[0029] Referring to FIGS. 1[0029] a to 1 e and FIG. 2, a sound producing device 10 has a case 11 and a cover 12 which are made of plastic. The cover 12 has a plurality of sound discharge holes 13, and the underside of the case 11 also has a plurality of sound discharge hole 13 a as shown in FIG. 2.
[0030] A connector [0030] 17 according to the present invention is integrated with the case 11 at the molding of the case 11.
[0031] Referring to FIGS. 3[0031] a through 4 e, the connector 17 has a box shape comprising an upper plate 17 a, lower plate 17 b, side plates 17 c, 17 d and rear plate 17 m. In the front of the connector 17, an insertion opening 17 n is formed. The upper plate 17 a has a pair of windows 17 e, and the lower plate 17 b has a pair of windows 17 f. A pair of cantilever elastic contacts 18 made of elastic metal are embedded in the rear plate 17 m at the molding of the connector 17 and appear in the windows 17 e. Each of the elastic contacts 18 has a contacting projection 18 a upwardly projected at a front end portion and extends in an insertion direction of a slider 19 (FIG. 3).
[0032] On the outer walls of the side plates [0032] 17 c and 17 d, there is formed hooks 17 g and 17 h, and rib projections 17 i and 17 j, respectively. Each of the hooks and rib projections are arranged in the slider insertion direction. As shown in FIG. 4a, each of the hooks 17 g and 17 h is positioned at a position in an upper half location. Each of the rib projections 17 i and 17 j is elongated a whole height of the side plate 17 c (17 d).
[0033] Referring to FIGS. 4[0033] d and 4 e, three guide ribs 17 k are provided on the lower plate 4 b, extending in the slider insertion direction for guiding a flexible substrate 20 (FIG. 3). As shown in FIGS. 4a and 4 c, there is formed a slant 17 l on the lower plate 17 b at the opening 17 n for guiding the insertion of the flexible substrate 20.
[0034] Referring to FIG. 2, on the underside of the case [0034] 11, a pair of terminals 14 are embedded in the case and connected to ends of a coil of a buzzer provided in the case 11. Each of the elastic contacts 18 and the corresponding terminal 14 are formed from a metal plate including intermediate lead so as to be connected through the intermediate lead.
[0035] Referring to FIGS. 5[0035] a to 5 d the slider 19 comprises a pressure portion 19 a, an introducing portion 19 b, adjacent the pressure portion 19 a having an upward slant formed on the underside thereof, and a pair of side plates 19 c and 19 d confronting the opposite sides of the pressure portion 19 a.
[0036] As shown in FIG. 5[0036] b, the pressure portion 19 a is positioned in an upper half range. On inside walls of the side plates 19 c and 19 d, hooks 19 e and 19 f, ribs 19 g and 19 h are extending from the hooks are formed. These portions 19 e, 19 f, 19 g and 19 h are positioned in a lower half range as shown in FIGS. 5b, 5 c. On both sides of the base portion of the slider 19, projections 19 k and 19 l are provided, outwardly projecting as a pair of knobs for extracting the slider 19 from the connector 17.
[0037] The connector [0037] 17 and the slider 19 are supplied to a portable telephone manufacturer. The substrate 20 is inserted in the connector 17 by the manufacturer.
[0038] Referring to FIGS. 6[0038] a through 6 e showing the inserting operation of the slider 19, the slider 19 is inserted in the connector 17 from the opening 17 n. At the hooks 17 g and 17 h, the side plates 19 c and 19 d are expanded by the engagement of the hooks 19 e and 19 f, so that the hooks 19 e and 19 f of the slider 19 get over the hooks 17 g and 17 h and enter substrate introducing positions 17 p.
[0039] The inserting of the slider [0039] 19 is stopped at the substrate introducing position 17 p shown in FIGS. 3a and 6 b where a gap is formed between the introducing portion 19 b and the contacting projection 18 a as shown in FIG. 3a.
[0040] Thereafter, the flexible substrate [0040] 20 is inserted in the connector 17 from the opening 17 n as shown in FIG. 3b. At that time, the flexible substrate 20 is guided by the slant 17 l and guide ribs 17 k. The substrate passes through the gap between the introducing portion 19 b and the contacting projection 18 a. As shown in FIG. 3b, the substrate 20 and the slider 19 are inserted to an innermost position of the connector 17, while the hooks 19 e and 19 f of the slider 19 get over the rib projections 17 i and 17 j. At the innermost position, the pressure portion 19 a of the slider 19 presses the substrate 20 to the elastic contacts 18. Consequently, the connecting projections 18 a of the elastic contacts 18 are contacted with terminals on the flexible substrate 20. Thus, the sound producing device 10 is connected to the flexible substrate 20. At the innermost position, the hooks 19 e and 19 f of the slider 19 engage with outside of the rib projections 17 i and 17 j, thereby the slider is secured to the connector.
[0041] In order to remove the flexible substrate [0041] 20, if the slider 19 is pulled out from the position of FIGS. 3b and 6 c to the position of FIGS. 3a and 6 b, the substrate can be removed. At that time, since the hooks 19 e and 19 f engage with the hooks 17 g and 17 b, the slider 19 is not removed.
[0042] In accordance with the present invention, since the substrate is connected to the sound producing device by inserting the substrate in the connector, the connecting operation is very easy. [0042]
[0043] While the invention has been described in conjunction with preferred specific embodiment thereof, it will be understood that this description is intended to illustrate and not limit the scope of the invention, which is defined by the following claims. [0043]
