Description

Technical Field

[0001] This utility model belongs to the technical field of conference sound reinforcement devices, and in particular relates to a portable energy storage mobile conference sound reinforcement device. Background Technology

[0002] Currently, in the field of conference sound reinforcement technology, with the diversification of conference scenarios such as business exchanges and academic seminars, higher demands are being placed on the portability, assembly efficiency, and long-term stability of sound reinforcement equipment. Most conference sound reinforcement devices currently on the market suffer from the following technical pain points.

[0003] Among them, existing conference sound reinforcement devices often adopt an integrated design or a complex bolted connection structure. Although the integrated design saves assembly steps, the overall size is large and the weight is high. When it is necessary to frequently change the conference venue (such as temporary conference rooms or outdoor seminar areas), it is difficult for a single person to carry it and occupies a lot of transportation space. The split device with bolted connection requires tools to tighten each bolt during assembly and loosen them one by one during disassembly. The whole process takes a long time. In scenarios where the conference preparation time is tight, it is easy to delay the progress of the equipment to be put into use and seriously affect the efficiency of conference preparation. In meeting scenarios, equipment is often exposed to different environmental conditions. For example, indoor meetings may generate moisture due to changes in air humidity, while outdoor temporary meetings are prone to contact with impurities such as dust and sand. Existing sound reinforcement devices have speakers that are directly exposed or only protected by simple grilles, lacking a reliable sealing structure. When moisture, dust and other impurities adhere to the speaker surface, it will cause the speaker diaphragm damping to increase, affecting the clarity and sound quality of the sound.

[0004] To address these issues, we propose a portable energy-storage mobile conference sound reinforcement device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a portable energy storage mobile conference sound amplification device that effectively blocks external dust, moisture, and other impurities from entering.

[0006] In view of this, the present invention provides a portable energy-storing mobile conference sound reinforcement device, comprising: a first speaker, wherein a first groove is formed on the side wall of the first speaker, and a sound-emitting unit is installed in the first groove; a second speaker, wherein a second groove is formed on the side wall of the second speaker, and the sound-emitting units on the first speaker and the second speaker are respectively located in the first groove and the second groove; a quick-installation mechanism, wherein the first speaker and the second speaker are installed by the quick-installation mechanism; and a protective component, wherein the protective component includes a sealing gasket fixedly installed on the side wall of the first speaker; wherein, when the first speaker and the second speaker are in a closed assembly state, they can apply a compressive force to the sealing gasket, thereby forming a seal between the first groove and the second groove after the mating is achieved.

[0007] Furthermore, the quick-installation mechanism includes two slots symmetrically opened on both sides of the first speaker, each slot having a limiting groove connected to its inner wall, and plugs symmetrically assembled on both sides of the second speaker, each plug having a limiting block fixedly connected to its side wall, the limiting block being adapted to the plug.

[0008] Furthermore, the limiting block has a cross-section in the shape of a right-angled trapezoid, and the inclined surface of the limiting block is set in the same direction as the insertion of the plug into the slot.

[0009] Furthermore, each of the insert blocks has an elastic element fixedly connected to its side wall, and the other end of each elastic element is fixedly connected to the second speaker side wall. A handle is fixedly installed on each of the two corresponding insert block side walls.

[0010] Furthermore, both the first and second speakers have connection holes on their tops, and the two connection holes are connected by wires.

[0011] Furthermore, both the first and second speakers are symmetrically mounted with fixed bases on their tops, and each fixed base has a bracket rotatably mounted on one side, with a handle rotatably mounted on the other end of each bracket.

[0012] Furthermore, the cross-sectional shape of the handle is semi-circular, and the two handles are joined together to form a cylindrical structure.

[0013] The beneficial effects of this utility model are: The quick-release mechanism between the first and second speakers greatly simplifies the installation and disassembly process, allowing users to quickly assemble and put the device into use in meeting scenarios. It also facilitates subsequent storage and transportation, improving the portability of the device. The sealing gasket in the protective component forms a reliable seal due to the squeezing force of the side walls when the first and second speakers are closed and assembled. This effectively prevents external dust, moisture, and other impurities from entering the first and second grooves after docking, avoiding erosion or damage to the sound units inside the grooves, extending the service life of the sound units, and thus ensuring the long-term stable operation of the entire sound reinforcement device.

