In addition, when the speaker is operating, the spring will not produce excessive up and down movement with the voice coil, which can prevent the spring from touching the components below. In addition, since the voice coil does not need to reserve a position for connecting the spring, the overall thickness of the speaker can be reduced, which is beneficial to the demand for thinness; or the overall thickness of the speaker can be maintained but the stroke length (excursion length) can be increased, which is beneficial to the low-frequency design of the speaker.

Description

Technical Field

[0001] The present invention relates to a speaker, and more particularly to a thin speaker. Background Art

[0002] Speakers are an important component for sound effects. Audio electrical energy makes the speaker's vibration plate (such as a paper cone or diaphragm) vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. There are many types of speakers, which can be divided into dynamic (electric), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (compression spring), ion and pneumatic speakers according to the transducer mechanism and structure. Electric speakers have the advantages of good electroacoustic performance, firm structure and low cost, and are widely used.

[0003] Generally speaking, the speaker's elastic wave (or damper) is located between the voice coil and the basin frame, for example, the inner edge of the elastic wave is glued to the voice coil. Under the electroacoustic principle, when the output voltage of the speaker is large, that is, when the power is required to be increased, the voice coil and the elastic wave will produce a large up and down movement, and then the elastic wave will touch the components below it. In order to solve the above-mentioned contact problem, although it can be overcome by moving the vibration plate upward and increasing the height of the voice coil, it will cause the overall thickness of the speaker to increase significantly, which is not conducive to the demand for thinness. Summary of the invention

[0004] A technical aspect of the present invention is a speaker.

[0005] According to one embodiment of the present invention, a speaker includes a basin frame and a vibration plate assembly. The vibration plate assembly is located on the basin frame. The vibration plate assembly has a vibration plate, a spring, a folding ring and a conductor. The inner edge and the outer edge of the spring are respectively connected to the bottom surface of the vibration plate and the basin frame, and the folding ring and the spring are arranged on the basin frame from top to bottom. The conductor is located on the bottom surface of the spring.

[0006] In one embodiment of the present invention, the fold ring and the spring are vertically arranged at the first connection position of the basin frame.

[0007] In one embodiment of the present invention, the fold ring and the spring are respectively disposed vertically at a first connection position and a second connection position of the basin frame.

[0008] In one embodiment of the present invention, the length direction of the conductor is the same as the radial direction of the wave damper, the bottom surfaces of the conductor and the wave damper are both wavy, and the bottom surfaces of the conductor and the wave damper are conformal.

[0009] In one embodiment of the present invention, the loudspeaker further comprises a voice coil, which is surrounded by a basin frame and has a wire, wherein the wire is electrically connected to an end of the conductor close to the voice coil, and an end of the conductor away from the voice coil passes through the basin frame.

[0010] In one embodiment of the present invention, the inner edge of the rim is connected to the upper side or the lower side of the outer edge of the vibration plate.

[0011] In one embodiment of the present invention, the loudspeaker further comprises a voice coil, wherein the top of the voice coil is connected to the bottom surface of the vibration plate, and the voice coil is covered by the central area of ​​the vibration plate.

[0012] In one embodiment of the present invention, the top of the voice coil is connected to the bottom surface of the vibration plate through a spring.

[0013] In one embodiment of the present invention, the vibration plate and the elastic wave are gradually lowered from the voice coil to the outer edge of the basin frame.

[0014] In one embodiment of the present invention, the loudspeaker further comprises a support ring, which is located between the outer edge of the folding ring and the basin frame.

[0015] In the above-mentioned embodiment of the present invention, since the inner edge of the speaker's elastic wave is connected to the bottom surface of the vibration plate, the folding ring and the elastic wave are arranged up and down on the basin frame, and the conductor is located on the bottom surface of the elastic wave, the vibration plate assembly can be pre-made, which can improve the convenience of assembling the speaker. In addition, when the speaker is operating, the elastic wave that is not connected to the voice coil will not produce excessive up and down movement with the voice coil, which can prevent the elastic wave from touching the components below and affecting the acoustic performance. In addition, since the voice coil does not need to reserve a position for connecting the elastic wave, the overall thickness of the speaker can be reduced, which is beneficial to the demand for thinness; or the overall thickness of the speaker can be maintained but the stroke length (excursion length) can be increased, which is beneficial to the low-frequency design of the speaker.

[0062] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some known and commonly used structures and elements will be depicted in a simple schematic manner in the drawings.

