Description

Technical Field

[0001] This utility model relates to the field of loudspeaker structure, and in particular to a spring support structure and a loudspeaker. Background Technology

[0002] Currently, most ultra-narrow speakers on the market suffer from insufficient width (D) space along their short axis, such as... Figure 1 and Figure 2 As shown, it is impossible to place a standard-shaped spider with a complete outer edge to support the voice coil. Therefore, a chamfered elongated spider is usually used as a compromise. This compromise results in a lack of freedom of movement on both sides of the spider in the short axis direction, making the spider relatively narrow and small in the short axis direction. As a result, loudspeakers with this type of structure are very prone to wobbling during operation, leading to poor coil rubbing and damage to the loudspeaker. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spider support structure and speaker. By slotting the side wall of the frame, the wall thickness space of the frame side wall is fully utilized to fix the convex edge of the spider, which effectively solves the problem of the freedom constraint of the spider in the short axis direction and ensures that the voice coil can move axially stably in the magnetic gap without wobbling.

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] Please see Figures 3-6 A spider support structure is disclosed, comprising a frame 100 and a spider 200. The frame 100 supports the entire spider and other speaker components. The spider 200 extends and widens as much as possible in the short axis direction, making it wider in the short axis direction compared to traditional speaker spiders. Its short axis convex edge is glued to the recessed groove of the frame 100, thus fixing the spider. Compared to other speaker spiders that cannot fix the short axis direction, it offers stronger and better stability, ensuring the voice coil moves stably axially within the magnetic gap without wobbling. It also effectively improves the speaker's power handling capacity and low-frequency extension, enhancing product quality and competitiveness.

[0032] The side wall of the basin frame 100 is provided with a first clearance groove 101 and a second clearance groove 102. In this embodiment, the first clearance groove 101 and the second clearance groove 102 are symmetrically arranged about the central axis of the spring body, so that the spring can be stably fixed on the basin frame. It should be noted that the basin frame can be a plastic basin frame or an aluminum alloy basin frame, and the aluminum alloy basin frame is preferably a die-cast aluminum alloy basin frame, depending on the actual needs. The first clearance groove 101 and the second clearance groove 102 are respectively provided on the two side walls of the basin frame, and the bottom surface of the clearance groove can be bonded to the protruding edge of the spring in the short axis direction, so that the spring is more stable and firm in the short axis direction.

[0033] Please see Figure 5The spring wave 200 includes a spring wave body 210, a first short axis protrusion 220, and a second short axis protrusion 230. The first and second short axis protrusions are respectively disposed on the spring wave body, with the first short axis protrusion passing through the first recessed groove and the second short axis protrusion passing through the second recessed groove to increase the groove width of the spring wave in the short axis direction. The spring wave body 210 is used to connect the first short axis protrusion 220 and the second short axis protrusion 230. The first and second short axis protrusions 220 and the second short axis protrusion 230 are respectively used to adhere to the end faces of the first recessed groove 101 and the second recessed groove 102 to give the spring wave good stability in the short axis direction. Furthermore, by creating recessed grooves on the two side walls of the short axis of the basin frame, the wall thickness of the basin frame is used to place the outer protrusion of the spring wave. Compared to commonly available ultra-narrow loudspeakers, this solution effectively increases the groove width of the spider along its short axis, significantly increasing the speaker's linear travel and improving low-frequency sound quality and clarity. It also enhances the stability of the internal support, increasing the speaker's power handling capacity. Furthermore, this solution can be widely applied to ultra-narrow loudspeakers suitable for various scenarios, contributing to improved performance and cost competitiveness, and thus having broad application range.

[0034] Thus, by creating a first and a second clearance groove on the side wall of the speaker frame, the first and second short-axis protrusions of the spider are respectively positioned within the first and second clearance grooves. In other words, by creating grooves in the side wall of the speaker frame, the wall thickness space of the side wall is fully utilized to fix the protrusions of the spider, effectively solving the problem of the spider's degree of freedom constraint in the short-axis direction. This ensures that the voice coil can move axially stably in the magnetic gap without wobbling. Furthermore, this structure increases the groove width in the short-axis direction of the spider, increases the linear stroke of the loudspeaker, and improves the quality of the loudspeaker.

