    Abstract: A speaker is disclosed herein. And, in configuring a magnetic circuit of the speaker, unlike the vertical polarity alignment of the related art speaker, the polarities of the magnet are configured to be horizontally aligned, and a vibration system is configured on an inner side surface of the vertically configured magnetic circuit. Accordingly, by having the magnetic circuit encircle the vibration system, unlike in the related art speaker, wherein the height of the speaker corresponds to a sum of the thickness of the vibration system and the thickness of the magnetic circuit, the speaker may be configured only by using the height of the magnetic circuit. Furthermore, by being capable of reducing the height of the speaker, even if the volume of the magnet is being increased, the sound effect of the speaker may be enhanced.
