Description

Dual purpose mobile phone earphones {DUAL PURPOSE MOBILE PHONE EARPIECE}

The present invention relates to a dual purpose earphone for a mobile phone, and more specifically a mobile phone which is designed to be worn around the user's neck to capture throat vibration sonic waves and verbal sonic waves. The present invention relates to earphones.

Various types of mobile phone microphones are currently available on the market. One of them is to hang around the neck of the user to receive sound waves generated in the throat. Such mobile phone microphones are still modifying the microphone structure of the prior art (see Fig. 1). When people speak, sonic vibrations from the throat are transmitted to the microphones, which are then sent to the circuit through the springs for amplification and broadcasting. Using spring as a transmission medium takes up a lot of space. However, the transmission volume is relatively small. As a result, the audio quality is relatively poor and weak. Moreover, microphones adapted from the prior art generally have only one function and cannot effectively utilize the sound generated from the throat to produce the best audible range quality possible. These microphones cannot be variously modified to have good results, and as a result have limitations in their application.

In view of the above disadvantages, it is an object of the present invention to provide a dual purpose earphone for a mobile phone capable of receiving sound wave vibrations generated from the throat and mouth to be used in a wide range of cases.

The microphone according to the present invention includes a neck band used to hang the user's neck and a main body used to attach to the user's throat at a selected position. The main body is provided with two types of circuits. One type of circuit is located on the inner side to receive sound wave vibrations generated from the throat. Another circuit is located on the outer side to receive the oral sound wave. These two circuits can be switched with each other by a control switch. The control switch is engaged with a movable cap located on the outer side of the main body to bring the switch into the desired state. The movable cap is also provided with a sonic inlet that can be opened or closed to receive various types of sonic sources to perform the desired function.

The present invention is intended to achieve the following actions and effects.

1. The present invention can receive sound wave vibrations and react directly to sound waves so that they can be switched to two desired functions according to requirements under various circumstances.

2. In this design, the movable cap is used to operate the control switch to perform the switch function. In addition, the present invention is controlled by synchronizing the opening or closing of the sound wave inlet. Thus, it is possible to block external noise and to reach a higher fidelity level of the quality of the received sound.

3. The movable cap is located on the outer side of the main body and can be moved and easily rotated to bring the switch to the desired state. So it is easy and convenient to use.

With the following detailed description and drawings, the present invention with particular advantages will be understood in detail. The drawings are for reference only, and are for illustrative purposes only, and are not intended to limit the scope of the present invention.

2 and 3, the present invention includes a microphone main body 2 mounted at one end of a neck band 20 used to hang on the user's neck in use (also in FIG. 6). Shown). The main body 2 is attached to the user's neck at the selected position. The main body 2 is provided with two shells. The inner shell 3 is attached to one side of the sponge 4, which has another side in contact with the sound generating material 5 (such as rubber for example). An annular gap ring 50 is formed between the inner shell 3 and the sponge 4. The sound generating material 5 is also attached to a layer of dumping material 6 to block noise. Above this dumping material 6 a sonic circuit 7 is located. The acoustic circuit 7 (shown in FIG. 4) comprises a metal conductive sheet, upper and lower piezoelectric ceramic elements, a circuit board, and an amplifier, and other acoustic circuits ( 7 '). These circuits 7 and 7 'are coupled to a control switch 70 that controls the switching function. The control switch 70 is inserted and fixed between a pair of lugs 80 protruding from the movable cap 8. The movable cap 8 is attached with a luminescent microphone around its inner circumference. Thus, when the movable cap 8 is rotated, the control switch 70 can also be moved so that the switch is in a desired state. The movable cap 8 is also provided with a sonic inlet 81 formed in the circumferential rim which mates with the bore 21 of the main body 2.

When the main body 2 is operated to receive sound wave vibrations generated from the throat, the inner shell 3 is closed by pressure, and the sound wave inlet 81 is moved away from the bore 21 to It is closed to prevent noise from entering the main body. Thus, the microphone becomes more sensitive to sonic vibrations generated from the throat so that the desired audible range result can be obtained. If it is necessary to move the movable cap 8 and the control switch 70 (shown in FIG. 5) to receive verbal sonic sound and switch to a circuit for direct sound wave reception conditions, The sonic inlet 81 is also moved to coincide with the bore 21 so that a result can be obtained, and the oral sonic will then enter the main body 2 through the sonic inlet 81. Thus, by the above-described configuration, the present invention can produce two different effects that can satisfy various purposes in various cases.

7 and 8 show another embodiment of the present invention. It is provided with two main bodies 2 'and 3' disposed at both ends of the neck band, respectively. One main body 2 'is provided with a circuit for receiving sonic vibration of the throat, and the other main body 3' is provided with a circuit for directly receiving sound waves of the oral cavity. Switching between these two circuits can be achieved by pressing the control switch. Thus, one circuit can be turned on and the other circuit can be turned off so that the microphone can be switched and flexibly used for various cases.

In addition, the main body 2 of the present invention is also adapted (as shown in FIGS. 9 and 10) to be used with a wireless walkie talkie 92 (or a handset of a cellular phone) via a converter 9. Can be. The converter 9 is provided with two coaxial plugs 90 and 91 and can be adjusted at various intervals to suit various jacks (shown in FIG. 11).

Thus, it can be seen from the above description that the objects as well as the objects of the present invention mentioned above can be effectively achieved. Although a preferred embodiment of the present invention has been described for the purpose of disclosure, it will be apparent to those skilled in the art that various changes or modifications may be made in accordance with the embodiment. Thus, the appended claims are intended to cover all embodiments without departing from the spirit and scope of the present invention.
