Embodiment 1

[0026] figure 1 It is a structural block diagram of an embodiment of an earphone supporting FM function provided by the present invention.

[0027] refer to figure 1 As shown, the headset supporting the FM function provided by this embodiment is applied to smart devices capable of providing audio output such as mobile phones, desktop computers or tablet power, and specifically includes a decoding control unit 10, a sound unit 20, a connection unit 40 and an FM demodulation chip 30 , the decoding control unit 10 is connected to the sound unit 30 , the FM demodulation chip 20 , and the connection unit 40 respectively.

[0028] The connection unit 40 is used to establish a connection with the smart device, and the connection may be a wireless connection or a wired connection.

[0029] The decoding control unit 10 includes a controller, which is used to analyze the radio control command output by the smart device received through the connection unit, convert it into an FM contro...

Embodiment 2

[0042] figure 2 It is a structural block diagram of another earphone embodiment supporting FM function provided by the present invention.

[0043]The connection unit can be a wireless connection module, so that the decoding control unit 10 can be connected with the smart device in a wireless manner. The controller in the decoding control unit 10 can perform corresponding protocol analysis on the wirelessly transmitted data, such as Bluetooth protocol analysis.

[0044] The connection unit can also be a USB interface, refer to figure 2 shown. The USB interface 41 is connected with the decoding control unit 10, and is used for connecting the decoding control unit 10 with the smart device, and outputting the radio control command output by the smart device to the decoding control unit.

[0045] The controller in the decoding control unit 10 can control the USB interface 41, that is, control the USB interface 41 to work with the smart device, send and receive various instruct...

Embodiment 3

[0049] image 3 It is a structural block diagram of another earphone embodiment supporting FM function provided by the present invention.

[0050] The FM demodulation chip 20 generally needs to receive FM broadcast signals through a relatively long antenna during operation. If the earphone is large in size (such as a head-mounted type), the antenna can be designed based on the shape of the earphone. However, for earphones with a small volume, the separate antenna arrangement will make the structure more complicated. In order to solve this problem, the earphone provided by this embodiment utilizes the connecting line 31 used to connect the decoding control unit 10 and the sound unit 30 as the antenna. .

[0051] During specific implementation, the antenna connection end 21 of the FM demodulation core 20 is connected to the connecting wire 31. Since the wire is generally longer in order to allow the user to use more comfortably, the wire can be used to achieve the purpose of re...

Abstract

The invention provides an earphone supporting a FM function. The earphone comprises a decoding control unit, a sound production unit, a connection unit and a FM demodulation chip. The decoding control unit is connected to the connection unit and the FM demodulation chip respectively. The connection unit is used for establishing connection with intelligent equipment through a wireless connection mode or a wired connection mode. The decoding control unit comprises a controller and is used for parsing a radio control instruction which is output by the intelligent equipment and is received through the connection unit, converting into a FM control instruction and sending to the FM demodulation chip. The FM demodulation chip is used for receiving a FM broadcasting signal according to the FM control instruction and outputting a FM audio signal generated by demodulating the FM broadcasting signal to the decoding control unit. The decoding control unit also comprises a decoder and is used for processing the FM audio signal and then outputting to the sound production unit so as to carry out sound production. By using the earphone, a problem that a user needs to increase data flow cost when hearing FM broadcasting can be solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an earphone supporting FM function. Background technique [0002] Mobile phones with FM function usually adopt the technical solution of built-in FM demodulation chip, and use the left and right channel connecting lines of earphones as the receiving antenna of FM demodulation chip. Due to listening habits, the use of FM functions in China has been decreasing. Most users may have never used the FM function of mobile phones, and they seldom use it as a reference factor when purchasing. Based on the above reasons, most mobile phones have canceled the FM function at present. [0003] Everything has two sides. For a small number of users, especially those in India and other markets, the FM function will still be used frequently, which causes users to only use wireless data networks to listen to FM radio. Users have increased the cost of data traffic. Contents of the...
