Description

FIELD OF TECHNOLOGY

The invention relates to an improvement in the structure of an audio plug, in particular to an audio plug receiving power or a signal from an audio jack without affecting the normal use of a speaker of an electronic product.

BACKGROUND

With the rapid development of computer and communications technology, electronic products have become even more popular; especially mobile phones have become one of the essential devices of modern people. At the same time, the industry continues to introduce new mobile phones with various features to enhance the convenience and practicality of mobile phones. For example, smart phones (smartphones) have become the main focus of the market and comprehensive applications have earned the love of consumers.

FIG. 1 shows traditional headphones and a 3.5 mm audio plug. An audio plug 10 is provided for insertion into the audio jack 12 of the mobile telephone 11 and has a basic signal transmission function. US Patent No. 7,912,501 B2 from Apple Inc., as shown in FIG. 1B, discloses an I / O audio headphone plug comprising a plug 400 having four signal-conducting regions separated by an insulating ring 405 and signal-conducting regions are numbered 1 to 4, wherein the signal-conducting regions 2 to 4 have an outer diameter of 3.5 mm Each signal conducting region has an assignment of transmitting various signals, as shown in FIG. 2. For example, for a non-stereo headset, the signal-conducting region 1 is used for one speaker and the signal-conducting regions 2 and 3 are for grounding (GND) and the signal-conducting region 4 is used for a microphone (Mic). Moreover, for another headset system, the signal-conducting region has the function of transmitting other signals. For example, for a stereo headset, signal-conducting regions 1 and 2 represent the left and right channels; for headphones, signal conductive areas 3 and 4 are intended for grounding. Thus, US Pat. No. 7,912,501 B2 disclosed mainly provides a plug and plug detection circuits.

However, the disclosed audio plug 10, 400 is a solid structure with several metal rods and three insulating rings 405 and its main function, as shown in FIG. 1B, is receiving signals by appropriately connecting signal-conducting areas 1 to 4 with first to fourth terminals (terminals) 121 ~ 124 at a predetermined position in audio jack 12. Thus, sounds including a call sound are transmitted through signal-conducting areas to external headsets or a microphone; therefore, no sounds will be output from the speaker 13. That is, when the audio plug 10 is inserted into the audio jack of the headphones, only the sound of an incoming call can be heard; after pressing the answer key, the audio signal is transmitted to the headphone jack 12, and not to the speaker 13. In addition, there is no interior space that can be used so that the audio jack 12 can only be used to receive the audio signal. Therefore, there is room for improvement.

ESSENCE OF A USEFUL MODEL

The primary objective of this utility model is to provide an improvement in the structure of the audio plug to form the ON / OFF switch of the audio plug without affecting the normal sound output of electronic products.

Another objective of this utility model is to provide an audio plug that is compliant with the specification of a 2.5 mm, 3.5 mm or 6.5 mm audio plug standard for connecting to a terminal at a predetermined position in the corresponding audio jack and providing a hollow tube for mounting an electronic element so that the audio plug has other functions than transmitting an audio signal.

In order to achieve the above objectives, improving the structure of the audio plug contains a hollow tube made of conductive materials and having a first conductive part on its front section, a first insulating part on its rear section, a front end forming a first hole, and a rear end, forming a second hole and the full outer diameter of the hollow tube, while maintaining the standard specification of the planned audio plug; a head made of insulating materials and having a front end portion, which is a conical body consistent with the audio plug of the specification, and a cylindrical connection on its rear end portion for insertion into the first hole, the front end portion protruding from the front of the hollow tube and has an axial a gap in its middle for inserting a conductive plate body, at least a side surface of the head forming the second conductive part, and the rest of the surfaces of the head, shapes a second insulating part and a second conductive part are insulated from the first conductive part of the hollow tube by a cylindrical connection; and an electronic element having a first electrode and a second electrode, respectively connected to the second conductive part and the first conductive part.

By this, when an audio plug is inserted into the audio jack of a predetermined electronic product, the first conductive part and the second conductive part are respectively electronically connected to the second terminal and the first terminal arranged in a predetermined position in the audio jack to receive power and supply power or a signal required by the electronic an element; at the same time, the first isolating part is connected to terminals other than the second terminal and the first terminal in the audio jack to avoid outputting sound from the audio jack; when the audio plug is rotated by a certain angle, the first conductive part and the second conductive part are deviated from the second terminal and the first terminal to disconnect the electrical connection between the audio plug and the audio jack.

Based on the disclosed features, the audio plug uses the composite structure of the conductive part and the insulating part and the angular rotation design to receive power or signal without affecting the normal use of the speaker of the electronic product. An ON / OFF switch is formed if the audio plug is rotated by a predetermined angle. Moreover, a predetermined electronic element may be arranged inside or outside the audio plug, and the power or signal is obtained through the audio plug to have functions other than transmitting the audio signal.

Secondly, the components in this description and the following utility model formula differ not in different terms of components, but in different functions of the components. The term “includes” or “comprises” in this description and the following utility model formula refers to an open term, which should be interpreted as “including, but not limited to.” In addition, the term “connected to” includes direct and indirect means of electrical connection. Finally, the audio plug in this utility model includes a specification for a standard audio plug 2.5 mm, 3.5 mm, 6.5 mm. However, the following embodiment illustrates the specification of a standard 3.5 mm audio plug.

Turning to FIG. 3 through 7, a preferred embodiment for improving the structure of an audio plug in accordance with the present utility model comprises: a hollow tube 30, a head 40, and an electronic element 50.

