Description

Wave-shaped suspension structure and vibration unit

Technical field

The present invention relates to a sound effect device, and more particularly to a wave-shaped suspension structure of a speaker vibration unit.

Background technique

An existing sound device, such as a speaker, generally includes a speaker frame, a diaphragm supported by the speaker frame, a voice coil coupled to the diaphragm, and a magnetic return unit for electromagnetically sensing with the voice coil, thereby The diaphragm is driven to vibrate to reproduce the sound. In particular, the diaphragm is mounted at an opening of the speaker frame, wherein when the voice coil is electromagnetically induced to reciprocate, the diaphragm vibration is driven accordingly. However, the vibration direction of the diaphragm is uncontrolled, so that the diaphragm cannot reproduce a good sound quality. In order to obtain a better sound quality, the diaphragm should reciprocate in only one direction with a uniform amplitude. For example, when the diaphragm is horizontally placed, the diaphragm should reciprocate only in the vertical (upward and downward) directions, and the upward displacement of the diaphragm should be with the diaphragm The downward displacement is the same.

That is to say, the existing diaphragm cannot be moved only in the axial direction thereof, but the offset sway occurs when moving along the axial direction, resulting in the sound being unclean. As shown in Fig. 1, a typical speaker vibration unit can be used as a vibration system of a speaker to connect to a voice coil to generate sound in response to an input of an audio signal, or it can also function as a passive vibration unit via air pressure. The changes are driven by other speaker systems and the vibrations produce an auxiliary sound effect. As shown in the figure, the vibration unit of a typical speaker in the prior art includes an intermediate vibration block 1, a suspension 2 located around the vibration block 1, and an outer frame 3. The suspension 2 is arched and coaxial with the vibration block 1. However, in this conventional vibration unit, the suspension 2 does not function to restrict the vibration direction of the vibration block 1 in its axial direction during one vibration period. Because the vibrating block 1 moves in a deviation from the axial direction, the suspension 2 itself does not generate a corresponding pulling force to prevent the displacement of the vibrating block 1, but the biasing force of the vibrating block 1 is transmitted to the connection of the suspension 2 to the outer frame 3. It was relieved at the time. That is to say, the suspension 2 does not effectively prevent the offset of the vibration block 1 in time.

An existing solution, as shown in Figures 2 and 3, is provided between the suspension 2 and the outer frame 3. A plurality of reinforcing ribs 4 are provided, which serve to position to prevent the vibration block 1 from shifting in the axial direction. That is to say, when an offset is generated, the biasing force is transmitted to these reinforcing ribs 4, and is cancelled in time. However, as shown in Fig. 3, in a section of such a vibrating unit, it can be seen that the reinforcing rib 4 is in line contact with the vibrating block 1 and the outer frame 3, so that when the vibrating block 1 is axially When moving, the pulling force of the axial movement is also quickly transmitted to the reinforcing ribs 4, and is further transmitted to the outer frame 3, so that the axial movement of the vibrating block 1 is also affected by the reinforcing ribs 4. That is to say, although the reinforcing rib 4 plays a role of preventing the offset, the displacement of the vibrating block 1 in the axial direction, that is, the stroke of the vibrating unit is also reduced, which affects the stroke of the entire vibrating unit. To make the sound quality not good, especially the bass sound quality.

In addition, in order to obtain better sound quality, especially the bass effect, the stroke of the vibration unit or diaphragm needs to be as large as possible, and the solution in the conventional sound device is usually to make a large-sized vibration unit or diaphragm size, thereby Make the existing sound device not small enough. For many compact products that contain sound effects, such as flat-panel TVs, mobile phones, and laptops, the sound device that you want to use is as flat and thin as possible, so that its compact products can maintain unique designs. And shape. Large sound effects are not suitable for designing in these compact products.

detailed description

The following description is presented to disclose the invention to enable those skilled in the art to practice the invention. The preferred embodiments in the following description are by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention as defined in the following description may be applied to other embodiments, modifications, improvements, equivalents, and other embodiments without departing from the spirit and scope of the invention.

