Detailed Description
For a full understanding of the objects, features and effects of the present invention, reference should be made to the following detailed description of the invention, taken in conjunction with the accompanying drawings, in which:
referring to fig. 1 to 11, as shown in the drawings, the present invention provides a thin type double-sided vibration speaker 1, which comprises: a main magnetic base 11, a main magnetic circuit unit 12, two side magnetic circuit units 13, a first speaker base 14, a first diaphragm 15, a first voice coil 16, a second speaker base 17, a second diaphragm 18, and a second voice coil 19.
The main magnetic base 11 includes a central magnetic conductive plate 111 and two magnetic conductive end plates 112, the magnetic conductive end plates 112 are integrally connected to two ends of the central magnetic conductive plate 111, and an installation portion 113 is formed between the magnetic conductive end plates 112 and the central magnetic conductive plate 111 by a height difference, and the installation portion 113 presents a concave state.
The main magnetic circuit unit 12 is disposed on a surface of the central magnetic conductive plate 111 and is located at the mounting portion 113, the main magnetic circuit unit 12 includes a main magnet 121 and a main magnetic conductive plate 122, the main magnet 121 is disposed on the surface of the central magnetic conductive plate 111, and the main magnetic conductive plate 122 is disposed on the main magnet 121.
The side magnetic circuit units 13 respectively correspond to two sides of the main magnetic circuit unit 12, the side magnetic circuit units 13 respectively include at least one side magnet 131, a first side magnetic conductive plate 132 and a second side magnetic conductive plate 133, the first side magnetic conductive plate 132 is disposed on one surface of the side magnets 131, the second side magnetic conductive plate 133 is disposed on the other surface of the side magnets 131, the first side magnetic conductive plate 132 and the magnetic conductive end plate 112 correspond to the main magnetic conductive plate 112, two ends of the second side magnetic conductive plate 133 are respectively integrally connected with a second magnetic conductive connecting plate 134, the second side magnetic conductive plate 133 and the second magnetic conductive connecting plate 134 are connected into a ring shape and correspond to the central magnetic conductive plate 111, and a hollow area 115 is respectively formed between the first side magnetic conductive plate 132 and the central magnetic conductive plate 111. Since the mounting portion 113 is in a recessed state, after the main magnetic circuit unit 12 and the side magnetic circuit unit 13 are disposed, the heights of the main magnetic circuit unit 12 and the side magnetic circuit unit 13 can be greatly reduced, and the overall height of the thin double-sided vibration speaker 1 can be reduced, thereby achieving the requirement of thinning. In addition, the air-permeable area 115 between the first side magnetic-permeable plate 132 and the central magnetic-permeable plate 111 can make the air flow of the first diaphragm 15 and the second diaphragm 18 have more direct canceling space, thereby achieving better vibration reduction effect.
The first speaker seat 14 is coupled to a surface of the first side magnetic conductive plate 132 and a surface of the magnetic conductive end plate 112 of the main magnetic seat 11.
The first diaphragm 15 is disposed on the first speaker seat 14.
The first voice coil 16 is disposed on the first diaphragm 15, and the first voice coil 16 is movably disposed on the inner edge of the mounting portion 113 and between the main magnetic circuit unit 12 and the side magnetic circuit unit 13.
The second speaker seat 17 is combined with the other surface of the magnetic conductive end plate 112 of the main magnetic seat 11 and combined with the first speaker seat 14.
The second diaphragm 18 is disposed on the second speaker seat 17.
The second voice coil 19 is disposed on the second diaphragm 18, and the second voice coil 19 is movably disposed on the outer edge of the mounting portion 113 and between the main magnetic circuit unit 12 and the side magnetic circuit unit 13, so that the size of the first voice coil 16 is smaller than that of the second voice coil 19 in the present invention.
When the thin double-sided vibration speaker 1 of the present invention is in operation, the thin double-sided vibration speaker 1 can be combined with a sound box (not shown), so that the first voice coil 16 forms an independent magnetic field above the side magnetic circuit units 13 through the main magnetic circuit unit 12, and the second voice coil 19 forms an independent magnetic field below the side magnetic circuit units 13 through the main magnetic circuit unit 12, so that the thin double-sided vibration speaker 1 forms a continuous magnetic field up and down, and the first voice coil 16 and the second voice coil 19 push the first diaphragm 15 and the second diaphragm 18 to vibrate through electromagnetic action.
When the thin double-sided vibration speaker 1 is operated, the first voice coil 16 and the second voice coil 19 receive an externally input electronic signal, so that the first diaphragm 15 and the second diaphragm 18 are operated outwards and inwards simultaneously, when the first diaphragm 15 and the second diaphragm 18 are operated outwards simultaneously, air is pushed to vibrate and sound, and when the first diaphragm 15 and the second diaphragm 18 are operated inwards simultaneously, the two acting forces are mutually propped against each other to realize the vibration reduction function, so that the acting force generated by the operation of the first diaphragm 15 and the second diaphragm 18 is avoided, and the whole thin double-sided vibration speaker 1 is driven to vibrate.
In addition, although the magnetic force of the main magnetic circuit unit 12 is larger than that of the side magnetic circuit unit 13, the first voice coil 16 collocated with the main magnetic circuit unit 12 has smaller size, and the second voice coil 19 collocated with the side magnetic circuit unit 13 has larger size, so that the acting forces on the first vibrating diaphragm 15 and the second vibrating diaphragm 18 are the same, and the first vibrating diaphragm 15 and the second vibrating diaphragm 18 have the same size and the same mass, so that the purpose of shock absorption can be achieved.
Therefore, the thin double-sided vibration loudspeaker 1 of the invention can achieve the requirements of thinning and double-sided sound production effect, and the double-sided sound production effect is achieved through the design of the double-sided diaphragms of the first diaphragm 15 and the second diaphragm 18, thereby improving the output volume and the bass effect of the thin double-sided vibration loudspeaker 1. In addition, the thin double-sided vibration speaker 1 of the present invention can cancel the acting force of the first and second diaphragms 15 and 18 and further increase the vibration damping force of the thin double-sided vibration speaker 1, so as to prevent the first and second diaphragms 15 and 18 from vibrating and driving the whole thin double-sided vibration speaker 1 to generate unnecessary vibration, thereby avoiding noise and distortion caused by resonance.
In addition, in the thin double-sided vibration speaker 1 of the present invention, the first voice coil 16 and each of the side magnetic circuit units 13 form an upper independent magnetic field through the main magnetic circuit unit 12, and the second voice coil 19 and each of the side magnetic circuit units 13 form a lower independent magnetic field through the main magnetic circuit unit 12, and the upper and lower continuous magnetic fields share one main magnetic base 11, so that the overall height of the thin double-sided vibration speaker 1 is not increased.
