Description

Technical Field

[0001] The invention belongs to the technical field of sound transmission devices, and in particular relates to a loudspeaker installed on the ground. Background Art

[0002] In large spaces with high ceilings, such as railway waiting rooms and exhibition centers, broadcast sound often has difficulty being clearly transmitted, mainly because the speakers cannot be placed close to the audience. In these tall spaces, speakers are usually installed on the ceiling, the side of the wall, or on protruding structures in the room, resulting in a large distance between the speakers and the audience, and easy to cause sound interference between speakers. In addition, hanging speakers at high places may cause aesthetic and safety concerns. Moreover, due to the height limit of the side, speakers installed on walls and protruding structures in the room often cannot cover distant areas. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a ground mounted speaker that can effectively shorten the distance to the audience to ensure higher clarity. The speaker is mounted on the ground and is not limited by the installation position of the speaker.

[0004] The present invention is achieved through the following technical solutions:

[0005] A speaker installed on the ground, comprising a bottom box, a main shell, a vibration sounding board, a vibrator, a transmission frame, a main control circuit board, a power module and a vibration isolation sealing ring of the vibration sounding board;

[0006] The bottom box is used to be pre-installed at the ground location to be installed;

[0007] The main housing is used to be fixedly installed in the bottom box;

[0008] The vibration sound-generating plate is installed at the top port of the main housing;

[0009] The transmission skeleton is installed at the bottom of the vibration sounding plate and is located inside the main shell. The transmission skeleton includes a circular ring-shaped support edge, a middle mounting plate and an intermediate connecting piece, wherein the middle mounting plate is located at a position below the center of the circular ring-shaped support edge, and the middle mounting plate and the circular ring-shaped support edge are connected by an intermediate connecting piece; the circular ring-shaped support edge and the bottom surface of the vibration sounding plate are tightly fitted, and the bottom of the middle mounting plate is fixedly connected to the vibrator. When the vibrator vibrates, the vibration is transmitted to the circular ring-shaped support edge through the intermediate connecting piece, and then the circular ring-shaped support edge transmits the vibration to the vibration sounding plate;

[0010] The vibration sounding plate vibration isolation sealing ring is sleeved on the periphery of the transmission frame and the vibration sounding plate, and is used to provide elastic support on the top, bottom and sides of the transmission frame and the vibration sounding plate, so that the transmission frame and the vibration sounding plate can vibrate under the drive of the vibrator;

[0011] The main control circuit board is arranged in the main housing and is used to convert the voice signal into a vibration driving signal to drive the vibrator to drive the vibrator to work;

[0012] The power module is arranged in the main housing and is used to supply power to the main control circuit board.

[0013] In the above technical solution, the main shell is in the shape of a cone bowl, and its function is to provide a mounting base, the interior of which is used for integrated mounting of various functional components.

[0014] In the above technical solution, the intermediate connecting member may be a connecting arm structure, and the number of connecting arms is preferably 3, which are evenly spaced around the circumference; or, the intermediate connecting member may also be a conical surface structure.

[0015] In the above technical solution, the vibrator and the transmission frame are fixedly connected by vibrator fixing screws.

[0016] In the above technical solution, a circle of mounting grooves is provided on the inner side of the vibration isolation sealing ring of the vibration sounding plate, and the edges of the transmission frame and the vibration sounding plate are embedded in the mounting grooves, so that the top surface of the edge of the vibration sounding plate forms a top elastic support, the bottom surface of the circular support edge of the transmission frame forms a bottom elastic support, and the outer surface of the transmission frame and the vibration sounding plate forms a side elastic support.

[0017] In the above technical solution, a circle of stepped groove structure is provided at the top port of the main shell. After the vibration sounding plate vibration isolation seal ring, the transmission frame and the vibration sounding plate are combined, the vibration sounding plate vibration isolation seal ring is installed at the stepped groove structure, and a pressure ring is provided above the vibration sounding plate vibration isolation seal ring. Bolts are then used to vertically penetrate the pressure ring, the vibration sounding plate vibration isolation seal ring, the transmission frame and the vibration sounding plate to connect with the main shell.

[0018] The above technical solution also includes an upper cover and an upper cover vibration isolation sealing ring, which are installed on the top port of the main shell through the upper cover mounting bolts to cover the pressure ring to play a dust-proof and protective role.

[0019] The advantages and beneficial effects of the present invention are:

[0020] The floor speaker of the present invention can be embedded in the ground of a large public space with a high altitude, such as a railway waiting hall, a convention and exhibition center, to construct a public broadcasting system, which can effectively shorten the distance to the audience and ensure high clarity. It is installed on the ground and is not restricted by the installation position of the speaker; and the speaker has both sound amplification and visual guidance functions, and is particularly suitable for use in large indoor spaces.

[0021] The floor speaker of the present invention is divided into two parts: a base box and a main shell. All functional components are integrated on the main shell. The base box is first pre-buried and installed at the ground position to be installed, and then the main shell can be quickly and conveniently installed on the base box by bolts, thereby realizing the rapid construction of the floor speaker array.

[0022] A transmission frame is arranged inside the floor speaker of the present invention, and the circular ring-shaped supporting edge of the transmission frame is fitted together with the bottom surface of the edge of the vibration sound-generating plate. The vibrator is installed on the bottom surface of the middle mounting plate of the transmission frame. The vibrator can transmit vibration to the vibration sound-generating plate through the transmission frame to realize vibration sound generation. Another function of the transmission frame is to form a spatial structure with the vibration sound-generating plate to enhance the structural strength of the sound-generating plate so that it can withstand higher loads.

[0023] In addition, the present invention also provides a vibration sounding plate vibration isolation sealing ring that cooperates with the transmission frame and the vibration sounding plate. The vibration sounding plate vibration isolation sealing ring is sleeved on the periphery of the transmission frame and the vibration sounding plate to provide elastic support for the transmission frame and the vibration sounding plate, so that the transmission frame and the vibration sounding plate are stably installed on the main shell and also have the ability to vibrate.