The hollow tube 30 is made of conductive materials and has a first conductive portion 31 at its front section, a first insulating portion 32 at its rear section, a front end forming a first hole 33, and a rear end forming a second hole 34 and the total outer diameter of the hollow tube 30 , saves the standard specification of the planned audio plug.

The head 40 is made of insulating materials and has a front end portion 41, which is a conical body conforming to the specification of the planned audio plug standard, and a cylindrical connection 42 on its rear end portion for insertion into the first hole 33. The front end portion 41 projects in front of the hollow tube 30 and has an axial gap in its middle for inserting a conductive plate body 44 for at least a side surface of the head 40 forming the second conductive part 44a. In this embodiment, the second conductive part 44a is formed on two corresponding side surfaces of the head 40. The remaining surfaces of the head 40 form a second insulating part 44b and the second conductive part 44a is isolated from the first conductive part 31 of the hollow tube 30 by a cylindrical connection 42.

The electronic element 50 has a first electrode 51 and a second electrode 52, respectively connected to the second conductive part 44a and the first conductive part 31. In an embodiment, the electronic element 50 includes a light emitting element 50a, a sound producing element, an electromagnetic wave element, or an optical element. FIG. 3, 6A and 6B illustrate that the electronic element 50 is a light emitting element 50a, such as an LED or LD. In an embodiment, the light emitting element 50, 50a is arranged in the hollow tube 30 and has a needle 51a and a base 52a as the first electrode 51 and the second electrode 52, respectively connected to the second conductive part 44a and the first conductive part 31. The interior of the hollow tube 30 can also install other electronic components according to functional requirements and will not be described in detail in this document.

With reference to FIG. 5A and 6A, the audio plug 20 is in the OFF state when the audio plug 20 is inserted into the audio jack 60; that is, the first terminal 61 of the audio jack 60 is connected to the second isolation part 44b of the audio plug 20, and the third and fourth terminal 63, 64 are connected to the first isolation part 32. Thus, even assuming that the audio plug 20 is inserted into the audio jack 60, the sound of the electronic products 70, such as a smart phone, will not be output from the audio jack 60, but from the speaker 71, which will not affect the normal use of the smart phone 70.

With reference to FIG. 5B and 6B, the audio plug 50 is ON when the audio plug 20 is rotated through an angle of 90 °; that is, the first conductive part 31 and the second conductive part 44a are respectively electronically connected to the second terminal 62 and the first terminal 61. Thus, the light emitting element 50a is powered by the first electrode 51 and the second electrode 52 and emits light from the light emitting slot 351 of the sealed cover 35 to form a laser pointer or light emitting pen, as shown in FIG. 7 to perform a presentation or training.

By this, when the audio plug 20 is inserted into the audio jack 60 of the predetermined electronic product 70, the first conductive part 31 and the second conductive part 44a are respectively electronically connected to the second terminal 62 and the first terminal 61 arranged in a predetermined position in the audio jack 60 for receiving power and supplying the power or signal required by the electronic element 50; at the same time, the first insulating part 32 is connected to terminals other than the second terminal 62 and the first terminal 61 in the audio jack 60 to avoid outputting sound from the audio plug 60; when the audio plug 20 is rotated by a certain angle, the first conductive part 31 and the second conductive part 44a are deviated from the second terminal 62 and the first terminal 61 to disconnect the electrical connection between the audio plug 20 and the audio jack 60.

With reference to FIG. 3B, the first conductive portion 31 has a small area forming an insulating surface 311 on its surface. The insulating surface 311 is designed for some market mobile phones, such as SAMSUNG mobile phones having a second terminal and circuit design (not shown) in an audio jack. When the audio plug 20 is rotated through a certain angle to form an OFF state, not only the first terminal 61 is connected to the second insulating part 44b, but also the second terminal 62 is connected to the insulating surface 311 to form a non-conductive circuit. Thus, when answering an incoming call, the audio signal is transmitted not to the headphone jack, but to the speaker 71. However, the insulating surface 311 is not required.

Therefore, the present utility model discloses an audio plug 20 corresponding to an existing audio jack 60 of 3.5 mm electronic products to hide the LD or LED in the headphone jack.

FIG. 3C and 6C illustrate another embodiment of the present utility model. The electronic element 50 is arranged outside the hollow tube 30 and has two lead wires as the first electrode 51 and the second electrode 52 respectively connected to the second conductive part 44a and the first conductive part 31. The above embodiment uses similar means to rotate the audio plug 20 so that the electronic element 50 could receive power from the audio jack 60 or turn off the power. With reference to FIG. 4A and 6C, the second hole 34 of the hollow tube 30 may include a sealed modeling cover 36, as shown in FIG. 6C, or an elongated sealed cover 37, as shown in FIG. 4B, and the electronic element 50 is arranged inside the sealed modeling cap 36 or the elongated sealed cover 37, and the electronic element 50 can be arranged inside the hollow tube 30.

Based on the disclosed features, the audio plug 20 uses the composite structure of the conductive part and the insulating part and the angular rotation structure to receive power or signal without affecting the normal use of the speaker of the electronic product. An ON / OFF switch is formed if the audio plug is rotated by a predetermined angle. Moreover, a predetermined electronic element can be arranged in the inner part or (on) the outer part of the audio plug and the power or signal is received by the audio jack to have other functions than transmitting the audio signal.
