Description

Technical Field

[0001] This utility model relates to the field of audio output accessories technology, and more specifically, to retractable and adjustable speaker cables. Background Technology

[0002] In the field of audio equipment, speaker cables, as the core transmission component connecting the sound source and the speaker, have significant flexibility and diversity in their application scenarios: they need to be suitable for close-range scenarios, such as a distance of 0.3-1 meter between desktop speakers and a computer, as well as for medium- and long-range deployment needs, such as a distance of 2-5 meters between the main speaker and the amplifier in a home theater, and a distance of 5-10 meters between devices during outdoor performances; for portable speakers, such as Bluetooth speakers for outdoor camping and monitor speakers for mobile performances, fixed-length cables will increase the overall "bulky" feel of the equipment, and are easy to get tangled with other items in the backpack, such as headphones and chargers, causing wear and tear on the insulation layer of the cable. Therefore, it is necessary to use extendable and adjustable speaker cables.

[0003] Existing retractable speaker cables suffer from repeated friction between the cable and the enclosure wall due to frequent extension and retraction, which can easily damage the cable sheath and reduce its shielding effect against external electromagnetic interference. This makes the speaker susceptible to external interference, resulting in noise or jarring sounds. To address these issues, we propose a retractable speaker cable. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a retractable and adjustable speaker cable to solve the problem that traditional speaker cables are easily damaged by repeated friction between the outer sheath and the storage compartment wall during use, thereby reducing the shielding effect against external electromagnetic interference and causing the speaker to produce noise or interference.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a retractable and adjustable speaker cable, including a storage component, a guide component, and an audio cable assembly; the storage component includes a storage compartment, cable inlet channels on the front and rear sides of the storage compartment, a groove on the inner wall of the cable inlet channel, a turntable on one side of the storage compartment, a winding roller inside the storage compartment and connected to the turntable at one end, a winding groove on the surface of the winding roller, and a threading hole on the surface of the winding roller and located inside the winding groove; the guide component includes a slider inside the cable inlet channel, pulleys on the top and bottom of the slider and connected to the groove, a first guide hole in the middle of the slider, and miniature ball bearings on the inner wall of the first guide; the audio cable assembly includes an audio cable body passing through the threading hole and wound around the surface of the winding roller, with connection ports at both ends of the audio cable body, and the connection ports extending through the first guide hole to the outside of the storage compartment;

[0006] When the turntable rotates, the winding roller rotates synchronously with the turntable, and the audio cable body winds along the spiral winding groove on the surface of the winding roller. The spiral winding makes the audio cable body evenly stressed in each turn, avoiding local bending. At the same time, during the winding and shrinking process of the audio cable body, the audio cable body moves from the middle to both ends of the winding roller. The slider and pulley assist the horizontal displacement of the audio cable body, and the miniature ball bearings inside the first guide hole assist the telescopic displacement of the audio cable body.

[0007] Preferably, a knob is provided on one side of the turntable, and the knob is arranged in a cross shape. A handle is provided at the bottom of the storage compartment, and the surface of the handle is provided with a rubber anti-slip sleeve.

[0008] Preferably, an arc-shaped support plate is provided at one end of the inlet channel near the winding roller, and the arc-shaped support plate is located inside the storage compartment, and the arc-shaped support plate is inclined in the opposite direction.

[0009] Preferably, a buffer spring is provided on the side of the slider near the winding roller, a buffer baffle is provided at one end of the buffer spring, a second guide hole is provided in the middle of the buffer baffle, a silicone gasket is provided on the inner side wall of the second guide hole, and a limiting baffle that cooperates with the buffer baffle is provided near the middle of the audio cable body.

[0010] Preferably, the winding groove is spirally arranged, and the width of the winding groove is the same as the diameter of the audio cable body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs a storage component, a guide component, and an audio cable component. When the turntable rotates, the winding roller rotates synchronously with the turntable, and the audio cable body winds along the spiral winding groove on the surface of the winding roller. The spiral winding ensures that the audio cable body is evenly stressed in each turn, avoiding local bending. At the same time, during the winding and shrinking process of the audio cable body, the audio cable body is displaced from the middle to both ends of the winding roller. The slider and pulley assist the horizontal displacement of the audio cable body, and the micro-balls inside the first guide hole assist the extension and retraction displacement of the audio cable body, transforming the sliding friction during the extension and retraction of the audio cable body into rolling friction, greatly reducing frictional resistance, making winding and unwinding smoother, and reducing wear on the surface of the audio cable body. The arc-shaped support plate design guides the audio cable body to a smooth transition, avoiding right-angle bending.

