종래의 진동모터는 제1도에 나타낸 바와 같이, 하부브라켓(1)에 샤프트(2)와 브라시(11)를 고정하고, 착자된 마그네트(12)를 하부브라켓(1)에 부착시키며, 편심된 로타(13)에 전자자코일(15)과 코뮤테이터(14)를 부착하여 샤프트(2)에 결합하여 형성한다.In the conventional vibration motor, as shown in FIG. 1, the shaft 2 and the brass 11 are fixed to the lower bracket 1, and the magnetized magnet 12 is attached to the lower bracket 1, and eccentric. The electromagnetic coil 15 and the commutator 14 are attached to the rotatable 13 to be coupled to the shaft 2 and formed.

이러한 종래의 진동모터는 편심된 로타(13)가 회전하면서 전기자기에 의하여 진동이 발생된다.In this conventional vibration motor, the eccentric rota 13 rotates to generate vibration by the electric magnet.

그러나, 이러한 종래의 진동모터는 진동발생 장치로서만 사용될 뿐 음량신호 기능이 필요할 경우, 즉 무선전화기, 페이저 등에 별도의 음량신호 기능을 설치하여야하는 문제점이 발생되었다.However, such a conventional vibration motor is used only as a vibration generating device, when a volume signal function is required, that is, a problem arises in that a separate volume signal function must be installed in a radio telephone or a pager.

따라서 본 발명은 상기한 문제점을 해소하기 위한 것으로, 그 목적은 진동모터내에 부저를 일체화하여 사용자가 진동 또는 부저로 사용할 수 있도록한 부저내장형 진동모터를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to provide a buzzer built-in vibration motor that integrates a buzzer in a vibration motor so that a user can use it as a vibration or a buzzer.

위와 같은 목적을 달성하기 위하여 본 발명은 마그네트 하부에 편심된 로타를 형성한 진동부와; 상기 진동부의 상부에 철편을 형성하고, 철편 상부에 부저코일을 형성한 부저부로 구성함을 그 기술적 구성상의 기본 특징으로 한다.In order to achieve the above object, the present invention includes a vibrating unit that forms a rota eccentric in the lower magnet; Forming an iron piece on the upper portion of the vibrating portion, and a buzzer portion formed with a buzzer coil on the iron piece is characterized in that the basic features on the technical configuration.

위와 같이 구성된 본 발명의 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

제2도 내지 제4도에 나타낸 바와 같이, 진동부(10)은 브라켓(1)의 중앙에 형성된 샤프트(3)에 환형의 마그네트(12)를 부착하여 형성하고, 상기 마그네트(12)의 하부에 위치하도록 편심된 로타(13)를 샤프트(2)에 결합하여 형성한다. 상기 샤프트(2)의 로타(13)결합위치위에 코뮤테이터(14)를 부착하여 형성하고, 코뮤테이터(14)의 상부에 브라시(11)를 결합하여 형성한다.2 to 4, the vibrator 10 is formed by attaching an annular magnet 12 to the shaft 3 formed in the center of the bracket 1, and the lower portion of the magnet 12 Rota 13 eccentric to be located in the coupling to the shaft (2) is formed. The commutator 14 is attached to the rotatable 13 coupling position of the shaft 2, and the brass 11 is coupled to the upper part of the commutator 14.

부저부(20)는 상기 진동부(10)의 마그네트(12)상부에 착자극수 및 착자위치를 변경시키기 위한 철편(22)부착하고, 상기 철편(22)을 좌우 대칭되는 부채골 형상으로 형성한다. 상기 철편(22)의 가장자리에는 고정홀더(21)를 형성하고, 상기 철편(22)의 중심부분에 환형의 부저코일(23)를 형성한다. 또한, 상기 부저코일(23)과 고정홀더(21)의 상부에 진동판(24)를 부착하여 형성한다.The buzzer 20 is attached to the iron piece 22 for changing the number of magnetizing poles and the magnetizing position on the magnet 12 of the vibrating portion 10, the iron piece 22 is formed into a fan bone shape symmetrically do. A fixing holder 21 is formed at the edge of the iron piece 22, and an annular buzzer coil 23 is formed at the central portion of the iron piece 22. In addition, the buzzer coil 23 and the fixing holder 21 is formed by attaching the diaphragm 24.

이러한 본 발명의 모터에 사용되는 마그네트(12)는 4극이 필요하고 부저에 사용되는 마그네트(12)는 2극이 필요하므로서 상기 마그네트(12)의 2극을 덮도록 철편(22)을 부착하여 마그네트(12)상면을 4극에서 2극으로 변환한다. 따라서, 직류전원이 인가되면 전기자 코일(15)이 형성된 편심된 로타(13)가 회전되어, 진동상태가 되고, 교류 전원 또는 펄스 신호가 인가되면 부저코일(23)에 의하여 진동판(24)이 진동하면서 부저음을 발생시킨다.The magnet 12 used in the motor of the present invention requires four poles, and the magnet 12 used for the buzzer needs two poles, so that the iron pieces 22 are attached to cover the two poles of the magnet 12. The upper surface of the magnet 12 is converted from 4 poles to 2 poles. Therefore, when DC power is applied, the eccentric rotatable 13 in which the armature coil 15 is formed is rotated to be in a vibrating state, and when the AC power or pulse signal is applied, the diaphragm 24 vibrates by the buzzer coil 23. While generating a buzzer.

이상에서 살펴본 바와 같이 본 발명은 진동모터의 샤프트 중앙에 마그네트를 형성시켜 마그네트의 하부에 진동부를 형성하고 마그네트의 상면은 철편을 부착하여 마그네트를 4극에서 2극으로 변화시켜 부저부를 형성하므로서 직류전원 또는 펄스 및 교류전원을 인가하면, 진동 또는 부저음을 발생시킬 수 있는 것이다.As described above, the present invention forms a magnet in the center of the shaft of the vibration motor to form a vibration part at the bottom of the magnet, and the upper surface of the magnet attaches iron pieces to change the magnet from 4 poles to 2 poles to form a buzzer. Alternatively, when pulses and AC power are applied, vibration or buzzer sounds may be generated.
