DESCRIPTION JPS56155583
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial cutaway perspective view of an onvehicle speaker according to the present invention, and FIG. 2 is a perspective view showing a
state where it is mounted on a lighter parcel tray. DESCRIPTION OF SYMBOLS 1 ... cabinet, 11 ...

The present invention relates to an on-vehicle speaker unit, and more particularly to an onvehicle speaker unit with reduced attenuation of high-frequency sound. Among the in-car
speaker units, two-way type ones usually adopted the coaxial type are many, and when the
speaker unit is attached to a car passenger parcel tray, the speaker axis is on the rear window
glass Because it crosses 1- & (Pu x, y? 音 The sound from this Suki Kaenit is K to hit that glass. In
the front of the omnidirectional low band, the passenger has to listen to the sound attenuated by
the glass, although there is no problem. In addition, even if a speaker system in the form of a
coaxial type car-mounted speaker unit, fl, t, a woofer unit and a tweeter unit are assembled on
the baffle plate so that the sound axis of the person is parallel, the mounting beam may be
mounted. Damping against yer window glass is similar to that of the coaxial speakers unit.
Therefore, in the in-vehicle two-way speaker unit configured by losing the woofer unit and the
tweeter unit to the baffle plate, the idea of Jin tried not to cross the sound axis of the tweeter unit
from the rear to the in-glass. Therefore, without making the sound of the tweeter unit attached to
the baffle plate 11 perpendicular to the baffle plate 11 substantially parallel to the plane
including the baffle plate, in other words, the sound axis at the front surface 11 of the tweeter
unit It is characterized in that it is constructed so as to be able to intersect with the 紘 baffle plate
so that high-range sound can be directly emitted to the passenger compartment. The details of
this invention will be described below with reference to the attached drawings Ka. First, a cabinet
of an in-vehicle speaker unit having a symbol iFi bagful number // is shown in FIG. It is attached.
The tweeter unit 3 is housed in the accommodation cabin J / 4 'of the tweeter unit provided in
the フ ル フ ル フ ル フ ル ///, L acoustic lens talk is attached to the forward direction (car

interior II) of this accommodation cabin 3 / There is. The three tweeter units in the storage cabin
31 are mounted so that the sound axes thereof are directed directly to the passenger
compartment, and directivity control is performed by the acoustic lens 32 so that the radiated
sound waves are transmitted to the passenger Kl in the passenger compartment. Will be
configured. Since the vehicle-mounted speaker unit of this invention is configured as described
above, there is no directivity of the sound wave radiated from the 3-woofer unit when the
speaker airt is attached to the car passenger parcel tray RKil. The sound #IL from the tweeter
unit 3 is radiated to the room directly and is not attenuated because the sound axis does not
cross the baffle plate at the front of the tweeter unit. I can listen to it.
As is apparent from the above description, according to the vehicle-mounted speaker unit of the
present invention, the baffle plate on which the woofer unit is attached is used for the passenger
in a single room iI! Direction of the sound wave emitted by the tweeter unit to reach the highrange sound waves The company is electrically controlled to face the company cabin, so it is
beautiful without listening to the high-frequency sound reflected and attenuated by the rear
window glass You can play a good sound.
