Abstract

PURPOSE:To vibrate a voice coil with excellent linearity without rolling by forming a supporting member in a honey-comb construction in speaker which is installed through a supporting member on a frame so that it can vibrate. CONSTITUTION:An outer circumference of a megaphone-shaped diaphragm 2 is supported on a frame 1 by means of an edge 3. A voice coil 4 is fixed inside of the diaphragm 2, and a spider 5 supports the coil 4 on the frame 1. A vibrator 6 has a gap 6a corresponding to the coil 4, which is supported in the prescribed position in the gap 6a in the condition floated by the spider 5. It is formed in a honey comb construction and supports the voice coil 4 in four directions. Thus the coil 4 is vibrated with excellent linearity and without rolling, and the tone quality can be made satisfactory.

Figure 6 shows another example of a conventional speaker.
In the figure, (1) to (4), (6), and (6a) are the same as those of the above-mentioned example of the conventional speaker. No spider is used here and the voice coil (4) is supported by the edge (3). There are various types such as edge-nih roll, wavy, and tangential gather, but the roll edge shown in Fig. 4 is the most commonly used.

However, the conventional support devices called spider (5) and gap (3) are not completely linear in displacement due to vibration due to their structure, and are prone to rolling. In particular, the degree of nonlinearity increases near the end of the wave. Therefore, the voice coil (4) is in the gap (6a).
There was a drawback that the sound quality of the speaker was deteriorated due to contact with the vibrating device (6) inside the speaker.

When this fly cam structure is used as a support member, the voice coil (, +1 is υ, which is difficult to twist in the horizontal plane direction, so it is difficult to roll. Also, the point (91) moves with good linearity in both the x and y directions. For this reason, the voice coil (4
) can also be prevented from coming into contact with the vibration device (6) within the gap (6a).
