In order to facilitate the replacement of the flat panel sound as a wall painting and to make the interior of the vehicle have different environments, the present embodiment makes the flat panel sound have different wall paintings by changing the vibration plate 120, that is, the vibration plate 120 can be quickly separated from the rear case 130 and quickly attached to the rear case 130.
In particular, referring to fig. 5-7, the mounting and dismounting device 140 of the present embodiment includes a fixing component 141 and a positioning column 146; the positioning column 146 is fixedly arranged on the back surface of the frame 110, one side surface of the positioning column 146 is provided with a plurality of triangular teeth 147, and the triangular teeth 147 are fixedly connected with the side surface of the positioning column 146; the inside of the fixing assembly 141 is provided with a first rectangular cavity 142 communicated with the outside, and a sliding rail 149 is arranged between the side wall of the inside of the first rectangular cavity 142 and the other side surface of the positioning column 146 opposite to the triangular tooth 147; an opening 143 is disposed on the fixing component 141 at one side of the first rectangular cavity 142, a threaded hole (not shown in the figure) is disposed on the frame 110, the opening 143 and the threaded hole are coaxially configured, an adjusting rod 145 is disposed in the opening 143 and the threaded hole, one end of the adjusting rod 145 is spherical, extends into the fixing component 141, and the other end is fixedly connected with an adjusting block 144.
With the above arrangement, the positioning posts 146 with the triangular teeth 147 may extend into the first rectangular cavity 142, so as to mount and dismount the frame 110 and the vibration plate 120 relative to the rear case 130.
In this embodiment, the positioning assembly 141 includes a second rectangular cavity 148; the second rectangular cavity 148 is disposed on the left side of the first rectangular cavity 142, and the right side is communicated with the first rectangular cavity 142; a plurality of guide plates 150 are arranged in the second rectangular cavity 148, the front section and the rear section of the guide plates 150 are fixedly connected with the inner wall of the second rectangular cavity 148, and a stepped hole is formed in one side, close to the first rectangular cavity 142, of the guide plates 150, so that the limiting function is realized; a corresponding number of first springs 151 are arranged between the guide plates 150 or between the guide plates and the side walls of the second rectangular cavity 148, wedge blocks 152 are arranged on the left sides of the first springs 151, the left ends of the first springs 151 are fixedly connected with straight line segments of the wedge blocks 152, and the right ends of the first springs 151 are fixedly connected with the bottoms of the triangular teeth 147; the wedge 152 has a slope, and the spherical end of the adjusting rod 145 is in contact connection with the slope of the wedge 152.
It will be appreciated that, to facilitate installation of the bezel 110, the triangular teeth 147 on the left side of the positioning posts 146 have a greater slope of the upper bevel, a lesser slope of the lower bevel, and the triangular teeth 147 at the second rectangular cavity 148 have a lesser slope of the upper bevel and a greater slope of the lower bevel.
Therefore, when the frame 110 is installed, the four positioning columns 146 extend into the first rectangular cavity 142, and as the triangular teeth 147 positioned at the positioning columns 146 and the second rectangular cavity 148 are meshed with inclined planes with smaller gradients in the installation direction, the installation effort is smaller, and the installation method has the characteristics of simplicity and convenience; when the installation is finished, the triangle 147 engaged in the disassembly direction has a larger gradient, so that the frame 110 is not easy to fall off after the installation is finished; when the frame 110 is disassembled, the adjusting block 144 is rotated, so that the adjusting rod 145 moves upwards under the action of the threaded hole, the wedge block 152 moves leftwards under the action of the spring force, the length of the first spring 151 is extended, the spring force is reduced, and the positioning column 146 can be pulled out of the first rectangular cavity 142 of the fixing component 141 under the driving of the frame 110; the efficiency of assembling and disassembling the vibration plate 120 and the frame 110 is improved.
It can be understood that, during the installation process of the frame 110 and the vibration plate 120, the inner side of the vibration plate 120 contacts the driver 160, and the pressure of the driver 160 to the vibration plate 120 directly affects the sound quality of the flat panel sound, and when the pressure is too high, the sound quality of the flat panel sound is reduced; when the pressure is too small, the sound emitting effect is affected by insufficient contact of the inside of the vibration plate 120 with the driver 160.
In order to solve the problem that the pressure of the driver 160 to the vibration plate 120 is too large or too small in the installation process, and prevent the sound quality of the flat panel sound from being reduced due to the too large or too small pressure, referring to fig. 8, in the present embodiment, a plurality of vibration plate overload prevention devices 180 are disposed on four end surfaces where the vibration plate 120 and the frame 110 are in contact, and the vibration plate overload prevention devices 180 include semicircular protrusions 181, second springs 182, cylindrical cavities 183, and semicircular grooves 184; the four end surfaces of the vibration plate 120 are provided with a plurality of semicircular grooves 184, a cylindrical cavity 183 is arranged at the inner side of the frame 110 and corresponds to the semicircular grooves 184, one end of the cylindrical cavity 183 is closed, an opening at one end corresponds to the semicircular grooves 184, and a stepped hole is formed at the opening, so that the limiting function is realized; the semicircle protruding 181 sets up in cylindricality cavity 183 opening part, semicircle protruding 181 sphere and semicircle recess 184 looks adaptation, second spring 182 sets up inside cylindricality cavity 183, one end and cylindricality cavity 183 bottom fixed connection, the bottom fixed connection of semicircle protruding 181 of the other end.
It should be noted that, the vibration plate 120 is inlaid inside the frame 110 through the plurality of vibration plate overload protection devices 180, the second springs 182 need to be springs with suitable elastic coefficients, when the frame 110 and the vibration plate 120 are installed, along with the positioning columns 146 being inserted into the first rectangular cavity 142, if the driver 160 applies excessive pressure to the vibration plate 120, at this time, the vibration plate 120 will deviate from the frame 110 under the action of the pressure, so as to avoid the influence on sound quality caused by the excessive pressure of the driver 160 on the vibration plate 120 due to installation; when this happens, the length of the positioning post 146 inserted into the first rectangular cavity 142 should be adjusted and reduced in time.
However, since the flat panel sound is sounded by transmitting the driver to the bending wave of the vibration plate, the appearance is light and thin, the driver power is smaller, the vibration amplitude generated by the vibration plate is smaller, and the effect of the bass region of the flat panel sound is poorer.
In order to solve the above-described problem, referring to fig. 4, the driver 160 of the present embodiment includes a constraint frame 161, a pallet 162, and a support cylinder 163; the constraint frame 161 is hollow, the upper end of the constraint frame is open, and the hollow part inside the constraint frame 161 is communicated with the outside through the opening; the support cylinder 163 is disposed at an opening at an upper end of the constraint frame 161, a supporting plate 162 is disposed at an upper end of the support cylinder 163, a lower end of the supporting plate 162 is fixedly connected with the support cylinder 163, and an upper end is in contact connection with the vibration plate 120.
