[0070] In order to fully understand the purpose, features and effects of the present invention, the present invention is further described in detail through the following specific embodiments and the accompanying drawings, as follows:
[0071] Please refer to Figure 1 and Figure 2 As shown in the figure, the present invention provides a double-sided vibration speaker 1, which includes: a magnetic return component 11, a first vibration component 12 and a second vibration component 13. The structure of the first vibration component 12 can be the same as that of the second vibration component 13, and the first vibration component 12 and the second vibration component 13 can be symmetrical with the magnetic return component 11 as the center.
[0072] Please refer to Figures 3 to 7 As shown in the figure, the magnetic return component 11 includes a main magnetic unit 111, a first magnetic conductive unit 112 and a second magnetic conductive unit 113. The main magnetic unit 111 has a main magnetic plate 1111 and two side magnetic conductive plates 1112. The main magnetic plate 1111 has at least one vent hole 1115. Each of the side magnetic conductive plates 1112 is arranged on both sides of the main magnetic plate 1111. The two sides of the main magnetic plate 1111 respectively have at least one assembly portion 1113. Each of the side magnetic conductive plates 1112 has at least one docking portion 1114 combined with the assembly portion 1113. The cross-section of the main magnetic unit 111 forms an H shape. The first magnetic conductive unit 112 is arranged on one side surface of the main magnetic plate 1111, and the second magnetic conductive unit 113 is arranged on the other side surface of the main magnetic plate 1111. The first magnetic conductive unit 111 has a first magnetic gap 114, and the second magnetic conductive unit 113 has a second magnetic gap 115.
[0073] The first vibration component 12 includes a first speaker seat 121, a first voice coil 122 and a first diaphragm 123. The first speaker seat 121 is configured on a side surface of the magnetic return component 11. The first voice coil 122 is movably configured in the first magnetic gap 114 and configured with the first diaphragm 123. The first diaphragm 123 is configured with the first speaker seat 121.
[0074] The second vibration component 13 includes a second speaker seat 131, a second voice coil 132 and a second diaphragm 133. The second speaker seat 131 is configured on the other side surface of the magnetic return component 11. The second voice coil 132 is movably configured in the second magnetic gap 115 and configured with the second diaphragm 133. The second diaphragm 133 is configured with the second speaker seat 131. The second speaker seat 131 and the first speaker seat 121 are combined with each other.
[0075] When the double-sided vibration speaker 1 of the present invention is used, it can be combined with a sound box (not shown in the figure), so that the first vibration component 12 and the second vibration component 13 are arranged on the two sides of the magnetic return component 11 in a vertically symmetrical manner, and share the magnetic return component 11, thereby allowing the first vibration component 12 and the second vibration component 13 to cooperate with the first magnetic conductive unit 112 and the second magnetic conductive unit 113 respectively, thereby forming two completely independent magnetic fields (such as the upper and lower magnetic fields). Figure 1 , Figure 2 and Figures 8 to 10 As shown), so as to drive the first diaphragm 123 and the second diaphragm 133 to vibrate through the first voice coil 122 and the second voice coil 132 through electromagnetic action.
[0076] When the first vibration component 12 and the second vibration component 13 move, after the first voice coil 122 and the second voice coil 132 receive the external electronic signal, the first diaphragm 123 and the second diaphragm 133 will move outward and inward at the same time. When the first diaphragm 123 and the second diaphragm 133 move outward, they push the air to vibrate and make sound. When the first diaphragm 123 and the second diaphragm 133 move inward, the two forces will offset each other through the vent 1115, so that the first vibration component 12 and the second vibration component 13 can achieve the shock absorption function, avoiding the force generated by the movement of the first diaphragm 123 and the second diaphragm 133, which drives the entire double-sided vibration speaker 1 to vibrate.