3 to 5B is a vibration unit 100 according to a first preferred embodiment of the present invention, comprising a vibrating member 10 located in the middle, a suspension structure around the vibrating member 10, and a hanging structure A resilient overhang 20 is included, as well as a frame 30 positioned about the resilient overhang 20. That is, the elastic suspension 20 is made of an elastic material and extends between the vibrating member 10 and the frame 30 to restrict vibration of the vibrating member. The vibrating element 10 can be circular, elliptical, square or other polygonal shape. In this preferred embodiment, the vibrating element 10 is elliptical. The elastic suspension edge 20 also correspondingly forms a substantially elliptical shape around the vibrating element 10. The frame 30 can be of various shapes, and the invention is not limited in this regard.

In this preferred embodiment, the vibration unit 100 further includes a plurality of limiting ribs 40 extending between the vibrating member 10 and the frame 30 such that the vibrating member 10 A structure of high and low undulations is formed between the frame 30 and the frame 30. The limiting rib 40 is used for limiting action to prevent displacement of the vibrating element 10 from its central axis. More specifically, when the vibrating member 10 is to be offset from its central axis, the corresponding limiting rib 40 generates a reverse pulling force to cancel the offset causing the vibrating member 10 to shift. force. It is worth mentioning that the limiting rib 40 may extend in a direction perpendicular to the outer peripheral surface of the corresponding vibrating element 10 and the inner peripheral surface of the corresponding frame 30, as shown in FIG. It may be arranged along the radial direction of the vibration unit 10 or obliquely. This arrangement can produce corresponding pulling forces along these directions, effectively preventing the vibrating elements from shifting in these directions.

It is worth mentioning that these limiting ribs 40 can be evenly arranged around the vibrating element 10 and can be arranged symmetrically with respect to the center of the vibrating element 10. As an example, as shown in FIG. 3, these limiting ribs 40 include a left side limiting rib 401 and a right side limiting rib 402. When the vibration unit 100 is placed up and down and operates normally, the vibrating element 10 moves up and down along the axial direction, and when the vibrating element 10 wants to be shifted to the left, the right side limiting rib 402 is immediately received. Reverse pull to the right, Thereby the vibrating element 10 is prevented from shifting further to the left. On the contrary, when the vibrating member 10 is intended to be shifted to the right, it is immediately subjected to the reverse pulling force of the left limiting rib 401 to the left, thereby preventing the vibrating member 10 from being further shifted to the right. Thus, the elastic suspension 20 and the limiting rib 40 can effectively restrict the vibration direction of the vibrating member 10 in the up and down direction along the axial direction.

The elastic suspension 20 may have the structure shown in FIG. 1 disposed coaxially with the vibrating member 10, and along the radial direction of the vibrating member 10, the cross section thereof is wavy or arched. As shown in FIG. 5B, an annular ridge can be formed along the central axis of the vibrating member 10. It is to be noted that each of the limiting ribs 40 is convexly disposed from the elastic suspension edge 20 to form a high and low relief structure in the circumferential direction of the vibrating member 10. That is, the "wavy shape" of the present invention may not be a strict wave shape similar to water, but a wrinkle structure or a corrugated paper structure may be formed around the vibrating member 10.

