DETAILED DESCRIPTION OF THE INVENTION This invention relates to the improvement of the
Sukika Unitz) K which is used in a snowway or 3-way speaker system, and in particular,
reappears in the high blue range and the middle and high mounts. In the same ddP Yavinet K11ll
(a loudspeaker system constituted by 7 when D loudspeakers are mounted, radiation from the
front of the loudspeaker into the cabinet, ?gt't ? ? * i ? ? E41110X1 ? ? ? 110 ?01 j (,)
11 [ In order to prevent one problem, a high-pitched or medium-high pitched speaker, which
generally has a small pack chamber volume, is often provided with a batter cover that WIlFs the
propagation of O-pressure from blue- If a cover is provided, connect the terminals of the speaker
and the terminals provided on the pack cover via the lead wires III! Because of this, it takes a lot
of procedures and time for this work, and it is easy to cause inconveniences such as hearing the
polarity. This invention is a% O made for the purpose of eliminating the above-mentioned
inconvenience due to the provision of a pack cover and K, and one embodiment thereof will be
specifically described below with reference to the drawings. Loudspeakers indicated by reference
numeral 1 in IIII are for high-pitched sound% L <for middle-to-high-pitched sound, and are
usually mounted on a baffle plate of a suitable cabinet in a speaker unit (not shown) that receives
low-frequency reproduction. This Suki cano has a frame 3 supporting a cone-shaped diaphragm
1, and a pair of plate gins and INK votes! The Mevin tK-wound voice coil 9 which has an outershaped through-hole through a damnet 6 and a -O1P, and which is integral with the diaphragm
1, is placed in the magnetic gap of the magnetic path. positioned. Then, both ends of the pois coil
90 are respectively connected to a pair of terminals 10 (one fist is shown to 11111) attached to
the frame 3 via a lead @ 11, and the i-th terminal 10K is bent On the other hand, the lead wire / J
having lime strength is fixed by means such as soldering, and the tip of the drawer 11 / J extends
rearward of the frame 30. On the other hand, the batter force N- / 3 arranged on the back side of
the speaker has a bottomed cylindrical shape constituted by an integral form of a synthetic resin
such as polyvinyl chloride, l-ethylene or glystyrene, and its bottom wall ) Through the play of the
magnetic circuit 7) tK screwed in and attached iii * to the speaker / by the mounting melt l. Then,
in this state 111, the pack cover tsOII gait is in close contact with the frame 30 porcelain rim
back portion INK, and by this K, a batter chamber 15 having a predetermined volume is formed
in the speaker tovit * @.
A step / JJI having a ridge face parallel to the bottom surface is formed on a portion of the pack
cover no in the i (1) ?rinse?, and on the edge of the O step / J, the tooth 2s II K A thin portion
13b as shown is formed. The ?-O thin-walled portion 13b closes one end of a through hole / 34
formed between the guiding portion / 3c which stands by a predetermined length from the inner
surface of the step portion tSa and the pack cover / J inner surface. In the process of placing the
cover / 3 at a predetermined position with respect to the speaker /, the tip of the high-rigidity
lead @ l co is broken by the tip jllK, and as a result, the tip of the lead @ / J has a step / 3 m
Center out towards the outside from the surface. As described above, according to the present
invention K, according to the speaker terminal to6c, the rigid high-drawout @ / jt attachment is
carried out by K, the operation only for setting the batter cover 13 to the predetermined position
, The leader / 2 part of the fault is centered on the outside of the pack power bar / 30 and this
central end can be used as a terminal or a possible stone, hence the pack cover / 3 is mounted, so
that it is very easy to use The air tightness of the pack chamber 130 is also maintained at a high
level. U) ?Simplified description of 411111 tlg is a longitudinal sectional view showing one
