    摘要： A speaker device is provided, the speaker device ensuring a simplified structure and enhancing the positional precision of a vibrator to an actuator, thereby improving sound quality.
    The speaker device includes an actuator that operates according to a driving signal, a spring holder having a coupling portion to which the actuator is coupled, the spring holder at least being partially elastically deformable, and a plurality of vibrators connected together via the spring holder, the vibrators vibrating according to the operation of the actuator. In this configuration, the plurality of vibrators are connected together via the spring holder and the actuator is coupled to the coupling portion of the spring holder. Connection of the plurality of vibrators as well as coupling of the actuator, therefore, is achieved by the spring holder. This enhances the positional precision of the vibrators to the actuator. As a result, as structural simplification is ensured, the positional precision of the vibrators to the actuator is enhanced to allow an improvement in sound quality.