[0063] Figure 1 A three-dimensional diagram of a loudspeaker 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 See also Figure 1 and Figure 2, the speaker 100 includes a basin frame 110, a vibration plate assembly 120, a voice coil 140, a dust cover 150, a magnetic component 160 and a U-shaped iron 170. Among them, the vibration plate assembly 120 is located on the basin frame 110 with a supporting function. The U-shaped iron 170 and the voice coil 140 are installed at the bottom of the basin frame 110. In this embodiment, the U-shaped iron 170 can accommodate the voice coil 140 and the magnetic component 160, and the voice coil 140 is located between the U-shaped iron 170 and the magnetic component 160. The magnetic component 160 may include a first magnet 162, a washer 164 and a second magnet 166 stacked from bottom to top, but is not limited thereto.

[0064] The voice coil 140 is the driving unit of the speaker 100, and generally uses a very thin copper wire 142 wound in two layers on a tube body (i.e., a coil), which surrounds the magnetic component 160. When a current carrying sound information and changing at all times is passed through the voice coil 140, a magnetic field in different directions is generated at one moment and the next moment, and the voice coil 140 vibrates up and down according to the change in magnetic force, and then drives the vibration plate 121 to vibrate back and forth, so that the speaker 100 makes a sound.

[0065] In the present embodiment, the vibration plate assembly 120 has a vibration plate 121, a damper 124 and a conductor 127. Among them, the vibration plate 121 can be called a vibration membrane or drum paper, and the damper 124 can be called a damper or a centering support. The damper 124 is bonded to the vibration plate 121. Before assembling the speaker 100, the vibration plate assembly 120 can be pre-made to improve the convenience of assembling the speaker 100. The vibration plate 121 can be made of a lightweight and rigid material to avoid changes due to changes in ambient temperature and humidity. For example, the material of the vibration plate 121 can be natural fiber, artificial fiber, resin, rubber or metal, among which natural fibers can be selected from cotton, wood, wool, silk, etc., and artificial fibers can be selected from rayon, nylon, glass fiber, etc., but it is not used to limit the present invention.

[0066] In the following description, the internal structure of the speaker 100 after assembly will be described.

[0067] Figure 3 Draw Figure 1 A three-dimensional cross-sectional view of the loudspeaker 100 along line segment 3-3. Figure 2 and Figure 3 , the vibration plate 121 and the elastic wave 124 are both annular. The material of the elastic wave 124 can be cloth, but is not limited thereto. The vibration plate 121 has an inner edge 122a and an outer edge 122b opposite to each other, and the elastic wave 124 also has an inner edge 126a and an outer edge 126b opposite to each other. The inner edge 122a of the vibration plate 121 can be fixed on the voice coil 140. The inner edge 126a and the outer edge 126b of the elastic wave 121 are respectively connected to the bottom surface of the vibration plate 121 and the basin frame 110.

[0068] In addition, the speaker 100 may include a first adhesive G1. The first adhesive G1 may adhere the inner edge 126a of the elastic wave 124 to the bottom surface of the vibration plate 121. In the present embodiment, the inner edge 126a of the elastic wave 124 is adhered to the bottom surface of the vibration plate 121 near the inner edge 122a, but this is not intended to limit the present invention. For example, the inner edge 126a of the elastic wave 124 may be adhered to any position between the inner edge 122a and the outer edge 122b of the vibration plate 121, depending on design requirements.

[0069] Since the voice coil 140 is separated from the elastic wave 124, when the speaker 100 is operating, the elastic wave 124 that is not connected to the voice coil 140 will not generate excessive up and down (forward and backward) movement with the voice coil 140, which can prevent the elastic wave 124 from touching the components below (such as the U-shaped iron 170, the magnetic component 160 or the bottom of the basin frame 110) and affecting the acoustic performance and service life.

[0070] In addition, the stroke E1 is the distance between the inner edge 122a of the vibration plate 121 and the top of the U-shaped iron 170, and the stroke E2 is the distance between the bottom of the voice coil 140 and the bottom of the U-shaped iron 170. Since the voice coil 140 does not need to reserve a position for connecting the elastic wave 124, the height of the voice coil 140 can be reduced, thereby reducing the overall thickness of the speaker 100, which is beneficial to the demand for thinness; or the overall thickness of the speaker 100 is maintained but the lengths of the strokes E1 and E2 (excursion length) can be increased, which is beneficial to the low-frequency design of the speaker 100.

