The radiator 100 for a speaker according to an embodiment of the present application will be described in detail below with reference to fig. 1 to 7.
As shown in fig. 1 to 4, an embodiment of the present application describes a radiator 100 for a speaker, where the radiator 100 includes a fixing portion 120 and a radiation portion 110 disposed at a middle portion, a shape of the radiation portion 110 matches a shape of a diaphragm 211 fixed to the speaker 210, and a surface of the radiation portion 110 opposite to the diaphragm 211 is a first radiation surface; the fixing portion 120 is fixed in a manner that the radiation portion 110 is opposite to the diaphragm 211, and a preset distance is formed between the first radiation surface and the diaphragm 211; the diaphragm 211 vibrates to generate sound waves, and the sound waves are transmitted through a sound field formed by the diaphragm 211 and the first radiation surface.
In this embodiment, a person skilled in the art may set the shape of the radiation part 110 according to the shape of the diaphragm 211, as long as the shape of the radiation part 110 matches the shape of the diaphragm 211 fixed to the speaker 210. For example, the diaphragm 211 has a concave structure, and correspondingly, the radiation portion 110 has a convex structure; alternatively, the diaphragm 211 has a convex structure, and the radiation portion 110 has a concave structure. Specifically, the diaphragm 211 has an inwardly concave hemispherical structure, and correspondingly, the radiation part 110 has a convex hemispherical structure; alternatively, the diaphragm 211 has a convex hemispherical structure, and the radiation part 110 has a concave hemispherical structure.
In this embodiment, as shown in fig. 2, the shape of the radiation portion 110 is matched with the shape of a diaphragm 211 fixed to the speaker 210, so that the fixing portion 120 is fixed in a manner that the radiation portion 110 and the diaphragm 211 are arranged opposite to each other, and a preset distance favorable for sound wave transmission can be formed between the first radiation surface and the diaphragm 211. The vibrating diaphragm 211 vibrates to generate sound waves, and the sound waves are transmitted through a sound field formed by the vibrating diaphragm 211 and the first radiation surface; since the sound waves are transmitted in the sound field with a preset distance and a good transmission effect, the loss of high-frequency energy of the loudspeaker 210 can be reduced, and the frequency response radiated by the loudspeaker is more balanced. It will be understood by those skilled in the art that the predetermined distance herein refers to a distance that facilitates transmission of sound waves. The preset distance may be a fixed value or a range value. It should be noted that, when the preset distance is a fixed value, the distances between each point on the diaphragm 211 and the first radiation surface are the same and are all preset distances; when the preset distance is a range value, the distances between each point on the diaphragm 211 and the first radiation surface are different, but are all within the range value. For example, the preset distance is H, and a person skilled in the art can determine a specific value of H according to the performance of the speaker 210. For another example, the preset distance is H1-H2, and the specific range of H1-H2 can be determined by those skilled in the art according to the performance of the speaker 210.
In some optional implementations of this embodiment, the first radiating structure further includes a plurality of protrusions disposed at a periphery of the radiating portion; the plurality of bulges are respectively connected with the radiating body, and the connection parts are smoothly arranged; the plurality of bulges radially extend from the radiating part to the outer edge; two adjacent side walls of two adjacent bulges in the plurality of bulges are connected, and the surfaces of the plurality of bulges opposite to the vibrating diaphragm form a second radiation surface; the vibrating diaphragm vibrates to generate sound waves, and the sound waves are transmitted to a sound field formed by the vibrating diaphragm and the second radiation surface through the sound field formed by the vibrating diaphragm and the first radiation surface.
The radiator 100 further includes a plurality of protrusions 112 disposed around the radiation portion 110, and the number and arrangement of the plurality of protrusions 112 may be set according to actual requirements. For example, the number of the plurality of protrusions 112 may be 3, 4, or 5. For another example, the plurality of protrusions 112 may be uniformly arranged or may be randomly arranged. It should be understood by those skilled in the art that when the number of the plurality of protrusions 112 is even and the plurality of protrusions 112 are uniformly arranged, the plurality of protrusions 112 are symmetrically arranged with respect to the radiation part 110. Fig. 1 and 3 exemplarily show that the number of the plurality of protrusions 112 is 6, and the 6 protrusions 112 are uniformly arranged and symmetrically arranged with respect to the radiation part 110; the plurality of protrusions 112 are symmetrically arranged, so that the appearance is more attractive, and the processing is convenient.