[0020] Reference Figures 1 to 4 A portable energy-storage mobile conference sound reinforcement device, comprising: A first speaker 1 has a first groove 3 on its side wall, and a sound-generating unit 31 is installed in the first groove 3. The second speaker 11 has a second groove 32 on its side wall, and the sound-emitting units 31 on the first speaker 1 and the second speaker 11 are respectively located in the first groove 3 and the second groove 32. Quick-installation mechanism: The first speaker 1 and the second speaker 11 are installed via the quick-installation mechanism; The protective assembly includes a sealing gasket 34 fixedly mounted on the side wall of the first speaker 1; The first speaker 1 and the second speaker 11 are in a closed assembly state and can apply a compressive force to the sealing gasket 34. Through this compressive force, a seal is formed between the first groove 3 and the second groove 32 after they are mated together.

[0021] This application integrates the sound-generating unit 31, which performs the sound amplification function, into the first groove 3 and the second groove 32. During use, the two sound-generating units 31 will not come into contact with each other. The quick-release mechanism can quickly connect and disconnect the two: when assembly is required, the quick-release mechanism is used to fix them; when storage or transportation is required, the quick-release mechanism is used to release the fixation, disassemble the two speakers, and reduce the overall volume and weight. The sealing gasket 34 of the protective component is made of elastic rubber and is fixed to the side wall of the first speaker 1. When the first speaker 1 and the second speaker 11 are closed and assembled, their side walls will approach each other and exert a squeezing force on the sealing gasket 34, causing the sealing gasket 34 to undergo elastic deformation and tightly fill the joint gap between the first speaker 1 and the second speaker 11. At the same time, it covers the joint edge of the first groove 3 and the second groove 32, forming a continuous sealing surface, preventing external impurities from entering the groove through the gap, and thus protecting the sound-generating unit 31.

[0022] In the example of this application, the quick-installation mechanism includes two slots 2 symmetrically opened on both sides of the first speaker 1, and a limiting groove 21 is opened in the inner wall of each slot 2. Insert blocks 23 are symmetrically assembled on both sides of the second speaker 11, and a limiting block 24 is fixedly connected to the side wall of each insert block 23. The limiting block 24 is adapted to the insert block 23.

[0023] As a preferred example of this utility model, the slots 2 on both sides of the first speaker 1 are concave structures, and the limiting grooves 21 on the inner wall of the slots 2 are further concave extensions; the inserts 23 on both sides of the second speaker 11 are convex structures that match the slots 2, and the limiting blocks 24 on the side walls of the inserts 23 are convex structures that match the limiting grooves 21; during assembly, the user aligns the inserts 23 of the second speaker 11 with the slots 2 of the first speaker 1 and applies a pushing force along the axial direction of the slots 2. The inserts 23 will slide along the inner wall of the slots 2. When the inserts 23 slide to the preset position, the limiting blocks 24 on the side walls of the inserts 23 will enter the limiting grooves 21 on the inner wall of the slots 2. The inner wall of the limiting grooves 21 will form a radial constraint on the limiting blocks 24, preventing the inserts 23 from coming out in the opposite direction along the axial direction of the slots 2, and at the same time restricting the inserts 23 from moving in a direction perpendicular to the axial direction of the slots 2, thereby achieving relative fixation of the first speaker 1 and the second speaker 11 and completing the assembly.

[0024] In the example of this application, the cross-section of the limiting block 24 is a right trapezoid, and the inclined surface of the limiting block 24 is set in the same direction as the insertion block 23 is inserted into the slot 2.

[0025] As a preferred example of this utility model, the right-angled trapezoidal structure of the limiting block 24 plays a dual role of guiding and locking during the assembly process. Since the inclined surface of the limiting block 24 is consistent with the insertion direction of the insert 23, in the initial stage of inserting the insert 23 into the slot 2, the entrance edge of the slot 2 will contact the inclined surface of the limiting block 24. The inclination angle of the inclined surface will decompose the axial thrust applied by the user into a part of the radial force, causing the limiting block 24 to produce a slight radial deformation, reducing the resistance when inserting the insert 23, and guiding the insert 23 to smoothly enter the depth of the slot 2. When the insert 23 is fully inserted into the slot 2, the right-angled side of the limiting block 24 will fit against the vertical inner wall of the limiting groove 21. If the insert 23 has a tendency to come out in the opposite direction, the right-angled side of the limiting block 24 will form a rigid contact with the inner wall of the limiting groove 21. The right-angled structure cannot decompose the release force like the inclined surface, thus generating strong resistance to the insert 23, preventing the insert 23 from coming out, achieving reliable locking, and ensuring the stability of the connection between the first speaker 1 and the second speaker 11.

