PURPOSE: A speaker is provided to prevent slanted sound vibration, to improve low-tone sound, and to prevent the deterioration of adhesives or damage of the vibrating plate due to heat by inducing sound waves released from the speaker with a sound wave inducer. CONSTITUTION: If an electric current is input to a voice coil(26), a bobbin(28) vibrates a vibrating plate(30). A yoke(38) with a sound wave path(38a) is installed with a determined spacing inside the bobbin(28). A sound wave inducer(40) is installed at the sound wave path(38a) of the yoke(38) with a determined spacing from the yoke(38) and the vibrating wall(30). The sound wave inducer(40) induces sound waves forwardly and backwardly.
