摘要： Disclosed is a speaker with a built-in direct current motor for selectively generating sound and vibration, which includes: a speaker part, a direct current motor part, and a frame (160). The speaker part has a yoke (150) having a hole formed at the center thereof, a first ring-shaped magnet (140) mounted on the top surface of the peripheral portion of the yoke, a ring-shaped upper plate (130) mounted on the top surface of the first magnet, a vibration plate (110) fixedly mounted to the top surface of the upper plate at the circumferential end thereof, and a generally cylindrical voice coil (120) attached to the bottom surface of the vibration plate. The direct current motor part has a lower plate (240) coupled to the bottom surface of the peripheral portion of the yoke, a flexible printed circuit board disposed on the lower plate, a second ring-shaped magnet (230) mounted on the top surface of the lower plate, a rotary shaft (210) positioned one end thereof on the hole of the yoke and positioned the other end thereof on the hole of the center of the flexible printed circuit board, and an eccentric rotor (220) rotatably mounted on the rotary shaft. According to the present invention, sound or/and vibration is/are selectively outputted from portable equipment such as a cellular phone requiring a vibration function.

摘要： According to the present invention, the horizontal sections of the components of the condenser microphone are formed in an elliptical or a running track shape while the area of a diaphragm responding to sound pressure is maintained to be equal to or larger than a certain size, thus preventing a reduction in sensitivity to sound pressure as well as occupying the minimum internal space of each of various electronic products that trend toward miniaturization and thinness. Furthermore, a circular raised portion is formed at the center of the horizontal part of the casing, or a groove having an arcuate, triangular or rectangular section is formed on the horizontal part of the casing, so that the flatness of the casing and the gap between a diaphragm and a backplate are uniformly maintained, thus preventing the variations in the characteristics of the condenser microphone.

摘要翻译：根据本发明，电容麦克风的部件的水平部分形成为椭圆形或跑步轨道形状，而响应于声压的隔膜的面积保持在一定大小以上，因此防止对声压的敏感性降低，以及占据趋向于小型化和薄型化的各种电子产品的最小内部空间。此外，在壳体的水平部分的中心处形成圆形凸起部分，或者在壳体的水平部分上形成具有弓形，三角形或矩形部分的凹槽，使得壳体的平直度和间隙均匀地保持在隔膜和背板之间，从而防止电容麦克风的特性的变化。
