Description

speakerphone mechanism

The utility model relates to a telephone, in particular to a "hands-free receiver mechanism".

In today's society, mobile phones have become a necessary communication tool in daily life, but it is very inconvenient to hold a mobile phone to talk and have to stop the work at hand. According to reports, the electromagnetic waves of mobile phones will directly or indirectly affect human health. Earphone-type mobile phone with hands-free function has been developed. The earphone device is inserted into the earphone jack or connected to the charging place of the mobile phone. The length obviously still makes the user very inconvenient, and putting the earphone cover on the ear for a long time will also cause an extremely uncomfortable feeling, and another company refits the mobile phone to have a hands-free function, but the modified action It may destroy the original functions of the mobile phone and not meet the economical effect, and all these deficiencies have been troubled by the people all the time.

In view of the shortcomings derived from common products, the inventor of the utility model devoted himself to research and innovated and improved it, and finally successfully developed and completed the hands-free receiver mechanism.

The purpose of the utility model is to provide a hands-free receiver mechanism, which can easily talk anytime and anywhere without holding a mobile phone, and can stay away from radio waves and radiation.

Another object of the present invention is to provide a hands-free handset mechanism. The mobile phone does not need to be complicatedly refitted and is economical, and has the functions of automatic answering and hands-free operation.

The utility model is a hands-free receiver mechanism, which comprises: a battery back cover, on which a round hole and a through hole are opened; a speaker; a circuit board, on which a power amplifier circuit is provided; The earphone plug device has a microphone embedded in it and a pin is fixed under it; a wire is connected between the circuit board and the earphone plug device for signal transmission, and is characterized in that the loudspeaker is fixed behind the battery On the round hole of the cover and its coil contacts are connected to the circuit board, the circuit board is also connected to the mobile phone, the wire connected to it passes through the through hole of the battery back cover, and the earphone plug device connected to the wire The pin below it is inserted into the earphone holder on the mobile phone.

The above-mentioned purpose of the utility model and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model;

Fig. 2 is the three-dimensional assembly drawing of the present utility model;

Fig. 3 is a partial sectional view of the utility model;

Fig. 4 is a block diagram of the utility model;

Fig. 5 is a circuit diagram of the utility model.

The utility model provides a hands-free receiver mechanism, please refer to Fig. 1, Fig. 2 and Fig. 3, which are three-dimensional decomposition, three-dimensional combination, and partial cross-sectional views of the present utility model, and a round hole 101 is opened on the battery back cover 10 And a through hole 102, the loudspeaker 2 is fixedly placed on the round hole 101 of the battery back cover 10 and its coil contacts of the loudspeaker 2 are connected with the circuit board 3 (the prior art), and the circuit board 3 has a power amplifier circuit 31 , and a SIM card slot 32 is set on the circuit board 3 for inserting the SIM card, the wire 4 passes through the through hole 102 of the battery back cover 10 and is connected with the circuit board 3 and the earphone plug device 5, the earphone plug device A microphone 51 and a capacitor 52 are embedded in the 5, and a pin 53 is fixed under it, and the pin 53 is inserted into the earphone holder 11 on the mobile phone 1, and a flexible cable 33 is connected to the circuit board 3 and Connect a shared circuit board 34, the shared circuit board 34 has the same shape and size as a general SIM card, the shared circuit board 34 is inserted into the fixed slot 12 of the mobile phone 1, and the circuit board 3 is connected to the fixed slot 12 by a flexible cable 33. The set SIM card slot 32 is connected to the mobile phone 1. Due to the softness of the flexible cable 33, the battery 6 placed therein can be placed in the mobile phone 1 stably without affecting the battery back cover 10. snap fit.

Please refer to Fig. 4 and Fig. 5, which are block diagrams and circuit diagrams of the present utility model. The user's voice is collected by the microphone 51 and the voice signal enters the mobile phone 1 through the plug 53 so that the person talking with it can receive it, and the mobile phone 1 The caller's voice signal is transmitted to the circuit board 3 through the earphone plug device 5 through the wire 4 , and then through the circuit 31 with power amplification, and then the sound is emitted through the speaker 2 .

Because the mobile phone of the present invention can hear the voice of the caller clearly without holding or using a traditional earphone, it can be easily and freely talked anytime, anywhere, regardless of whether it is working or driving, and it can be Keep away from the interference of electric waves and radiation to ensure the health of the user, and use the space inside the battery back cover to expand to have a hands-free handset function, without complicated modification of any precision parts inside the mobile phone, neither destroying the original functions of the mobile phone It is also in line with the economic effect.

To sum up, the hands-free receiver mechanism provided by the utility model can easily talk anytime and anywhere without holding a mobile phone, and can also stay away from radio waves and radiation, and does not require additional complicated modifications, which is economical and has a The functions of automatic answering and hands-free operation do meet the requirements for patent approval. I file a patent application in accordance with the law and pray for the patent to be granted. I am really grateful.

But what is described above is only a preferred and feasible embodiment of the utility model, and all changes made by using the above-mentioned method, shape, structure, and device of the utility model should be included in the scope of rights of the utility model Inside.
