DESCRIPTION JPH0520494
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
embedded speaker for car audio, and more particularly, to an embedded speaker for car audio
which enables only a tweeter unit to be mounted at a location different from a main unit.
[0002]
2. Description of the Related Art An example of a conventional coaxial type embedded speaker is
shown in FIG. As shown in the figure, tweeter units 18 were attached to the center of the speaker
unit main body 17, and they were covered with a speaker grill 19. Such embedded speakers are
often attached to the bottom of the vehicle door as shown in FIG.
[0003]
[Problems to be Solved by the Invention] When the above-mentioned conventional embedded
speaker is mounted at the lower part of the vehicle door, the high-pitched sound with high
directivity is obstructed by an obstacle such as the listener's foot There was a drawback that it
was difficult to reach the listener. This invention was made in view of the above-mentioned point,
and the purpose is to provide an embedded speaker for car audio which makes it possible to
move the tweeter part to any place without an obstacle. It is in.

SUMMARY OF THE INVENTION The car audio embedded speaker according to the present
invention is such that the tweeter unit can be fitted into a speaker grill that covers the speaker
unit main body.
[0005]
Also, a pillar is provided at the center of the speaker unit main body, a terminal is provided at the
tip of the pillar, and when the tweeter unit is fitted to the speaker grille, wiring is made to the
tweeter unit by the terminal of the tip of the pillar. It was constructed in
[0006]
Further, the speaker attachment according to the present invention can be fitted with a tweeter
unit which can be fitted to the speaker grille, and when the tweeter unit is fitted, the position
corresponding to the terminal provided on the pillar of the speaker unit It is comprised so that it
may wire to a tweeter unit by the terminal provided in.
[0007]
According to the embedded speaker for car audio of the present invention, the tweeter unit fitted
to the speaker grill is removed, and fitted to the speaker fitting attached at an arbitrary position
in the car. The tweeter unit is wired by the terminal.
By moving the tweeter unit to a place where there is no obstacle in this way, the sound quality
deterioration of the high range can be avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A car audio embedded speaker
according to an embodiment of the present invention will be described with reference to the
drawings.
FIG. 1 is an exploded perspective view showing a car audio embedded speaker according to an
10-05-2019

embodiment of the present invention.
A pillar 2 is provided at a central portion of the speaker unit main body 1 in which the woofer
unit is incorporated, and terminals 6, 6 are provided at the tip of the pillar 2 in a protruding
manner. The speaker grill 3 is fastened so as to cover the speaker unit body 1. When the speaker
grill 3 is fastened to the speaker unit body 1, the terminals 6, 6 project from the hole 5 provided
at the center of the speaker grill 3. Slide fittings 4, 4 are provided on both sides of the hole 5 of
the speaker grill 3, and the tweeter unit 7 is slidably fitted in the slide fittings 4, 4. At this time,
the terminals 6, 6 are in pressure contact with the terminals provided on the back surface of the
tweeter unit 7 so that the tweeter unit 7 is wired.
[0009]
Reference numeral 8 shown in FIG. 1 denotes a terminal board, which is shown in detail in FIG.
Terminals 9 and 9 in the figure are terminals to which the output cable of the power amplifier is
connected, and are connected to the woofer unit inside the speaker unit main body 1, and the
terminal 6 shown in FIG. Connected to six. 10, 10 are terminals for wiring when the tweeter unit
7 is moved, and are connected to the terminals 6, 6
[0010]
FIG. 3A is a perspective view showing a speaker attachment according to an embodiment of the
present invention. Rails 12a and 12a are provided on the speaker attachment 12 so that the
tweeter unit 7 can be slidably attached, and terminals provided on the back surface of the
tweeter unit 7 when the tweeter unit 7 is attached Terminals 6, 6 to be pressure-welded are
provided. The terminals 6, 6 are connected to the cable 14, and connectors 15, 15 connected to
the terminals 10, 10 shown in FIG. The tweeter unit 7 is provided with holes 13 and 13 so as to
be screwed into any place in the vehicle compartment. By using the fixture 16 shown in FIG. 3B,
when the tweeter unit 7 is attached to the rear tray, the tweeter unit 7 can be directed to the
front of the passenger compartment.
[0011]
With the above construction, the speaker fixture 12 is fastened at an arbitrary position in the
10-05-2019

vehicle compartment to connect the connectors 15, 15 to the terminals 10, 10, and the tweeter
unit 7 is removed from the speaker grill 3 to mount the speaker fixture 12. The tweeter unit can
be moved to an unobstructed place by attaching to FIG. 4 shows an example in which the tweeter
unit 7 is moved to the upper part of the vehicle door.
[0012]
According to the embedded speaker for car audio of the present invention, the tweeter unit can
be moved from the main body and arranged in a place without obstacles by a simple structure, so
that the sound quality deterioration of the high range is avoided. Be
[0013]
Further, since tweeter units can be easily replaced, tweeter units having different characteristics
can be provided to enjoy various sounds.
In that case, the bodies of units with different characteristics can be distinguished by color.
