Detailed description of the invention
For making those of ordinary skill in the art be more clearly understood from the purpose of this utility model, technical scheme
And advantage, below in conjunction with drawings and Examples, this utility model is further elaborated.
With reference to shown in Fig. 1, in a kind of embodiment of the present utility model, the automobile A of this band loudspeaker installation position
Post includes: cylinder 10, which is provided with groove 11, and described groove 11 is provided with the first boss 12 and second
Boss 13, described first boss 12 is provided with the first installation position 14 for installing the first loudspeaker 16, described
Described second boss 13 is provided with the second installation position 15 for installing the second loudspeaker 17.
Front-seat driver's seat or front passenger's seat either it is sitting in due to people, the most any between cylinder 10 and human ear
Barrier, signal can directly, intactly pass in ear, therefore by installing the first loudspeaker on cylinder 10
16 and second loudspeaker 17 so that sound effect more preferably.Groove 11 is set on cylinder 10, so that the
The top of one boss 12 and the second boss 13 is not higher than the surface of cylinder 10, so that the first loudspeaker 16
It is installed on after first installation position the 14, second loudspeaker 17 are installed on the second installation position 15 non-bulging in cylinder 10
Surface, thus the effect of protection loudspeaker can be played, prevent loudspeaker impaired, also play visual
Aesthetic.This utility model by be provided with on cylinder 10 install the first loudspeaker 16 the first boss 12 and
Second boss 13 of the second loudspeaker 17 is installed, reduces the requirement of the professional technique to workmen so that loudspeaker
Installation effect is not by man's activity, more convenient.
Due to the number of degrees pointing to angle of loudspeaker, as long as being somewhat varied from, sense of hearing arises that the biggest going out
Enter, wherein point to angle and refer to the opening direction of loudspeaker and the angle of vertical.Therefore want to hear real " standard
Sound really ", it is necessary to be accurately positioned to the sensing angle of loudspeaker.
Shown in Fig. 2, in a kind of embodiment of the present utility model, in order to make driver drive a car
Time obtain more preferable sense of hearing, position centered by driver head position, all loudspeaker on car steering position
Opening direction all towards centre bit, such that it is able to restore clear, a three-dimensional sense of hearing.
Point to angle and include the first sensing angle, the second sensing angle, the 3rd sensing angle and the 4th sensing angle, specifically
Ground, in the present embodiment, sets up rectangular coordinate system in space, described driver's head with an O for initial point
Position is the some D in rectangular coordinate system in space；Point A is the first loudspeaker 16 of automobile left side, crosses some A
Being the vertical CD of vertical line AC in a C, connecting AD, ∠ A is the first sensing angle；Point B directly over some O
For the second loudspeaker 17 of automobile left side, cross some B and be the vertical DO of vertical line BO in an O, connection BD, ∠ B
It it is the second sensing angle.Further, the first sensing angle ∠ A and second can be obtained according to arctan function to point to
The number of degrees of angle ∠ B.
Described arctan function expression formula is formula (1):
Arctan (tanx)=x, x ∈ (-pi/2, pi/2) (1)；
In formula (1), x is required angle, and tanx is the tangent value of x.
By measuring line segment AC, line segment CD, line segment BO, the length of line segment DO, draw:
Tan ∠ A=DC/AC (2)；
Tan ∠ B=DO/BO (3)；
(2) formula is substituted into (1) formula.The number of degrees drawing the first sensing angle ∠ A are:
∠ A=arctan (tan ∠ A)
=arctan (DC/AC)
(2) formula is substituted into (1) formula.The number of degrees drawing the second sensing angle ∠ B are:
∠ B=arctan (tan ∠ B)
=arctan (DO/BO)
In above-mentioned rectangular coordinate system in space, some E is the first loudspeaker 16 ' of car right side, crosses some E and does vertical line
The vertical DG of EG is in a G, and connecting ED, ∠ E is the 3rd sensing angle；Point F is the second loudspeaker of car right side
17 ', cross a some F and be the vertical DH of vertical line FH in a H, connecting FD, ∠ F is the 4th to point to angle.
By measuring line segment EG, line segment DG, line segment FH and the length of line segment DH, draw:
Tan ∠ E=DG/EG (4)；
Tan ∠ F=DH/FH (5)；
(4) formula is substituted into (1) formula, show that the number of degrees of the 3rd sensing angle ∠ E are:
∠ E=arctan (tan ∠ E)
=arctan (DG/EG)
(5) formula is substituted into (1) formula.Show that the 4th number of degrees pointing to angle ∠ F are:
∠ F=arctan (tan ∠ F)
=arctan (DH/FH)
In this utility model above-described embodiment, on car steering position centered by driver head position
Position, in other embodiments of the present utility model, it is also possible to position centered by the position at center, automobile front row, from
And the number of degrees pointing to angle of accurate calculation loudspeaker.
Preferably, in embodiments more of the present utility model, first points to angle ∠ A and second points to angle ∠ B
Between the number of degrees differ 3 °～20 °, the 3rd points to the number of degrees difference that angle ∠ E and the 4th points between the ∠ F of angle
3 °～20 °, such that it is able to the loudspeaker effectively solved on the cylinder 10 of both sides pass to the sound of centre bit because of
There is time difference or phase contrast and cause the technical problem that sense of hearing is fuzzy.
Preferably, in embodiments more of the present utility model, first points to angle ∠ A and second points to angle ∠ B
Between the number of degrees differ 5 °, the 3rd points to angle ∠ E and the 4th points to the number of degrees between the ∠ F of angle and differs 5 °,
So that the sound that driver hears is apparent, have more third dimension.
In embodiments more of the present utility model, the first loudspeaker 16 are bass horn, and the second loudspeaker 17 are
Loudspeaker.In another embodiment of the present utility model, the first loudspeaker 16 are loudspeaker, the second loudspeaker
17 is bass horn.
Preferably, the shell bottom of the first loudspeaker 16 is provided with the buckle fastened with the first installation position 14, makes
Obtain the first loudspeaker 16 the most firm with the connection of the first installation position 14.
Preferably, the shell bottom of the second loudspeaker 17 is provided with the buckle fastened with the second installation position 15, makes
Obtain the second loudspeaker 17 the most firm with the connection of the second installation position 15.
Preferably, the cylinder 10 of band loudspeaker installation position, by injection moulding integrated molding, has saved manufacturing time and system
Make cost.
The foregoing is only preferred embodiment of the present utility model, rather than this utility model is done any in form
Restriction.Those skilled in the art can impose the change of various equivalent on the basis of above-described embodiment and change
