Abstract: The present invention discloses a moving-coil electroacoustic transducer, which is bar-shaped, and comprises a vibration system. The vibration system comprises a vibration diaphragm, a bar-shaped acoustic coil, an acoustic coil support, and two plucked members. The acoustic coil sleeves the acoustic coil support and is combined with the vibration diaphragm through the acoustic coil support. The acoustic coil support is integrally thrilled, and comprises an acoustic coil mounting portion located in the middle, plucked member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion. In such a design, by using the integrally formed acoustic coil support, and disposing the plucked member mounting portions at the two ends of the acoustic coil support, a support portion is disposed between two long-axis edges of the acoustic coil mounting portion, and the acoustic coil support can be formed integrally, so that the problems of biased vibration and deformation on the long-axis side is solved, and meanwhile the manufacturing process is simplified, thereby making the manufacturing simpler.

Abstract translation: 本发明公开了一种棒状的动圈式电声换能器，包括振动系统。 振动系统包括振动膜，棒状声线圈，声线圈支架和两个拔出构件。 声学线圈套住声线圈支架，并通过声线圈支架与振动膜组合。 声学线圈支架整体激动，并且包括位于中间的声学线圈安装部分，位于两端的拔除构件安装部分和设置在声学线圈安装部分的两个长轴边缘之间的支撑部分。 在这种设计中，通过使用整体形成的声线圈支架，并将拔出构件安装部分设置在声线圈支架的两端，支撑部分设置在声线圈安装部分的两个长轴边缘之间， 可以一体地形成声线圈支撑体，解决了长轴侧的偏置振动和变形的问题，同时简化了制造工艺，从而使制造更简单。

Abstract: The present disclosure discloses a loudspeaker and a method for improving directivity of a sound of a loudspeaker, a head-mounted device and a method for improving a sound effect of a head-mounted device. The loudspeaker comprises: a housing, a magnetic circuit unit that is provided within the housing and is for generating a magnetic force, a voice coil that vibrates by the magnetic force, and a vibrating diaphragm that in response to the vibration of the voice coil vibrates and generates a sound; wherein the loudspeaker further comprises a curved-surface extension structure; the curved-surface extension structure connects to the vibrating diaphragm, and radiating the sound generated by the vibrating diaphragm into a predetermined directivity range.
