BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of the present invention, and FIG.
2 is a longitudinal sectional view of the present invention. 1 is cone paper, 2 is a perforated plate,
3 is a coil, 4 is a magnet, and 5 is a mounting hole.
DETAILED DESCRIPTION OF THE INVENTION The invention relates to a loudspeaker fitted with a
perforated plate (2). The conventional speaker could not cancel the divided vibration of the cone
paper. As a result, harmonics of human power are generated, and even if there is no input, corn
paper continues to shoot. This is a noise and badness of the hills, and it was a hopeless thing with
the child 1, the $ HiFi speaker. The present invention relates to a speaker capable of improving
the above-mentioned drawbacks and capable of reproducing a deep bass with a small aperture.
The structure is one in which a holed temporary (2) is attached to the front of a conventional
speaker. Σ) Principle ′ ′ is that there is no air column in the hole made of perforated plate i2)
and the space made by cone paper ill, and the cone paper front gear caused by division and
vibration of cone paper) pressure fluctuation is The pressure fluctuation is transmitted from the
belly to the node by the perforated plate t21, and the fluctuation is transmitted to cancel the
divided vibration. Since the cone paper tl + and the perforated plate (2) are bonded, the heavy
bass current, the low frequency signal current enters the speaker, the coil (3) vibrates, and the
cone paper When it is transmitted to f1 +, if it is the conventional speaker, the cone paper +11
and the sound which is not output at 17 is because the cone paper + l + adheres to the perforated
plate (2) so the cone paper +11 There is no need to play 7 ', the bass is played. Due to such a
principle, the poor sound and noise caused by the divided vibration are eliminated, and the deep
bass 1 is reproduced.
