Description
Technical field
The present invention relates to a kind of car horn, specifically a kind of loudspeaker on automobile.
Background technology
The reason for car horn is easily damaged has, and long-time excess load driving loudspeaker, loudspeaker can be because of overheat and loudspeaker
Burn out, because the temperature rise of coil, makes some structure divisions produce fusing, ruptures or burn, the temperature of normal use lower coil
Degree just has 180 degrees Celsius；Mechanical failure, the driving loudspeaker of excess load cause paper disc to move out scope and simultaneously separated with coil,
Or coil and coil holder separation, paper disc flanging or loudspeaker bracing ring are torn, any of the above situation can make once occurring
Loudspeaker break down.When flanging or bracing ring are torn, coil will rub with them, because paper disc component can not be suitably
To be suspended in midair in center, perhaps small rupture, which just starts not feel, comes, but after a period of time, when crack becomes big, loudspeaker
Will and then be broken.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of loudspeaker on automobile
.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of loudspeaker on automobile, including shell, cone, magnet, wire, soft iron stem, the first voice coil loudspeaker voice coil and the second voice coil loudspeaker voice coil,
The inside of the shell is fixed with cone, and the enclosure is provided with two magnet, and the cone bottom is provided with soft iron core
Post, the soft iron stem surface are provided with the first voice coil loudspeaker voice coil and the second voice coil loudspeaker voice coil, and wire is provided with by soft iron stem on the cone,
First voice coil loudspeaker voice coil and the installation of the second voice coil loudspeaker voice coil interval.
Preferably, the soft iron stem and wire are electric connection.
Preferably, the diameter of first voice coil loudspeaker voice coil is smaller than the diameter length of the second voice coil loudspeaker voice coil.
Beneficial effects of the present invention：The present invention is simple in construction, and convenient to be used on automobile, voice coil loudspeaker voice coil has two kinds so that loudspeaker
Audio it is more preferable, become apparent from, trumpet structure connection is compact, and stability is stronger, and the first voice coil loudspeaker voice coil is convenient and the second voice coil loudspeaker voice coil
It is used cooperatively, service life is long, and shell can be supported and stably to magnet.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the overall structure diagram of the present invention.
In figure：1st, shell, 2, cone, 3, magnet, 4, wire, 5, soft iron stem, the 6, first voice coil loudspeaker voice coil；7th, the second voice coil loudspeaker voice coil.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Refer to shown in Fig. 1, a kind of loudspeaker on automobile, including shell 1, cone 2, magnet 3, wire 4, soft iron core
Post 5, the first voice coil loudspeaker voice coil 6 and the second voice coil loudspeaker voice coil 7, the inside of the shell 1 are fixed with cone 2, and the shell 1 is internally provided with two magnetic
Iron 3, the bottom of cone 2 are provided with soft iron stem 5, and the surface of soft iron stem 5 is provided with the first voice coil loudspeaker voice coil 6 and the second voice coil loudspeaker voice coil,
Wire 4, the voice coil loudspeaker voice coil 7 of the first voice coil loudspeaker voice coil 6 and second interval installation are provided with by soft iron stem 5 on the cone 2.
As a kind of technical optimization scheme of the present invention, the soft iron stem 5 and wire 4 are electric connection.
As a kind of technical optimization scheme of the present invention, the diameter length of the diameter of first voice coil loudspeaker voice coil 6 than the second voice coil loudspeaker voice coil 7
It is small.
A kind of conversion equipment of sound is converted into the use of the present invention, loudspeaker are a kind of electric energy in fact, when different electricity
When sub- energy reaches coil, coil produces the magnetic field interaction of a kind of energy and magnet, and this interaction causes paper disc to vibrate, because electric
Sub- energy changes at any time, and the coil of loudspeaker can move forward or backward, therefore the paper disc of loudspeaker will be moved and then, this this action
The density degree of air is set to produce change and produce sound.
Beneficial effects of the present invention：Beneficial effects of the present invention：The present invention is simple in construction, convenient to be used on automobile, sound
Circle has two kinds so that the audio of loudspeaker is more preferable, becomes apparent from, and trumpet structure connection is compact, and stability is stronger, the first sound
Circle is convenient and the second voice coil loudspeaker voice coil is used cooperatively, and service life is long, and shell can be supported and stably to magnet.
This is not limited to, any change or replacement expected without creative work, should all cover the guarantor in the present invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
