[0058] Please refer to Figures 1 to 6 As shown in the figure, the present invention provides a double-sided speaker 1, which includes: a magnetic conductive component 10, a first speaker 11 and a second speaker 12.

[0060] The second speaker 12 is disposed on the other side surface of the magnetic conductive component 10. The second speaker 12 includes a second magnetic return component 121, a second speaker seat 122, a second voice coil 123 and a second diaphragm 124. The second magnetic return component 121 is located on the other side surface of the magnetic conductive component 10. The second magnetic return component 121 has a second magnetic gap 125.

The second speaker seat 122 and the first speaker seat 112 are combined with each other.

[0061] In an embodiment of the present invention, the first magnetic return component 111 includes a first magnetic conductive group 1111 and a first magnet group 1112, the first magnetic conductive group 1111 is stacked on the first magnet group 1112, and the first magnet group 1112 is arranged on one side surface of the magnetic conductive component 10, wherein the first magnetic conductive group 1111 has a first main magnetic plate 11111 and two first secondary magnetic conductive plates 11112, and the first secondary magnetic conductive plates 11112 are respectively located on both sides of the first main magnetic plate 11111, and the first magnet group 1112 has a first main magnet 11121 and two first secondary magnets 11122, and the first secondary magnets 11122 are respectively located on both sides of the first main magnet 11121.

[0062] In an embodiment of the present invention, the second magnetic return component 121 includes a second magnetic conductive group 1211 and a second magnet group 1212, the second magnetic conductive group 1211 is stacked on the second magnet group 1212, and the second magnet group 1212 is arranged on the other side surface of the magnetic conductive component 10, wherein the second magnetic conductive group 1211 has a second main magnetic conductive plate 12111 and two second secondary magnetic conductive plates 12112, and the second secondary magnetic conductive plates 12112 are respectively located on both sides of the second main magnetic conductive plate 12111, and the second magnet group 1212 has a second main magnet 12121 and two second secondary magnets 12122, and the second secondary magnets 12122 are respectively located on both sides of the second main magnet 12121.

[0063] When the double-sided speaker 1 of the present invention is used, it can be combined with a sound box (not shown), so that the first speaker 11 and the second speaker 12 are arranged on the two sides of the magnetic conductive component 10 in a vertically symmetrical manner, and share the magnetic conductive component 10, so that the first magnetic return component 111 of the first speaker 11 and the second magnetic return component 121 of the second speaker 12 can form two completely independent magnetic fields (such as Figure 4 , Figure 5A and Figure 5B As shown), so as to drive the first diaphragm 114 and the second diaphragm 124 to vibrate through the first voice coil 113 and the second voice coil 123 through electromagnetic action.

[0064] The vibration mode of the first speaker 11 and the second speaker 12 during movement is as follows Figure 6 As shown, after the first voice coil 113 and the second voice coil 123 receive the external input electronic signal, the first diaphragm 114 and the second diaphragm 124 will move outward at the same time (as shown in FIG. Figure 6 direction of the arrow in part (a)) and inward movement at the same time (such as Figure 6 When the first diaphragm 114 and the second diaphragm 124 move outward, they push the air to vibrate and make sound, and when the first diaphragm 114 and the second diaphragm 124 move inward, the two forces offset each other, so that the first speaker 11 and the second speaker 12 can achieve the function of shock absorption, avoiding the force generated by the movement of the first diaphragm 114 and the second diaphragm 124 from driving the entire double-sided speaker 1 to vibrate.

[0065] In this way, the double-sided speaker 1 of the present invention can achieve a two-way sound effect through the design of the double-sided diaphragms of the first diaphragm 114 and the second diaphragm 124 without changing its size, thereby improving the output volume and bass of the double-sided speaker 1. More importantly, due to the simultaneous movement of the first speaker 11 and the second speaker 12, the forces acting on each other can be offset, and the vibration suppression capability of the double-sided speaker 1 can be further increased, so as to prevent the first diaphragm 114 and the second diaphragm 124 from vibrating and causing the entire double-sided speaker 1 to generate unnecessary vibrations, thereby avoiding resonance to generate noise and distortion.

[0066] In the embodiments of the present invention (such as Figure 2 and Figure 3 As shown in FIG. 1 , the magnetic conductive component 10 has a plurality of openings 101 connected to the two side surfaces, and the first magnetic gap 115 and the second magnetic gap 125 correspond to the openings 101. In this way, the forces generated by the movement of the first diaphragm 114 and the second diaphragm 124 can be more fully contacted and offset through the openings 101, thereby increasing the vibration suppression capability of the double-sided speaker 1, preventing the first diaphragm 114 and the second diaphragm 124 from vibrating and causing the entire double-sided speaker 1 to generate unnecessary vibrations, thereby avoiding resonance and generating noise and distortion.

