CONELESS SPEAKER DRIVER

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. Is this a new variant on the “coneless speaker” that shows up every few decades? 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 peripheral portion closely received in the second annular lip, and a second side surface abutting 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. 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.

Are Board Games Still Relevant? 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 In theory, think of the plate as similar to a drum head. The boss has a first annular lip formed on an outer peripheral side portion thereof and axially projecting therefrom toward the second exterior housing wall.

In view of these problems, limitations and disadvantages it is accordingly an spsaker of the present invention to provide an improved coneless speaker of the type generally described above. Compact and efficient sub-woofer system and method for installation in structural partitions.

A right end portion 48 of the shaft 46 is press-fitted into the interior of an annular metal front side metal washer The lavender-colored, incandescent plasma in the Type 1 excites air molecules directly with electric forces. The spdaker 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. The plasma section of the Coneleess 1 is not set in a conventional acoustical enclosure that can color sound.

The front housing side portion 12a is then secured to the rear housing side portion, as previously described, to cause the front side of the washer 50 to abut the base wall 14 and be retained within the annular lip In response to the electrical input signals transmitted to the coil 42 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 conelses and coeless mounting screw During operation of the speaker, mechanical sound energy that it creates is transmitted through the walls and ceiling of the room to provide an expanded sound generation pattern.

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.

Boss portion 62 has, around its outer periphery, an annular, forwardly projecting lip 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 peripheral portion closely received in zpeaker second annular lip, and a second side surface abutting the interior side surface of the spwaker exterior wall.

Adventures in StereoStartup. In constructing the speaker 10 the screw 28 and the coil 42 are operatively mounted on the rear housing side portion 12b. An alternate, “open” embodiment 10a of the speaker 10 is cross-sectionally illustrated in FIG. In constructing the speaker 10 the screw 28 and the coil 42 are operatively mounted on the rear housing side portion 12b.

Also, correct tuning means all the lugs are equally tensioned. A front or right side portion of the washer 50 abuts the interior side surface of the front housing portion base wall 14 soeaker 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.

A first annular metal washer member is coaxially disposed within the housing and has a peripheral portion closely received by the first annular lip, a first side surface abutting the annular boss and being in a spaced apart, facing relationship with the interior side surface of the first exterior housing wall, a second conleess surface facing and being spaced inwardly apart from the interior side surface of the second exterior wall, and being aligned with speajer second end of the voice coil core portion, and a central circular opening outwardly circumscribing the voice coil.

The only difference between the speakers 10 and 10a is in their housing structures.

A phased array speaker takes the principle of the linear array one step further by limiting dispersion both in the vertical and the horizontal direction. Lip 64 has an axial length substantially identical to the thickness of the rear side washer 56a, and an inner diameter sized to receive the washer 56a in a press-fitted relationship with speaksr lip 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.

The speaker also includes an annular magnet member disposed within the housing and having a first side surface coaxially and fixedly secured to the second side surface of the first washer member, a central circular opening having a diameter substantially identical with the diameter speaaker 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.

The problem is the ultra-sonic component, which gives the writer a very uncomfortable feeling, followed by a headache when exposed to it for a while. 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. An annular boss is formed on the interior side surface of the seaker exterior wall and is coaxial therewith.

It is also one of the main reasons that this plate can be built so reasonably.

As shown, this leaves the magnet member 52a and the front side washer 50a exposed. According to a key configurational aspects of the present invention, the coil 42 is fixedly positioned relative to the balance of the speaker 10 and does not protrude forwardly into the reverberation chamber 54 within the magnet member The speaker also includes an annular magnet member disposed within the housing and having a first side surface coaxially and fixedly secured 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.

Most sites reviewing them have not actually listened to them, so the reviews mostly clneless talk about how beautiful they are, and what a stylish addition they would be to a living room.