[0026] In the example of this application, each of the insert blocks 23 is fixedly connected to an elastic element 22 on its sidewall. The elastic element 22 may be made of hard plastic and is used to move the limiting block 24 on the insert block 23. The other end of the elastic element 22 is fixedly connected to the sidewall of the second speaker 11. A handle 25 is fixedly installed on the sidewall of each of the two corresponding insert blocks 23.

[0027] As a preferred example of this utility model, the elastic element 22 has elastic deformation capability. One end of it is fixed to the insert block 23 and the other end is fixed to the side wall of the second speaker 11. In its natural state, the elastic element 22 will generate an outward pushing force on the insert block 23, keeping the insert block 23 in the extended state. At this time, the limiting block 24 is in a position that facilitates insertion into the limiting groove 21. When disassembling, the user applies pressure to the inside through the lifting handle 25. The lifting handle 25 transmits the force to the insert block 23, causing the insert block 23 to overcome the elastic force of the elastic element 22 and move towards the side wall of the second speaker 11. The insert block 23 simultaneously drives the limiting block 24 of the side wall to exit from the limiting groove 21, releasing the constraint of the limiting groove 21 on the limiting block 24.

[0028] In the example of this application, both the first speaker 1 and the second speaker 11 have a connection hole 15 on their tops, and the two connection holes 15 are connected by a wire.

[0029] As a preferred example of this utility model, both the first speaker 1 and the second speaker 11 integrate circuit modules directly related to the sound reinforcement function (including signal processing module, sound unit driving module, power supply module, etc.). The connection hole 15 opened on the top of both speakers is an external extension structure of the core circuit interface inside the speakers. Its core function is to build a conduction channel for the internal circuits of the two speakers.

[0030] When the two connection holes 15 are connected by wires, the wires will form a stable conductive path between the first speaker 1 and the second speaker 11. The conductive path can transmit the audio control signals (such as play, pause, volume adjustment, sound effect parameters and other command signals) output by the control circuit of the second speaker 11 to the sound unit driver module of the first speaker 1; at the same time, the control signals of the first speaker 1 itself can also be transmitted in reverse to the corresponding driver module of the second speaker 11, ensuring that the control commands received by the two speakers are completely consistent and realizing sound synchronization.

[0031] The conductive path also enables power exchange between the two speakers—power can be transmitted from one speaker (such as the first speaker 1 with a built-in main power supply module) to the other speaker (such as the second speaker 11 that relies on external power supply), ensuring that the internal circuits of both speakers are in a stable working state; the power signal coordination can also further calibrate the start-up sequence of the two speaker units, avoiding the problem of asynchronous sound production caused by the power supply delay of a single speaker.

[0032] In addition, both the first speaker 1 and the second speaker 11 can have built-in batteries to provide power.

[0033] In the example of this application, the first speaker 1 and the second speaker 11 are symmetrically mounted with fixed seats 12 on their tops. Each fixed seat 12 is rotatably mounted with a bracket 13 on one side. Each of the two brackets 13 is rotatably mounted with a handle 14 on the other end. Bearings are mounted on the side walls of the fixed seats 12 and the brackets 13. A rotating shaft is fixedly mounted on the inner shaft of the bearing. The other end of each rotating shaft is fixedly connected to the corresponding bracket 13 and handle 14.

[0034] As a preferred example of this utility model, the fixed base 12 provides a fixed support point for the bracket 13. The bracket 13 is connected to the fixed base 12 via a rotating shaft and can rotate around the fixed base 12 in the horizontal or vertical direction. The handle 14 is connected to the other end of the bracket 13 via a rotating shaft and can rotate around the bracket 13. When carrying the device, the user can adjust the angle between the bracket 13 and the fixed base 12 by rotating the bracket 13 according to their hand gripping habits, and at the same time adjust the angle between the handle 14 and the bracket 13, so that the handle 14 is in a position that is easy for the hand to grip, reducing hand fatigue during carrying.

[0035] In the example of this application, the cross-sectional shape of the handle 14 is semi-circular, and the two handles 14 are spliced ​​together to form a cylindrical structure.

[0036] As a preferred example of this utility model, the semi-circular cross-section design of the handle 14 conforms to the curvature requirements of the hand when holding it. When the first speaker 1 and the second speaker 11 are assembled together, the flat sides of the two semi-circular handles 14 fit together to form a complete cylindrical structure. When the user's palm wraps around the handle 14, the cylindrical surface can make uniform contact with the contour of the palm and fingers, dispersing the pressure when holding and reducing the local pressure on the hand.

[0037] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
