Description

Technical Field

[0001] This invention relates to the field of loudspeaker equipment technology, specifically a loudspeaker with drop and impact resistance. Background Technology

[0002] A loudspeaker is an electroacoustic transducer that converts electrical signals into sound signals. It is widely used in public address systems, portable amplification equipment, musical instrument speakers, and outdoor portable audio systems. A typical handheld or portable loudspeaker usually consists of a speaker grille (horn), a controller (including power amplifier circuitry and battery), and a handle. The speaker grille is used for directional propagation of sound waves, and the controller is used for signal processing and power amplification.

[0003] Current handheld or portable loudspeakers still have several shortcomings in terms of impact protection: First, most products only have simple rubber sleeves or silicone rings on the edge of the speaker enclosure or the tail of the controller. These cushioning components are held in place by friction alone. When the speaker falls from a certain height and lands on its edge, the instantaneous impact force causes the rubber sleeve to elastically deform and slide along the impact direction, easily detaching from the edge of the shell. This allows the speaker enclosure or controller to directly contact the ground in subsequent impacts, resulting in the instantaneous loss of cushioning protection, leading to shell cracking, loosening of internal components, or circuit board breakage. Second, traditional cushioning sleeves lack a mechanism to automatically strengthen the connection during impact, relying entirely on the interference fit during initial installation. After multiple drops, the rubber ages and loosens, further reducing the connection's strength and increasing the risk of detachment. Third, the plastic speaker enclosure has excellent elastic recovery characteristics after impact, causing the speaker to bounce repeatedly like a ball. Each bounce generates new impacts, continuously damaging the shell and internal solder joints. Traditional equipment lacks a design to quickly reduce rebound height and suppress continuous bouncing after the initial impact, resulting in a significantly increased probability of fall injury. Fourth, the fixing methods between the buffer sleeve and the shell (such as adhesive, threads, or clips) are either difficult to disassemble after assembly, making it difficult to replace worn or aged buffer components, or the connection strength is insufficient to guarantee effective adhesion during impact. In addition, conventional rubber sleeves are difficult to install due to the high coefficient of friction between the rubber and the plastic shell, reducing the convenience of maintenance. Summary of the Invention

[0004] (a) Technical problems to be solved This invention provides a speaker with drop and impact resistance, solving the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a loudspeaker with drop and impact resistance, comprising a soundproof cover, a controller provided at the tail of the soundproof cover, and a connecting tube, the connecting tube being fixedly connected to the output end of the controller, the end of the connecting tube away from the controller being slidably inserted into the outer surface of the tail of the soundproof cover, and a handle being fixedly connected to the bottom outer surface of the connecting tube.

[0006] According to one embodiment of the present invention, the loudspeaker further includes: a protective component, the protective component being movably mounted on the outer surface of the speaker enclosure; wherein the protective component includes a rubber sleeve, the rubber sleeve being movably fitted onto the outer edge of the speaker enclosure, and four rubber sleeves being fixedly spaced along the central axis of the speaker enclosure; the protective component further includes a rubber ring, the rubber ring being fixedly fitted onto the outer surface of the controller, wherein the tail of the rubber ring protrudes from the controller, that is, the control panel of the controller is located inside the rubber ring.

[0007] According to one embodiment of the present invention, air tubes are symmetrically fixedly connected to both ends of the rubber sleeve, wherein four rubber sleeves are connected in a ring shape by four air tubes, an air cavity is opened in the outer wall of the rubber sleeve, and the air cavity is connected to the air tube, and the air tube has stronger expansion capacity than the rubber sleeve.

[0008] According to one embodiment of the present invention, four isolation seats are fixedly provided on the outer edge of the loudspeaker cover, wherein a rubber sleeve is disposed between each pair of isolation seats, and a filling groove is provided through both ends of the isolation seat, and an opening is provided on the outer side of the filling groove, wherein the cross-sectional diameter of the filling groove is larger than the width of the opening.

[0009] According to one embodiment of the present invention, a retainer is fixedly embedded on the inner surface of the rubber sleeve, wherein the retainer is made of plastic.

[0010] According to one embodiment of the present invention, the tail of the loudspeaker is provided with a compression cavity, wherein the end of the connecting tube away from the controller is simultaneously frictionally slidably inserted into the compression cavity, and the overall weight of the connecting tube and the controller is consistent with the weight of the loudspeaker, while the loudspeaker and the connecting tube are kept in an expanded state under normal conditions.

[0011] According to one embodiment of the present invention, four air pressure grooves are provided at fixed intervals along the outer edge of the loudspeaker cover, wherein the air pressure grooves are arranged opposite to the rubber sleeve, and the wall of the loudspeaker cover is also provided with a channel, and the extrusion chamber is connected to the air pressure grooves through the channel.