[0071] Figure 4 Draw Figure 2 A perspective view of the vibration plate assembly 120 as viewed from below. Figure 3 and Figure 4 , the conductor 127 is located on the bottom surface 125 of the elastic wave 124. The conductor 127 can be a strip of metal sheet. In this embodiment, the conductor 127 can be sewn to the bottom surface 125 of the elastic wave 124, so that the conductor 127 can be in direct contact with the elastic wave 124. The length direction of the conductor 127 in contact with the elastic wave 124 is the same as the radial direction of the elastic wave 124. The conductor 127 and the bottom surface 125 of the elastic wave 124 can both be wavy, so that the conductor 127 and the bottom surface 125 of the elastic wave 124 are conformal and can be closely arranged, saving space waste.

[0072] In this embodiment, the conductor 127 has two opposite ends 128a and 128b. One end 128a of the conductor 127 is close to the voice coil 140, and the other end 128b of the conductor 127 is away from the voice coil 140 and passes through the frame 110. One end 128b of the conductor 127 can be used to electrically connect to an external power source. In addition, the voice coil 140 is surrounded by the frame 110 and electrically connected to one end 128a of the conductor 127. For example, the voice coil 140 has a wire 142, and the wire 142 is electrically connected to one end 128a of the conductor 127 close to the voice coil 140. The wire 142 of the voice coil 140 can be fixed to one end 128a of the conductor 127 by welding to form a welding point 143.

[0073] Since the inner edge 126a of the elastic wave 124 of the speaker 100 is adhered to the bottom surface of the vibration plate 121 by the first adhesive G1, and the conductor 127 is located on the bottom surface 125 of the elastic wave 124, the vibration plate assembly 120 can be pre-made to enhance the assembly process. Figure 1 The convenience of 100 speakers.

[0074] In this embodiment, the vibration plate assembly 120 may further include a conductor 127a that is substantially symmetrical to the conductor 127. The conductor 127a is provided to balance the weight of the vibration plate assembly 120 rather than for conducting electricity. The shape, weight and material of the conductor 127a may be substantially the same as those of the conductor 127, but does not have the end 128b of the conductor 127 extending downward.

[0075] In the present embodiment, the vibration plate assembly 120 includes a folding ring 129. The folding ring 129 and the damper 124 are arranged vertically at the first connection position of the basin frame 110. The portion of the damper 124 close to the outer edge 126b is covered by the folding ring 129, that is, the outer edge 126b of the damper 124 overlaps with the outer edge 131b of the folding ring 129. The inner edge 131a of the folding ring 129 is connected to the outer edge 122b of the vibration plate 121. The inner edge 131a of the folding ring 129 is located at the lower side of the outer edge 122b of the vibration plate 121. However, in other embodiments, the inner edge 131a of the folding ring 129 may also be located at the upper side of the outer edge 122b of the vibration plate 121, depending on the design requirements. The outer edge 131b of the folding ring 129 is connected to the outer edge 126b of the damper 124. The vibration plate assembly 120 further includes a second adhesive G2. The second adhesive G2 can adhere the outer edge 126b of the damper 124 to the outer edge 131b of the folding ring 129. In addition, the vibration plate assembly 120 may further include a third adhesive G3. The third adhesive G3 can adhere the inner edge 131a of the folding ring 129 to the outer edge 122b of the vibration plate 121. In other embodiments, the folding ring 129 can be connected to the outer edge 122b of the vibration plate 121 by a heat pressing process. After the vibration plate assembly 120 is assembled, the outer edge 131b of the folding ring 129 and the outer edge 126b of the damper 124 can be set on the basin frame 110.

[0076] The fold ring 129 is an annular structure, and its cross-sectional shape can be annular, concave, convex, wavy, triangular, square, polygonal, or a combination thereof, depending on the design of the speaker 100. In this embodiment, the fold ring 129 is wavy, such as Figure 3 The material of the folding ring 129 can be rubber, foam or cloth, but it is not used to limit the present invention. The folding ring 129 and the elastic wave 124 can prevent the voice coil 140 and the vibration plate 121 from shaking horizontally (left and right) during operation, and provide damping and a certain restoring force.

[0077] It should be understood that the connection relationship, materials and functions of the components described above will not be repeated, and will be described first. In the following description, other forms of folding rings, elastic waves and vibration plates will be described.

In the present embodiment, the material of the folding ring 129a may be one-piece molded rubber, and its outer edge 131b has a greater thickness. In another embodiment, a support ring 180 may be provided between the outer edge 131b of the folding ring 129a and the outer edge 126b of the elastic wave 124 to raise the folding ring 129a or thin the outer edge 131b of the folding ring 129a.