[0035] Furthermore, at least one first clearance groove and at least one second clearance groove are provided. The first clearance groove is used to place and adhere the first short axis protrusion, and the second clearance groove is used to place and adhere the second short axis protrusion. In another embodiment, there may be one or more first clearance grooves. Similarly, there may be one or more second clearance grooves. That is to say, several clearance grooves are formed on one side wall of the frame. The main purpose is to extend the width of the spring in the short axis direction, utilize the wall thickness of the frame to place and fix the outer protrusion of the spring, thereby effectively increasing the groove width of the spring, increasing the linear travel of the speaker, and improving the low-frequency sound quality and clarity of the speaker.

[0036] Please see Figure 4The speaker stand 100 includes a support body 110 and a fixing component 120. The support body has a hollow cavity 111, and the fixing component is disposed within the hollow cavity of the support body. A first clearance groove and a second clearance groove are formed on the side wall of the support body. In this embodiment, the support body and the fixing component are integrally formed. It should be noted that the support body 110 is used to install the fixing component 120 and other speaker components, and the fixing component 120 is used to place and adhere the spring wave.

[0037] Please see Figure 3 and Figure 4 The fixing component 120 includes a central base plate 121, a first long axis stop 122, and a second long axis stop 123. The central base plate is disposed within the hollow cavity of the bracket body. The first long axis stop 122 and the second long axis stop 123 are respectively disposed on the central base plate 121. The central base plate, the first long axis stop, and the second long axis stop together form a spring wave placement area 124. It should be noted that the central base plate 121 is used to install the first long axis stop 122 and the second long axis stop. Block 123, and connected to the side walls of the frame in the two short axis directions, to provide and form a spider placement area 124; the first long axis stop 122 and the second long axis stop 123 are respectively used to place the first long axis protrusion and the second long axis protrusion of the spider, so as to fix and bond the spider in the long axis direction, and with the addition of the side clearance grooves of the frame to fix and bond the spider in the short axis direction, the entire spider can be fixed and bonded around, thereby limiting the spider and ensuring that the voice coil does not wobble when it makes axial movement.

[0038] Further, please refer to Figure 5 The spring 200 further includes a first long axis protrusion 240 and a second long axis protrusion 250. The spring body is disposed on the spring placement area, and the first long axis protrusion is placed on the first long axis stop, and the second long axis protrusion is placed on the second long axis stop, together forming an inner support structure. It should be noted that the first long axis protrusion 240 and the second long axis protrusion 250 can be respectively bonded to the first long axis stop 122 and the second long axis stop 123, so that the edge of the spring in the long axis direction is fixed to the fixing component of the basin frame, thereby limiting its swaying and displacement in the long axis direction.

[0039] It should also be noted that, please refer to Figure 3 and Figure 4The fixing component 120 further includes a first long axis limiting strip 125 and a second long axis limiting strip 126. The first long axis limiting strip is disposed on the first long axis stop, and the second long axis limiting strip is disposed on the second long axis stop. The first and second long axis limiting strips are used to confine the bomb body within the bomb placement area. Thus, by setting the first long axis limiting strip 125 and the second long axis limiting strip 126, installation accuracy and operational stability are ensured.

[0040] Please see Figures 6-9 This utility model also provides a loudspeaker, including the spring support structure 10 as described in any of the above claims, and a diaphragm assembly 20. The diaphragm assembly 20 includes a dust cap 21 and a diaphragm 22. The dust cap 21 is bonded and fixed to the diaphragm 22, and the outer edge of the diaphragm 22 is bonded and fixed to the top surface of the frame, forming an external support structure. It should be noted that the dust cap 21, as a front-end protective barrier of the assembly, is used to prevent dust and foreign objects from entering the loudspeaker, protecting the internal structure from damage. Simultaneously, it can also influence the high-frequency response of the sound to a certain extent, making the treble clearer and more delicate. The outer edge of the diaphragm 22 is bonded and fixed to the top surface of the frame with a high-strength adhesive, forming a stable external support structure. This not only enhances the overall structural strength of the loudspeaker but also ensures the uniform vibration of the diaphragm 22 during vibration, avoiding unnecessary resonance, thereby improving the clarity and dynamic range of the sound output.

