摘要： In the speaker of the invention, a circular outer magnet type magnetic circuit 8, and a diaphragm 13 to which a circular voice coil 14 driven by the circuit is fixed are held on a rectangular frame 1. The circular outer magnet type magnetic circuit 8 is configured by: a yoke 9 in which a rectangular flange 9b is disposed in one end of a circular center pole 9a; a plate-like magnet 10 which has a circular center hole 10a, which is placed with forming a circular annular gap around the yoke center pole 9a, and which has a rectangular outer shape that is substantially identical with the outer shape of the yoke flange 9b; and a circular annular pole piece 11 which is substantially equal in inner diameter to the magnet center hole 10a, in which the outer diameter is substantially equal to short side dimensions of the yoke flange 9b and the magnet 10, and which cooperates with the yoke flange 9b to clampingly hold the magnet 10. A circular magnetic gap 12 is formed between the yoke center pole 9a and the pole piece 11. The magnet 10 is split into two portions in a center area in the longitudinal direction.

摘要： The invention relates to an electroacoustic transducing device in which a sound generated by an electroacoustic transducer to be incorporated in a case of a portable electronic apparatus is emitted through a sound hole disposed in a side face of the case and situated on a lateral side of the electroacoustic transducer. Sound holes are disposed in front and side faces of the electroacoustic transducer, respectively. The acoustic resistance which affects vibration of the diaphragm is reduced, and the diaphragm can easily vibrate. Even when the same driving power is applied, the sound pressure of the electroacoustic transducer is improved as compared with the prior art.
摘要翻译：本发明涉及一种电声转换装置，其中由电声换能器产生的声音转换器装在便携式电子装置的壳体中，通过设置在壳体的侧面的声孔发射，并位于电声换能器。声孔分别设置在电声换能器的前面和侧面。影响隔膜振动的声阻减小，隔膜容易振动。即使当施加相同的驱动功率时，与现有技术相比，电声换能器的声压也得到改善。