[0067] In the embodiments of the present invention (such as Figure 2 and Figure 3As shown in FIG. 1 , the two sides of the magnetic conductive component 10 are provided with notches 102, respectively, and each notch 102 is located between two openings 101. In this way, the cooperation of the notches 102 or the cooperation of the opening 101 and the notches 102 can fully offset the force and airflow generated when the first diaphragm 114 and the second diaphragm 124 move, thereby increasing the vibration suppression capability of the double-sided speaker 1, preventing the first diaphragm 114 and the second diaphragm 124 from vibrating and causing the entire double-sided speaker 1 to generate unnecessary vibrations, thereby avoiding resonance and generating noise and distortion.

[0068] In the embodiments of the present invention (such as Figure 2 and Figure 3 As shown in FIG. 1 , the two ends of the magnetic conductive component 10 respectively have a first connecting portion 103 and a second connecting portion 104, each of the first connecting portions 103 is assembled with the first speaker seat 112, and each of the second connecting portions 104 is assembled with the second speaker seat 122. In this way, the first speaker seat 112 of the first speaker 11 and the second speaker seat 122 of the second speaker 12 can be firmly combined with the magnetic conductive component 10 to maintain the stability of the first speaker 11 and the second speaker 12 when they move on the two side surfaces of the magnetic conductive component 10. In addition, the magnetic conductive component 10 can cooperate with the first magnetic return component 111 and the second magnetic return component 121 to form magnetic lines of force in addition to being respectively connected to the first speaker seat 112 and the second speaker seat 122 through each of the first connecting parts 103 and the second connecting parts 104. Since both sides of the short axis of the first magnetic return component 111 have cooperated with the first secondary magnetic conductive plate 11112 and the first secondary magnet 11122 to form a complete magnetic line of force, and both sides of the short axis of the second magnetic return component 121 have cooperated with the second secondary magnetic conductive plate 12112 and the second secondary magnet 12122 to form a complete magnetic line of force, it is not necessary to set a retaining wall or a retaining structure (such as Figure 5A As shown); and the two sides of the long axis of the magnetic conductive component 10 are respectively passed through each of the first connecting parts 103 and each of the second connecting parts 104 to form an upward and downward retaining wall structure, so as to respectively correspond to the first main magnetic plate 11111 and the first main magnet 11121 of the first magnetic return component 111 arranged above, and the second main magnetic plate 12111 and the second main magnet 12121 of the second magnetic return component 121 arranged below, so that each of the first connecting parts 103, the first main magnetic plate 11111 and the first main magnet 11121 form a complete magnetic field above the magnetic conductive component 10, and each of the second connecting parts 104, the second main magnetic plate 12111 and the second main magnet 12121 form a complete magnetic field below the magnetic conductive component 10, so that the first magnetic return component 111 of the first speaker 11 and the second magnetic return component 121 of the second speaker 12 can form two completely independent magnetic fields above and below (as shown). Figure 5B shown).

[0069] In the embodiments of the present invention (such as Figure 2 and Figure 3 As shown in FIG. 1 , the first speaker seat 112 has a first docking portion 1121 at both ends, and the second speaker seat 122 has a second docking portion 1221 at both ends. Each of the first docking portions 1121 is combined with each of the first assembly portions 103, and each of the second docking portions 1221 is combined with each of the second assembly portions 104. Each of the first assembly portions 103 and the first docking portion 1121 of the first speaker seat 112 can be a concave-convex structure, a snap-fit ​​structure, or an inlay structure that docks with each other, and each of the second assembly portions 104 and the second docking portion 1221 of the second speaker seat 122 can be a concave-convex structure, a snap-fit ​​structure, or an inlay structure that docks with each other. In this way, the first speaker seat 112 of the first speaker 11 and the second speaker seat 122 of the second speaker 12 can be firmly combined with the magnetic conductive component 10 to maintain the stability of the first speaker 11 and the second speaker 12 when they move on the two side surfaces of the magnetic conductive component 10.

[0070] In the embodiments of the present invention (such as Figure 2 and Figure 3 As shown in the figure, the two ends of the first speaker seat 112 respectively have a first combining portion 1122, and the two ends of the second speaker seat 122 respectively have a second combining portion 1222, and each of the second combining portions 1222 is correspondingly assembled with each of the first combining portions 1122, and each of the second combining portions 1222 and each of the first combining portions 1122 can be a concave-convex structure, a snap-fit ​​structure, or an embedded structure that docks with each other, so that the second speaker seat 122 and the first speaker seat 112 are firmly combined with each other to maintain the stability of the first speaker 11 and the second speaker 12 when they move on the two side surfaces of the magnetic conductive component 10.