As shown in FIG. 3, a plurality of the limiting ribs 40 substantially divide the elastic suspension edge 20 into a plurality of hanging sections 201. The number of the limiting ribs 40 is not limited, and it can be adjusted according to different needs. In the example shown in FIG. 3, eight of said limit ribs 40 divide said elastic overhang 20 into eight of said overhang sections 201. Each of the limiting ribs 40 is also made of an elastic material, which may be made of the same elastic material as the elastic hanging edge 20, or may be made of a different elastic material. When the limiting rib 40 and the elastic suspension 20 are made of the same material, a plurality of the limiting ribs 40 and the elastic suspension 20 may be integrally formed. That is, a predetermined elastic material can be injected using a molding die in one injection molding step, thereby simultaneously producing a combination with a plurality of the stopper ribs 40 and the elastic suspension edge 20. It is worth mentioning that the predetermined elastic material may also be coated on the vibrating member 10 during the molding process to form an elastic coating layer 12. That is, the vibrating member 10 may include an inner vibration weighting block 11 and an outer elastic coating layer 12. It is worth mentioning that the elastic suspension 20 and the limiting rib 40 can also be bonded to the frame 30 and the vibrating element 10 by glue in a conventional manner.

It is worth mentioning that, as shown in FIG. 5B, the arched structure of the elastic suspension 20 can form an annular groove 202. Each of the limiting ribs 40 may be disposed outwardly on both sides of the elastic suspension 20 or only on one side of the elastic suspension 10 . In this preferred embodiment, each of the limiting ribs 40 and the annular groove 202 are located on both sides of the elastic suspension edge 20, that is, each of the limiting ribs 40 does not extend into the ring. The groove 202 extends only on one side of the elastic suspension 10, as shown in FIG. 5B, which protrudes convexly on the upper side of the elastic suspension 10. A groove 203 is formed between the two adjacent limiting ribs 40, so that the elastic suspension 20 and the limiting rib 40 are at the vibrating element. A structure of high and low undulations is formed around the periphery of 10.

As shown in FIG. 3 and FIG. 5A, each of the limiting ribs 40 may have a triangular shape, a trapezoidal shape, a rhombus shape, or the like, so as to stably position the connection and prevent the vibration element 10 from being obstructed. Axial movement. More specifically, in the examples shown in FIGS. 3 and 5A, each of the limiting ribs 40 has a sheet shape and a triangular cross section. The triangular limiting rib 40 may be connected to the vibrating element 10 through a bottom edge of the triangle, a vertex of the triangle is connected to the frame 30, or may be connected to the frame 30 through a bottom edge of the triangle, triangular A vertex is connected to the vibrating element 10.

Preferably, each of the limiting ribs 40 includes a vibrating element connecting end 41 and a frame connecting end 42. The vibrating element connecting end 41 is in line connection with the outer peripheral surface 101 of the vibrating element 10, that is, the triangular bottom edge of the limiting rib 40 is in contact with and connected to the outer peripheral surface 101 of the vibrating element 10. . The frame connecting end 42 is point-connected to the inner peripheral surface 301 of the frame 30, that is, the apex of the triangle of the limiting rib 40 is in contact with and connected to the inner peripheral surface 301 of the frame 30. It is worth mentioning that the triangle formed by the cross section of the limiting rib 40 may be any triangular shape, such as a right triangle, an isosceles triangle, and may form an equilateral triangle. It should be noted that each side of the triangle here may be a straight line or a curve. In the example shown in FIG. 5A, the portion of each of the limiting ribs 40 connected to the elastic suspension 20 may be It is curved.

It is worth mentioning that this design makes the connection strength of the limiting rib 40 and the vibration element 10 greater than the connection strength with the frame 30. Thereby, while preventing the vibration element 10 from being displaced, the thrust for pushing the vibration element 10 to move in the axial direction is not transmitted to the frame 30 quickly, and the stroke of the vibration element 10 is the axis. The displacement is not greatly affected. That is, the pulling force applied by the frame 30 to the limiting rib 40 to pull the vibrating element 10 back to its original position is not transmitted to the vibrating element 10 quickly, but the vibrating element 10 is made as far as possible. The maximum axial displacement is reached. That is to say, when the limiting rib 40 is not allowed to start axial displacement from the intermediate initial position, it is immediately subjected to the restoring force from the frame 30 to shorten the axial displacement.

