The present invention relates to a speaker device having a thermal relay for protecting a speaker
and an excessive input display element, which makes it extremely easy to mount these
components and furthermore maintains the degree of hermeticity of the speaker cabinet So that
it can be used. Conventionally, when excessive current flows in the speaker, automatically circuit
it! ! "1" - "" - "1" '' '' 'Ln 7 +' 'with a thermal relay that protects the speaker by disconnecting it and
a LED for excessive input display that lights up when this thermal relay operates. , Q2 However,
this thermal relays and LEDs have been throttled separately in the cabinet, together with the
complexity of their mounting structure, their blowing work is very troublesome, and the degree
of sealing of the chic speaker cabinet is also sufficient There is a problem that it can not be kept
high. FIGS. 1 to 3 show such a conventional spraying device. Thermal relay 1 is shown in FIG. 1
(a). (B) As shown in l (C), a reset button 1b for manually returning the circuit to the upper surface
of the case 1a is protruded, and two pairs of terminals 1c, 1c are protruded on the lower surface
of the case 1a. When installing this thermal relay, the spot facing 2a and the through hole 2b are
provided in the front plate 2 of the cabinet, the upper and lower portions of the thermal relay 1
are sandwiched between the sealed packing 3 and the spray fitting 4, and the spray fitting 4 is
screwed to the screw 6 So as to tighten the front plate 2. On the other hand, in the case of
throttling the LED, as shown in FIG. 2), a circular seat 21 and a circular through hole 2 d are
provided on the front plate 2 of the cabinet, and fixed and dense 3 - closed 3, a rectangular
pocket 2e, a circular pocket 2f and a circular through hole 2q are provided in the front plate 2 as
shown in FIG. 3, and the LEDe , The printed circuit board 8 is fixed to the bottom surface of the
spot facing 2e with the screw 9 so that the sealant adhesive 7 is applied around the LEDe so that
it can be pushed into the through hole 2F It was. However, in this way: (1) Since the thermal
relay 1 and the LEDe must be throttled separately, the number of working steps is large. (2) Parts
can not be replaced because they are fixed with the adhesive 7. (3) When the front plate 2 is
constituted by a particle board, the strength of the screw 5, 90 is guaranteed for about 3
intestines from the surface layer, but when the counterbore is formed to the middle layer portion,
the density of the particle board is low, The spray strength by screw 5.9 weakens. "7 ') (4) As
shown in Fig. 3, two counterbores 7 - L of square shape and circular shape!
In order to provide 2e and 2f, it is necessary to machine 2 - - - - - - - - - - - - 4, so it is difficult to
achieve dimensional accuracy. There were various problems. The present invention provides a
speaker device which solves such a conventional problem. DESCRIPTION OF THE PREFERRED
EMBODIMENTS An embodiment of the present invention will be described below with reference
to FIGS. 4 to 7. In FIGS. 4 to 7, reference numeral 10 denotes a front plate constituting the
speaker cabinet, numeral 10a denotes an oblong through hole formed in the front plate 10,
numeral 10b denotes a spot formed on the periphery of the through hole 10a, numeral 11
denotes A display panel provided on the surface of the front plate 1 o, 12 a rubber molded
product press-fitted into the through hole 10 a, 1 6 a thermal relay and IID similar to the
conventional one wrapped in a rubber molded product, 1 g It is connected to terminal 1 C of
thermal relay 1 and terminal 6 a of LEDe or is a single wire. As shown in FIG. 6 and FIG. 6, the
rubber molded article 12 includes holding bodies 12 a, 12 a divided in two in the thickness
direction and holding bodies 12 a. 12a projectingly provided on the arms 12a, 12a, a connecting
portion 12 'connecting the arms 12b, 12b independently, and a connecting portion 12c
protruding from the arms 12b, 12b, Protrusions 12 d and 12 d used as a finger hook when
attaching and detaching the rubber molded article 120, positioning recessed portions 12 e and
convex portions 12 f formed in the respective arm portions 12 b and 12 b, a thermal relay
housing portion 12 g wrapping the thermal relay 1 without gaps 12g, the reset button insertion
portions 12h, 12h and the terminal insertion portion 121 12i connected to the thermal relay
storage portions 12g, 12g, the insertion portions 12j, 12j of the LED 6, the insertion portion 12
of the terminal 6a of the LED 6 12, the lead portions 12 .mu., 121 of the lead wires 13, the ribs
12 tM, 12 n for further improving the sealing and reclosing, the permeability of the front plate
10 A tapered surface 12o to facilitate insertion into 10a, a concave portion 12p and the
protrusion 12q for positioning and is formed integrally with the rubber. Therefore, as shown in
FIG. 6 (the thermal relay 1.!: LED 6 previously connected by the lead 413 as shown in FIG. 6), the
thermal relay housing portion 12 g of the rubber molded product 12 opened as shown in FIG. 6
LED housing section 12 j 2 ░ '- 1 =), and then 2 minutes of rubber molded article 12 -,. When
the 6-split holders 12a, 12a are brought into tight contact with each other, the thermal relay 1
and LEDe are wrapped in the rubber molded product 12 in a state of being almost completely
sealed as shown in FIG. 6 (C).
Thereafter, when the rubber molded product 12 is press-fitted into the through hole 10a of the
front plate 1o, the rib 12n makes a close contact with the bottom surface of the counter bore 10b
as shown in FIG. 4, and the rib 12m makes contact with the rear edge of the through hole 10a
The cabinet is kept in a state of being kept in contact with the cabinet, so that there is almost no
gap between the front plate 10 and the rubber molded article 120, and the cabinet is kept at a
very high degree of sealing. When exchanging one part or the like, a finger is hooked on the
protruding part 12 d of the arm part 12 b and the rubber molded part 12 is pulled out from the
through hole 10 a. Further, in order to form the oblong through hole 12a and the gutter 12b in
the front plate 10, as shown in FIG. 7, a router 14 having two stages 14a, 14b of different
diameters is used, and it is rotated Therefore, as shown by arrows, if you do loo, you can
simultaneously pierce hole 10a and spot facing 12b to 2, и "1 ': f4j,!:" 14 ░ и F? ?????? 2)
As described above, the present invention wraps the thermal relay and the display element 7
element one by one with a single rubber molded article without gaps. Since this rubber molded
product is press-fitted into the mounting hole of the speaker cabinet with no gap, it is extremely
easy to mount the thermal relay and the display element, and it is possible to maintain the
speaker cabinet at a high tightness Immersion effect is obtained.
