PURPOSE:To obtain a speaker capable of emitting the natural sound of high Q by providing a partition plate at the sound generating part sides of plural resonance pipes attached to the sound generating part of the speaker. CONSTITUTION:A diaphragm vibrates in the sound generating part 37 so as to generate a prescribed sound wave, and the generated sound wave is emitted to an external part through the insides of plural tubular bodies 41, 43, 45. In this case, the tubular bodies of some number resonate specially, and said resonant sounds and the rest of the sounds having passed through other tubular bodies are mixed with each other, and the beautiful sound of a complicated waveform is generated. Because the partition plates 51, 53, 55 are provided between the tubular bodies 41, 43, 45 and the sound generating part 37, the length of an air column for determining a resonance frequency comes clear, and the speaker comes to be the one with the large Q as a whole, and the natural sound is obtained, and the speaker suitable to be used as the sound source of a musical instrument can be obtained. |