[0013] 2. This utility model also incorporates a storage component, a guide component, and an audio cable component. A buffer spring is provided on one side of the slider, and a buffer baffle is provided at one end of the buffer spring. At the same time, a limiting baffle that cooperates with the buffer baffle is provided near the middle of the audio cable body. When the audio cable body extends to a preset value, the limiting baffle contacts the buffer baffle, which can effectively absorb the instantaneous impact force when the audio cable body is extended or retracted, avoiding damage to the audio cable body due to sudden force and further extending its service life.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] This utility model relates to a retractable and adjustable speaker cable, comprising a storage component 1, a guide component 2, and an audio cable assembly 3. The storage component 1 includes a storage compartment 101, cable inlet channels 102 on the front and rear sides of the storage compartment 101, a groove 103 on the inner wall of the cable inlet channel 102, a turntable 105 rotatably connected to one side of the storage compartment 101, a winding roller 107 rotatably connected inside the storage compartment 101 and connected at one end to the turntable 105, a winding groove 108 on the surface of the winding roller 107, and a wire through hole 109 on the surface of the winding roller 107 and located inside the winding groove 108. The storage compartment 101 is used to accommodate the winding roller 107 and the guide component 3. The internal structure of component 2 protects internal components from external collisions and dust corrosion. The inlet channel 102 provides a passage for the audio cable body 301 to enter and exit the storage compartment 101, restricting the extension and retraction path of the audio cable body 301 and preventing disorderly shaking. The slide groove 103 provides a linear motion track for the slider 201, ensuring that the slider 201 slides smoothly along the direction of the inlet channel 102 and preventing the audio cable body 301 from getting stuck or experiencing uneven force due to slider 201 deviation. The turntable 105 drives the winding roller 107 to rotate synchronously, realizing the winding / unwinding of the audio cable. The winding roller 107 serves as the supporting base of the winding groove 108, which is used for... The audio cable body 301 is forced to align along a fixed trajectory to prevent overlap, tangling, or excessive compression during winding. The threading hole 109 ensures that the audio cable body 301 winds symmetrically from the threading hole 109 towards both ends during winding. The guide assembly 2 includes a slider 201 slidably connected inside the cable inlet channel 102, a pulley 202 rotatably connected to the top and bottom of the slider 201 and connected to the slide groove 103, a first guide hole 203 opened in the middle of the slider 201, and a miniature ball bearing 204 rotatably connected to the inner sidewall of the first guide. The slider 201 moves synchronously with the extension and retraction of the audio cable body 301, passing through the first guide hole 203. The lateral offset of the audio cable body 301 is limited, and the linear movement of the audio cable body 301 is maintained. The pulley 202 is used to convert the sliding friction between the slider 201 and the groove 103 into rolling friction, reduce the moving resistance of the slider 201, make the audio cable body 301 retract and extend more smoothly, and reduce component wear. The first guide hole 203 provides precise guidance for the audio cable body 301, avoiding direct friction between the audio cable body 301 and the inner wall of the inlet channel 102. The micro ball 204 contacts the surface of the audio cable body 301, converting the sliding friction of the audio cable body 301 during extension and retraction into rolling friction, greatly reducing the coefficient of friction and reducing the wear of the insulation layer of the audio cable body 301.The audio cable assembly 3 includes an audio cable body 301 that passes through a wire hole 109 and is wound around the surface of a winding roller 107. Both ends of the audio cable body 301 are fixedly connected to connection ports 302, which extend through a first guide hole 203 to the outside of the storage compartment 101. Multiple strands of oxygen-free copper wire inside the audio cable body 301 are responsible for audio signal transmission. An outer TPE insulation layer and double-layer shielding ensure signal stability and reduce electromagnetic interference. The connection ports 302 use gold-plated phosphor bronze contacts to reduce contact resistance and ensure low-loss audio signal transmission. This invention, through the design of the storage assembly 1, guide assembly 2, and audio cable assembly 3, ensures that when the turntable 105 is rotated, the winding roller 107 follows the turntable 105. 5. The audio cable body 301 rotates synchronously and winds along the spiral winding groove 108 on the surface of the winding roller 107. This spiral winding ensures even force distribution on each turn of the audio cable body 301, preventing localized bending. Simultaneously, during the winding and retraction process, the audio cable body 301 shifts from the middle to both ends of the winding roller 107. The slider 201 and pulley 202 assist in the horizontal displacement of the audio cable body 301, while the miniature ball bearings 204 inside the first guide hole 203 assist in the extension and retraction of the audio cable body 301. This transforms the sliding friction during extension and retraction into rolling friction, significantly reducing frictional resistance and making winding and unwinding smoother, while also reducing wear on the surface of the audio cable body 301.

