housing. Compared with the prior art, the device always remains fixed to the table during use. This device controls the adsorption of the suction cup by the vibration of the sound collecting board, which can make the sound housing more convenient and avoid the problem that the user needs to repeatedly pull the suction cup to move the sound housing when the device plays at a low volume. ;

[0018] Among them, the wave-shaped design on the upper surface of the sound collecting plate can increase the strength and stability of the sound collecting plate structure. The wave-shaped structure can disperse stress, making the sound collecting plate more durable and stable. The wave-shaped design can also enable the sound collecting plate to absorb the sound waves inside the sound shell more fully, convert the sound waves inside the sound shell into kinetic energy in time and act on the stability of the sound shell, thereby improving the timeliness of the suction cup's stability on the sound shell.

[0019] 3. After the wire is inserted into the expansion interface, the torsion of the torsion spring is released to close the cover. The clamping of the wire by the pressure plate inside the cover and the force applied by the pressure plate to the wire moving toward the expansion interface as the cover rotates prevent the wire interface from shaking after the cover is closed, thereby reducing the wear caused by friction between the wire and the expansion interface during use and increasing the service life of the wire. After the cover is closed, the wire can always be pushed into the expansion interface by the cover, so that the wire is always tightly plugged into the expansion interface, avoiding the loosening of the connection between the wire and the expansion interface due to the vibration of the sound housing, thereby improving the stability of data transmission;

[0020] The button is pushed toward the inside of the dial block, so that the inclined plate squeezes and slides the metal plate, and the second clamping rod is disengaged from the clamping state with the tooth groove, so that the dial block can slide in the tooth groove toward the direction close to the sound housing, so that the rotating shaft rotates by pulling the pull rope, and drives the cover to open. Affected by the shape of the clamping teeth in the tooth groove, the second clamping rod moves in the tooth groove away from the sound housing without the staff pressing the button, so that the cover can be actively closed when the user does not operate it, thereby preventing the expansion interface from falling into dust, and reducing the influence of dust and foreign debris falling into the expansion interface on signal transmission. The dial block can be slid to open the cover only after the staff presses the button, which can effectively prevent the cover from being directly opened when the wire is pulled by the outside world, thereby improving the stability of the connection between the expansion interface and the wire, and at the same time avoiding the wear of the expansion interface caused by the wire being pulled by the outside world, thereby improving the service life of the sound housing;

[0021] 4. The matching semicircular plates and semicircular grooves set on the side where the two cover plates are close to each other are interlocked, so that the upper and lower cover plates can be more stable after closing, and the displacement of a single cover plate when subjected to lateral thrust during use is avoided, which causes the circular holes on the two cover plates to be misaligned, causing wear and damage to the wires passing through the circular holes. At the same time, it is avoided that excessive force is applied to the rotating connection between the single cover plate and the protective shell when the single cover plate moves laterally, causing damage and falling off. The synchronous movement of the two cover plates can effectively improve the bearing capacity of the cover plates when facing lateral thrust. The design of the semicircular plates and semicircular grooves matched with the two cover plates can increase the structural stability of the two cover plates. When closed, the buckling between the semicircular plates and the semicircular grooves provides additional support and connection, making the cover plates more stable and less likely to deform when subjected to external force. The buckling of the semicircular plates and the semicircular grooves can effectively prevent the two cover plates from loosening during vibration or movement. The buckling design makes the cover plates tighter in the closed state, reducing the possibility of loosening and damage due to external influences. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Working principle:

[0047] In the initial state, the staff places the audio shell 11 on the table, starts the internal power of the audio shell 11, wirelessly connects the mobile phone to the audio shell 11 via Bluetooth, and transmits Bluetooth signals between the mobile phone and the audio shell 11 to make the speaker module 13 inside the audio shell 11 vibrate and make a sound, and the fifth spring 314 is in an elastically contracted state.

[0048] During operation, since the speaker module 13 transmits sound through the air via the high-frequency vibration of the internal speaker when in use, the speaker module 13 will vibrate up and down at a high frequency when making a sound.

