Description

Technical Field

[0001] The utility model belongs to the technical field of sound transmission devices, and in particular relates to a vibration type floor speaker device. Background Art

[0002] In tall, large spaces like railway waiting halls and convention centers, broadcasts often have difficulty being clearly heard. The root cause is that speakers aren't positioned close enough to the audience. In these tall, large spaces, speakers are often hung from the ceiling, side walls, or raised internal service structures. This creates a long distance between the speakers and the audience, leading to significant interference. Suspending speakers from high altitudes presents both aesthetic and safety issues. Furthermore, due to limited lateral height, speakers mounted on side walls and service structures often lack sufficient coverage. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0029] See attached Figure 1 and attached Figure 2 The utility model designs a vibration type floor speaker device, which includes a speaker shell 1 and a vibration speaker 2 and a controller 3 arranged inside the speaker shell.

[0030] The speaker housing 1 comprises a mounting box 11 and a hard vibration plate 12 (that is, the mounting box has a bottom panel and a circle of side panels, and an open top) mounted on the top of the mounting box. The hard vibration plate 12 is mounted on the top open portion of the mounting box 11 by bolts. The vibration end of the vibration speaker 2 is connected to the bottom surface of the hard vibration plate 12. The controller 3 is connected to the vibration speaker 2 for converting a voice signal into a vibration drive signal for driving the vibration speaker to vibrate, so that the vibration end of the vibration speaker drives the hard vibration plate to vibrate. Further, a power module 4 is also provided in the mounting box 11 for powering the vibration speaker 2 and the controller 3.

[0031] An upper gasket, a lower gasket, and an outer gasket made of elastic material are provided at the installation portion between the outer edge of the hard vibration plate and the installation box; wherein the upper gasket is provided at the interlayer installation portion between the upper side of the outer edge of the hard vibration plate and the installation box, and is used to provide elastic (flexible) support for the upper side of the hard vibration plate; the lower gasket is provided at the interlayer installation portion between the lower side of the outer edge of the hard vibration plate and the installation box, and is used to provide elastic (flexible) support for the lower side of the hard vibration plate; the outer gasket is provided at the interlayer installation portion between the outer side of the outer edge of the hard vibration plate and the installation box, and is used to provide elastic (flexible) support for the outer side of the hard vibration plate. Through the combined action of the upper gasket, the lower gasket, and the outer gasket, the hard vibration plate 12 can vibrate under the drive of the vibration speaker 2.

[0032] The mounting box must have a solid retaining wall structure outside the outer edge of the rigid vibration plate. This prevents materials in the installation environment (such as floor tiles, concrete, and caulking compound) from contacting the rigid vibration plate and affecting its vibration. The outer gasket is positioned between this retaining wall structure and the outer edge of the rigid vibration plate.

[0033] See below for details. Figure 3 and attached Figure 4 , specifically introduce the design structure of the upper gasket, lower gasket and outer gasket:

[0034] A groove 1101 is provided at the inner top of the side panel 111 of the installation box 11 , and the outer side of the groove has a solid portion 1102 of the side panel 111 to form a solid retaining wall structure to prevent substances in the installation environment from contacting the hard vibration plate.

[0035] A pressing plate 112 is further provided on the top of the side panel 111 of the installation box 11 . The pressing plate 112 is mounted on the top of the side panel 111 by means of bolts 7 .

[0036] The outer edge of the hard vibration plate 12 is an L-shaped structure, that is, a protrusion 121 protruding outward is provided at the bottom of the outer edge of the hard vibration plate 12. The protrusion 121 is installed in the space between the bottom surface of the pressure plate 112 and the groove 1101, and an upper gasket 01 is provided between the bottom surface of the pressure plate 112 and the top surface of the protrusion 121, a lower gasket 02 is provided between the bottom surface of the groove and the bottom surface of the protrusion 121, a first outer gasket 03 is provided between the inner side surface of the groove and the outer side surface of the protrusion 121, and a second outer gasket 04 is provided between the inner side surface of the pressure plate 112 and the outer edge surface of the hard vibration plate 12 on the upper side of the protrusion 121.

[0037] The pressure plate 112 is mounted on the top of the side panel 111 by means of bolts 7. Figure 4 , a corresponding bolt mounting hole 71 is provided on the pressure plate 112, and the bolt mounting hole 71 is preferably a horizontal hole to ensure that after the bolt 7 is installed, the top surface of the bolt 7 is flush with the top surface of the pressure plate 112; a corresponding threaded hole 72 is provided on the top of the side panel 111 of the mounting box 11 for threaded connection with the bolt 7; a corresponding through hole 73 is provided on the protrusion 121 of the hard vibration plate 12 for allowing the bolt 7 to pass through, and the aperture of the through hole 73 is larger than the diameter of the bolt 7 to ensure that the hard vibration plate 12 has a vibration activity margin.

[0038] For further information, see the attached Figure 5 If the size of the entire speaker housing 1 is large, in order to ensure sufficient strength of the hard vibration plate 12, a support frame 8 can also be set inside the speaker housing 1. The bottom of the support frame is fixed to the bottom surface of the installation box 11 by bolts 82, and a rubber pad 81 is set on the top of the support frame to prevent people or heavy objects from bending the hard vibration plate 12.

[0039] Furthermore, the shape of the speaker housing 1 is not limited, except Figure 1 The rectangular shape shown can also be cylindrical (see attached Figure 6 ), square or other shapes.

[0040] When used, the vibration floor speaker device of the present invention is embedded in the ground of a large public space with a high altitude, such as a railway waiting hall or a convention and exhibition center, and multiple vibration floor speaker devices are arranged in an array. Thus, a public broadcasting system is constructed by using this array-arranged vibration floor speaker device. The vibration floor speaker device of the present invention is very close to the audience, so that broadcasting can be performed at a very low volume, reducing mutual interference between long-distance speakers, achieving a wide coverage range, and greatly improving the audience's clarity.

[0041] The vibration floor speaker device of the utility model can be combined with the floor tile grid of the public space, and the vibration floor speaker device in the form of a rectangle, a cylinder, etc. can be used to replace part of the floor tiles (see the attached Figure 7 and attached Figure 8 , wherein the number 00 represents a floor tile, and 01 represents a vibration floor speaker device), a square-shaped vibration floor speaker device can also replace the entire floor tile (see attached Figure 9 , where the number 00 represents floor tiles and 01 represents a vibration-type floor speaker device), thereby achieving an organic combination of floor speakers and decorative effects, and realizing the construction of a public broadcasting system through an array arrangement at a certain distance.

[0042] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
