Description

A superslim -type telephone}

The present invention relates to a speakerphone phone, and in particular, in order to minimize the space used in the phone, a method of inserting components into a circuit board (PCB) is made ultra slim, and the speakerphone and earphone can be combined with the speakerphone. The present invention relates to an ultra-slim phone that can freely use earphones selectively.

In general, speakerphone telephones take up some space because they are not smaller than a typical landline telephone, so it is not easy to install them in a confined space such as a table for a computer work, and a small telephone (aka Saojung telephone) that can utilize a small space. There is no speakerphone function, and only the earphone function can be used, which is inconvenient because it is limited to the user's needs. In addition, the ear set used in such a conventional ultra-compact telephone cannot be fixedly mounted on the telephone, thus causing inconvenience in storage. This was followed, and the use of wall-mounted phones was limited due to their size and weight.

Accordingly, in order to reduce the size and weight of the phone, it is necessary to make the internal circuit configuration and the arrangement of components in the minimum space. As a method for this, a method of reducing the height by using a miniaturized chip component can be considered. The problem of reducing the height of a part by making the part in the form of a chip is limited in some high-capacity parts, or because of excessively high price, so that it is practically not used to produce a product. In addition, there is a method of minimizing the height by laying a component, which is generally used to reduce the height, on one surface of the circuit board (PCB) inside the phone (see FIG. 2B), but in this way, the component on the circuit board (PCB) There was a limit to lower the height of the seated state.

The present invention has been devised in view of the above-mentioned problems, and is easy to install in a narrow space by making a slimmer speakerphone phone of the size of a conventional general phone by changing a part inserting method inside the phone to minimize the space inside the phone. It is easy to install on the vertical surface such as wall and wall. Also, according to the ultra slim design, it is possible to install ear set by adding earphone function instead of handset and to switch between speakerphone and earphone conveniently with both hands. Its purpose is to provide an ultra-slim phone that is configured to allow a call through a speakerphone or earset without any disruption to the work.

In order to achieve the above object, the ultra-slim phone according to the present invention includes a speaker body having a circuit board (PCB) including a phone body comprising a speaker part, a microphone part, and a dial button part, and a circuit embedded inside the body. Therefore, a hole set is inserted into a circuit board (PCB) embedded in the phone body, or a component is inserted into the edge of the circuit board (PCB), and an ear set in which an earphone and a microphone are integrally formed is a phone body. The speakerphone is automatically disconnected when the ear set is detached from the phone body during a call, and the speaker phone is automatically operated when the ear set is fixed to the body.

Such a ultra-slim phone according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an overall appearance of a super slim phone according to the present invention. As shown in FIG. 1, the body 1 of the ultra-slim phone according to the present invention has a dial button 11, a call button 12, a speaker 13, a microphone 14, an ear set 16, a speakerphone. It is composed of an earphone switching switch 15 and connected to a power source via a telephone jack 17, which is very thin compared to a conventional telephone, and allows to make a phone call using a speakerphone method or an earphone method. As it is miniaturized, the ear set 16 is mounted in place of the handset of the conventional telephone, and the speakerphone is turned ON / OFF according to the mounting or dismounting of the ear set 16 to the telephone. It is convenient to switch to earphone.

Specifically, the inside of the telephone according to the present invention is configured as shown in FIG. 2C in order to form the ultrathin phone as shown in FIG. 1 by the telephone according to the present invention. That is, generally, the inside of the telephone has a space up and down about the circuit board (PCB) 24 in the interior of the telephone body 1, as shown in FIG. The parts 21, 22, 23 are seated and the contacts protrude from the bottom, or the parts 21, 22, 23 are shown as shown in FIG. 2B to further reduce the space occupied by the parts 21, 22, 23. Is laid on a circuit board (PCB), but the present invention is to reduce the thickness of the phone by using the space above and below the circuit board (PCB), as shown in Figures 2a and 2b (PCB) ( 24, the size and shape of the side shape of the component 21, that is, the component 21 lying down, can be inserted onto the circuit board (PCB) 24 as shown in FIG. 2C. Drill the hole 25 as much as the free space so that the pin 26 of the part is soldered, and then bend the pin 26 of the part into the hole. Therefore, it is configured to protrude upward and downward about the circuit board (PCB) 24. As shown in FIG. 2C, the parts 21 are arranged in such a manner as to insert holes, and the parts 22 can insert all or part of the parts from one end of the circuit board PCB in consideration of the shape of the parts. After the space is cut, the pin 26 of the part is soldered and then the pin is bent and inserted. In FIG. 2C, the entire component is inserted when the component is inserted from one end of the circuit board PCB. However, only a part of the component may be inserted. However, if there is not enough space to drill holes on the PCB, solder the pin 26 of the component at the edge of the PCB 24 like the component 23, and then bend the pin 26. Even when the parts are laid down, the upper and lower spaces can be reduced as in the case of the parts 21 and 22. With such a configuration, the height at which the high-height components are seated on the circuit board (PCB) is significantly reduced, so that an ultra-slim phone having a very thin thickness can be constructed.

In addition, such an ultra-slim configuration makes it difficult to configure the handset as in a general speakerphone telephone, and thus, instead of the handset, it is equipped with an ear set 16 in which the earphone and the microphone are integrated as shown in FIG. Since the speaker 13 and the microphone 14 are also configured for the function, the speaker phone and the earphone can be used as both, so that the user can easily make a phone call without any trouble even when using both hands. It also allows the earset 16 to be fixed to the body of the phone for convenient use of the speakerphone and earphones, depending on whether the earset is mounted on the phone, ie whether the earset is not in use. It is configured to automatically turn on / off so that speakerphone function or earphone function can be easily switched during phone call. Specifically, as shown in FIG. 3, the circuit of the present invention includes a call switch 31, a speakerphone / earphone switching switch 32, a speakerphone circuit 34, a dial circuit 35, a speakerphone 35, and the like. Consisting of earphones 36, whereby the speakerphone / earphone changeover switch 32 is in the ON state as shown in FIG. 4A when the earset 16 is attached to the body without using a telephone. To keep the speakerphone in operation. Therefore, when a call is made and the call is pressed and the call is made, the earphone 16 is not detached from the body, that is, the speakerphone 35 is operated when the earphone function is not used. If you want to use the function of the earphone during the call or press the call switch, you can remove the ear set (16) from the body, at this time, as shown in Figure 4b the ear set to separate the body and speakerphone / Earphone changeover switch 32 is turned off (OFF) state that the speakerphone 35 is not in operation and keeps the earphone 35 is in operation to be free to choose the speakerphone function and earphone function during the call have.

According to the ultra-slim phone according to the present invention configured as described above, a hole is inserted into a circuit board (PCB) by using a space in the upper and lower parts of the phone as a component insertion method inside the phone. By adopting the method, the mounting height of the parts with high height is reduced, so that the thickness of the phone can be significantly reduced to form an ultra-slim, so it is easy to install in a space where the installation space is small or the wall is not easy to install. Instead, the handsets can be fixedly mounted to the body of the speakerphone phone, and the speakerphone can be automatically turned on or off depending on whether the earset is mounted on the body of the phone. You can make a call without any problem while using it, and the convenience of using the speakerphone and earphone is greatly increased. Treated.