[0049] The vibration of the sound housing 11 during use is reduced by the buffer component 2:

[0050] like Figures 1 to 4As shown, when the speaker module 13 moves upward, the upward movement of the speaker module 13 will drive the second bracket 27 fixedly connected to the outer walls on both sides thereof to move upward together. In the process of the second bracket 27 moving upward, the second T-shaped shaft 28 will be driven to move upward together. At this time, because the first slide bar 24 and the first circular plate 25 are both limitedly slid inside the first limiting sleeve 23, and the first T-shaped shaft 22 fixedly connected to the outer wall of the first limiting sleeve 23 rotates on the first bracket 21, when the second bracket 27 drives the second T-shaped shaft 28 to move upward together, the second T-shaped shaft 28 is affected by the sliding of the first slide bar 24 inside the first limiting sleeve 23 and rotates with the second bracket 27. As the second T-shaped shaft 28 continues to move upward, the second T-shaped shaft 28 will drive the first slide bar 24 to move inside the first limiting sleeve 23. 3 slides in the direction away from the first T-shaped shaft 22, the first slide bar 24 moves to drive the first circular plate 25 to slide together in the first limiting sleeve 23, and the first circular plate 25 slides in the direction away from the first T-shaped shaft 22, which will cause the first spring 26 to be squeezed and elastically contracted. During the elastic contraction process, the first spring 26 will reduce the vibration of the speaker module 13 on the sound housing 11 when the speaker module 13 moves upward. When the speaker module 13 moves upward, it will drive the second limiting sleeve 211 to move upward together. At this time, the second spring 210 fixed between the lower surface of the speaker module 13 and the second slide bar 29 is stretched and elastically stretched. During the stretching process, the second spring 210 will absorb the potential energy of the speaker module 13 moving upward, thereby reducing the distance the speaker module 13 moves upward.

[0051] When the speaker module 13 moves downward, the first spring 26 will elastically contract as the speaker module 13 drives the first circular plate 25 through the second bracket 27, the second T-shaped shaft 28 and the first slide bar 24, and the second spring 210 will elastically contract as the distance between the speaker module 13 and the second slide bar 29 is reduced. Therefore, the elastic expansion and contraction of the first spring 26 and the second spring 210 absorbs energy when the speaker module 13 vibrates, thereby preventing the speaker module 13 from directly contacting the sound housing 11 when vibrating, causing resonance between the sound housing 11 and the speaker module 13 and affecting the sound effect.

[0052] The auxiliary support assembly 3 is used to stabilize the sound housing 11 during playback:

[0053] like Figure 5 and Figure 6As shown, when the speaker module 13 vibrates and makes a sound, the vibration of the speaker module 13 drives the air in the inner cavity of the sound housing 11 to vibrate together, so that the sound collecting plate 32 slidably connected to the bottom of the inner cavity of the sound housing 11 vibrates up and down, and the up and down vibration of the sound collecting plate 32 drives the third slide bar 31 to slide up and down at the bottom of the sound housing 11. The third spring 33 is affected by the up and down movement of the sound collecting plate 32 and continuously expands and contracts. The amplitude of the up and down vibration of the sound collecting plate 32 is affected by the vibration generated by the different volumes when the speaker module 13 plays the sound. As the volume of the speaker module 13 increases, the vibration amplitude of the sound collecting plate 32 also increases accordingly. The amplitude of the air vibration inside the sound housing 11 increases, and the sound housing 11 as a whole vibrates, so that the sound housing 11 is displaced due to the vibration, and finally falls off the table. At this time, when the sound collecting plate 32 with a large vibration moves downward, it will cause downward compression on the pressure rod 35, causing the pressure rod 35 to slide downward inside the round rod 34. At this time, the fourth spring 36 is squeezed and elastically contracts. After the pressure rod 35 slides downward inside the round rod 34, its lower end will cause downward compression on the transfer support 39. The downward movement of the transfer support 39 will drive the fourth slide bar 38 to move in the third limit sleeve 37. The inner part of the third limiting sleeve 37 slides downward, causing the airtight cavity inside the third limiting sleeve 37 to shrink and form high pressure. During the downward movement of the transfer support 39, the first clamping rod 311 slides toward the inside of the round rod 34 through the rotation of the connecting rod 310, so that the first clamping rod 311 is no longer clamped in the clamping groove 312 of the sound housing 11. When the first clamping rod 311 is no longer clamped in the clamping groove 312, the round rod 34 is no longer affected by the limiting effect of the first clamping rod 311 and the clamping groove 312 and can move vertically. At this time, the contracted fifth spring 314 elastically stretches, and the fifth spring 314 passes through the second circular plate 31 The rod 34 and the suction cup 315 are pushed to move downward as a whole. After the suction cup 315 moves downward, it contacts the table and is deformed by the compression of the fifth spring 314. As the suction cup 315 is compressed by the table, the air inside the suction cup 315 is discharged to the outside through the one-way valve 316. When the fifth spring 314 is stretched, the air inside the suction cup 315 is no longer discharged to the outside. At this time, the one-way valve 316 resumes the closed state of the suction cup 315. Through the adsorption of the two suction cups 315 on the table, the sound housing 11 will not be displaced or fall due to its own vibration when the volume is high.

