To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.

Referring to FIGS. 1 and 2, as shown in the drawings, the present disclosure provides a double-sided vibrating speaker 1 comprising: a magnet member 11, a first vibration member 12 and a second vibration member 13. The structure of the first vibration member 12 may be the same as the structure of the second vibration assembly 13, and the first vibration member 12 and the second vibration member 13 may be symmetrical with the magnet member 11 as the center.

Referring to FIGS. 3 to 7, as shown in the drawings, the magnet member 11 comprises a main magnetic unit 111, a first magnetic unit 112 and a second magnetic unit 113, the main magnetic unit 111 has a main magnetic plate 1111 and two side magnetic plates 1112, the main magnetic plate 1111 has at least one air vent 1115, each the side magnetic plate 1112 is provided on two sides of the main magnetic plate 1111, the main magnetic plate 1111 respectively has at least one assembly part 1113 at two sides, each the side magnetic plate 1112 has at least one docking part 1114 in combination with the assembly part 1113, the profile of the main magnetic unit 111 forms an H-shape, the first magnetic unit 112 is disposed on one surface of the main magnetic plate 1111, the second magnetic unit 113 is disposed on another surface of the main magnetic plate 1111, the first magnetic unit 111 has a first magnetic gap 114, the second magnetic unit 113 has a second magnetic gap 115.

The first vibration member 12 comprises a first speaker frame 121, a first voice coil 122 and a first diaphragm 123, the first speaker frame 121 is configured with a surface of the magnet member 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 frame 121.

The second vibration member 13 comprises a second speaker frame 131, a second voice coil 132 and a second diaphragm 133, the second speaker frame 131 is configured with another surface of the magnet member 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 frame 131, the second speaker frame 131 and the first speaker frame 121 are combined with each other.

When the double-sided vibrating speaker 1 of the present disclosure is used, it may be combined with a cabinet (not shown in figures), so that the first vibration member 12 and the second vibration member 13 are provided on two sides of the magnet member 11 in an up-down symmetrical manner, and share the magnet member 11, whereby the first vibration member 12 and the second vibration member 13 respectively go with the first magnetic unit 112 and the second magnetic unit 113 to form two completely independent magnetic fields located in the upper and lower positions (as shown in FIGS. 1, 2 and 8 to 10), and thus the first voice coil 122 and the second voice coil 132 bring the vibration of the first diaphragm 123 and the second diaphragm 133 through the electromagnetic action.

When the first vibration member 12 and the second vibration member 13 actuate, the first voice coil 122 and the second voice coil 132 receive an electronic signal inputted from outside, so that the first diaphragm 123 and the second diaphragm 133 simultaneously actuate outward and simultaneously actuate inward, when the first diaphragm 123 and the second diaphragm 133 simultaneously actuate outward, the air is pushed to vibrate and sound, and when the first diaphragm 123 and the second diaphragm 133 simultaneously actuate inward, the two forces will offset each other through the air vent 1115, so that the first vibration member 12 and the second vibration member 13 implement the function of vibration reduction, in order to avoid the force generated by the first diaphragm 123 and the second diaphragm 133 actuating to drive the entire double-sided vibrating speaker 1 followed by vibration.

Accordingly, in the case of constant size, the double-sided vibrating speaker 1 of the present disclosure may implement a two-way sounding effect, thereby enhancing the output volume and bass of the double-sided vibrating speaker 1 by the design of double-sided diaphragm including the first diaphragm 123 and the second diaphragm 133. More importantly, the first vibration member 12 and the second vibration member 13 may be actuated at the same time, so the force between each other is offset, and the vibration control of the double-sided vibrating speaker 1 is further increased, in order to prevent the first diaphragm 123 and the second diaphragm 133 at vibrating from driving the entire double-sided vibrating speaker 1 to produce unnecessary vibration, so as to avoid resonance to produce noise and distortion. In addition, the double-sided vibrating speaker 1 of the present disclosure may allow the first vibration member 12 and the second vibration member 13 respectively to go with the first magnetic unit 112 and the second magnetic unit 113 to form two completely independent magnetic paths located in the upper and lower positions by the H-shaped design of the main magnetic unit 111, and a main magnetic plate 1111 is shared to form two completely independent magnetic paths located in the upper and lower positions, so the overall height of the double-sided vibrating speaker 1 will not be increased. Further, the main magnetic plate 1111 is combined with each the side magnetic plate 1112 by each the assembly part 1113 and each the docking part 1114, so that each the assembly part 1113 and each the docking parts 1114 can be connected by laser welding, in addition to reducing the difficulty of forming the main magnetic unit 111 in metal stamping, it may also reduce the thickness of the double-sided vibrating speaker 1 of the present disclosure.

Further, in the assembly of the double-sided vibrating speaker 1, it only needs to first assemble the magnet member 11, the first vibration member 12 and the second vibration member 13 respectively, and then three components including the magnet member 11, the first vibration member 12 and the second vibration member 13 are directly combined and fixed, the assembly of the double-sided vibrating speaker 1 can be completed. It means that the double-sided vibrating speaker 1 is disassembled into three modules of semi-finished products, and then they are assembled into a finished product at one time, and thus the quality of assembly is more stable and more efficient.

In addition to the above embodiments, in an embodiment of the present disclosure (as shown in FIGS. 1 to 7), the main magnetic plate 1111 respectively has the air vents 1115 on two sides, each the air vent 1115 is recessed, the first speaker frame 121 and the second speaker frame 131 respectively have at least one open pore 10 on two sides, each the open pore 10 communicates each the air vent 1115.

The main magnetic unit 111 is a metal magnetic permeability material (e.g., low carbon steel), so it is difficult to directly form an H shape through the conventional metal stamping process. In order to achieve the main magnetic unit 111 with an H-shaped profile, the main magnetic plate 1111 is planar and the main magnetic plate 1111 has four convex parts after the two recessed air vents 1115 are provided, and each the side magnetic plate 1112 may be provided with two through holes to correspond to the convex parts, in order to combine with the main magnetic plate 1111.

Accordingly, when the main magnetic plate 1111 and each the side magnetic plate 1112 are carried out the laser welding, there is a space to place a solder ball (not shown in the figures), therefore, even if the solder ball protrudes out of the wall surface of each the side magnetic plate 1112, because there is a space area 20 between each the side magnetic plate 1112 and the first speaker frame 121 and the second speaker frame 131, when the magnet member 11 is assembled to the first speaker frame 121 and the second speaker frame 131, the interference will not be produced.
