TOA Microphone in BD:

Microphone price in Bangladesh, A microphone, colloquially named mic or mike, is a device – a transducer – that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, radio and television broadcasting, and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic sensors or knock sensors. Toa Microphone price bd, Wireless Microphone price in Bangladesh

Several types of microphone are in use, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the piezoelectric microphone, which uses a crystal of piezoelectric material. Microphones typically need to be connected to a pre amplifier before the signal can be recorded or reproduced. Microphone price bd, Toa Wireless Microphone price in Bangladesh.

Latest Update TOA Wireless Microphone Price in Bangladesh 2021:

TOA Sound System in Bangladesh:

Improved product quality:

Phenol’s susceptibility to humidity makes it vulnerable to post-fabrication deformation of the dome shape, a flaw which can lead to friction between voice coil and magnet and eventual diaphragm damage. For this reason, we switched to polyimide that is more resistant to moisture than phenol.

Improved productivity:

While phenol-impregnated Conex requires about a month of curing time before the diaphragm becomes usable, this process is unnecessary with polyimide, and the finished product is ready for actual use just two minutes after formation. The adoption of polyimide therefore greatly improved productivity.

Improved low frequency characteristics:

Polyimide is made of softer materials than phenol-impregnated Conex. Generally, the more pliable the diaphragm material, the more suited it is to generating sounds in the lower frequency ranges. Therefore, our adoption of polyimide has allowed the production of sound offering a “thicker,” more “solid” impression than previously available in horn speakers.

Divided vibration and high frequency drop characteristics:

The poor high range characteristics of horn speaker driver units result from
the fact that the dome-type construction makes it more likely for divided
vibrations to occur. “Divided vibrations” refers to the various vibrations
occurring within the diaphragm when it does not vibrate in a uniform manner. When certain surfaces within the dome surface are vibrating in opposition to other surfaces on the diaphragm, the speaker will have difficulty sending out a clear sound.

This phenomenon occurs most conspicuously from a certain frequency up through the high ranges. The relative softness of polyimide materials renders them more vulnerable to such divided vibrations. Improving the high frequencies against this problem is a subject for efforts going forward.

Ring-type diaphragms are used in tweeters employed in large-scale sound reinforcement systems and in the pure audio field. TOA has been attempting to use these in full-range (wide reproduction frequency band) applications.

Improved high frequency characteristics:

Since ring-type diaphragms have a more symmetrical construction than
dome-type ones, divided vibrations are less likely to occur, and therefore they are a good candidate for extending reproducible frequency toward the high ranges.

The diagram shows the differences in vibration between dome and ring diaphragms, low frequency vibration on the left, high frequency vibration on
the right. Here we see reverse vibrations (red) occurring in the dome diaphragm at the higher frequency, whereas the ring diaphragm is relatively free of these and provides almost uniform vibration.

The Evolution of TOA’s Horn Speaker Driver Unit:

TOA has been manufacturing horn speakers practically from the
company’s very beginning, over eighty years ago in 1934, and today
we are recognized even among our longstanding industry
contemporaries as a veteran of highest expertise in this field. By
1949 we had succeeded in developing Japan’s first reflex-type horn
speaker. We have always dedicated ourselves to being “an
international company contributing to human society through sound
and communication,” valuing above all the physical craftsmanship
that allows the delivery of the clearest possible sound information to
listeners. In 1962, an inquiry from abroad led us to conduct
transmission testing on an ultra-large PA system. This system, which
used a 6.6-meter horn and a 4kW transistor amplifier, marked a
transmission distance of 12 kilometers. This achievement would
prove instrumental in laying out our destiny of long-running
involvement in outdoor public address systems.

TOA-developed horn speakers were often painted blue, and they
would become widely familiar as “blue trumpets” unique to TOA. In
Indonesia, where we established both factory and sales facilities in
1976, TOA horn speakers became such a part of the public
landscape that they were often referred to as “Toas.” They are still a
conspicuous part of everyday life there, most notably for public
address among the country’s many mosques.

Even today, horn speakers represent one of the fundamental shapes of public address speakers, offering a simple PA system that remains more indispensable than ever in delivering public announcements. In Japan, too, where natural disasters are frequent, horn speakers are an essential component in the outdoor emergency notification systems used for broadcasting evacuation instructions and other vital information. Naturally, the demand for the clearest possible outdoor broadcasting sound is strong in this market.

In 2011, the Great Tohoku Earthquake caused a massive tsunami that devastated a great number of Japanese coastal towns and villages, taking the lives of many who were unable to escape in time. As this disaster unfolded, the sheer number of outdoor speakers calling out
evacuation instructions caused pronounced sound overlaps that made
their announcements difficult to hear. And in many cases, the speakers were
simply swept away by the rushing waters. Reflecting on these systemic
flaws, TOA has been developing longrange speakers capable of delivering
clear announcements with fewer speakers over longer distances, and
we have been testing these repeatedly in metropolitan environments to
continue deepening our expertise in outdoor sound broadcasting and
reinforcement.

Issues for TOA Horn Speakers in BD:

Improvement of Articulation:

Horn speakers are comprised of a driver unit and a horn, and thus
achieve highest efficiency through impedance matching with the air.
The sound pressure drops on both sides of the 1–2kHz range,
however, resulting in certain distinctive audio characteristics that
cannot be considered favorable in terms of creating good-quality
sound.

Improving these high and low range frequency characteristics is one
of the issues key to improving horn speaker sound quality.
Particularly, we now understand that improving the high range
contributes greatly to improving the articulation of outdoor
broadcasts. Attenuation in the air is more conspicuous for the high
frequency ranges.

Improvement of Durability:

Out in the field, there is also an inherent need to have horn speakers deliver higher volume and send the sound farther. Often, however, attempts to meet this need through excessive power input cause malfunction by damaging or even destroying the speaker’s driver unit. Therefore, in addition to improving frequency characteristics, improving driver unit durability is also an issue requiring better solutions.

Additionally, the events of recent y e a r s h a v e b r o u g h t u s t o understand that in the disaster prevention market, improving frequency characteristics not only improves articulation, it also has a positive impact on long-distance sound transmission capability

The Process Leading to the TU-652M:

TOA horn speaker driver units can be divided into several generations based on their diaphragm materials and constructions. In the past, we used
dome-type diaphragms made of phenol-impregnated Conex. In 2004, we switched the material to polyimide, and in our most recent TU-660 we have
also changed the diaphragm construction from dome-type to ring-type. Each of these various changes have aimed to improve sound quality
(frequency characteristics), product quality, durability, and productivity. The details of this development process are explained below.
