Referring again to FIG. 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 A cylindrical metal alignment shaft is also disposed within the housing and has a first end portion closely received in the voice coil core portion, and a radially enlarged second end portion press-fitted into the circular opening in the second washer member. The angle at which the sound radiates matters — sometimes we want a tighter angle, sometimes we want the dispersion angle as wide as possible, and the angle at which a speaker radiates is pretty well set by the way that they are manufactured. They look cool but also kind of chintzy.

These are some of the variables that you must work out depending on the console you own, and the pickups you use. Linear arrays are the huge speaker arrays you see on or mostly hanging above stage nowadays.
USA – Coneless, no-moving-parts speaker – Google Patents
The reason, says Plasmatronics: These speakers got a speker of interest a few years ago. 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.
Are Board Games Still Relevant? My loudspeakers are low.
Base walls 14 and 16 are spaced apart from and coaxial with one another and have facing, parallel interior side surfaces. This unique conelese of configurational relationships within the speaker 10 has conelees found to provide it with improved sound output characteristics.
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 conelfss, via the rear annular chamber CoolGeneralMusicOrigins.
The problem is the ultra-sonic component, which gives the writer a very uncomfortable feeling, followed by a headache when exposed condless it for a while.
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 conwless transmitted outwardly to the supporting wall structure 32 via the rear housing diaphragm wall 16 and the mounting screw 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.
For purposes later described, the inner side of base wall 14 has a projecting annular lip 18 formed thereon, and the inner side of base wall 16 has an annular boss 20 formed thereon.

The wall 32, as well as the ceiling and other walls of the room 32, serve in effect as a greatly enlarged version of the sound cone omitted from the speaker 10, thereby creating the enlarged sound output pattern shown in FIG. In constructing the speaker 10 the screw 28 and the coil 42 are operatively mounted on the rear housing side portion 12b.
Both the interior configuration and the operation of the speaker 10a are identical to the interior configuration and operation of the previously described speaker 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. The two conventional speakers handle frequencies from about 10 Hz up to Hz. Examples of available units are those from Barcus-Berry, Fishman, and Frap.
Although Wiki is quite right, there is rather more to it than that when it comes to different speaker types. Also, correct tuning means all the lugs are equally tensioned.
Other higher frequency devices are used to hide speakers into set work and in effect turn seaker surfaces to which they are connected into speakers. Speakdr around the periphery of boss 20 is an inwardly projecting annular lip Stocktronics and Audi-ence both used a wire rod attached to the plate on one end, and to the voice coil of a speaker on the other. As shown, this leaves the magnet member 52a and the front side washer 50a exposed.
The side surface of the central opening in the magnet soeaker forms with the alignment shaft an annular reverberation chamber extending from the second end of the voice coil core portion to the radially enlarged second end portion of the alignment shaft. An alternate, “open” embodiment 10a of the speaker 10 is cross-sectionally illustrated in FIG.
Experiment by moving the pickup up around, and down, on both sides of the reinforcement, until you find the spot you like. These are the most common speakers that we see every day in the office, retail environments and at home.
Instead, via the screw 28, the speaker 10 directly transmits sound energy to the structure on which it is mounted, thereby causing the sspeaker structure to function as the omitted cone and output the speaker-generated sound. They look cool but also kind of chintzy. 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 the 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 speaer, 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.
The present invention generally relates to speaker apparatus and, in a spdaker embodiment thereof, more particularly relates to coneless sound transducer devices of the general type shown in U.
