    • PURPOSE: A portable speaker is provided to output abundant sound volume using the interference of the sound outputted from a plurality of sound source parts. CONSTITUTION: A portable speaker comprises a plurality of sound source parts(70), and a diffraction plate(90). A plurality of sound source parts output the sound. The output directivity of the sound from the second sound source part(75) is changed to cause interference with the sound outputted from the first sound source part(71) among the diffraction plates. The diffraction plate is arranged by facing with the sound output side of the second sound source part. The first sound source part and the second sound source part are arranged to have different sound output directivity.
    • 目的:提供便携式扬声器,以利用从多个声源部分输出的声音的干扰来输出丰富的音量。 构成:便携式扬声器包括多个声源部分(70)和衍射板(90)。 多个声源部分输出声音。 改变来自第二声源部分(75)的声音的输出方向性,从而与衍射板中的从第一声源部分(71)输出的声音相干扰。 衍射板通过面对第二声源部分的声音输出侧而布置。 第一声​​源部分和第二声源部分被布置成具有不同的声音输出方向性。