[0077] In this way, the double-sided vibration speaker 1 of the present invention can achieve the effect of two-way sound generation through the design of the double-sided diaphragm of the first diaphragm 123 and the second diaphragm 133 without changing the size, thereby improving the output volume and bass of the double-sided vibration speaker 1. More importantly, the simultaneous movement of the first vibration component 12 and the second vibration component 13 can offset the forces between each other, and further increase the shock-absorbing force of the double-sided vibration speaker 1, so as to prevent the first diaphragm 123 and the second diaphragm 133 from vibrating and causing the entire double-sided vibration speaker 1 to produce unnecessary vibrations, so as to avoid resonance and distortion. In addition, the double-sided vibration speaker 1 of the present invention can be designed in an H-shape through the main magnetic unit 111, so that the first vibration component 12 and the second vibration component 13 respectively cooperate with the first magnetic conductive unit 112 and the second magnetic conductive unit 113 to form two independent magnetic circuits above and below, and because they share a main magnetic plate 1111, two independent magnetic circuits above and below can be formed, so that the overall height of the double-sided vibration speaker 1 will not be increased. Furthermore, the main magnetic plate 1111 and each of the side magnetic plates 1112 are combined by each of the assembly parts 1113 and each of the docking parts 1114, so each of the assembly parts 1113 and each of the docking parts 1114 can be connected by laser welding. In addition to reducing the difficulty of forming the main magnetic unit 111 by metal stamping, it can also reduce the thickness of the double-sided vibration speaker 1 of the present invention.
[0078] In addition, in assembling the double-sided vibration speaker 1, it is only necessary to assemble the magnetic return component 11, the first vibration component 12 and the second vibration component 13 separately, and then directly combine and fix the three components of the magnetic return component 11, the first vibration component 12 and the second vibration component 13 to complete the assembly of the double-sided vibration speaker 1. That is, the double-sided vibration speaker 1 is disassembled into three semi-finished modules, and then assembled into a finished product at one time, so that the assembly quality is more stable and more efficient.
[0079] In addition to the above embodiments, in the embodiments of the present invention (such as Figures 1 to 7 As shown), the two sides of the main magnetic plate 1111 respectively have the vent holes 1115, each of the vent holes 1115 is in a notch shape, and the two sides of the first speaker seat 121 and the second speaker seat 131 respectively have at least one opening 10, and each of the openings is connected to each of the vent holes 1115.
[0080] In addition to the above embodiments, in the embodiments of the present invention (such as Figures 1 to 4 and Fig.10As shown in the figure), each side magnetic conductive plate 1112 has an air hole 1116, the aperture of each air hole 1116 is larger than the thickness of the main magnetic plate 1111, each air hole 1116 is arranged across one side surface and the other side surface of the main magnetic plate 1111, and the first speaker seat 121 and the second speaker seat 131 have at least one opening 10 on both sides, and each opening 10 is connected to each air hole 1116 and the air hole 1115.
[0081] In the embodiments of the present invention (such as Figures 1 to 4 As shown in the figure, the first speaker seat 121 and the second speaker seat 131 have at least one opening 10 on both sides, and each of the openings 10 is connected to the vent 1115. In this way, the double-sided vibration speaker 1 of the present invention can fully offset the airflow and force generated when the first diaphragm 123 and the second diaphragm 133 move through the cooperation of each of the vents 1115 and each of the openings 10, and discharge part of the gas outside the double-sided vibration speaker 1 to adjust the excess airflow inside the double-sided vibration speaker 1, thereby increasing the shock-absorbing force of the double-sided vibration speaker 1, preventing the first diaphragm 123 and the second diaphragm 133 from vibrating and causing the entire double-sided vibration speaker 1 to generate unnecessary vibrations, thereby achieving the purpose of shock-absorbing the double-sided vibration speaker 1, and avoiding noise and distortion caused by resonance.
