In a kind of preferred embodiment of the invention, the contact making device includes coaxially arranged upper contact, lower contact And spring, the upper contact are connect with the support column, the lower contact is connect with the steering wheel, and the spring is set to institute It states between upper contact and the lower contact.

In a kind of preferred embodiment of the invention, rubber mat is provided between the upper contact and the support column.

In a kind of preferred embodiment of the invention, the floating the cover is greater than institute relative to the pressing stroke of steering wheel State the triggering stroke of upper contact and the lower contact.

In a kind of preferred embodiment of the invention, the floating the cover is relative to the pressing stroke of steering wheel.

In a kind of preferred embodiment of the invention, reinforcement is provided between the support column and the floating the cover Muscle.

In a kind of preferred embodiment of the invention, what the shape of the floating the cover and 4 contact making devices surrounded etc. Waist is trapezoidal corresponding.

The beneficial effects of the present invention are: the utility model structure is simple, easy to use, by that will be set to square plate 4 contact making devices on the disk body of center are arranged as isosceles trapezoidal structure and guarantee the center of the center disk body of its center and square plate It is overlapped, draws electrocution devices work to be needed pressing force so as to be effectively reduced, 15N is reduced to by original 40N, from having The usage comfort for improving this smaller particular client groups of strength such as women is improved to effect, while but also user's pressing is floating Dynamic the cover any position pressing can trigger loudspeaker.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

The invention discloses a kind of loudspeaker trigger architectures, from the attached Fig. 1 and 2 of description of the invention comprising for pacifying In the floating the cover 1 of steering wheel, the conducting of loudspeaker circuit is triggered by pressing floating the cover 1, including be set to center disk body 4 On for the contact making device 2 of loudspeaker to be connected and is set in floating the cover 1 for pushing the support column 3 of contact making device 2, contact dress Set 2 number it is corresponding with the number of support column 3, the position of contact making device 2 is corresponding with the position of support column 3, It is characterized by: contact making device 2 is 4,4 contact making devices 2 are located at four vertex of an isosceles trapezoid, in the isosceles trapezoid The heart is overlapped with the center of floating the cover 1, and the symmetry axis of the isosceles trapezoid is conllinear with the symmetry axis of floating the cover 1, the isosceles trapezoid 4 vertex be located at and the 10 o'clock direction at the isosceles trapezoid center at 2 points, 5 points, 7 points.Contact making device 2 includes coaxial cloth Upper contact 2.1, lower contact 2.2 and the spring 2.3 set, upper contact 2.1 are connect with support column 3, lower contact 2.2 and center disk body 4 Connection, spring 2.3 are set between upper contact 2.1 and lower contact 2.2.Rubber mat is provided between upper contact 2.1 and support column 3. Floating the cover 1 is greater than the triggering stroke of upper contact 2.1 and lower contact 2.2 relative to the pressing stroke (about 3mm) of center disk body 4 (about 1.5mm)；Contactor gap is less than the stroke of pressing, therefore is easy to triggering loudspeaker ring, and the distribution of 4 points, protects Loudspeaker can be triggered at any point by having demonstrate,proved, and pressing force, between 15N-25N, user's use feeling is fine.Floating the cover 1 Pressing stroke relative to center disk body 4 is.Reinforcing rib is provided between support column 3 and floating the cover 1.The shape of floating the cover 1 Shape is corresponding with the isosceles trapezoid that 4 contact making devices 2 surround.

It may be noted that floating the cover 1 of the invention, center disk body 4, contact making device 2 are the prior art, specific structure can To refer to Chinese patent CN205220504U, CN204340857U, CN202016432U and CN101909939A.Core of the invention Heart inventive point is the position of electrocution devices 2, therefore can arbitrarily trigger the contact in the prior art dress that loudspeaker pipe 2 are set to all belong to the scope of protection of the present invention.

More than it should be understood that, only specific embodiment of the present utility model, but the protection scope of the utility model It is not limited thereto, anyone skilled in the art can be thought easily in the technical scope disclosed by the utility model The change or replacement arrived, should be covered within the scope of the utility model.
