Description

Technical Field

[0001] This utility model relates to a loudspeaker. Background Technology

[0002] With the development of electronic technology and the widespread adoption of smart wearables, competition in the smartwatch industry is becoming increasingly fierce. In order to meet people's needs and seize the market first, smartwatches need to be equipped with more functions during development. As a wearable device, smartwatches are widely used in daily life and sports scenarios.

[0003] However, in complex usage environments (such as sports, swimming, rainy days, etc.), waterproof performance has become an important requirement in smartwatch design, and waterproof speakers have also become a key research and development target. Waterproof speakers usually use non-suspended lead speakers. However, although non-suspended lead speakers improve waterproof performance through centering supports, the introduction of centering supports increases costs and occupies additional internal space, resulting in the size or weight of the speaker not meeting the compact requirements of smartwatches.

[0004] Traditional suspended lead loudspeakers require two slots in the frame to facilitate cable routing, as the lead needs to extend from the frame to ensure the voice coil wire is soldered to the pads. However, these slots prevent the diaphragm from fully adhering to the frame. During waterproofing tests, water flow impacts the diaphragm, creating pressure. This causes the diaphragm to collapse due to the lack of frame support below the slots, allowing water molecules to enter the loudspeaker. Filling the slots with adhesive is difficult; too little adhesive risks leakage, while too much risks overflowing onto the diaphragm surround. Therefore, the lack of support at the slots below the diaphragm makes the diaphragm vulnerable to vibration or external forces, leading to poor adhesion or even separation between the diaphragm and frame, resulting in inadequate waterproofing.

[0005] Therefore, designing a speaker that can meet waterproofing requirements while maintaining excellent acoustic performance within a limited space is a technical challenge that urgently needs to be solved in the smartwatch industry. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a loudspeaker.

[0007] The purpose of this utility model is achieved through the following technical measures: a loudspeaker, including a frame with a wire outlet hole, a magnetic circuit assembly and a vibration assembly on the frame, the vibration assembly including a diaphragm, a dome on the diaphragm, and a voice coil on the dome, characterized in that: a groove is provided on the side of the frame facing the diaphragm, a gasket is provided in the groove, and the gasket is located between the diaphragm and the frame.

[0008] As an improvement, the depth of the groove is greater than the height of the washer ring.

[0009] As a further improvement, the gasket is a complete planar ring, and the gasket is provided with several adhesive storage grooves.

[0010] As a further improvement, there are four glue storage grooves, which are arc-shaped. Each of the rounded corners of the gasket is provided with a glue storage groove, and the arc of the glue storage groove matches the arc of the rounded corner of the gasket.

[0011] As a further improvement, there are eight glue storage grooves, and two opposing glue storage grooves are provided at each rounded corner of the gasket, with the arc formed by the two opposing glue storage grooves matching the arc of the rounded corner of the gasket.

[0012] As a further improvement, there are eight glue storage grooves, and two parallel glue storage grooves are provided at each rounded corner of the gasket ring, and the curvature of the glue storage grooves matches the curvature of the rounded corner of the gasket ring.

[0013] As a further improvement, there are sixteen adhesive storage grooves, and two opposing and parallel adhesive storage grooves are provided at each rounded corner of the gasket, with the arc formed by the two opposing adhesive storage grooves matching the arc of the rounded corner of the gasket.

[0014] As a further improvement, the washer can be a metal washer or a hard plastic washer.

[0015] As a further improvement, the magnetic circuit assembly includes a magnetic cover, a magnet disposed within the magnetic cover, and pole pieces disposed on the magnet.

[0016] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0017] First: Perfect sealing effect: This utility model adds a gasket ring, which is located between the diaphragm and the frame. The gasket ring is a complete flat surface. The complete flat surface of the gasket ring can provide support for the diaphragm, especially the diaphragm at the cable outlet position on the frame. During the waterproof performance test, the diaphragm at the cable outlet position on the frame is supported, preventing the diaphragm from collapsing. This prevents water molecules from entering the speaker through the gap at the cable outlet position on the frame, thus significantly improving the waterproof performance. At the same time, the tight fit between the gasket ring and the diaphragm can form a reliable sealing interface, effectively preventing water from entering and avoiding sound quality distortion caused by poor sealing.

[0018] Second: Improved waterproof performance: The adhesive storage groove is added to the gasket ring. The adhesive storage groove serves two purposes: firstly, it stores adhesive to ensure sufficient contact area between the diaphragm, adhesive, and gasket ring; secondly, it provides a certain reverse pulling force when water impacts the diaphragm and the diaphragm is concave inward, ensuring complete adhesion between the diaphragm and the gasket ring. Under external pressure, it also has a certain tensile strength. At the same time, the arc-shaped structure of the adhesive storage groove has a certain anti-slip effect, providing a certain frictional force to the diaphragm under the pressure of water molecules, which can pull the diaphragm and ensure that the diaphragm is not easily collapsed, thereby significantly improving the waterproof performance.

