Description

Technical Field

[0001] This utility model relates to the field of electrical technology, specifically to a speaker cone and loudspeaker with a suspension edge. Background Technology

[0002] Traditional circular surrounds cause the speaker to vibrate in a piston-like motion, moving the body, voice coil, and spider up and down. High-power woofers have a wider R-ring surround. In the low-frequency range, when the diaphragm vibrates as a whole, the amplitude and phase of vibration are the same at all points on the diaphragm. As the frequency increases, the diaphragm undergoes segmentation, forming nodal points or nodal circles. During research and development, the applicant used laser holographic vibration analysis. The analysis showed that when the diaphragm transitions from whole-body vibration to segmented vibration, i.e., when the diaphragm forms its first nodal circle, a deep valley appears in the frequency response curve. This first nodal circle often appears near the surround. At this point, the surround has a large amplitude, but its vibration phase is opposite to that of the diaphragm. Therefore, the out-of-phase sound waves radiated by the diaphragm and surround cancel each other out, resulting in a valley in the frequency response and distortion. This distortion needs to be improved in today's market where consumer demands are increasingly high.

[0003] Therefore, there is an urgent need to develop a suspended cone that can reduce distortion at high power. Utility Model Content

[0004] This utility model aims to solve at least one of the above-mentioned technical problems to a certain extent.

[0005] Therefore, the first objective of this utility model is to provide a diaphragm with a suspension edge, which can reduce distortion at high power.

[0006] The second objective of this utility model is to provide a loudspeaker.

[0007] To achieve the above objectives, a first aspect of this utility model discloses a cone with a suspension edge, comprising: a cover 1 disposed in the middle, a plurality of suspension edges 2 disposed around the edges of the cover 1, and a mounting part 3 disposed at the outer edges of the plurality of suspension edges 1; wherein, the suspension edge 2 is high in the middle and low on the left and right sides, and the high peak in the middle has a steep slope inward, so that the entire suspension edge forms a mountain peak shape.

[0008] In addition, the diaphragm with suspension edge according to the above-described technical solution of this utility model may also have the following additional technical features:

[0009] Optionally, the number of suspended edges 2 is even, and they are symmetrical with respect to the center of the circle.

[0010] Optionally, the inner surface of the suspended edge 2 is a wavy surface, so that the inner surface of the suspended edge 2 forms multiple raised ridges and multiple recessed valleys.

[0011] Optionally, the protruding peak in the suspended edge 2 has symmetrically inclined slopes on both sides.

[0012] To achieve the above objectives, a second aspect of this utility model discloses a loudspeaker, comprising a T-shaped iron, a plurality of magnets mounted on the T-shaped iron, a washer mounted on the T-shaped iron and above the magnets, a voice coil disposed above the T-shaped iron, a frame disposed on the washer and mounted on the voice coil, a spider mounted on the voice coil and disposed on the frame, a paper holder disposed on the spider and with its lower end mounted on the voice coil, and a diaphragm with a suspension edge, as described in the first aspect of this utility model, disposed on the upper end of the paper holder and on the frame.

[0013] The beneficial effects of this utility model are as follows: 1. The upper and lower peaks and valleys of the suspension edge can effectively suppress the reverse pitch diameter or pitch circle formed when the speaker vibrates up and down, reducing distortion under high power; 2. The symmetrical peaks and valleys can further reduce distortion; 3. The small peaks and valleys of different sizes in the middle reduce unnecessary vibration and energy loss, and also improve the overall performance and sound quality of the speaker.

[0018] 1-Cover body, 2-Suspended edge, 3-Mounting part. Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or components / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following describes an embodiment of the present invention with a suspended cone, in conjunction with the accompanying drawings.

[0021] Figure 1 This is a cross-sectional view of a cone with a suspension edge provided in one embodiment of the present utility model; Figure 2This is an exploded view of a cone with a suspended edge provided in another embodiment of this utility model. (See diagram below.) Figure 1-2 As shown, the diaphragm with suspension includes: a cover 1 located in the middle, several suspensions 2 arranged around the edges of the cover 1, and mounting parts 3 located at the outer edges of the several suspensions 1; wherein, the suspensions 2 are high in the middle and low on the left and right sides, and the high peak in the middle has a steep slope inward, so that the entire suspension forms a mountain shape.

[0022] According to one embodiment of the present invention, the number of suspended edges 2 is even, and they are symmetrical with respect to the center of the circle.