[0054] Prevent external wiring materials from loosening through the interface protection component 4:

[0055] like Figures 7 to 10As shown, when the expansion interface 15 needs to insert the expansion wire, the user first presses the button 48 toward the inside of the dial block 47. When the button 48 moves toward the inside of the dial block 47, the sixth spring 49 is squeezed and elastically contracts, and the inclined plate 410 fixedly connected to the button 48 is affected by the movement of the button 48 and moves toward the direction close to the metal plate 412. In the process of the inclined plate 410 moving toward the inside of the dial block 47, the inclined surface of the inclined plate 410 away from the button 48 pushes the metal plate 412 toward the inside of the dial block 47. In the process of the movement of the metal plate 412, the metal plate 412 can only move in the vertical direction due to the limited sliding of the second clamping rod 411 inside the dial block 47. As the metal plate 412 drives the second clamping rod 411 to move, the metal plate 412 moves in the vertical direction. 1 moves toward the inside of the shift block 47, and the end of the second clamping rod 411 located on the outside of the shift block 47 is no longer clamped on the tooth groove 46, so that the shift block 47 can slide horizontally in the tooth groove 46 toward the direction close to the sound housing 11. When the user slides the shift block 47 in the tooth groove 46 toward the direction close to the sound housing 11, the distance between the shift block 47 and the rotating shaft 44 is extended, so that the pull rope 413 originally wound on the surface of the rotating shaft 44 is straightened. The pull rope 413 drives the rotating shaft 44 to rotate during the straightening process, so that the two opposite cover plates 42 are flipped open. During the rotation of the rotating shaft 44, the torsion spring 45 generates torque due to the rotation. When the two cover plates 42 are flipped open, the user inserts the required expansion wire into the expansion interface 15;

[0056] After the expansion wire is plugged in, the user stops pressing the button 48 toward the inside of the dial block 47. At this time, the button 48 is elastically stretched by the sixth spring 49 and returns to its initial state. After the two opposing metal plates 412 are no longer squeezed by the inclined plate 410, the two second clamping rods 411 slide relatively inside the dial block 47 due to the magnetic repulsion effect of the same magnetic poles of the magnetic coatings on their opposing surfaces. After sliding, the second clamping rods 411 are re-engaged in the inside of the tooth groove 46. Then the user stops pushing the dial block 47 toward the direction of the audio housing 11, and the torsion force of the torsion spring 45 is released. The torsion release of the torsion spring 45 drives the rotating shaft 44 to rotate. After the rotating shaft 44 rotates, the pull rope 413 is wrapped around its outer wall and pulls the dial block 47 to slide in the tooth groove 46 to the side away from the audio housing 11. During the movement of the dial block 47 in the tooth groove 46 in the direction away from the sound housing 11, because the contact surface between the tooth groove 46 and the second clamping rod 411 is an inclined surface, the second clamping rod 411 can be squeezed by the inclined surface inside the tooth groove 46 and slide into the dial block 47. When the cover 42 and the protective shell 41 are completely closed, the pull rope 413 no longer pulls the dial block 47 to slide. At this time, the second clamping rod 411 elastically stretches and is clamped in the tooth groove 46. Because the second clamping rod 411 moves in the tooth groove 46 in the direction close to the sound housing 11, the contact surface between the second clamping rod 411 and the tooth groove 46 is a vertical surface. Therefore, the dial block 47 cannot move in the direction close to the sound housing 11 when the button 48 is not pressed, so that the cover 42 cannot be opened when the user does not press the button 48.

[0057] When the cover 42 is flipped and closed, the pressure plate 414 inside the cover 42 will squeeze the wire. Through the flipping and squeezing of the upper and lower pressure plates 414 when they rotate, the wire will be squeezed by the pressure plate 414 after the cover 42 is closed and limited to be unable to move. At the same time, through the torsion rebound of the torsion spring 45, the pressure plate 414 has the force to move the wire toward the expansion interface 15 while clamping the wire, so that the wire is tightly plugged into the expansion interface 15. The excess wire will pass through the cover 42 through the circular hole 43, and the user will operate the transmission end.
