Housing sound insulation structure of the electronic equipment

摘要

An object of the present invention is capable of wiring a simple component configuration and easy task, yet the speaker ringing sound sound insulation is not impaired of noise barriers is to provide a sound insulation structure to prevent the leak from the speaker storage compartment. The invention relates to a sound insulation structure inside the housing in an electronic device having a speaker, a circuit for storing the speaker storage chamber and an electric circuit for storing the speaker by case 2 and lower case 3 over to constitute a housing of an electronic device Configure the storage chamber, the upper case or the lower case or the upper case to form a parallel plate 20 is not formed parallel plate having a gap for accommodating a connection cord for connecting the speaker and the electrical circuit to a predetermined portion of the lower case to form a parallel plate housing portion 33 parallel to plate and the opposite site of forming the one or more ribs to prevent leakage of the speaker ringing sound from the speaker storage compartment on the inner surface of the parallel plate. .BACKGROUND 4
