The preferred embodiment is as follows:

the utility model provides a mobile phone hand-free receiver device with voice recording and playing functions, which mainly transmits the voice signal of a mobile phone 1 through a hand-free receiver mechanism 2; the hands-free handset mechanism 2 comprises: an external receiver 20, one end of which can be connected with the cigarette lighter base of the car (i.e. the power plug 25 that can be plugged in the cigarette lighter base), the other end of which is connected with the mobile phone 1 by a connector 23, and the external receiver 20 itself has a speaker 201 and is connected with the microphone 22 by a connecting end 202, and the audio signal at the other end can be played outside by the speaker 201, and the audio signal at the other end is inputted into the mobile phone 1 from the microphone 22 to be transmitted to the other end, which are the same as the prior art.

Referring to fig. 2, a universal assembly 30 with recording and playing functions is connected to a signal line (at either end of the head or the tail) between the external receiver 20 and the connector 23, the universal assembly has a housing, two recording and playing buttons 301 and a recording indicator 302 (in the form of a light emitting diode) are exposed from the internal universal assembly 42 on the surface of the housing, and the voice signals at the end and the other end can be recorded and played by using (at least one) audio storage chip 6 by pressing the buttons 301.

For easy understanding, the combination of the general components and the receiver circuit is shown in fig. 3, the audio storage chip 6 has two audio output/input terminals, two recording/playback control terminals, and a display terminal of the recording led type indicator light 302; when the recording button 301 is not pressed, only the handset-free mechanism 2 operates in the following manner: the voice signal of the receiver is inputted from the microphone 22 and directly transmitted to the other terminal's receiving site through a microphone amplifying circuit 9, where the other terminal can listen to the voice signal; the voice signal of the other terminal is transmitted to a buffer circuit 7 via the other terminal signal A, amplified by an audio amplifier circuit 8, and output from the speaker 201 after being adjusted in volume by a Variable Resistor (VR). Wherein the buffer circuit 7 functions as "1". The other end sends signal A, and [ (2) ]. The reproduced data from the audio storage chip 6 can enter the audio amplifier 8 at the same time, and the two signals are amplified by the amplifier 8 and outputted from the speaker 201 after the volume adjustment (VR).

As shown in FIG. 3 and FIG. 2, when some other end signal A is used as input and important information is to be recorded, the recording button 301 is pressed to activate the recording control terminal of the audio storage chip 6, so that the other end signal A from the other end and the amplified already-end voice signal from the microphone 22 are combined by a voice signal mixing circuit 5 and then sent to the input terminal of the audio storage chip 6 for recording and storing; when the playback button 301 is pressed to activate the playback control end, the content recorded in the audio storage chip 6 is outputted to a buffer circuit 7 and an audio amplifier circuit 8 through the output end, and then outputted to the speaker 201 through a volume adjustment. If there is other end sending signal A and inputting to the buffer circuit 7 at the same time, the circuit can make the two signals enter the audio amplifier 8 at the same time, the amplifier 8 amplifies the two signals together, and outputs from the loudspeaker 201 after the volume adjustment (VR); that is, the playback signal can be input into the buffer circuit 7 together with the voice signal of the other end transmission A, and then output to the speaker 201 through the audio amplifier circuit 8, so that the audio amplifier circuit 8 can be used for directly amplifying the other end voice signal and outputting the audio signal when the audio storage chip is triggered at the playback control end.

Of course, the audio storage chip 6 can be a single high capacity type, or can be connected in parallel by using a plurality of low capacities. Moreover, a microprocessor 61 can be added to the audio storage chip 6 to control the audio storage location of the audio storage chip 6; the microprocessor 61 can further add a Memory 62 capable of recording the storage location and length of the audio storage chip 6, which is an EEPROM (Electronic Erase Program on Memory) type that is not erased when power is off, so that the location and length stored therein will not be erased when power is off, and the audio storage chip is also a type that is not erased when power is off, and functions as a general hard disk drive. During recording, the microprocessor 61 can control the recording position (i.e. the position after the previous recording) and the memory 62 can memorize the recording position and the recording length; during playback, the microprocessor 61 captures the position of starting recording and outputs the recording content.

As shown in fig. 4, the universal assembly 30 can be installed in the external receiver 20 or any structure of the connector 23, and the button 301 and the indicator light 302 are exposed because the surfaces of the two structures have through holes corresponding to the positions of the button 301 and the indicator light 302 of the universal assembly 30.

As shown in FIG. 10, the universal component body 30 with recording and playing functions of the present invention can also be disposed in other configurations like the following hands-free device of mobile phone for automobile:

one configuration mode comprises a fixed seat 35 with a hand-free receiver and a charging function, a power supply plug 25, a microphone 22 and a mobile phone 1, wherein the fixed seat 35 is used for fixing the mobile phone 1 and can be arranged at the side of an instrument board near a steering wheel, the fixed seat is provided with a loudspeaker 201, the interior of the fixed seat is provided with a hand-free receiver circuit originally arranged in an external receiver 20, and the lower side of the fixed seat is connected with the power supply plug 25 connected to a cigarette lighter seat through a connector, so that the power supply and charging effects are achieved; and a microphone 22 is inserted into one side of the fixing base to match the above structure to achieve the function of hands-free device. The universal assembly 30 of the present invention is installed at the bottom of the structure of the fixing base 35, and the recording/reproducing button 301 and the recording/reproducing indicator light 302 are exposed through the through hole at the bottom surface of the fixing base.