[0082] In the embodiments of the present invention (such as Figures 1 to 7As shown in the figure, the two sides of the main magnetic plate 1111 are respectively provided with air holes 1115, each of which is in the shape of a notch, and each of the side magnetic conductive plates 1112 has an air hole 1116 connected to each of the air holes 1115. Among them, the main magnetic unit 111 is made of metal magnetic conductive material (such as low carbon steel), so it is difficult to directly form an H shape through a conventional metal stamping process. In order to realize the main magnetic unit 111 with an H-shaped cross-section, the main magnetic plate 1111 is planar and the main magnetic plate 1111 has four protrusions after the two notch-shaped air holes 1115 are set. Each of the side magnetic conductive plates 1112 can be provided with two through holes to correspond to the protrusions so as to be combined with the main magnetic plate 1111. In addition, the first speaker seat 121 and the second speaker seat 131 have at least one opening 10 on both sides, and each of the openings 10 is connected to each of the air holes 1116. Furthermore, the long side of the double-sided vibration speaker 1 may be provided with a plurality of openings 10, or the short side of the double-sided vibration speaker 1 may be provided with a single opening 10, or the long side of the double-sided vibration speaker 1 may be provided with a plurality of openings 10 and the short side of the double-sided vibration speaker 1 may be provided with a single opening 10. Thus, the double-sided vibration speaker 1 of the present invention can fully offset the airflow and the force generated when the first diaphragm 123 and the second diaphragm 133 move through the cooperation of the vent holes 1115, the vent holes 1116 and the openings 10, and discharge part of the gas outside the double-sided vibration speaker 1 to adjust the excess airflow inside the double-sided vibration speaker 1, thereby increasing the shock-absorbing force of the double-sided vibration speaker 1, preventing the first diaphragm 123 and the second diaphragm 133 from vibrating and causing the entire double-sided vibration speaker 1 to generate unnecessary vibrations, thereby achieving the purpose of shock-absorbing the double-sided vibration speaker 1, and avoiding noise and distortion caused by resonance.
[0083] In the embodiments of the present invention (such as Figures 2 to 7 As shown in the figure, the two sides of the two ends of the main magnetic plate 1111 respectively have the connecting parts 1113, and each of the side magnetic conductive plates 1112 has two docking parts 1114 combined with each of the connecting parts 1113. After the main magnetic plate 1111 is penetrated by the docking parts 1114 of each of the side magnetic conductive plates 1112 with each of the connecting parts 1113, the connection between them is completed by laser welding to ensure that the main magnetic unit 111 and each of the side magnetic conductive plates 1112 are not easy to fall off, so that the main magnetic unit 111 has better operation stability.
[0084] In the embodiments of the present invention (such as Figures 2 to 7 and Fig. 9As shown in FIG. 1 , each of the assembly parts 1113 has a stopper 1118 on both sides, and each of the assembly parts 1113 exceeds the stopper 1118. After each of the assembly parts 1113 and each of the docking parts 1114 are combined, each of the stopper 1118 can stop each of the side magnetic conductive plates 1112, so that each of the assembly parts 1113 does not exceed each of the docking parts 1114, that is, each of the assembly parts 1113 does not exceed the outer wall surface of each of the side magnetic conductive plates 1112. In this way, there is space to accommodate solder balls (not shown) when the main magnetic plate 1111 and the side magnetic plates 1112 are laser welded. Therefore, even if the solder balls protrude from the wall surface of the side magnetic plates 1112, the space area 20 between the side magnetic plates 1112 and the first speaker seat 121 and the second speaker seat 131 will not interfere with each other when the magnetic return assembly 11 is assembled on the first speaker seat 121 and the second speaker seat 131. In addition, since the assembly portions 1113 do not exceed the outer wall surface of the side magnetic plates 1112, the magnetic circuit of the magnetic return assembly 11 can follow the predetermined magnetic path to avoid the situation of magnetic force divergence.
[0085] In the embodiments of the present invention (such as Figures 2 to 7 As shown in FIG. 1 , each of the connecting portions 1114 is a through hole. Thus, the double-sided vibration speaker 1 of the present invention can be laser welded from the outer side of each of the side magnetic conductive plates 1112 to each of the connecting portions 1113 and the connecting portions 1114 .
