Description
Technical field
The utility model is related to loudspeaker technical fields, and in particular to a kind of Cupula fixed type loudspeaker.
Background technology
Loudspeaker is product common in people's daily life, and farther for amplifying sound, propagating, species is more,
It can be divided into hand-held loudspeaker, waist-mounted type loudspeaker, adsorption-fixing type loudspeaker etc. according to occupation mode.Adsorption-fixing type amplifies
Device is typically to be adsorbed megaphone on metal object surface such as car body using strong magnet, but magnet is directly and body surface
Contact easily generates friction with body surface when placing, removing, scratches mounting surface, causes installation surface damage, and magnet is inhaled
Attached loudspeaker can only be fixed on metal surface, and fixation can not be just played on the mounting surface of other materials.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of suckers that will not scratch mounting surface and strong adsorption force to consolidate
Fixed pattern loudspeaker.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of Cupula fixed type loudspeaker is designed, including megaphone, is arranged on the mounting base of the megaphone bottom,
At least one vacuum cup is fixed in the mounting base；
The vacuum cup includes conical sucker wall, cylindrical cavity is equipped on the top of the sucker wall, described
Cavity top is equipped with screw hole, and connector is equipped in the cavity, and the connector includes matching with the cavity size
Circular gasket, lead screw is equipped on the gasket, the lead screw extended to through the screw hole outside the cavity,
The lead screw is structure as a whole with the gasket；
Correspondence position is fixed with the nut to match with the lead screw, the vacuum cup and institute in the mounting base
It states and is connected by the lead screw with nut between mounting base.
In the above-mentioned technical solutions, loudspeaker uses the fixed mode of sucker, can be fixed on the mounting surface of unlike material
On, overcome the defects of loudspeaker of magnetic adsorption can only be fixed on magnetic metal surface and easily scratch mounting surface.Vacuum
It is connected, can be set in the lower part of a megaphone more using lead screw and nut between sucker and the mounting base of megaphone
A vacuum cup makes its adsorption capacity stronger, and when one of sucker loosens, other suckers are still fixed, will not mutual shadow
It rings, by the slip between lead screw and nut, the high and low position between each vacuum cup and mounting base can be adjusted, make every
A sucker can be bonded mounting surface.
Preferably, the mounting base is triangular structure, is separately installed at the position at three angles of the triangle
One vacuum cup.
Preferably, the mounting base is quadrilateral structure, is separately installed at the position at four angles of the quadrangle
One vacuum cup is also installed in the center position of the quadrangle there are one vacuum cup.
Preferably, the mounting base is circular configuration, and in the bottom circle centre position installation of the mounting base, there are one vacuum to inhale
4-6 vacuum cup has been mounted equidistant around the center of circle in disk.
Preferably, strong magnetic iron plate is equipped in the lower part of the cavity internal gasket, the flat thin magnet is pasted with the gasket
It is fixed together.When loudspeaker is mounted on magnetic metal surface, flat thin magnet can be combined with vacuum cup and play dual suction
Attached effect, the air inside vacuum cup are extruded, and mounting surface are touched at the top of sucker wall, at this moment in vacuum cup cavity
Flat thin magnet also generates an adsorption capacity to mounting surface, plays the role of dual absorption, meanwhile, flat thin magnet is arranged on vacuum cup
Cavity in, across the top surface of sucker wall between flat thin magnet and mounting surface, do not contacted directly with mounting surface, flat thin magnet will not be generated
The problem of scratching mounting surface.Together with flat thin magnet is pasted and fixed on the gasket of lead screw lower part, flat thin magnet and gasket, spiral shell can be made
Screw becomes one structure, and makes the connection between vacuum cup and mounting base more secured.
Preferably, the vacuum cup is rubber material.
The beneficial effects of the utility model are：
The utility model installs fixed loudspeaker using vacuum cup, and loudspeaker can be fixed on to a variety of mounting surfaces
On, solve the fixed loudspeaker of traditional magnet-type can only be fixed on magnetic metal surface and magnet easily by mounting surface draw
The problem of hindering.The utility model is easier for installation, the scope of application is wider, can also be by being set in the apex cavity of vacuum cup
It puts flat thin magnet and plays the role of dual absorption, be more firmly mounted loudspeaker.