[0023] Specifically, in the embodiments of this application, four suspension edges are used. These four suspension edges are arranged around the edge of the cover 1 to form a circle, with two suspension edges being symmetrical with respect to the center of the circle.

[0024] Traditional arc-shaped suspension edges exhibit relatively small vibrations near the cone's edge and the outer edge of the frame, while the amplitude in the center is larger, resulting in weak control and a tendency to produce distortion at low frequencies. In contrast, the embodiments of this application feature multiple mountain-shaped suspension edges, higher in the center and lower on both sides, forming a ring. This creates either convex or concave edges, effectively controlling the amplitude of high-power speaker vibrations, reducing unnecessary vibrations and energy loss, and improving the overall performance and sound quality of the speaker.

[0025] It should be noted that the "peak" mentioned here refers to the top of the overhang that bulges upwards.

[0026] According to this invention, the diaphragm with a suspension edge employs a mountain-shaped suspension edge. This special shape ensures that the suspension edge maintains the same radiation area regardless of whether the diaphragm advances or retracts, effectively reducing suspension edge radiation distortion and increasing linear offset. The mountain-shaped suspension edge design alters the geometry of the traditional circular ring suspension edge, adopting a centrally circling "mountain" shape. This design not only optimizes the speaker's vibration mode, reducing unnecessary vibration and energy loss, but also improves the overall performance and sound quality of the speaker.

[0027] According to one embodiment of the present invention, the inner surface of the suspended edge 2 is a wavy surface, which forms multiple raised ridges and multiple recessed valleys on the inner side of the suspended edge 2.

[0028] Specifically, the mountain-shaped overhang is improved according to the features of this embodiment, with a wave-like surface designed on the inward side to form a ridge that bulges inward and a valley that is recessed. At this time, the overhang can be called a "constant surface dynamic overhang".

[0029] The constant-surface dynamic surround features a unique "peak" and "ridge" shape design, replacing the traditional three-dimensional circular structure, aiming to achieve ultra-low distortion and high sound purity. The constant-surface dynamic surround design is not only technologically innovative but also enhances sound purity and analytical power through geometric optimization. In contrast, ordinary surrounds typically use a more traditional circular or ring-shaped design, lacking this geometric innovation and optimization. This design allows the speaker to more accurately reproduce the original signal when playing audio, reducing noise and distortion.

[0030] It should be noted that the "ridge" here refers to the part that protrudes inward, and needs to be distinguished from the "peak" that protrudes upward from the overhang.

[0031] According to one embodiment of the present invention, the protruding peak in the suspended edge 2 has symmetrically inclined slopes on both sides.

[0032] Specifically, symmetrical peaks and valleys can effectively suppress the reverse pitch diameter or pitch circle formed when the speaker vibrates up and down, reducing distortion at high power.

[0033] Based on the above embodiments, embodiments of this application also propose a loudspeaker. Figure 2 This is an exploded view of a horn with a suspended edge provided in another embodiment of this utility model; Figure 3 This is a cross-sectional view of a horn with a suspension edge provided in another embodiment of this utility model, as shown below. Figure 2-3 As shown, it includes: a T-shaped iron, several magnets mounted on the T-shaped iron, a washer mounted on the T-shaped iron and above the magnets, a voice coil disposed above the T-shaped iron, a frame disposed on the washer and mounted on the voice coil, a spider mounted on the voice coil and disposed on the frame, a paper holder disposed on the spider and with its lower end mounted on the voice coil, and a diaphragm with a suspension edge disposed on the upper end of the paper holder and on the frame, as described in the above embodiment.

[0034] According to this invention, the speaker cone employs a mountain-peak / ridge-shaped suspension edge. This special shape ensures that the suspension edge maintains the same radiation area regardless of whether the diaphragm advances or retracts, effectively reducing suspension edge radiation distortion and increasing linear offset. The mountain-peak-shaped suspension edge design alters the geometry of the traditional circular ring suspension edge, adopting a centrally circling "peak" shape. This design not only optimizes the speaker's vibration mode, reducing unnecessary vibration and energy loss, but also improves the overall performance and sound quality of the speaker.

[0035] The above embodiments are preferred implementations of this application. In addition, this application can be implemented in other ways. Any obvious substitutions without departing from the concept of this application are within the protection scope of this application.