[0041] Please see Figures 4-8 The diaphragm assembly 20 also includes a voice coil 23. The frame 100 has a central hole 103, the spider body has a mounting hole 201, and the diaphragm 22 has a central positioning hole 221. The central hole of the frame, the mounting hole of the spider body, and the central positioning hole of the diaphragm are interconnected. The voice coil passes through the central hole of the frame, the mounting hole of the spider body, and the central positioning hole and is then bonded and fixed to the diaphragm. It should be noted that the central positioning hole 221 on the diaphragm 22, the central hole 103 of the frame, and the mounting hole 201 of the spider body are interconnected, forming a voice coil assembly channel. This ensures that the voice coil 23 can accurately pass through all the holes and is ultimately bonded and fixed to the diaphragm 22, forming a robust and efficient vibration system. This connection method not only improves the stability of the speaker structure but also ensures the accurate transmission of sound signals, reduces distortion, and improves sound quality.

[0042] Furthermore, the two edges of the spider along its short axis, namely the first short axis protrusion 220 and the second short axis protrusion 230, are fixed within two recessed grooves on the side of the frame; and its edges along its long axis, namely the first long axis protrusion 240 and the second long axis protrusion 250, are fixed to the support surface inside the frame, forming an independent inner support structure; the outer edge of the diaphragm is bonded and fixed to the top surface of the frame, forming an independent outer support structure; the inner and outer support structures work together to ensure stable operation of the voice coil without wobbling, providing and limiting the axial movement of the voice coil with a preset amplitude. In this way, the power handling capacity of the loudspeaker can be significantly improved, and the low-frequency extension of the loudspeaker can be effectively improved, enhancing the product's quality and competitiveness.

[0043] Please see Figure 6 and Figure 7 The loudspeaker also includes a magnetic circuit assembly 30, which includes a washer 31, a magnet 32, and a U-shaped iron 33. The U-shaped iron is mounted on the frame and has a mounting groove 331. The magnet is bonded to the mounting groove of the U-shaped iron. The washer is located on the end face of the magnet away from the U-shaped iron. The voice coil 23 has a central receiving hole 231, in which the washer is received. The voice coil is also mounted on the magnet. It should be noted that the magnetic circuit assembly 30 and the diaphragm assembly 20 work together to achieve efficient conversion of electrical signals into audio vibrations. The U-shaped iron 33 is used to securely mount the speaker on the frame, providing a stable support structure. The mounting groove 331 on the U-shaped iron 33 ensures that the magnet can be accurately and firmly bonded to the mounting groove 331, avoiding loosening or displacement during vibration, thereby ensuring the stability of the magnetic field. The voice coil 23, acting as a bridge between the diaphragm assembly and the magnetic circuit assembly, is positioned on the magnet and encloses the washer through the central receiving hole 231. The voice coil allows current to flow smoothly, thereby generating precise vibrations under the influence of the magnetic field. The vibration of the voice coil directly drives the vibration of the drum 22, thus converting the electrical signal into sound waves and achieving efficient sound output.

[0044] The washer, magnet, and U-shaped iron are sequentially bonded to form a magnetic circuit assembly, which is then fixed to the frame to form a support structure. The voice coil skeleton passes through the center hole of the spider and diaphragm and is bonded and fixed as a whole, so that the voice coil winding is in the magnetic air gap of the magnetic circuit composed of the washer, magnet, and U-shaped iron; the dust cap is bonded and fixed to the diaphragm to form a diaphragm assembly; the loudspeaker achieves coupling with the air through the diaphragm assembly.

[0045] When an audio current is passed through the coil winding of the voice coil in the magnetic air gap, it is subjected to the Lorentz force and reciprocates at the same frequency as the audio current. Through the related bonding structure, it drives the diaphragm assembly, which consists of a drum paper and a dust cap, to also reciprocate. The reciprocating motion of the diaphragm assembly creates a compression and expansion effect on the air volume in front of and behind it, causing changes in the density of the surrounding air and generating a disturbing audio pressure wave.

[0046] Thus, by creating grooves on both sides of the short axis of the speaker frame, the outer edge of the spider is placed within the wall thickness of the frame. Compared to commonly used ultra-narrow speakers, this design effectively increases the groove width of the spider along the short axis, significantly increasing the speaker's linear travel and improving low-frequency sound quality and clarity. Compared to commonly used ultra-narrow speakers, this design also enhances the stability of the internal support and increases the speaker's power handling capacity. This design can be widely applied to ultra-narrow speakers suitable for various scenarios, contributing to improved performance and cost competitiveness, and has broad application prospects.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
