In prior art, in the process of a cross-country car of exploitation, find that, when blast the horn, vehicle body, bearing circle, clutch pedal can experience vibration.By carrying out reason investigation to this problem, find that loudspeaker are directly connected on vehicle body front cross rail by a rigid support, because be that the exciting force of loudspeaker when loudspeaker work that is rigidly connected directly can pass to each subassembly by being rigidly connected of each parts, finally pass to the parts that human body can touch.
Utility model content
During in order to overcome blast the horn in prior art, miscellaneous part can experience this technical matters of vibration, and the utility model provides a kind of horn trumpet assembly and automobile.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model provides a kind of horn trumpet assembly, comprises the speaker body for sounding, and described horn trumpet assembly also comprises:
Horn bracket, its one end is fixed in described speaker body, and its other end is connected with vehicle body;
Dynamic vibration absorber, is installed on the surface of described horn bracket;
Described dynamic vibration absorber comprises: shell and inner core, and described inner core inserts in described shell, and with described shell interference fit; Described inner core is connected with described horn bracket by a joint pin; Described inner core is that elastomeric material is made.
Furthermore, in described horn trumpet assembly, described shell is the cylindrical shape with certain wall thickness, and described inner core is cylinder, described inner core axially inserting in described shell from one end of described shell along described shell.
Furthermore, in described horn trumpet assembly, described joint pin is arranged on the axle center of described inner core, and the inside of described inner core is inserted along the axis of described inner core in one end of described joint pin, the other end of described joint pin and described horn bracket weld together.
Furthermore, in described horn trumpet assembly, a bolt hole is offered at the two ends of described horn bracket respectively, and described horn bracket is fixed with described speaker body and described vehicle body respectively by bolt and is connected.
Furthermore, in described horn trumpet assembly, the material of described shell is metal, and the material of described inner core is rubber.
The utility model additionally provides a kind of automobile, comprises the horn trumpet assembly as above described in any one.
The beneficial effects of the utility model are: horn trumpet assembly of the present utility model, the energy of the nearly all loudspeaker excitation of resonance absorption is produced by the dynamic vibration absorber installed, the vibration of the loudspeaker that automobile miscellaneous part is delivered to is dropped to minimum, add the travelling comfort of car load.
Accompanying drawing explanation
Fig. 1 represents the structural representation of horn trumpet assembly in the utility model embodiment;
Fig. 2 represents the structural representation of the dynamic vibration absorber of horn trumpet assembly in the utility model embodiment.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
Shown in seeing figures.1.and.2, the utility model provides a kind of horn trumpet assembly, and comprise the speaker body 1 for sounding, horn trumpet assembly also comprises: horn bracket 2, and its one end is fixed in speaker body 1, and its other end is connected with vehicle body; Dynamic vibration absorber 3, is installed on the surface of horn bracket 2; Dynamic vibration absorber comprises 3: shell 31 and inner core 32, and inner core 32 inserts in shell 31, and with shell 31 interference fit; Inner core 32 is made for elastomeric material.
Because each parts are subject to, loudspeaker excitation is excessive creates forced vibration, deals with problems so can only start with from vibration source and bang path.Wherein horn bracket 2 connects the bridge between speaker body 1 and vehicle body, that is, horn bracket 2 be transmitting vibrations bang path.So install the dynamic vibration absorber 3 of a frequency the same as loudspeaker excitation frequency on horn bracket 2.Wherein the shell 31 of dynamic vibration absorber 3 and inner core 32 connect together, and inner core 32 adopts elastomeric material, by the collocation of adjustment shell 31 and inner core 32, i.e. and the resonance frequency of adjustable dynamic vibration absorber 3.
Dynamic vibration absorber frequency adjustment is according to formula
wherein f is the resonance frequency of dynamic vibration absorber, and K is inner core rigidity, and m is outer cover quality.According to formula, we can adjust the frequency that we want.
When such speaker body 1 works, loudspeaker frequency of operation is the same with dynamic vibration absorber frequency, produce the energy of the nearly all loudspeaker excitation of resonance absorption according to resonance principle dynamic vibration absorber, pass to the inevitable obviously reduction of energy of vehicle body and miscellaneous part according to conservation energy, problem is resolved.
Shell 31 is for having the cylindrical shape of certain wall thickness, and inner core 32 is cylinder, inner core 32 axially inserting in shell 31 from one end of shell 31 along shell 31.Such setting is convenient for changing different inner cores 32.During replacing, only need inner core 32 to eject from shell 31 then to carry out changing.The material of shell 31 is metal, and the material of inner core 32 is rubber or elastoplast.Certain shell and inner core also can select other materials to make, and the combination of materials of metal and rubber is the combination of the optimum that cost and shock attenuation result consider.
Inner core 32 is arranged a joint pin 33, joint pin 33 is arranged on the axle center of inner core 32, the inside of inner core 32 is inserted along the axis of inner core 32 in one end of joint pin 33, the other end and the horn bracket 2 of joint pin 33 are welded and fixed, joint pin 33 and horn bracket 2 is made to form integrative-structure, be conducive to transmission of vibration, considerably increase the shock attenuation result of dynamic vibration absorber 3.
A bolt hole is offered at the two ends of horn bracket 2 respectively, and horn bracket is fixed with speaker body 1 and vehicle body respectively by bolt 4 and bolt 5 and is connected.Such design, the Assembly &Disassembly for whole horn trumpet assembly provides conveniently.
The utility model additionally provides a kind of automobile, comprises the horn trumpet assembly of as above any one.
It should be noted that, this automobile is the automobile comprising above-mentioned horn trumpet assembly, and the implementation of above-mentioned horn trumpet assembly embodiment is equally applicable in the embodiment of this automobile, also can reach identical technique effect, not repeat them here.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
