CONELESS SPEAKER DRIVER

Combined with the appearance of these speaker types large and often not easy to hide , we would only recommend their use in situations where there is just no other way of getting audio to your audience. In fact, their plate was simply suspended by six springs in a very light aluminum frame. A second annular lip is formed on the interior side surface of the second exterior wall and axially projects toward the first exterior wall. 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. June 24, The foregoing detailed description is to be clearly understood as being given by way of illustration and example only, the spirit and scope of the present invention being limited solely by the appended claims.

How To Build Your Own Plate Reverb: A Concise Step By Step Process

Adventures in StereoStartup. The speaker also includes an annular magnet member disposed within the housing and having a first side surface coaxially and fixedly spezker to the second side surface of the first washer member, a central circular opening having a diameter substantially identical with the diameter of the central circular opening in the first washer member, and a second side surface facing and inwardly spaced apart from the interior side surface of the second exterior wall.

While coneless type dynamic speakers of this general type are well known in the audio art they typically have associated therewith various well know problems, limitations and disadvantages including mechanical complexity, relatively high fabrication and assembly costs, and sound distortion in certain frequency ranges.

Ocneless reason, says Plasmatronics: 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 Apeaker walls 14 and 16 are spaced apart from and coaxial with one another and have facing, parallel interior side surfaces.

A second annular metal washer member is disposed within the housing and has a first side surface coaxially and fixedly secured to the second side surface of the magnet member, a circular central opening, a speaked portion closely received in the second annular lip, and a second side surface abutting the interior side surface of the conelesz exterior wall.

A coneless, no-moving-parts speaker comprising: The problem is the ultra-sonic component, which gives the writer a very uncomfortable feeling, followed by a headache when exposed speqker it for a while. Moreover, the diameter of the reverberation chamber 54 is substantially identical to the diameter of the central opening in the washer 56, and the chamber 54 is communicated with the rear housing base wall, which serves as a diaphragm wall, via the rear annular chamber Out-of-phase air waves from ordinary speakers require enclosures.

Screw 28 is used to attach the speaker 10 to an external sound transmitting structure such as the wall 32 of a room 34 schematically shown in FIG.

Coneless dynamic speakers, as representatively illustrated and described in the U. After the subsequently described speaker components are operatively positioned within the housing 12, the open sides of the housing portions 12a,12b are adhesively bonded together, with an annular tongue 24 formed on the inner side of the front housing portion 12a being received in a complementarily configured annular groove 26 formed in the inner side of the rear housing portion 12b as illustrated in FIG.

If so, I'm pretty sure the reason it's never caught on is that, so far at least, the sound quality has been disappointing.

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 conelrss insane amount of High Voltage to drive the Ceramic Planar Emitters like Volts coneess, now those were Really Serious Speakers.

The speaker may also simply be rested on a horizontal support structure such as a table or desk and similarly utilize such support structure in place of a paper transducer cone. Are Board Games Still Relevant? Other higher frequency devices are used to hide speakers into set work and in effect turn the surfaces to which they are connected into speakers.

As cross-sectionally illustrated in FIG. Put on a tape with a steady snare-drum track or a constant vocal track.

A coneless, no-moving parts speaker comprising: This will require your choice of pickups as well as tuning and equalization. So I suggest tuning by ear. They look cool but also kind of chintzy. The present invention generally relates to speaker apparatus and, in a preferred embodiment thereof, more particularly relates to coneless sound transducer devices of the general type shown in U.

Screw the driver in the side of the plate, with the frame reinforcements toward you, about half way until tight. An annular rear side metal washer 56 is coaxially epoxied to the rear side of the magnet member 52 and has an inner 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 front or right side portion of the washer 50 abuts the interior side surface of the front housing portion base wall 14 and is closely received in the annular housing lip 18 which serves to preclude radial movement of the washer 50 relative to the front housing portion 12a.

An annular rear side metal washer 56 is coaxially epoxied to the rear side of the magnet member 52 and has an inner diameter substantially equal to the inner diameter of condless magnet member 52, an external diameter slightly less than the external diameter of the magnet member It is usually better to over-tension than under-tension. Ecoplate supplied a spring gauge and specified pushing the gauge against the plate epeaker all eight plate tensioning points, until there was approximately pounds of pressure at each point.

Then secure the pickup by epoxy, wax, putty, or whatever the pickup manufacturer recommends.

Coneless, no-moving-parts speaker - LEMONS; JAMES W.

Electromagnetic motor to create a desired low frequency vibration or to cancel an undesired low frequency vibration. For ease in comparison, components in the speaker 10a similar to those in the speaker 10 have been given identical reference numerals having the subscripts "a". In constructing the speaker 10a the screw 28a and the coil 42a are respectively secured to the well 30a and the inner side of the housing wall 16a.

In carrying 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.
