An voice coil connected with some diaphragm is set inside the magnetic area and also a current is conducted via the voice-coil rendering it induce the diaphragm to vibrate and create sound waves.

Most lively headphones require small power in order for this to do the job. For this reason, most headphones in the marketplace are lively headphones. All these are utilized by ordinary audio listeners, musicians and skilled studio replicas equally.

Experts of lively headphones are that they’re frequently offered and usually are more economical that orthodynamic and ones that are nimble. Since modest power is necessary to induce them, the majority of these will utilize mobile computers and devices with out needing the headphone amp. A headphone plug in is really a miniaturized strength amplifier created specifically to induce the very small speakers in the headphones.

The drawbacks are the orthodynamic and electrostatic headphones may defeat with respect to clarity and speed.

2) Orthodynamic / / Isodynamic Headphones

Orthodynamic headphones had been quite popular globally from the 1970s. They’re thought by some to be older tech however possess a resurrection today.

Orthodynamic headphones have bigger and flat memory coilsthat insure both the diaphragm. It follows that the recent is way better spread towards the diaphragm, which then produces sound waves. Larger voice amps me an larger diaphragms (even larger than electrostatic headphones) and which usually means that the more power is necessary to induce them.

Experts of Orthodynamic headphones really are which they offer exemplary reply and noise quality like that of a Electro static.

Electro static headphones have motorists, that don’t own a sound coil. The diaphragm is also as an alternative charged by power. The diaphragm is set inbetween two electrically charged metal plates (electrodes), that can be perforated. After the diaphragm vibrates, air is coerced through the perforated metallic plates making a solid wave.

Bluetooth headphones tend to be pricier than dynamic headphones, and also are relatively rare. As a result of two and diaphragm alloy platesthat can be required to be more charged by power, the headphones desire a significant total of power to operate a vehicle. The sum is really far that ordinary amps that operate lively and/or orthodynamic headphones simply wont minimize it. A particular headphone amplifier will become necessary which regularly necessitates electric capabilities within the variety of 100 to 1, 000 volts.

The lean diaphragm that’s just some micrometers thick makes it to make a frequency result, which extends well over the perceptible limit of around 20 kHz. To put it differently, larger precision and noise quality is generated.

Akg and also Stax create static headphones.

Experts of bluetooth headphones will be the noise quality and endurance which they’re famous for.

Downsides of electrostatic headphones really are that they have been high priced, need that the master to buy a exceptional amp to induce them plus so they lack bass. There’s deficiency of hammer / effect when compared with lively headphones.

Uribe ruled for massacre in La Gabarra

They tied us up like dogs: survivor

La Gabarra, North Santander. General rejection has received the incursion of the Farc in this region of the country, where 34 scrapes, people dedicated to scraping the coca leaf, were slaughtered.

One of the survivors of the macabre scene narrated as he and his companions were tied up and thrown their faces on the floor and then the killers unloaded their weapons on their bodies.

Although the first versions indicate that the guerrilla group was 30, one of the survivors said that at the site where they were sleeping only five arrived.

Survivor narrates

“Only a few were saved. They, the killers, gave the women and two men five minutes to escape and tell the story.”

Benedict says he prayed to blessed souls, while breathing the smell of blood running down the floor by soaking his head. Stacked among the bodies of his companions, playing dead, he was able to save himself.

He was hit by only one bullet that went under his armpit, from all the ones who spat out the weapons, in bursts, that wiped out the other 34 lives. And although he felt he died with the wails and entreaties of others, he preferred to stand still. All massacred, hands tied behind their backs, “tied up like a dog and thrown up facing the floor,” he said angrily.

Amid the chiaroscuro of the morning, Benito could only see about five or six young men in military uniform and modern weaponry who told him and his companions to be blind, deaf and mute if he wanted to live.

44 thousand hectares of illicit crops exist in the Catatumbo.

“Stand up and don’t go run because whoever runs we kill,” says the guerrillas said. Apparently the order was to kill them all. When it all happened, he had the strength and courage to ask the neighbors to come up and pick up other wounded. He soon picked up a canoe bound for a health center in La Gabarra.

Strong pronouncement of the President

Expressing his rejection of the massacre of 34 people in La Gabarra, Norte de Santander, for part of the Farc, the President of the Republic, Alvaro Uribe Vélez has just questioned the NGO Amnesty International (AI).

The Head of State Amnesty International has used his good name to accuse the public force and mistreat it without any basis. “There are international amnesty actions that resemble the actions of terrorists. For not denouncing AI, terrorists have been allowed to be legitimized,” the representative said during a police stop at the Escuela General Santander.

“Here, for saving appearances, in so many decades we have let terrorism mistreat Colombians, by keeping hypocritical rules of courtesy and not having the courage to denounce Amnesty International, we have allowed them to legitimize terrorism internationally,” Uribe Vélez said.

The Army deviated research

Bogotá. An operation allegedly orchestrated by the Army to conceal evidence to clarify the events that occurred in the municipality of Guaitarilla, Nariño, in which seven policemen and four civilians were killed, Senator Luis Elmer Arenas denounced.

