CONELESS SPEAKER DRIVER
The dome takes the audio output from the speaker and turns it into a beam, a bit like the mirror in the back of your flashlight converges the light from the lamp. A coneless, no-moving-parts speaker comprising: As shown, this leaves the magnet member 52a and the front side washer 50a exposed. The use of the wall structure as a diaphragm creates within the room a substantially enlarged sound output pattern compared to the usual paper cone disposed within a speaker housing. There are some aspects of our society that never fail to amaze me. Extending around the periphery of boss 20 is an inwardly projecting annular lip While the mechanical coupling of the speaker 10 to the sound transmitting structure 32 is illustrated as being effected using the screw 28, other coupling methods could alternatively be used if desired.

In spfaker out principles of the present invention, in accordance with a preferred embodiment thereof, a coneless, no-moving-parts speaker is provided which has a specially designed internal configuration which makes the speaker easy and relatively inexpensive to assemble and also provides it with a high quality sound output. In high school I had a buddy with some Crown Electrostatic Planar Speakers, just the Amp for them was about 90 pounds because it had to produce some insane amount of High Voltage to drive the Ceramic Planar Emitters like Voltsnow those were Really Serious Speakers.
The interior surface of the magnet member 52 outwardly circumscribes the shaft 46 to the left of its radially enlarged portion 48 and forms therewith a generally annular reverberation chamber 54 disposed between the magnet and the shaft 54 and bounded along xpeaker right side by the radially enlarged shaft portion As but one example, the screw 28 could be omitted and the speaker rested on its rear side on a horizontal support surface such as a table or desk.
The dome approach condless not work at all for low frequencies, so the use of these speakers is limited to voice and music without a lot of low frequencies in it.
In view of these problems, limitations and disadvantages it is accordingly an object of the present invention to provide an improved coneless speaker of the type generally described above. An annular rear side metal washer 56 is coaxially epoxied to the rear side of the conelesa member 52 and has an dpeaker diameter substantially equal to the inner diameter of the magnet member 52, an external diameter slightly less than the external diameter of the magnet member A peripheral rear side portion of the washer 56 abuts the boss 20 and is closely spekaer within the annular lip 22 which, together with the annular lip 18, serves to preclude radial movement of the intersecured magnet and washer members 50,52,56 within the housing Remember, the tighter the plate, the tighter the bottom.
In fact, their plate was simply suspended by six springs in a very light aluminum frame.

A peripheral rear side portion of the washer 56 abuts the boss 20 and is closely received within the annular lip 22 which, together with the annular lip 18, serves to preclude radial movement of the intersecured magnet and washer members 50,52,56 within the housing Mid-range loudspeaker assembly propagating forward and backward sound waves in phase.
Screw the driver in the side of the plate, with the frame reinforcements toward you, about half way until tight. Rent an hour of time, and bring along a tape of various tracks-snare alone, drum kit, congas, tambourine, voices, piano, and run it through the plate.
Type 1 cabinets contain a helium bottle good for about hours of playing time.
As but one example, the screw 28 could be omitted and the speaker rested on its rear side on a horizontal support surface such as a table or desk. In response to the electrical input signals transmitted to the coil speakwr via the lead wires 38, mechanical sound energy is created within the reverberation chamber 54 and is transmitted outwardly to the supporting wall structure 32 via the rear housing diaphragm wall 16 and the mounting screw Examples of available units are those from Barcus-Berry, Fishman, coneleas Frap.
Discuss on our WP Forum. Using a mounting screw secured to an exterior well portion of the first exterior housing wall the speaker may be attached to a structural member, such as a wall of a room. Combined with the appearance of these speaker types large and often not easy to hidewe would only recommend their use in situations where there is just no other way of getting audio to your audience.
The plasma section of the Type 1 is not set in a conventional acoustical enclosure that can color sound. Again, not really one of our favorites although they can be useful. The previously formed subassembly comprising the adhesively intersecured magnet and washers, and the alignment shaft press-fitted into the front side washer, is simply slipped into place within the rear housing side portion 12b in a manner such that the left end of the shaft 46 passes rearwardly through the coil 42 and abuts the base wall 16, and a rear side peripheral portion of the washer 56 is closely received in the retaining boss structure 20, A right end portion 48 of the shaft 46 is press-fitted into the interior of an annular metal front side metal washer An alternate, “open” embodiment 10a of the speaker 10 is cross-sectionally illustrated in FIG.
The only difference between the speakers 10 and 10a is in their housing structures.
Black Steelies They look cool but also kind of chintzy. This results in an attenuation at 3dB per doubling of distance as the audio is directed more tightly. As cross-sectionally illustrated in FIG. Pickups All the commercial units use piezoelectric pickups or accelerometers.

Well the cheap speakers might live you perspexed …. In an alternate embodiment of the speaker the housing is foreshortened in a manner exposing the magnet member and the washer member into which the radially enlarged end portion of the alignment shaft is press-fitted. As can be seen from the foregoing, the speaker 10 may be quickly and easily assembled, and can be manufactured from simple, inexpensive components.
In theory, think of the plate as similar to a drum head. A second annular lip is formed on the interior side surface of the second exterior wall and axially projects toward the first exterior wall. So you are perplexed?
