The present invention generally relates to a vibration-based speaker box device; in particular, it relates to a speaker box device capable of propagating audio signals by way of vibrations.
It is well-known that the sound generated by the currently available speaker boxes is reproduced by the conventional speaker which essentially comprises a magnetic circuit system, a vibration system as well as a suspension system for supporting vibrations, wherein the magnetic circuit system includes a washer, a magnet and a U-shaped iron; the vibration system includes a sound coil, a supporting frame and a diaphragm; and the suspension system mainly consists of a corrugated rim located around the peripheral edge of the diaphragm in the speaker and a damper for fixing the sound coil.
Herein the sound coil oscillates in the magnetic gap created by the magnetic circuit system, and the operational principle of the above-mentioned speaker can be largely explained as below: transferring alternating current implicitly comprising audio signals to the sound coil in order to cause the sound coil to vibrate vertically in the magnetic gap, and making the vibrations of the sound coil bring the diaphragm to move by means of the framework such that the diaphragm vibrates up-down and compresses the air in order to reproduce the sound.
However, the transfer range of the sound generated by the vibrations in each speaker is limited; as such, it would be an optimal solution suppose it is possible to develop a sort of speaker box device which can fix the surface of a vibrator onto a vibration board in contact, and when the vibrator operates, the generated vibrations can spread out on the vibration board because of the fixed contact between the vibrator and the vibration board thereby effectively increasing its acoustic transfer range.
A vibration-based speaker box device according to the present invention comprises: a vibration body, including: a first case, formed with an accommodation area; a vibrator, placed within the accommodation area and having at least a contact board, a supporting frame, a sound coil wound around the lateral surface of the supporting frame, a damper and a magnetic package, in which the lower part of the contact board is connected to the supporting frame, the supporting frame can be placed within the magnetic package, and one end of the damper is connected to the lateral surface of the supporting frame while the other end thereof is connected to the lateral edge of the magnetic package; a filler, placed between the accommodation area and the vibrator so that, through which, the vibrator can be combined within the accommodation area; in which the contact board of the vibrator can be fixedly bonded onto a vibration board and, after bringing the damper to vibrate by means of the sound coil of the vibrator, it is possible to make the magnetic package vibrate conjunctively, and the vibration can be further transferred to the entire vibration body via the filler such that the vibration board in contact with the vibrator can spread the kinetic energy generated by the vibrations of the vibration body onto the whole vibration board; a control body, including: a second case, connected to the first case; an electric circuit board, set up within the second case and electrically connected to the vibrator of the vibration body; and a battery, installed within the second case and electrically connected to the electric circuit board; in which the control body can send an audio signal to the vibration body so as to, by means of the vibrations of the vibration body, spread the audio signal through the vibration board.
More specifically, the contact board of the vibrator is a metal plate or a plastic board.
More specifically, the filler is a rubber, a sponge, an ethylene vinyl acetate copolymer, or a mixture containing at least two of the above-mentioned materials.
More specifically, the vibration board is a wooden board, a glass plate, a metal plate or a plastic board.
More specifically, the surface of the vibration board can be a flat surface or a non-flat surface.
More specifically, the surface on the other side of the first case in the vibration body is combined with a binding component thereby allowing the vibration body to be attached in binding onto the surface of the vibration board.
More specifically, a combination part protrudes outwards from one lateral surface of the first case in the vibration body, while an accommodation part is formed on the other lateral surface of the first case in the vibration body in correspondence with the combination part, and a connection part is further concavely configured on the control body in correspondence with the combination part of the vibration body, in which the connection part internally includes a second connection end, and the first connection end and the second connection end can engage to form an electric connection.
More specifically, the vibrator of the vibration body is electrically connected to a first connection end, the electric circuit board of the control body is electrically connected to the second connection end, and the control body can transfer the audio signal to the second connection end via the connection of the second connection end and the first connection end.
More specifically, the first case and the second case can be fixedly connected or detachably connected.
More specifically, one side on the second case of the control body is further configured with a touch area which can be pressed thereby generating and transferring a signal to the electric circuit board.
More specifically, the inside of the electric circuit board further includes a wireless connection module and/or a wired connection plug which can be used to transfer information, i.e., the audio signals and/or control signals, to the control body by way of a wireless connection and/or a wired connection.

Herein the vibration body 1 includes at least a first case 11, a vibrator 12 and a filler 13, and a combination part 111 protrudes from one lateral surface of the first case 11, while an accommodation part 112 is formed on the other lateral surface of the first case 11 in correspondence with the combination part 111.
In addition, the vibrator 12 is placed within the accommodation area 112 and electrically connected to the first connection end 1111, and has at least a contact board 121, a supporting frame 122, a sound coil 123 wound around the lateral surface of the supporting frame122, a damper 124 and a magnetic package (consisting of a washer 125, a magnet 126 and a U-shaped iron 127), in which the contact board 121 is a metal plate or a plastic board, and the lower part of the contact board 121 is connected to the supporting frame 122, the supporting frame 122 can be placed within the U-shaped iron 127 of the magnetic package, and one end of the damper 124 is connected to the lateral surface of the supporting frame 122, while the other end of the damper 124 is connected to the lateral edge of U-shaped iron 127 in the magnetic package.
Moreover, the filler 13 is placed between the accommodation area 112 and the vibrator 12 so that, through the filler 13, the vibrator 12 can be combined within the accommodation area 112; also, the filler 13 is a rubber, a sponge, an ethylene vinyl acetate copolymer, or a mixture containing at least selected two of the above-mentioned materials.
Herein the control body 2 includes a second case 21, an electric circuit board 22, a battery 23 and a touch electric circuit board 241; also, a connection part 211 is further concavely configured in the second case 21 in correspondence with the combination part 111 of the vibration body 1, the connection part 211 internally includes a second connection end 2111, and the first connection end 1111 and the second connection end 2111 can engage in contact to form an electric connection.
It should be understood that the touch electric circuit board 241 corresponds to the touch area 24 on one lateral surface of the second case 21, so it is possible to tab the touch area 24 in order to press on the touch electric circuit board 241, and the signals generated by pressing the touch electric circuit board 241 can be further transferred to the electric circuit board 22.

Analogously, the inside of the electric circuit board 22 may optionally further include a wired connection plug (not shown) used to transfer the information, i.e., the audio signal and/or control signal, to the control body 2 in a wired connection fashion.
Furthermore, the first case and the second case can be designed to enable fixed or detachable connection, and, particularly by means of the detachable connection configuration, the control body 2 can be separated in order to perform electric recharging; in use, the combination part 111 and the connection part 211 can be combined for operation.
