The mark consists of a three-dimensional configuration of a speaker. The body of the speaker is generally cylindrical with rounded top and bottom edges. The surface of the speaker features two bands of elongated, rounded rectangular perforations arranged in a staggered, brick-like pattern. One band is located around the top portion and another, wider band is located around the middle portion of the speaker. The central section of the speaker between the perforated bands appears as a smooth, solid surface without any perforations. The bottom portion of the speaker is also solid and smooth.