That is, as shown in FIGS. 2A and 2B, the reinforcing rib 4 is linearly connected to the vibration block 1 and the outer frame 3, and has a substantially rectangular cross section such that both ends of the reinforcing rib 4 pass through the vibration block 1 and the outer frame 3. The connection structure is the same so as to have the same connection strength. Thus, the pulling force of the pulling back vibration block 1 by the outer frame 3 and the reinforcing ribs 4 can be applied to the vibration block 1 in real time, and the axial displacement of the vibration block 1 is also affected. That is to say, although the reinforcing rib 4 can function to reduce the offset of the vibrating block 1, it has a serious adverse effect on the stroke of the vibrating block 1. The present invention enables each of the limit ribs One end of 40 forms a point connection with the frame 30, and the other end forms a line connection with the vibrating element 10, which can prevent the shaking and shifting of the vibrating element 10, and can not affect the vibrating element 10. Axial displacement.

6 to 11B are a vibration unit 100A according to a second preferred embodiment of the present invention, comprising a vibrating member 10A surrounding a wave-shaped suspension structure around the vibration member 10A, the wave-shaped suspension structure The elastic overhang 20A is included, as well as the frame 30A. The elastic suspension 20A extends between the vibrating element 10A and the frame 30A. In this embodiment, the elastic suspension 20A forms a wavy structure in the circumferential direction around the vibrating member 10A.

Specifically, the elastic suspension 20A includes a plurality of waveform stopper segments 21A disposed along the circumferential direction such that the plurality of the waveform stopper segments 21A form a wave-shaped structure around the vibration element 10A. On the other hand, the overhang 2 in Fig. 1 is formed with an arched or wavy structure only in the radial direction of the vibrating block 1, so that the offset action of the vibrating member 10A cannot be effectively prevented.

The plurality of waveform limit segments 21A of the present invention are used for limiting action to prevent displacement of the vibrating member 10A from its central axis X. More specifically, when the vibrating element 10A is to be offset from its central axis X to produce an offset in a certain direction, the corresponding waveform limit segment 21A generates a pulling force in the opposite direction to cancel the vibration element 10A. An offset force that produces an offset. It is worth mentioning that these waveform limiting segments 21A can be evenly arranged around the vibrating element 10A and can be arranged symmetrically with respect to the center of the vibrating element 10A.

As an example, as shown in FIG. 6, a plurality of the waveform limit segments 21A include a left waveform limit segment 21A and a right waveform limit segment 21A. When the vibration unit 100A is placed up and down and operates normally, the vibrating member 10A moves up and down along the X-axis, and when the vibrating member 10A wants to shift leftward along the Y-axis shown in FIG. 6, Immediately, the reverse pulling force of the right waveform limit segment 21A to the right is prevented, thereby preventing the vibrating element 10A from being further shifted to the left.

Element 10A is further offset to the right. Thus, the elastic suspension 20A can effectively restrict the vibration direction of the vibrating member 10A in the up and down direction along the X axis.

Each of the waveform limit segments 21A includes a vibrating element connection end 211A and a frame connection end 212A.

connection sites

2121A, 2122A, and 2123A extending from the lower

side connection sites

The stroke of the element 10A, i.e., the axial displacement, is not greatly affected. That is, the pulling force applied by the frame 30A to the waveform limiting section 21A to pull the vibrating element 10A back to its original position is not quickly transmitted to the vibrating element 10, but the vibrating element is made as far as possible. 10A reaches the maximum axial displacement.

It will be appreciated by those skilled in the art that the manner of connection can be reversed. That is, the connection structure of the outer edge of the waveform limiting segment 21A and the frame 30A is triangular, and the connection between the outer edge and the vibrating element 10A is an arc in the same plane, instead of a high and low undulation.

In addition, a groove 203A is formed between the adjacent two of the waveform limiting segments 21A, thereby forming a series of mutually spaced grooves 203A along the circumferential direction of the vibrating member 10, thereby forming a wave. Shape structure.