In his intervention, the Senator assured that “the crime scene was altered by the military and that the Das and the military attempted to mount the investigation.”
The congressman made the revelations during a debate in the plenary of the Senate of the Republic, where the Minister of Defense, Jorge Humberto Uribe Echavarría, attended; the commander of the Military Forces, General Carlos Alberto Ospina; the commander of the Army, General Martín Orlando Carreño; The Deputy Attorney General of the Nation, Andrés Ramirez and the solicitor Edgardo Maya Villazón.

According to the facts reported by Arenas Parra, members of the Army attempted to deflect research into the facts to hide the real circumstances in which the confrontation occurred between a patrol of the Boyacá Battalion and a group of the Gaula de Pasto, on March 19.

The Police and Army reportedly acted on separate reports to the two forces, provided by members of a criminal organization known as the Tiritingos.
Arenas presented recordings with the testimonies of some of the survivors.

According to evidence compiled by Senator Arenas, including testimony from the survivors, some members of the criminal gang informed the military of the existence of a cocaine lab that was to be stolen by an armed rifle gang.”

The gaula agents and army patrol were found at the time of the Gaula and Army patrols. Officers identified the property and called for a ceasefire and were apparently topped. Later, there were other bursts to hit the vehicles, Senator Arenas said in the debate.

The bodies of the victims, revealed the congressman’s complaint, were stripped of their manned weapons, bulletproof vests and clothing. He also claimed that the bodies were moved and the weapons next to him did not match those they received at the time of their departure. “That they were shot, I have no doubt,” Arenas said of the fate of the fatal victims.


In his reply, Defense Minister Jorge Alberto Uribe stated that “I am not so irresponsible to make judgments that could interfere with the investigations of the Military Criminal Justice and the Office of the Attorney General,” and questioned the fact that the session released evidence as irrefutable facts. He added that his silence in front of the subject will be indefinite as long as he is unsure of what happened in Guaitarilla.

The Minister called Arenas’ presentation shocking but unacceptable.


Free Irish, but

Bogotá. Niall Connolly, James Monaghan and Martin McCauley, the three Irish members linked to the Irish Republican Army (IRA) and the Farc, were released on bail last Tuesday night. However, foreigners will not be able to leave the country until the Superior District Court resolves their acquittal that was appealed in the second instance. The Irish were acquitted by a judge last April, but decided not to leave prison because they did not have the security guarantees they requested from the government. The three foreigners were captured in August 2001, after arriving in the former de-escalation zone, after being appointed to train the Farc guerrillas in explosive handling and terrorist tactics. “We think it’s unfair that they have to stay in this country. They are in real difficulty and dangerous circumstances,” said the Irish’ defense.

One hundred years of conviction

Bogotá. The Specialized Third Criminal Judge of Villavicencio sentenced to a hundred years in prison three people found guilty of the extortive abduction of Lithuanian boy Vitys Karanauzcas Cioderis. The conviction was imposed against Mary Noralba Cano Pedraza, Blanca Yamile Vergara Jaimes and Rubiela Sánchez Useche for their involvement in the abduction of the minor. Cano Pedraza and Vergara Jaimes were each sentenced to 384 months in prison and a fine of 18 thousand 571 legal minimum monthly wages in force. Sánchez Useche was sentenced to 408 months in prison and a fine of 27,500 monthly legal minimum wages, the Attorney General’s Office reported. Vitys Karanauzcas, 3, was abducted in Villavicencio on April 1, 2003, while transporting on a school bus from his home to the school garden. On April 8, 2003, the GAULA de la Policía rescued the child in the Castilla de Bogotá neighborhood.

Medical stop at St. Jerome’s Hospital

Comes page 1A

Doctors also indicated that although they have always been willing to collaborate with the hospital, at this time they are in a situation of despair, since many of them depend exclusively on their work in the San Jerónimo, so at this stage they have been forced to exhaust their savings resources in order to fulfill their obligations.

On the other hand, the surgeon Ricardo Balcázar, assured that several of the Galenos have already started to lose some of their properties and in the case of young people who are just starting to work, have not been able to take off as professionals, so he called the situation a social problem.
The doctor also regretted having to resort as a pressure mechanism to be recognized for their work, to refuse to provide the services for which they prepared for so many years in a university, indicating that they have no choice.

For his part, the manager of the Hospital, Jesús Jiménez Isaza has always taken responsibility for the arrears with the medical bodies to the ARS and epS, entities to which he accuses of delaying the payment processes for services provided that they must make to the Saint Jerome.


The crisis in the hospital arises just as the second stage of the meritocracy process begins to choose the new Manager of the care center, because as it is known, since yesterday the registrations for those interested in occupying the position in place of Jesús Jiménez Isaza are open, who has repeatedly confirmed that he will register his resume because he is interested in continuing to the front of the hospital , considering that you have the merits to do so.
According to Jiménez Isaza, in what is going on in his period almost all the goals have been met but still a long way to go and he always likes to conclude what begins.
