A phone telephone plugalso known as phone jackaudio jackheadphone jack or jack plugis a family of electrical connectors typically used for analog audio signals. The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used. The phone connector is cylindrical in shape, with a grooved tip to retain it, telephone plug. In its original audio configuration, it typically has two, three, four telephone plug, occasionally, five contacts.

Three-contact versions are known as TRS connectorswhere T stands for "tip"R stands for "ring" and S stands for "sleeve", telephone plug. Ring contacts are typically the same diameter as the sleeve, the long shank.

The outside diameter of the "sleeve" conductor is 6. The "mini" connector has a diameter of 3. Specific models, and connectors used in specific applications, may be termed e. The 3. In the Telephone plug, the terms jack plug and jack socket are commonly used for the respective male and female phone connectors.

Phone plugs and jacks are not to be confused with the similar terms phono plug and phono jack or in telephone plug UK, phono socket which refer to RCA connectors common in consumer hi-fi and audiovisual equipment. Modern phone connectors are available in three standard sizes. In FebruaryC. Scribner was issued US Patenttelephone plug, [14] for a "jack-knife" connector that is the origin of calling the receptacle a "jack". Patents , [16] , [17] andrelating to an improved design that more closely resembles the modern plug.

Clausen received a patent on an improved design. Western Electric was the manufacturing arm of the Bell System telephone plug, and thus originated or refined most of the engineering designs, including the telephone jacks and plugs which were later adopted by other industries, including the U, telephone plug.

ByWestern Electric had designed a number of models for different purposes, including: [20]. It became very popular with its application on the Walkman inas unlike earlier transistor radios, these devices had no speaker of their own; the usual way to listen to them was to plug in headphones, telephone plug.

There is also an EIA standard for 0. The 2. They often appeared next to a 3. They were also used for low-voltage DC power input from wall adapters. In the latter role they were soon replaced by coaxial DC power connectors. Four-conductor versions of the 3. A four-conductor version is often used in compact camcorders and portable media players, providing stereo sound and composite analog video.

By the s, broadcast radio stations were using Western Electric Code No. The type plug was used instead of the standard type switchboard plug because the location of the large bulb shape on this TRS plug would have resulted in both audio signal connections being shorted together for a brief moment while the plug is being inserted and removed. The Type plug telephone plug this by having a shorter tip.

Professional audio and the telecommunication industry use a 0. In addition to a slightly smaller diameter, they have a slightly different geometry, telephone plug. Though unable to handle as much power, and less reliable than a 6. These connectors are still used today in telephone company central offices on "DSX" patch panels for DS1 circuits. A telephone plug type of 3. Plugging a stereo plug into one of the two mono jacks typically results in the audio coming into only one ear, telephone plug.

Adapters are available. A short-barrelled version of the phone plug was used for 20th century high-impedance mono headphones, and in particular those used in World War II aircraft. These have become rare. It is physically possible to use a normal plug in a short socket, but a short plug will neither lock into a normal socket nor complete the tip circuit.

Less commonly used sizes, both diameters and lengths, are also available from some manufacturers, and are used when it is desired to restrict telephone plug availability of matching connectors, such as 0.

US military phone connectors include both 0. Commercial and telephone plug aviation GA civil airplane headset plugs are similar, but not identical, telephone plug.

There is a confusingly similar four pole or four conductor British connector with a slightly smaller diameter and a different wiring configuration used for headsets in many UK Military aircraft and often also referred to as a NATO or 'UK NATO' connector. The original application for the 6. Of these many varieties, only the two-conductor version with a rounded tip profile was compatible between different manufacturers, and this was the design that was at first adopted for use with microphoneselectric guitars, telephone plug, headphonesloudspeakerstelephone plug, and many other items of audio equipment.

When a three-conductor version of the 6. This attempt has long been abandoned, and now the convention is that all plugs fit all sockets of the same size, regardless of whether they are balanced or unbalanced, telephone plug, mono or stereo.

Most 6. The profiles of stereo miniature and subminiature plugs have always been identical to the mono plugs of the same size, telephone plug. Because of a lack of standardization in the past regarding the dimensions length given to the ring conductor and the insulating portions on either side of it in 6.

This can result in a contact in the socket bridging shorting the ring and sleeve contacts on a phone connector. The most common arrangement remains to have the male plug on the cable and the telephone plug socket mounted in a piece of equipment: the original intention of the design. Personal computer sound cardssuch as Creative Labs ' Sound Blaster line, use a 3. Sometimes termed phantom powerthis is not a suitable power source for microphones designed for true phantom power and is better termed bias voltage.

Note that this is not a polarizing voltage for the condenser, as electrets by definition have an intrinsic voltage; it is power for a FET preamplifier built into the microphone. Compatibility between different manufacturers is unreliable. The Apple PlainTalk microphone jack used on some older Macintosh systems is designed to accept an extended telephone plug. If a PlainTalk-compatible microphone is not available, the jack can accept a line-level sound input, though it cannot accept a standard microphone without telephone plug preamp.

Normally, 3. Thus, for a sound card with 5. This is to accommodate telephone plug 6. Note that Creative's documentation uses the word "pole" instead of "conductor".

If a recorder provides plug-in power, and the microphone does not need it, everything will usually work ok, although the sound quality may be lower than expected, as the microphone may not work optimally with a constant DC current flowing through it.

In the converse case recorder provides no power; microphone needs powerno sound will be recorded. Neither misconfiguration will damage consumer hardware, but providing power when none is needed could destroy a broadcast-type microphone. Three-conductor 2. These are used both for handsfree headsets esp. Wireless connectorless headsets or headphones usually use the Bluetooth protocol.

The four conductors of a TRRS connector are assigned to different purposes by different manufacturers. Any 3. Mono audio will usually work, but stereo audio or microphone may not work, depending on wiring. Two different forms are frequently found, both of which place left audio on the tip and right audio on the first ring mirroring the configuration found on stereo connectors.

Where they differ is in the placement of the microphone and return contacts. The first, which places the ground return on the second ring and the microphone on the sleeve, is used by Apple 's iPhone line through the iPhone 6HTC devices, telephone plug SamsungNokiaand Sony phones, among others.

The second, which reverses these contacts, is used by older Nokia mobiles, older Samsung smartphones, and some Sony Ericsson phones. Some computers now include a TRRS headset socket, telephone plug, compatible with headsets intended for smartphones. MMICtelephone plug technical requirements and telephone plug methods for a 5-pole socket and plug configuration.

Therefore, P. TRRRS connectors enable following audio applications: active noise cancelling, binaural recording and others, where dual analogue microphone lines can be directly connected to a host device. Panel-mounting jacks are often provided with switch contacts. Most commonly, a mono jack is provided with one normally closed NC contact, which is connected to the tip live connection when no plug is in the socket, and disconnected when a plug is inserted.

Stereo sockets commonly provide telephone plug such NC contacts, one for the tip telephone plug channel live and one for the ring or collar right channel live. Some designs of jack also have such a connection on the sleeve.

As this contact is usually ground, telephone plug, it is not much use for signal switching, but could be used to indicate to electronic circuitry that the socket telephone plug in use. The original purpose of these contacts was for switching in telephone exchanges, for which there were many patterns. Two sets of change-over contacts, isolated from the connector contacts, were common. The more recent pattern of one NC contact for each signal path, internally attached to the connector contact, stems from their use as headphone jacks, telephone plug.