[0012] According to one embodiment of the present invention, a positioning bolt is elastically slidably inserted through the outer surface of the speaker cover near the controller, wherein the inner end of the positioning bolt is connected to the air pressure groove, and the positioning bolt does not initially protrude from the outer surface of the speaker cover, and a positioning hole is provided on the inner surface of the sleeve to align with the positioning bolt.

[0013] When you need to use this speaker, you can hold the handle and operate the controller to make a sound. By putting rubber sleeves and rubber rings on the outer edge of the speaker enclosure and the outer surface of the controller, the corners of the speaker can be protected.

[0014] (III) Beneficial Effects This invention provides a speaker with drop and impact resistance. It has the following beneficial effects: (i) This speaker has a drop-resistant and impact-resistant function. When the speaker is accidentally dropped from a height, no matter what angle it falls from, the rubber sleeve or rubber ring will always make contact with the ground first, thereby providing a lot of impact cushioning for the speaker body. This avoids the problem of conventional speakers where the speaker cover or controller directly impacts the ground when it falls, causing it to break or crack or even seriously damage the internal components.

[0015] (II) This speaker, which is drop-resistant and impact-resistant, is subject to the following limitations due to the angle at which it falls: when the rubber sleeve contacts the ground first, it will be subjected to a large compressive deformation force, which will cause the air cavity of the rubber sleeve to be compressed instantly. At this time, the compressed air cavity will send its internal air pressure to the air tubes at both ends. The expansion force of the air tube is greater than that of the air cavity, so the air tube expands first during the collision, which makes the air tube firmly expand in the filling groove of the isolation seat and prevents it from falling out through the opening. This locks the four rubber sleeves and prevents the rubber sleeves from being misaligned and detached due to the compressive force during the drop and collision. At the same time, under normal use, the air tube can pass through the opening smoothly and the rubber sleeves can be easily removed. This ensures that the rubber sleeves are easy to disassemble and also improves its working stability and connection stability.

[0016] (III) This speaker, with its drop-resistant and impact-resistant function, will cause the controller and connecting tube to slide into the compression chamber immediately upon contact with the ground during a drop, due to gravity. This compression will compress the internal cavity of the chamber. As the controller and connecting tube move, the overall center of the speaker will rapidly descend, significantly reducing the height and number of bounces after the speaker collides with the ground. This avoids the problem of repeated bounces caused by the plastic properties of the speaker cover, which leads to repeated collisions and damage to the speaker cover, as is common with conventional speakers. This further enhances the protection of the speaker itself. The compression chamber, once compressed, delivers internal air pressure through the channels to the air pressure groove, increasing the internal air pressure. This causes the positioning bolt to move outward from the speaker enclosure and into the positioning hole of the clip on the rubber sleeve. This further enhances the fixation of the rubber sleeve during a fall or collision, preventing it from detaching and thus improving the protection of the speaker. Additionally, the plastic clip on the rubber sleeve improves the smoothness of loading, avoiding the problem of high friction and loading difficulties caused by direct contact between the rubber sleeve and the speaker enclosure.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] First embodiment: as follows Figures 1 to 7 As shown, the present invention provides a technical solution: a loudspeaker with drop and impact resistance, including a soundproof cover 1, a controller 2 disposed at the rear of the soundproof cover 1, and further comprising: Connecting pipe 3 is fixedly connected to the output end of controller 2. The end of connecting pipe 3 away from controller 2 is slidably inserted into the outer surface of the tail of the loudspeaker cover 1. A handle 4 is fixedly connected to the bottom outer surface of connecting pipe 3.

[0021] Second embodiment: as follows Figures 1 to 7 As shown, the speaker also includes: Protective component 5 is movably mounted on the outer surface of the loudspeaker cover 1; The protective component 5 includes a rubber sleeve 51, which is movably fitted onto the outer edge of the loudspeaker cover 1. Four rubber sleeves 51 are fixedly spaced along the central axis of the loudspeaker cover 1. The protective component 5 also includes a rubber ring 52, which is fixedly sleeved on the outer surface of the controller 2. The tail of the rubber ring 52 protrudes from the controller 2, meaning that the control panel of the controller 2 is located inside the rubber ring 52.

[0022] The two ends of the rubber sleeve 51 are symmetrically fixed with air tubes 53. The four rubber sleeves 51 are connected to form a ring through the four air tubes 53. An air cavity 54 is opened in the outer wall of the rubber sleeve 51 and the air cavity 54 is connected to the air tube 53. At the same time, the expansion capacity of the air tube 53 is stronger than that of the rubber sleeve 51.