[0025] Specifically, a knob 106 is fixedly connected to one side of the turntable 105, and the knob 106 is arranged in a cross shape. The cross-shaped knob 106 increases the force application area of ​​the hand, reduces the difficulty of rotation operation, and improves the user's ease of operation. A handle 1010 is fixedly connected to the bottom of the storage compartment 101, and a rubber anti-slip sleeve is glued to the surface of the handle 1010. The handle 1010 provides a grip fulcrum for the user, making it easy to stabilize the storage compartment 101 during operation. The rubber anti-slip sleeve increases friction to prevent the hand from slipping and improves grip comfort.

[0026] More specifically, an arc-shaped support plate 104 is fixedly connected to one end of the inlet channel 102 near the winding roller 107, and the arc-shaped support plate 104 is located inside the storage compartment 101. The arc-shaped support plate 104 is inclined in the opposite direction. The arc-shaped support plate 104 is used to guide the audio cable body 301 to smoothly transition from the winding roller 107 to the inlet channel 102, avoiding the audio cable body 301 from forming a "hard bend" at the corner, and protecting the internal copper wire and shielding layer.

[0027] It is worth mentioning that a buffer spring 205 is fixedly connected to the side of the slider 201 near the winding roller 107. A buffer baffle 206 is fixedly connected to one end of the buffer spring 205. A second guide hole 207 is provided in the middle of the buffer baffle 206, and a silicone gasket 208 is adhered to the inner wall of the second guide hole 207. A limiting baffle 303 that cooperates with the buffer baffle 206 is installed near the middle of the audio cable body 301. The buffer spring 205 provides elastic cushioning when the audio cable body 301 is wound / stretched, absorbing instantaneous impact force and avoiding... If the audio cable body 301 is subjected to excessive instantaneous force, causing the copper wire to break or the connector to fall off, the buffer baffle 206 further stabilizes the position of the audio cable body 301 through the second guide hole 207, forming an "elastic support" with the spring to disperse the force on the audio cable body 301. The limiting baffle 303 is used to collide with the buffer baffle 206 when the audio cable body 301 retracts to its limit, preventing the audio cable body 301 from continuing to retract, avoiding the connection port 302 from being pulled into the storage compartment 101 and causing damage, while limiting the maximum retracted length of the audio cable body 301.

[0028] It is worth noting that the winding groove 108 is spirally arranged, and the width of the winding groove 108 is the same as the diameter of the audio cable body 301. The spiral structure makes the audio cable body 301 evenly distributed from the middle to both ends when it is wound up, and the force on each turn of the audio cable body 301 is consistent, reducing local bending and protecting the internal copper wires from damage.

[0029] Working Principle: This embodiment provides a retractable and adjustable speaker cable. When the audio cable needs to be retracted, the user holds the handle 1010 and rotates the cross-shaped knob 106, causing the turntable 105 and the winding roller 107 to rotate synchronously. Under the rotation of the winding roller 107, the audio cable body 301 is wound and stored along the spiral winding groove 108. During winding, the audio cable body 301 moves from the middle to both ends of the winding roller 107. At this time, the slider 201 slides along the groove 103 under the drive of the audio cable body 301. The pulley 202 converts sliding friction into rolling friction, making the sliding smoother. The miniature ball bearing 204 in the first guide hole 203 contacts the audio cable body 301, converting the sliding friction of the audio cable body 301 during extension and retraction into rolling friction, further reducing frictional resistance and wear on the audio cable body 301. The arc-shaped support plate 104 guides the audio cable body 301 to smoothly transition with a large radius of curvature, avoiding damage to the audio cable body 301 caused by right-angle bends. The buffer spring 205 and buffer baffle 206 absorb the instantaneous impact force when the audio cable body 301 is retracted or extended, providing good cushioning protection. When the audio cable body 301 retracts to a certain extent, the limiting baffle 303 contacts the buffer baffle 206, preventing the audio cable body 301 from retracting further and preventing the connection port 302 from being pulled into the storage compartment 101. When it is necessary to stretch the audio cable, the user only needs to pull the connection ports 302 at both ends, and the audio cable body 301 will be released from the winding roller 107. The coordinated action of all components makes the stretching process smooth and stable.