Here, the protrusion 112 extends radially from the radiating portion 110 to the outer edge to form a diffusion horn with the speaker 210, and the sound wave is diffused radially to the periphery of the radiator through the diffusion horn, so that the sound field distribution is more uniform; when the sound waves are transmitted through the plurality of protrusions 112, the sound waves can be transmitted to the corresponding direction through two side walls of the plurality of protrusions 112, so that the sound waves can be transmitted in a sound field distributed at an angle close to 360 degrees, and the sound field is distributed more uniformly; the peak-valley fluctuation of the frequency response of the loudspeaker 210 can be reduced, so that the frequency response of the loudspeaker 210 is smoother; the problem of axial acoustic modes of the loudspeaker 210 can also be solved.
Here, the shape of the cross section of the protrusion 112 may be set according to actual needs. As shown in fig. 3 and 4, it will be understood by those skilled in the art that the cross-section of the protrusions 112 is smoothly arranged in order to facilitate the propagation of the acoustic wave. Alternatively, in order to facilitate the sound waves to propagate in all directions in the space, the cross section of the protrusion 112 is in an inverted open shape, i.e. the opening is large and the top is small. For example, the cross-section of the protrusion 112 is an inverted U-shape. For another example, the cross section of the protrusion 112 is an inverted V shape, and a connection portion of two sidewalls of the protrusion 112 constituting the inverted V shape is smoothly disposed. For another example, the cross section of the protrusion 112 is convex curved; the curve may be a sine-like curve, a cosine-like curve, a parabola-like curve, or other types of curves.
Here, the height of the protrusion 112 may be a fixed value or a variable value. For example, the height of the protrusion 112 gradually increases as the protrusion 112 extends to the outer edge; thus, the sound waves of the speaker 210 are more favorably propagated to the periphery. The width of the protrusion 112 may be a fixed value or a variable value. For example, the width of the protrusion 112 gradually increases as the protrusion 112 extends to the outer edge; thus, the sound waves of the speaker 210 are more favorably propagated to the periphery. Fig. 1 exemplarily shows that the height of the protrusion 112 gradually increases as the protrusion 112 extends to the outer edge; and the width of the protrusion 112 gradually increases as the protrusion 112 extends to the outer edge; thus, the sound waves of the speaker 210 are more smoothly and uniformly propagated to the periphery. It should be noted that the height of the protrusion 112 refers to the depth of the highest point of the cross section of the protrusion 112, as shown in fig. 6 as H2; the width of the protrusion 112 refers to the opening width of the cross section of the protrusion 112, as shown by L2 in fig. 6. In some optional implementations of the present embodiment, the radiator 100 further includes a plurality of grooves 111 disposed at the periphery of the radiation portion 110; the grooves 111 are respectively connected with the radiator 100, and the connection positions are smoothly arranged; the grooves 111 radially extend from the radiating portion 110 to the outer edge, and two adjacent groove walls of two adjacent grooves 111 in the plurality of grooves 111 are connected; the surface of the plurality of grooves 111 opposite to the diaphragm 211 is configured as a second radiation surface; the vibration of the diaphragm 211 generates sound waves, and the sound waves are transmitted to the sound field formed by the diaphragm 211 and the second radiation surface through the sound field formed by the diaphragm 211 and the first radiation surface.
In this implementation manner, the radiator 100 further includes a plurality of grooves 111 disposed around the radiation portion 110, and the number and arrangement of the plurality of grooves 111 may be set according to actual needs. For example, the number of the plurality of grooves 111 may be 3, 4, or 5. For another example, the plurality of grooves 111 may be uniformly arranged, or may be randomly arranged. It should be understood by those skilled in the art that when the number of the plurality of grooves 111 is even and the grooves are uniformly arranged, the plurality of grooves 111 are symmetrically arranged with respect to the radiation part 110. Fig. 1 and 3 exemplarily show that the number of the plurality of grooves 111 is 6, and the 6 grooves 111 are uniformly arranged and symmetrically arranged with respect to the radiation part 110; a plurality of recesses 111 are arranged symmetrically, and are more pleasing to the eye, and convenient to process.
