    摘要： When an amplitude of vibration of a first diaphragm of a first speaker unit vibrated by applying a first and a correction AC signals having a frequency in a first frequency band to the first speaker unit is equalized to that of a second diaphragm of a second speaker unit vibrated by applying a second AC signal being the same as the first AC signal to the second speaker unit being the same as the first speaker unit attached to a closed type cabinet having the same internal volume as a speaker cabinet, a sound pressure reproduced by the first diaphragm is equal to or lower than that reproduced by the second diaphragm when a third AC signal having a frequency of a minimum resonance frequency or higher of the closed type cabinet determined by the internal volume thereof and the caliber of the second speaker unit is applied to the second speaker unit.

    摘要： The present invention relates to a speaker box module, and particularly relates to a loudspeaker that produces sound through the mechanical vibration generated by electromagnetic force and a manufacturing method therefor. The loudspeaker comprises a speaker box module which comprises a speaker, a passive radiator and a speaker box panel, wherein a mounting hole is arranged in the speaker box panel; the speaker is arranged in the mounting hole and is integrated with the speaker box panel by means of insert injection molding; a secondary mounting hole is arranged in the speaker box panel at one side of the mounting hole; and the passive radiator is arranged in the secondary mounting hole and is integrated with the speaker box panel by means of insert injection molding. The loudspeaker is small and thin, structurally simple, and enhances bass, and can be used as a built-in speaker or an external speaker for modern tablet computers or smart phones, and the like. In order to ensure that the speaker box has excellent acoustic effect, the present invention uses an insert injection integrated manufacturing process, which ensures maximum acoustic effect of the speaker box while greatly reducing man-hours and thereby increasing production efficiency.

    摘要： An electronic device (1) is provided with a piezoelectric element (30), a panel (10) holding the piezoelectric element (30), and a housing (60) holding the panel (10) and transmitting vibration through the panel (10). The electronic device (1) causes the panel (10) to generate vibration sound that is transmitted by vibrating a part of a human body. The electronic device (1) includes a stiffness varying portion (62, 63) in which the stiffness of the housing (60) varies.
