LOUGHREN Before taking up the actual design details of a which may be adapted from a standard phone unit. It Is instructive to study the several types tf loud speakers which are on the market. These fall, naturally, Into three classes: (a) The magnetic diaphragm type. (b) The moving coil type. (c) The Baldwin type. The magnetic diaphragm type Is of very common occurrence. It is essentially similar to the ordinary head phone, having a permanent magnet whose poles are placed close to the A magnet coll carrying diaphragm. many turns of fine wire Is mounted on each pole of the permanent magnet When no current Is passing through the colls the Iron diaphragm is, nevertheless, attracted by the permanent magnet If a direct current Is sent through the coils In the direction which strengthens the permanent magnet the diaphragm Is pulled down more, and with current in the opposite direction It Is pulled less strongly and springs up a little bit. Thus, with an alternating current, which flows first in one direction, then in other, the diaphragm Is pulled down, then partially released, and In this way sound waves are produced. This construction, properly handled, will lead to a very satisfactory loud speaker. But it has Its drawbacks for the constructor, as he must secure a perfectly smooth iron diaphragm of a larger diameter than usual. Also It Is essential that the diaphragm be mounted in the proper relation to the poles of the magnet. The Moving Coil Type. The moving coll type Is represented by the Magnavox Instruments. Here a small coll, very light In construction, Is fastened to the diaphragm. This coil Is suspended In the magnetic field of a strong electro-magnThe magnet consists of a large number of turns of wire on an Iron core. A small current, usually somewhere near 0.5 ampere, Is drawn from the A battery of the receiving set to excite this magnet. Now, when an al- loud-speake- r, Showing Fundamental Construction Baldwin Type. of current flows through the suspended coil the effect of the magnetic field Is to make the coll move up and down, thus causing the diaphragm to vibrate as In the other type. So far as I know, there Is no head phone on the market of this type. What I have called the Baldwin type is a loud speaker using a Baldwin phone, or an adaptation of it?. Figure 1 shows the fundamental construction of this instrument In the actual commercial product certain changes are made for compactness which are not shown because of difficulty of reproduction. In the figure M Is the permanent magnet, with north and south poles at N and S, respectively. P, p are the two pole pieces, between which the armature A Is suspended. The armature is pivoted at its center. At its right end the lever L Is fastened, and It Is by this that the motion of the armature is communicated to the diaphragm D. At the other end of the armature a small spring T Is provided to maintain a slight tension on the diaphragm. The coil C Is wound large enough to leave the armature room to vibrate within It, yet small enough to fit Inside the pole pieces. The operation Is as follows: When a current flows in the coil C the armature is thereby magnetized, one end becoming a north pole, the other south. Now, each pole piece Is magnetized throughout by the permanent magnet, the upper being north, the lower south. And since like ivies repel, while unlike ones attract, the end of the armature which has become the north pole will tend to move up, while the other will at the same time try to move down. Thus, both will contribute to exert a force on the diaphragm and to move it in accordance with tlte current. Cause of Chattering.
