Background

A loudspeaker, also called a loudspeaker, is a transducer device that converts an electrical signal into an acoustic signal, and the quality of the loudspeaker greatly affects the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound.

The speaker itself is generally composed of a magnet, a tray frame, a gasket, a sound disc and the like. Although the basic user demand can be satisfied to current loudspeaker disk rail, the drawback is also very obvious, and its main table has: in the practical use process of the loudspeaker, external vibration and other acting forces may directly act on the loudspeaker, and the disc frame and other parts may loosen in the past, which is one of the main reasons for poor sound quality of the loudspeaker.

In order to solve the problem, the application provides a effectual loudspeaker plate rail of antidetonation.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in the figure, a effectual loudspeaker plate rail frame of antidetonation is provided, including

support body

1, 1 side of support body is fixedly connected with locating piece 2 all around respectively, the extension rod 3 that fixedly connected with stretches out downwards is distinguished to the bottom surface of locating piece 2 all around, sealing ring 4 has been cup jointed in the middle part activity of extension rod 3, the fixed top surface that cup joints at drum 5 in the outside of sealing ring 4, sealing plug 6 has been cup jointed at the middle part of 5 inner chambers of drum, and the top surface of sealing plug 6 and the bottom interconnect of extension rod 3, the bottom surface fixedly connected with base plate 7 of drum 5, the fastening spiro 8 has been cup jointed to the left and right sides of base plate. When support body 1 self received external impact effort, synchronous activity about support body 1 can be followed to sealing plug 6 to the activity of sealing plug 6 can drive the synchronous change of atmospheric pressure about the drum 5 is inside, and this just forces sealing plug 6 to realize resetting to the middle part activity, has realized the shock attenuation effect to device self at the sealing plug 6 in-process to the middle part activity, is the feasible major structure support of this device principle.

In this embodiment, the length of the extension rod 3 is equal to the length of the cylinder 5, and the bottom end of the cylinder 5 is fixedly connected to the middle of the top surface of the base plate 7. In the device in-service use process, its extension rod 3 can be in the drum 5 activity from top to bottom, through adopting the design of certain extension rod 3 of length value and drum 5 for sealing plug 6 can fully move about to the top surface or the bottom surface of drum 5 inner chamber, ensures the realization of shock attenuation effect.

As shown in fig. 2, the sealing plug 6 itself is rounded at the sides, and the diameter of the sealing plug 6 is equal to the diameter of the inner wall of the cylinder 5. Because the diameter value of sealing plug 6 is equal to the diameter value of the inner wall of cylinder 5, so the sealing plug 6 can be tightly attached to the inner wall of cylinder 5, and the sealing performance between cylinder 5 and sealing plug 6 is also ensured on the basis of not hindering the up-and-down movement of sealing plug 6.

It should be noted that the fastening screw rings 8 are divided into four groups, and the number of each group is two, the two fastening screw rings 8 respectively penetrate through the upper and lower sides of the substrate 7, and each group of fastening screw rings 8 is respectively sleeved on the two sides of the substrate 7 in a symmetrical manner. The periphery of the side face of the frame body 1 is respectively provided with the fastening spiral ring 8, so that the device can be positioned in the equipment through the fastening spiral ring 8.

The utility model discloses a theory of operation and use flow: when the device is used, the device can be fixed at the position needing to be installed through the fastening spiral rings 8 on the periphery. When effort such as external vibrations produced the impact to device self, device self can vibrations in step thereupon, support body 1 at this moment can transmit the effort of activity for sealing plug 6 through extension rod 3, when sealing plug 6 was in drum 5 middle part, the atmospheric pressure of both sides is balanced about drum 5, at the sealing plug 6 in-process of upwards perhaps activity downwards, the unequal state of pressure can appear in the meeting of both sides about drum 5, thereby force sealing plug 6 to realize resetting to the middle part activity, the shock attenuation effect to support body 1 self has been realized.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
