Description

전자 손목시계의 경보장치Alarm of electronic watch

제1a도는 본 고안의 종단면도.Figure 1a is a longitudinal cross-sectional view of the present invention.

b도는 본 고안의 저면도.b is a bottom view of the present invention.

제2도는 종래고안의 종단면도.2 is a longitudinal sectional view of a conventional design.

본 고안은 전자 손목시계의 뒤뚜껑에 형성된 진동판에 경보음 발생용 피에조 엘렉트릭 엘레멘트(PIEZO ELECTRICITY ELEMENT)를 착설하여 경보음이 발생되게 하는 전자손목시계의 경보장치에 관한 것이다.The present invention relates to an alarm device for an electronic watch that installs a PIEZO ELECTRICITY ELEMENT for alarm sound generation on a diaphragm formed on the back cover of an electronic watch.

종래의 전자손목시계 경보장치는 모듈(MOdule)과 구멍이 뚫린 뒤 뚜껑사이에 피에조 엘렉트릭부저를 장치하여 묘둘에서 발생된 가청교류신호(Audio A.C Siginal)를 피에조 엘렉트릭 부저의 양극에 가하여 발생된 경보음이 기계의 뒤 뚜껑에 천공된 통공을 통하여 외부로 전달되도록 되어 있으므로 시계의 두께가 두꺼워 투박스러울 뿐만 아니라 경보음의 진동에 따라 뒤 뚜껑에 부착된 피에조 엘렉트릭 부저의 접착부위가 떨어지는 경향이 있어 방수효과가 저하되고 조립 공정상의 불편한 점이 많았다.Conventional electronic watch alarm device is equipped with a piezo electric buzzer between the module (MOdule) and the hole after the hole is punctured, the alarm sound generated by applying the audio AC signal generated from the tomb to the anode of the piezo electric buzzer This machine is designed to be transmitted to the outside through the perforated hole on the back cover of the machine, so the watch is thick and not only two-boxy, but also the adhesive area of the piezo electric buzzer attached to the back cover falls due to the alarm sound. Was lowered and there were many inconveniences in the assembly process.

본 고안은 이러한 점을 감안하여 고안한 것으로 시계 뒤 뚜껑에 형성된 진동판의 내면에 피에조 엘렉트릭엘레멘트를 직접 착설하여뒤 뚜껑에 형성된 진동판이 부저역활The present invention was devised in view of this point, and the piezoelectric element was directly installed on the inner surface of the diaphragm formed on the lid of the watch.

전자손목시계(1)내에 모듈(2)이 삽착되고 뒤 뚜껑(3)이 나합된 것에 있어서 뒤 뚜껑(3)에 얇게 형성된 진동판(3')의 내면에 공지된 피에조 엘렉트릭 엘레멘트(4)를 착설하며, 모듈(2)과 피에조 엘렉트릭 엘레멘트(4)를 전도스프링(5)으로 연결하여 시계의 뒤 뚜껑 자체가 피에조 엘렉트릭 부저가된 것으로 미설명부호 6은 탄접편이다.The known piezoelectric element 4 is installed on the inner surface of the diaphragm 3 'thinly formed on the rear lid 3 in which the module 2 is inserted into the electronic watch 1 and the rear lid 3 is screwed together. The back cover of the watch itself becomes a piezo electric buzzer by connecting the module 2 and the piezo electric element 4 with the conduction spring 5, and reference numeral 6 is a contact piece.

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다. 모듈(2)에서 발생되는 경보용 교류 신호의 1극은 전도스프링(5)에 의하여 뒤 뚜껑(3)의 진동판(3')에 착설된 피에조 엘렉트릭 엘레멘트(4)에 전달되고, 다른 타 극은 탄접편(6)에 의하여 뒤 뚜껑(3)에 전달되어 뒤 뚜껑(3)의 진동판(3')과 피에조 엘렉트릭 엘레멘트(4)가 하나의 부하가 되어 전원 루우프(LOOP)를 형성하여 시계(1)의 모듈(2)에서 발생되는 신호에 따라 피에조 엘렉트릭 엘레멘트(4)의 수축작용에 의하여 진동판(3')이 진동하면서 경보음을 발생시켜 들을수 있게한 것으로 시계 뒤 뚜껑(3)에 진동판(3')을 형성하여 진동판(3')에 피에조 엘렉트릭 엘레멘트(4)를 직접 착설한 뒤 뚜껑(3)에서 경보음이 발하게 되므로 시계내에 피에조 엘렉트릭 부저를 내장할때 보다 시계의 두께가 얇아저 미려하게 보이고 뒤 뚜껑에 구멍을 뚫을 필요가 없어서 방수효과를 최대로 높일수 있는 유용Referring to the effect of the present invention as described above is as follows. One pole of the AC signal for alarm generated in the module 2 is transmitted to the piezoelectric element 4 mounted on the diaphragm 3 'of the rear lid 3 by the conduction spring 5, and the other pole is It is transmitted to the rear lid 3 by the ball contact piece 6 so that the diaphragm 3 'and the piezo electric element 4 of the rear lid 3 become one load to form a power supply loop, thereby making the clock 1 The diaphragm 3 'vibrates due to the contraction of the piezoelectric element 4 in response to a signal generated by the module 2 of FIG. ')' Form the piezo electric element (4) directly on the diaphragm (3 ') and the alarm sound is emitted from the lid (3), so when the piezo electric buzzer is embedded in the watch, the thickness of the watch is thinner and more beautiful You don't need to drill holes in the rear lid Useful to raise
