SOUND GENERATOR INCLUDING A PARTITION FOR EFFICIENTLY SEPARATING THE FIRST BACK CHAMBER OF A SPEAKER AND THE SECOND BACK CHAMBER OF A RECEIVER

摘要

PURPOSE: A sound generator is provided to enable a back chamber of a telephone receiver to pass through a ring-shaped space surrounding the chamber, while making a back chamber of a speaker pass through an inner space of a case located on the outer side of the ring-shaped space, thereby substantially increasing the capacity of the back chamber of the telephone receiver. CONSTITUTION: A case(50) is used for an information apparatus. A frame(31) is installed in the case(50). A speaker has the first partition plate(36) while a telephone receiver has the second partition plate(41) in the frame(31). The first back chamber(43a) is located behind the first partition plate(36) of the speaker while the second back chamber(43b) is located behind the second partition plate(41) of the telephone receiver. A partition(31f) is integratedly formed in the frame(31) to separate the first back chamber(43a) from the second back chamber(43b).