[0023] Four isolation seats 55 are fixedly installed on the outer edge of the loudspeaker cover 1. Rubber sleeves 51 are installed between two isolation seats 55. Filling grooves 56 are opened through both ends of the isolation seats 55, and openings 57 are provided on the outer side of the filling grooves 56. The cross-sectional diameter of the filling grooves 56 is larger than the width of the openings 57.

[0024] A retainer 58 is fixedly embedded on the inner surface of the rubber sleeve 51, wherein the retainer 58 is made of plastic.

[0025] The rear end of the loudspeaker cover 1 is provided with a compression chamber 59, in which the end of the connecting tube 3 away from the controller 2 is simultaneously rubbed and slidably inserted into the compression chamber 59, and the overall weight of the connecting tube 3 and the controller 2 is consistent with the weight of the loudspeaker cover 1. At the same time, the loudspeaker cover 1 and the connecting tube 3 are kept in an expanded state under normal conditions.

[0026] Four air pressure grooves 510 are provided at fixed intervals along the outer edge of the loudspeaker cover 1. The air pressure grooves 510 are positioned opposite the rubber sleeve 51. A channel 511 is also provided in the wall of the loudspeaker cover 1, and the extrusion chamber 59 is connected to the air pressure grooves 510 through the channel 511.

[0027] A positioning bolt 512 is elastically slidably inserted through the outer surface of the side of the loudspeaker cover 1 near the controller 2. The inner end of the positioning bolt 512 is connected to the air pressure groove 510. Initially, the positioning bolt 512 does not protrude from the outer surface of the loudspeaker cover 1. The inner surface of the sleeve 58 is provided with a positioning hole 513 aligned with the positioning bolt 512.

[0028] When in operation, the speaker can be used by holding the handle 4 and operating the controller 2 to produce sound. By covering the outer edge of the speaker housing 1 and the outer surface of the controller 2 with rubber sleeves 51 and rubber rings 52 respectively, the corners of the speaker are protected. If the speaker is accidentally dropped from a height, regardless of the angle of impact, the rubber sleeve 51 or rubber ring 52 will always make initial contact with the ground, providing significant impact cushioning for the speaker body. This avoids the problem of conventional speakers where the speaker housing 1 or controller 2 directly impacts the ground upon drop, causing breakage, cracking, or even severe damage to internal components. Due to the limitations of the speaker's drop angle, when the rubber sleeve 51 makes initial contact with the ground... The rubber sleeve 51 is subjected to a large compressive deformation force, which instantly compresses the air cavity 54 of the rubber sleeve 51. At this time, the compressed air cavity 54 delivers its internal air pressure to the air pipes 53 at both ends. The expansion force of the air pipes 53 is greater than that of the air cavity 54, so the air pipes 53 expand first during the collision. This makes the air pipes 53 firmly expand in the filling groove 56 of the isolation seat 55 and prevents them from falling out through the opening 57. This locks the four rubber sleeves 51, preventing them from being misaligned and detached during the impact. At the same time, under normal use, the air pipes 53 can pass through the opening 57 smoothly, and the rubber sleeves 51 can be easily removed, thus ensuring that the rubber sleeves 51 are securely in place. While facilitating disassembly, it also improves its operational and connection stability. Upon impact with the ground, the controller 2, along with the connecting pipe 3, slides into the compression chamber 59 under the influence of gravity, thus compressing the internal cavity of the compression chamber 59. Simultaneously, as the controller 2 and connecting pipe 3 move, the overall center of the speaker rapidly descends, significantly reducing the height and number of bounces after the speaker collides with the ground. This avoids the problem of repeated bounces caused by the plastic properties of the speaker cover 1 during drops, which can easily damage the cover 1 due to multiple impacts. This further enhances the protection of the speaker itself, and the compression chamber 59 is... After compression, the internal air pressure is delivered to the air pressure groove 510 through the channel 511, thereby increasing the internal air pressure of the air pressure groove 510. This causes the positioning bolt 512 to move outward from the speaker cover 1 and enter the positioning hole 513 of the clip 58 on the rubber sleeve 51. This further enhances the fixing effect of the rubber sleeve 51 by the insertion of the positioning bolt 512 and the positioning hole 513 during a drop or collision, preventing the rubber sleeve 51 from detaching and thus further improving the protection of the speaker. At the same time, the plastic clip 58 on the rubber sleeve 51 can also improve the smoothness of the rubber sleeve 51 during loading, avoiding the problem of high friction and loading difficulties caused by direct contact between the rubber sleeve 51 and the speaker cover 1.