[0086] In the embodiments of the present invention (such as Figures 2 to 7 As shown in the figure), the first magnetic conductive unit 112 has a first magnet 1121 and a first magnetic conductive plate 1122, the second magnetic conductive unit 113 has a second magnet 1131 and a second magnetic conductive plate 1132, the first magnet 1121 is arranged on one side surface of the main magnetic plate 1111, the first magnetic conductive plate 1122 is arranged on the first magnet 1121, the second magnet 1131 is arranged on the other side surface of the main magnetic plate 1111, and the second magnetic conductive plate 1132 is arranged on the second magnet 1131. In this way, the double-sided vibration speaker 1 of the present invention allows the first vibration component 12 and the second vibration component 13 to cooperate with the first magnetic conductive unit 112 and the second magnetic conductive unit 113 respectively, thereby forming two completely independent magnetic fields (as shown in the figure). Figure 8 and Fig. 9 As shown), so as to drive the first diaphragm 123 and the second diaphragm 133 to vibrate through the first voice coil 122 and the second voice coil 132 through electromagnetic action.
[0087] In the embodiments of the present invention (such as Figures 1 to 4 and Figures 8 to 10As shown in the figure, at least one first opening portion 1211 is respectively provided on both sides of the first speaker seat 121, and at least one second opening portion 1311 is respectively provided on both sides of the second speaker seat 131, and each of the first opening portions 1211 and each of the second opening portions 1311 correspond to each other to form the opening 10; in this embodiment, three first opening portions 1211 are respectively provided on both sides of the first speaker seat 121, and three second opening portions 1311 are respectively provided on both sides of the second speaker seat 131, so that the two sides of the double-sided vibration speaker 1 have three openings 10, and one of the openings 10 on both sides corresponds to each of the air holes 1116. In this way, the double-sided vibration speaker 1 of the present invention can fully offset the airflow and force generated when the first diaphragm 123 and the second diaphragm 133 move through the cooperation of each of the openings 10, each of the vents 1115 and each of the air holes 1116, and discharge part of the gas to the outside of the double-sided vibration speaker 1 to adjust the excess airflow inside the double-sided vibration speaker 1, thereby increasing the shock-absorbing force of the double-sided vibration speaker 1 and preventing the first diaphragm 123 and the second diaphragm 133 from vibrating and causing unnecessary vibrations in the entire double-sided vibration speaker 1, thereby achieving the purpose of shock-absorbing the double-sided vibration speaker 1 and avoiding noise and distortion caused by resonance.
[0088] In the embodiments of the present invention (such as Figures 2 to 7 As shown in the figure, each of the two ends of the side magnetic conductive plate 1112 has a connecting portion 1117, and the first speaker seat 121 and the second speaker seat 131 are correspondingly assembled on the connecting portion 1117, so that the second speaker seat 131 and the first speaker seat 121 are combined with each other, and a space area 20 is formed between the outer side surface of each side magnetic conductive plate 1112 and the first speaker seat 121 and the second speaker seat 131, and the space area 20 connects each of the openings 10 and each of the air holes 1116. In this way, the double-sided vibration speaker 1 of the present invention can fully offset the airflow and force generated when the first diaphragm 123 and the second diaphragm 133 move through the cooperation of each of the openings 10, each of the vents 1115 and each of the air holes 1116, and discharge part of the gas to the outside of the double-sided vibration speaker 1 so that excess airflow will not accumulate in the space area 20, so as to adjust the excess airflow inside the double-sided vibration speaker 1 and increase the shock-absorbing force of the double-sided vibration speaker 1, so as to prevent the first diaphragm 123 and the second diaphragm 133 from vibrating and causing unnecessary vibration of the entire double-sided vibration speaker 1, thereby achieving the purpose of shock-absorbing the double-sided vibration speaker 1 and avoiding noise and distortion caused by resonance.
