Ωχ! :shock:

Έλεγα από μέσα μου κάτι για ξύλα...και περίμενα να δω καμμιά ξύλινη κουφαμάρα....

Αυτό έιναι από...άλλο πλανήτη! :shock:

Ναι, σαν αυγό του Alien :shock:

Άντε, με το καλό να πλησιάζουμε σιγά σιγά στο απόλυτο: τον ιονισμό του αέρα που μας περιβάλλει, ώστε να ακούμε και να βλέπουμε τον καλλιτέχνη της επιλογής μας σε φυσικό μέγεθος ("beam me up, Scotty"...//;-)

September 14th announcement

The nippon victor corporation on the 14th, has 12 face piece structures, it announced that the “breath sphere type speaker” was developed. From September 21st to 24 days with [pashihuiko] Yokohama it is held it is displayed with the same company booth “of A&V [huesuta] 2006”.
　Being natural, the speaker that it has the efficiency which is close to “the ideal sound source” because it actualizes ideal sound field playback. We to do globose 12 face piece structures are adopted, the whole as a diaphragm function. In order to breathe quite, you say that it vibrates, generates sound.

The usual speaker vibrates the circular diaphragm as a sound source, discharges the sound wave. Because the direction which it discharges has been decided besides the fact that directivity is born, in order to load unit onto the enclosure, the disorder of the frequency characteristic with the form of the enclosure occurs. There is also the influence and the like where the sound wave diffracts in the cabinet, those such as that form the specific sound quality.

　But, in order to do the playback which is faithful to field sound, it is necessary to lose such topic. At Victor, “breath sphere” to decide the sound source of ideal, 'sphere type speaker “GB-1” after of 67 years, seeking the ideal sound source, it continued research then.

　Way breath sphere true to its name, you breathe, expansion/it is the sphere which reduces. In order to breathe with the image like the balloon, sound is given out by the fact that it vibrates. Because you can call the whole the diaphragm, the same wave front to all directions can be spread, because is not the disorder in radiation impedance, there is no cabinet there is no either diffraction. When getting near to the flat condition sound source, it has the advantage such that there is no disorder of the near sound field which occurs.

　When this breath sphere it can actualize, as the speaker the speaker exists in electric acoustic route and can create the circumstance the Nakano way. Because of that, because there is no character of the speaker and it is faithful to field sound, there is no either directivity, being wherever of the rooms, you say that real it can enjoy the sound field, you say that it becomes the ideal speaker.

As for the experimental model which this time Victor developed, those which aim toward this breath sphere type speaker. It differs from complete globose, but diameter 10cm suitable sphere it connected 11 diaphragms of 5 rectangularities and it consisted by the fact that it adjusts, it is designed to be 12 face piece structures. Vibrating edition of each surface the driver has driven with dynamic system, 11 drivers which exclude the base are built in.

　Largest feature is not to install the diaphragm in the framework of 12 face pieces, has connected 11 diaphragms in just the edge. Because of that, the speaker surface which excludes the edge has become all diaphragms and the emission aspect, be able to remove the influence of the frame and the cabinet, you say that clearing which does not have the strain impression it can do playback.

　While in order to support the diaphragm, with high elasticity, suspension of the new development that arrangement to 2 crossing it removed specific resonance. You say that the diaphragm can be driven in order to breathe, accurately.

The graph which shows the influence which the cabinet causes to frequency characteristic. But globose smooth, because the cabinet does not exist in the breath sphere speaker, you say that it becomes more ideal frequency characteristic than this graph,

Connecting the diaphragm and the diaphragm in only the edge. Like the cover the whole it has been overturned

As for material of diaphragm high rigid fiber-reinforced plastic. You say that by the fact that the division vibration is held down, clear normal position wide playback frequency zone was actualized

However, in complete case where it is globose directional characteristics become non-directionality, but the diaphragm of 12 face pieces because of plane surface does not become non-directionality, that way becomes distorted directional characteristics. Then, in sound emission direction like the mountain adopting the diaphragm of the pentagon which has the form which protrudes outside. You say that, the non-directionality where sound spreads uniformly was actualized. In addition, in order to designate the frequency characteristic of the diaphragm whose form is complicated as flat, applying individual [oburikon] technology, it developed it has become the “Weibull curved diaphragm”.

　Furthermore, in order in the experimental model to supply silent playback ability, it has combined with the woofer which directs unit on. As for crossover frequency 250Hz. With demonstration from the CD player of the source it input into the AV amplifier, the amplifier (AX-M9000) transferred frequency separately with DSP inside, the bi- amplifier drove the respective speaker.

Diameter 10cm suitable sphere it connects 11 diaphragms of 5 rectangularities and it consists by the fact that it adjusts

With computer analysis you deduced in the diaphragm the “Weibull curve” is given

Low it has combined with the woofer in order to supply the limits. You set unit to up, have made non-directionality

As for playback sound very with clearing, uniformity and the sound field which quite spreads naturally is a special feature. Because of non-directionality, with the usual source as for the acoustic image it does not go with pinpoint, but the excellent normal position impression also height being felt is impressive. Especially, [raivu] with the music which is recorded, 2ch playback when with the extent of the sound field which cannot be thought, the eye is closed the speaker goes out, can taste the kind of feeling which comes to the place where it is not the audition room. In addition, faces in the audition, changing the position of the head, it probably can call side feature only of the spherical speaker that the sound field and the acoustic image do not change.

You aim toward commercialization, examine also the color variation
