Description
Technical Field
The invention relates to the technical field of design of external horn circuits of mobile phones, in particular to a design method of an external horn circuit of a mobile phone.
Background
In modern society, mobile phones, namely mobile phones, become indispensable communication tools for people, functions of mobile phones are more and more powerful, requirements of consumers on performance of various aspects of mobile phones are more and more high, and in order to be convenient to use, many consumers require mobile phones to have a hands-free function like a fixed phone, and the requirements are particularly important under the condition that driving or other tools and devices are operated and cannot be stopped.
Through retrieval, the hand-free function of the existing mobile phone generally adopts a built-in micro-speaker of the mobile phone to play audio signals, and the built-in micro-speaker of the mobile phone has smaller volume and smaller played sound because of the limitation of the volume of the mobile phone, and the sound effect is not very good, especially difficult to hear in a noisy environment. Affecting normal listening.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a design method of an external horn circuit of a mobile phone.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a design method of an external horn circuit of a mobile phone comprises the external horn circuit of the mobile phone, wherein a mobile phone audio circuit board, a hands-free control module, a frequency modulation FM transmitting device and an FM receiving device are arranged in the external horn circuit of the mobile phone.
Furthermore, the hands-free control module sends out an audio signal from the FM transmitting device according to the instruction requirement of a user, and the FM receiving device receives the signal and plays the signal.
Further, the audio signal comprises a voice signal received by the mobile phone and a voice signal sent by a user of the mobile phone.
The design method of the external horn circuit of the mobile phone further comprises the design scheme of the external horn circuit of the mobile phone, and specifically comprises the following steps:
the first step, the hands-free control module receives and judges whether the user instruction requires the mobile phone to enter a loudspeaker external release mode, if so, the second step is executed; otherwise, answering the call in a normal mode;
the second step, the hands-free control module sends the received audio signal from the FM transmitting device;
and thirdly, the FM receiving device receives the signal and plays the signal.
The beneficial effects of the invention are as follows:
1. when the mobile phone calls, if the hand-free function is needed to be selected, the user should perform corresponding operation on the operation interface of the mobile phone, when the hand-free control module detects and receives a user instruction at any time, the hand-free control module judges whether the user requires the mobile phone to enter a hand-free mode or not when receiving the user instruction, and if so, the hand-free control module sends out a received voice signal by the FM transmitting device; the FM receiving device can receive the signal and play the signal through a loudspeaker of the FM receiving device, and the hands-free function is realized, so that convenience is brought.

fig. 2 is a schematic structural diagram of a design method of an external speaker circuit of a mobile phone according to an embodiment.
Detailed Description
In order to further describe the technical means and effects adopted by the present invention for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
Examples
Referring to fig. 1, a design method of an external speaker circuit of a mobile phone is characterized by comprising the external speaker circuit of the mobile phone, wherein a mobile phone audio circuit board, a hands-free control module, a frequency modulation FM transmitting device and an FM receiving device are arranged in the external speaker circuit of the mobile phone.
The hand-free control module sends out an audio signal according to the instruction requirement of a user by the FM transmitting device, the FM receiving device receives the signal and plays the signal, and the audio signal comprises a voice signal received by a mobile phone and a voice signal sent by a mobile phone user.
In addition, the design method of the external horn circuit of the mobile phone further comprises the design scheme of the external horn circuit of the mobile phone, and specifically comprises the following steps:
the first step, the hands-free control module receives and judges whether the user instruction requires the mobile phone to enter a loudspeaker external release mode, if so, the second step is executed; otherwise, answering the call in a normal mode;
the second step, the hands-free control module sends the received audio signal from the FM transmitting device;
and thirdly, the FM receiving device receives the signal and plays the signal.
Working principle: if the hand-free function is required to be selected, the user should perform corresponding operation on the operation interface of the mobile phone, when the hand-free control module detects and receives a user instruction at any time, the user is judged whether to require the mobile phone to enter a hand-free mode or not when the user instruction is received, and if the user instruction is received, the hand-free control module sends out a received voice signal by the FM transmitting device; the FM receiving device can receive the signal and play the signal through a loudspeaker of the FM receiving device, and the hands-free function is realized, so that convenience is brought.
While the present invention has been described in terms of preferred embodiments, it should be understood that the present invention is not limited to the preferred embodiments, but is intended to be limited to the specific embodiments disclosed herein, and that any person skilled in the art may make various changes or modifications to the embodiments without departing from the scope of the present invention, and any modification, equivalent and variation to the embodiments described above according to the technical matter of the present invention may still fall within the scope of the present invention, and at the same time, all the standard parts used in the present invention may be purchased from the market, all the special parts may be customized according to the descriptions of the specification and the drawings, all the specific connection modes of the parts may be conventional means such as bolt rivets and welding, all the mechanical, part and equipment may be conventional types in the prior art, and all the connection modes may be conventional in the prior art, which are not described in detail herein.