[0019] Third: Enhanced stability: The fully fitted pad ring design provides better support for the diaphragm, reducing the deformation of the diaphragm under high-frequency or long-term vibration, thereby improving the stability and consistency of sound quality.

[0020] Fourth: Compact design: Compared with the traditional non-suspended lead wire design, this design reduces the need for additional space by optimizing the way the spacer ring and the diaphragm are combined, making the speaker more suitable for the compact requirements of smartwatches;

[0021] Fifth: Cost reduction: Compared with speakers without suspended leads, the elimination of the centering support and the use of a gasket design reduce material and manufacturing costs while improving waterproof performance, making it an efficient and economical solution.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example 1: As shown in the attached document Figure 1 -Appendix Figure 3 As shown, a loudspeaker includes a frame 2 with a wire outlet 1, a magnetic circuit assembly and a vibration assembly on the frame 2; the magnetic circuit assembly includes a magnetic cover 3, a magnet 4 disposed inside the magnetic cover 3, and a pole piece 5 disposed on the magnet 4; the vibration assembly includes a diaphragm 6, a dome 7 disposed on the diaphragm 6, and a voice coil 8 disposed on the dome 7.

[0034] The frame 2 has a groove 21 on the side facing the diaphragm 6, and a washer 9 is provided in the groove 21. The washer 9 is located between the diaphragm 6 and the frame 2. The washer 9 is a metal washer or a hard plastic washer. The washer 9 must have a certain hardness and can be stamped to ensure that it provides support for the diaphragm 6, especially the diaphragm 6 at the wire outlet 1.

[0035] The depth of the groove 21 is greater than the height of the gasket 9. This arrangement allows the groove 21 to form a barrier against the gasket 9, preventing the glue from overflowing.

[0036] The washer 9 is a complete planar ring. The complete planar washer 9 can provide support for the diaphragm 6, especially the diaphragm 6 at the position of the cable outlet 1 on the frame 2.

[0037] The gasket 9 has four arc-shaped adhesive storage grooves 91, one at each rounded corner of the gasket 9. The arc of the adhesive storage groove 91 matches the arc of the rounded corner of the gasket 9. The adhesive storage grooves 91 serve two purposes: firstly, to store adhesive and ensure sufficient contact area between the diaphragm 6, the adhesive, and the gasket 9; and secondly, to provide a certain reverse pulling force when water impacts the diaphragm 6 and causes it to cave inward, ensuring complete adhesion between the diaphragm 6 and the gasket 9. Under external pressure, the grooves also possess a certain tensile strength. Furthermore, the arc-shaped structure of the adhesive storage grooves 91 provides a certain anti-slip effect, offering friction against the caved-in diaphragm 6 under water molecule pressure, thus preventing the diaphragm 6 from collapsing and significantly improving waterproof performance.

[0038] Example 2: As shown in the attached document Figure 4 As shown, the structure is the same as that in Embodiment 1, except that: there are eight glue storage grooves 91, and two opposing glue storage grooves 91 are provided at each rounded corner of the gasket 9, and the arc formed by the two opposing glue storage grooves 91 matches the arc of the rounded corner of the gasket 9.

[0039] Example 3: As shown in the attached document Figure 5 As shown, the structure is the same as that in Embodiment 1, except that: there are eight glue storage grooves 91, and two parallel glue storage grooves 91 are provided at each rounded corner of the gasket 9, and the curvature of the glue storage grooves 91 matches the curvature of the rounded corner of the gasket 9.

[0040] Example 4: As attached Figure 6 As shown, the structure is the same as in Embodiment 1, except that: there are sixteen glue storage grooves 91, and two opposite and parallel glue storage grooves 91 are provided at each rounded corner of the gasket 9, and the arc formed by the two opposite glue storage grooves 91 matches the arc of the rounded corner of the gasket 9.

[0041] In summary, Embodiments 2, 3, and 4 appropriately increased the number of adhesive storage tanks 91. The number of adhesive storage tanks 91 can be selected according to the actual size of the product. Of course, the number of adhesive storage tanks 91 is not limited to the number listed in the above embodiments and can be changed as needed.

[0042] This novel invention has the following features:

[0043] Complete sealing effect: The tight fit between the gasket 9 and the diaphragm 6 can form a reliable sealing interface, effectively preventing water from entering and avoiding sound quality distortion caused by poor sealing.

[0044] Enhanced stability: The fully fitted pad ring 9 provides better support for the diaphragm 6, reducing the deformation of the diaphragm 6 under high-frequency or long-term vibration, thereby improving the stability and consistency of sound quality.

[0045] Compact design: Compared with the traditional non-suspended lead wire design, this design reduces the need for additional space by optimizing the combination of the pad ring 9 and the diaphragm 6, making the speaker more suitable for the compact requirements of smartwatches.

[0046] Cost reduction: Compared to speakers without suspended leads, the elimination of the centering support and the use of the spacer ring 9 design reduce material and manufacturing costs while improving waterproof performance, making it an efficient and economical solution.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
