Abstract
The utility model provides a kind of vehicle-mounted megaphone, including megaphone, link, elastic component, lead, magnetic absorption part, megaphone is fixedly connected with link, slidable fit has lead on link, lead lower end is provided with magnetic absorption part, and elastic component is provided between magnetic absorption part and link, when automobile is in more severe road conditions condition downward driving, elastic component can weaken the vibrations of vehicle-mounted megaphone, will not because automobile jolt rock cause vehicle-mounted megaphone to drop.
Description
Technical field
It the utility model is related to automobile electronics technical field, and in particular to a kind of vehicle-mounted megaphone.
Background technology
Megaphone is commonly called as loudspeaker, have it is fixed have hand-held, be mainly used to expand the volume of people.Need to transmit in people
During some disclosed information, megaphone is usually used；Although fixed megaphone is convenient, its propagation distance has
Limit, and hand-held megaphone, because the speed of people is slower, the efficiency that its information is propagated is relatively low, and people are in order that information
Propagate faster, megaphone is usually used when ride bicycle or open automobile, to accelerate information spread speed,
But people are inconvenient, and usually bring danger to driving when driving using hand-held megaphone.
The U's of Authorization Notice No. CN 202602893, authorized announcement date 2012.12.12 Chinese utility model patent is public
Onboard wireless megaphone is opened, its magnetic absorption chassis interior contains magnet, and turntable is rotatably connected in magnetic absorption bottom
Seat top, megaphone are fixed on turntable top.Because it is using directly by setting a monoblock below megaphone
The mode of magnet realizes that megaphone is fixed with roof, in vehicle travel process, because road surface is uneven, can cause automobile
Rocked during traveling, megaphone also easily drops because rocking, and shock resistance is poor.
Utility model content
The purpose of this utility model is to provide a kind of vehicle-mounted megaphone, to solve vehicle-mounted megaphone in the prior art
The problem of shock resistance is poor.
To achieve the above object, technical scheme is used by the utility model solves its technical problem：Originally it is vehicle-mounted to amplify
Loudspeaker include megaphone, magnetic absorption part, and megaphone is fixedly connected with link, and slidable fit has guiding on link
Post, lead lower end are provided with magnetic absorption part, and elastic component is provided between magnetic absorption part and link.
Preferably, magnetic absorption part has three and the distribution triangular in shape of its position.
The elastic component is helical spring.
The beneficial effects of the utility model are：This vehicle-mounted megaphone is provided with bullet between magnetic absorption part and link
Property part, when because vehicle rocks cause vehicle-mounted megaphone to rock when, the amplitude that vehicle-mounted megaphone rocks can be reduced, can
The amplitude that effectively avoids rocking by vehicle-mounted megaphone is excessive to cause vehicle-mounted megaphone to drop.
Further, the magnetic absorption part of this vehicle-mounted megaphone has three and the distribution triangular in shape of its position, so
The torque that adsorption piece gives megaphone pulling force can be increased, allow vehicle-mounted megaphone bear it is violent rock, avoid because
Amplitude that vehicle-mounted megaphone rocks is excessive to cause vehicle-mounted megaphone to drop.
Brief description of the drawings
Fig. 1 is the structural representation of vehicle-mounted megaphone.
Embodiment
The utility model is further illustrated with reference to embodiment：
The embodiment of vehicle-mounted megaphone of the present utility model, as shown in figure 1, described vehicle-mounted megaphone bag
Include megaphone 1, link 2, elastic component 3, lead 4, magnetic absorption part 5.The megaphone 1 is fixed with link 2 to be connected
Connect, will not be changed with the relative position ensured between megaphone 1 and link 2, the link 2 is slided with lead 4
Dynamic to coordinate, i.e., link 2 can slide relative to lead 4, and the lower end of lead 4 is provided with magnetic absorption part 5, the magnetic
Adsorption piece 5 is used to adsorb the top cover in automobile, elastic component 3 is provided between the magnetic absorption part 5 and link 2, when link 2
When being slided relative to lead 4, elastic component 3 is compressed or discharged.
The top cover of automobile is generally steel making, and magnetic absorption part 5 has magnetic, due to magnetic action, whole vehicle-mounted expansion
Mixer can be adsorbed firmly on roof top.
The elastic component 3 of the present embodiment is helical spring.
The lead 4 of the present embodiment is hex bolts, and hex bolts passes through link 2, and in the end of thread of hex bolts
Magnetic absorption part 5 is fixedly mounted.
The magnetic absorption part of the present embodiment has three, the position distribution triangular in shape of three magnetic absorption parts.
The megaphone of the present embodiment is achieved a fixed connection with link by rivet.
In other embodiment of the present utility model, elastic component 3 can also be to be made using rubber or other elastomeric materials
Elastomer block.