Here, the grooves 111 extend radially from the radiating portion 110 to the outer edge to form a diffusion horn with the speaker 210, and sound waves are diffused radially to the periphery of the radiator through the diffusion horn, so that the sound field distribution is more uniform; when the sound waves are transmitted through the grooves 111, the sound waves can be transmitted to the corresponding direction through two side walls of the grooves 111, so that the sound waves can be transmitted in a sound field distributed at an angle close to 360 degrees, and the sound field is distributed more uniformly; the peak-valley fluctuation of the frequency response of the loudspeaker 210 can be reduced, so that the frequency response of the loudspeaker 210 is smoother; the problem of axial acoustic modes of the loudspeaker 210 can also be solved.
Here, the shape of the cross section of the groove 111 may be set according to actual needs. As shown in fig. 3 and 4, it will be understood by those skilled in the art that the cross-section of the groove 111 is smoothly arranged in order to facilitate the transmission of the acoustic wave. Alternatively, in order to facilitate the sound waves to propagate in all directions in the space, the cross section of the groove 111 is in an open shape, i.e. the opening is large and the bottom is small. For example, the groove 111 has a U-shaped cross section. For another example, the cross section of the groove 111 is V-shaped, and the connection portion of the two sidewalls of the groove 111 constituting the V-shape is smoothly disposed. For another example, the cross section of the groove 111 is concave curved; the curve may be a sine-like curve, a cosine-like curve, a parabola-like curve, or other types of curves.
Here, the groove depth of the groove 111 may be a fixed value or a variable value. For example, the groove depth of the groove 111 gradually increases as the groove 111 extends to the outer edge; thus, the sound waves of the speaker 210 are more favorably propagated to the periphery. The groove width of the groove 111 may be a fixed value or a variable value. For example, the groove width of the groove 111 gradually increases as the groove 111 extends to the outer edge; thus, the sound waves of the speaker 210 are more favorably propagated to the periphery. Fig. 1 exemplarily shows that the groove depth of the groove 111 gradually increases as the groove 111 extends to the outer edge; the groove width of the groove 111 gradually increases as the groove 111 extends to the outer edge; thus, the sound waves of the speaker 210 are more smoothly and uniformly propagated to the periphery. It should be noted that the groove depth of the groove 111 refers to the depth of the lowest point of the cross section of the groove 111, as shown in fig. 5 as H1; the groove width of the groove 111 refers to an opening width of a cross section of the groove 111, as shown by L1 in fig. 5.
Here, two adjacent groove walls of two adjacent grooves 111 of the plurality of grooves 111 may be directly connected, or may be connected by another structure. It should be noted that, in order to facilitate the transmission of the sound wave, the connection between two adjacent groove walls of two adjacent grooves 111 in the plurality of grooves 111 is smoothly arranged. The following exemplarily lists that the adjacent two groove walls of the adjacent two grooves 111 of the plurality of grooves 111 are connected by other structures.

In this example, the protrusion 112 extends radially from the radiating portion to the outer edge, the groove 111 and the protrusion 112 together with the speaker 210 form an enlarged diffusing horn through which sound waves are diffused radially into the space, so that the sound field distribution is more uniform; when the sound waves are transmitted through the grooves 111 and the protrusions 112, the sound waves can be transmitted to the corresponding direction through the two side walls of the grooves 111 and the two side walls of the protrusions 112, so that the sound waves can be transmitted in a sound field distributed at an angle close to 360 degrees, and the sound field is distributed more uniformly. The peak-valley fluctuation of the frequency response of the loudspeaker 210 can be reduced, so that the frequency response of the loudspeaker 210 is smoother; the problem of axial acoustic modes of the loudspeaker 210 can also be solved.
Here, the shape of the cross section of the protrusion 112, the height of the protrusion 112, and the width of the protrusion 112 have been described above, respectively, and will not be described again.
Fig. 1 to 4 show exemplarily a concave curved segment of the groove 111 with a cross section of a periodic sine curve, and correspondingly a convex curved segment of the protrusion 112 with a cross section of a periodic sine curve; the plurality of grooves 111 and the plurality of protrusions 112 constitute a wave-shaped first radiation surface, so that the sound waves are more uniformly propagated in all directions.
Here, the protrusions 112 are disposed among the plurality of grooves 111, and thus, the number of the plurality of protrusions 112 is the same as that of the plurality of grooves 111, and the arrangement of the protrusions 112 is the same as that of the plurality of grooves 111.
