In an embodiment of the invention, the first magnetic component 111 includes a first magnetic conducting set 1111 and a first magnet set 1112, the first magnetic conducting set 1111 is stacked on the first magnet set 1112, the first magnet set 1112 is disposed on a side surface of the magnetic conducting component 10, wherein the first magnetic conducting set 1111 has a first main magnetic conducting plate 11111 and two first sub magnetic conducting plates 11112, the first sub magnetic conducting plates 11112 are respectively disposed on two sides of the first main magnetic conducting plate 11111, the first magnet set 1112 has a first main magnet 11121 and two first sub magnets 11122, and the first sub magnets 11122 are respectively disposed on two sides of the first main magnet 11121.
In an embodiment of the invention, the second magnetic component 121 includes a second magnetic conducting set 1211 and a second magnet set 1212, the second magnetic conducting set 1211 is stacked on the second magnet set 1212, the second magnet set 1212 is disposed on the other side surface of the magnetic conducting component 10, wherein the second magnetic conducting set 1211 has a second main magnetic conducting plate 12111 and two second sub magnetic conducting plates 12112, the second sub magnetic conducting plates 12112 are respectively located on two sides of the second main magnetic conducting plate 12111, the second magnet set 1212 has a second main magnet 12121 and two second sub magnets 12122, and the second sub magnets 12122 are respectively located on two sides of the second main magnet 12121.
When the dual-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 disposed on 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 (as shown in fig. 4, fig. 5A, and fig. 5B), so as to push the first diaphragm 114 and the second diaphragm 124 to vibrate through the first voice coil 113 and the second voice coil 123 by electromagnetic action.
The vibration modes of the first speaker 11 and the second speaker 12 during movement are shown in fig. 6, after the first voice coil 113 and the second voice coil 123 receive an external input electronic signal, the first diaphragm 114 and the second diaphragm 124 move outward (e.g., in the direction of the arrow of part (a) in fig. 6) and inward (e.g., in the direction of the arrow of part (b) in fig. 6) at the same time, when the first diaphragm 114 and the second diaphragm 124 move outward, the air is pushed to vibrate to generate sound, and when the first diaphragm 114 and the second diaphragm 124 move inward, the two acting forces are mutually cancelled, so that the first speaker 11 and the second speaker 12 realize the function of damping, and the acting force generated by the movement of the first diaphragm 114 and the second diaphragm 124 is prevented from driving the whole dual-sided speaker 1 to vibrate.
Thus, the dual-sided speaker 1 of the present invention can realize a two-way sound effect by the design of the dual-sided diaphragms of the first diaphragm 114 and the second diaphragm 124 under the condition of unchanged size, so as to increase the output volume and bass of the dual-sided speaker 1. More importantly, the simultaneous movement of the first speaker 11 and the second speaker 12 can counteract the acting force therebetween, and further increase the vibration suppression capability of the dual-sided speaker 1, so as to prevent the first diaphragm 114 and the second diaphragm 124 from vibrating and driving the entire dual-sided speaker 1 to generate unnecessary vibration, thereby avoiding noise and distortion due to resonance.
In an embodiment of the present invention (as shown in fig. 2 and 3), the magnetic conductive assembly 10 has a plurality of opening portions 101 communicating two side surfaces, and the first magnetic gap 115 and the second magnetic gap 125 correspond to the opening portions 101. Thus, the acting force generated by the first diaphragm 114 and the second diaphragm 124 during movement can be more fully contacted and offset through the opening portion 101, so as to increase the capability of suppressing vibration of the dual-sided speaker 1, and prevent the entire dual-sided speaker 1 from generating unnecessary vibration when the first diaphragm 114 and the second diaphragm 124 vibrate, so as to avoid noise and distortion caused by resonance.
In the embodiment of the present invention (as shown in fig. 2 and 3), the magnetic conductive assembly 10 has notches 102 on both sides. Thus, through the matching of the notch portion 102 or the matching of the opening portion 101 and the notch portion 102, the acting force and the airflow generated when the first diaphragm 114 and the second diaphragm 124 move can be sufficiently offset, so as to increase the capability of suppressing the vibration of the dual-sided speaker 1, and prevent the entire dual-sided speaker 1 from generating unnecessary vibration when the first diaphragm 114 and the second diaphragm 124 vibrate, so as to avoid the noise and distortion generated by resonance.

In an embodiment of the present invention (as shown in fig. 2 and 3), two ends of the first horn base 112 respectively have a first abutting portion 1121, two ends of the second horn base 122 respectively have a second abutting portion 1221, each first abutting portion 1121 is combined with each first abutting portion 103, each second abutting portion 1221 is combined with each second abutting portion 104, each first abutting portion 103 and the first abutting portion 1121 of the first horn base 112 may be a concave-convex structure, a snap structure, or an engagement structure, and each second abutting portion 104 and the second abutting portion 1 of the second horn base 122 may be a concave-convex structure, a snap structure, or an engagement structure, which are abutted with each other. Thus, the first speaker base 112 of the first speaker 11 and the second speaker base 122 of the second speaker 12 can be firmly combined with the magnetic conductive component 10, so as to maintain the stability of the first speaker 11 and the second speaker 12 when moving on the two side surfaces of the magnetic conductive component 10.
