Embodiment
Below in conjunction with the drawings and specific embodiments the system and method for intelligent terminal audio frequency acquiring signal that utilizes provided by the invention is described in detail.
Fig. 3 shows the calcspar according to an embodiment of system of the present invention.Followingly one embodiment of the present of invention are described with reference to Fig. 3.In this embodiment, utilize the system of intelligent terminal audio frequency acquiring signal can comprise three parts: checkout equipment, intelligent terminal and be connected checkout equipment and intelligent terminal between the audio signal sample device.
What wherein checkout equipment can be that fetus-voice meter, electrocardiogram equipment, electronic auscultation device or other are any in can the equipment of output audio signal is a kind of, and this checkout equipment has at least one output channel, is used for output audio signal.Intelligent terminal can be the terminal that comprises the IOS type of IPHONE for example or IPAD, also can be to comprise for example terminal of type such as Android, and this intelligent terminal has at least one input channel that is used for input audio signal.
The audio signal sample device can be connected with the form of lead between checkout equipment and the intelligent terminal, but, this audio signal sample device also can be connected between checkout equipment and the intelligent terminal with other form, as long as this device can be gathered from the sound signal of checkout equipment output, make intelligent terminal that it is identified as the sound signal input media, also this sound signal is input to intelligent terminal, this lead can be silver-plated stranded conductor or shielding line.
This audio signal sample device comprises the equipment adaptation module that is connected to checkout equipment and the terminal adaptation module that directly or indirectly is connected with this equipment adaptation module.
Wherein the equipment adaptation module is used to detect the type of checkout equipment, and handles accordingly according to detected type, and this will describe below more specifically.
The terminal adaptation module also is connected to intelligent terminal by at least one input channel, make intelligent terminal that the audio signal sample device is identified as external sound signal input media (for example microphone etc.), thereby allow to input to intelligent terminal by this input channel from the sound signal of checkout equipment, so that record, rather than record from the microphone that intelligent terminal carries in this input channel.In addition, for the sound signal that obtains good quality more or be user-friendly to, the terminal adaptation module can also comprise other functions such as filtering, broadcast.
In addition, as shown in Figure 3, the audio signal sample device can also comprise module and/or additional function modules are set.
Module is set is connected between equipment adaptation module and the terminal adaptation module, be used to set/change the configuration (for example, can adjust the capacitance, resistance value etc. of the device in the audio signal sample device) of audio signal sample device.
Additional function modules can comprise control module, broadcast or monitor module, graph image display module and/or track selecting module or the like, thereby can audio plays, shows signal power, show waveform signal or the like.
Below, illustrate that with reference to Fig. 4 the intelligent terminal of system is the situation of IPHONE according to an embodiment of the invention.In this example, checkout equipment can be fetus-voice meter, and intelligent terminal is IPHONE, and the audio signal sample device is connected between fetus-voice meter and the IPHONE with the form of lead.An end that wherein has the equipment adaptation module in the audio signal sample device can be inserted in the output channel of fetus-voice meter by plug, so that the equipment adaptation module is connected with fetus-voice meter, and an end that has the terminal adaptation module in this audio signal sample device can be inserted in the input channel of IPHONE by plug, so that the terminal adaptation module is connected with IPHONE.Like this, provide at fetus-voice meter under the situation of output of two-channel, can select the output channel of a sound channel of fetus-voice meter as sound signal, also can use the output channel of another one sound channel, perhaps two sound channels are superimposed as the output channel of sound signal as sound signal; And present IPHONE only provides single pass recording input, therefore, can use the input channel of this single channel as input audio signal.But,, then also can select multichannel recording input if recording side (intelligent terminal side) can provide multichannel input.
In the present embodiment, the audio signal sample device can have wire form, and the length of lead and material can be determined or adjust as required, for example can adopt silver-plated stranded conductor, perhaps uses shielding line etc.But the present invention is not limited to this, and the audio signal sample device also can have other arbitrary shapes such as other form, for example box-like, sphere.
In this audio signal sample device, the equipment adaptation module can be a capacitor C, and the terminal adaptation module can be a resistance R.The value of capacitor C can be adjusted according to the type of checkout equipment, and the value of resistance R also can be adjusted according to the type and the customer demand of intelligent terminal.Value shown in Fig. 5 is the reference value of the value of above-mentioned components and parts only, in actual conditions, can adjust and optimizes these values, makes total system to take into account factors such as cost and profile on the basis of operate as normal.
And, in audio signal sample device shown in Figure 4, do not have the module of setting and additional function modules.
Below, illustrate that with reference to Fig. 5 intelligent terminal is another example of the system of IPHONE.In this example, its structure is basic identical with example shown in Figure 4 substantially, difference is that the equipment adaptation module in the audio signal sample device is the polarity free capacitor of the good stability that electrochemical capacitor constituted of two series connection, and this device had both gone for comprising the IOS terminal device of IPHONE and IPAD, also went for a lot of Android equipment (comprising mobile phone and panel computer).
Fig. 6 A and 6B have shown the example that comprises the audio signal sample device that module is set.In Fig. 6 A and 6B, module is set can comprises double-point double-throw switch, therefore, circuit that can be different, thereby the suitable audio signal sample device of intelligent terminal configuration for using according to the dissimilar switchings of intelligent terminal.But the present invention is not limited to this, and the configured parts that module also can be other any can change/setting audio signal pickup assembly is set.
Fig. 7 has shown the example of the audio signal sample device that comprises additional function modules.The structure of the structure of audio signal sample device as shown in Figure 7 and audio signal sample device shown in Figure 4 is basic identical, and their difference is to have increased additional function modules between equipment adaptation module and terminal adaptation module.This additional function modules can be audio amplifier circuit and loudspeaker or earphone, and these functional modules can provide the function of playing or monitoring when recording; Additional function modules can also have the control of control, volume and the tone of opening, closing etc.; In example shown in Figure 7, chosen and amplified with the identical sound channel of recording and plays, certainly, can also select another sound channel, two sound channels, two sound channels to superpose to amplify and play.This additional function modules can also be the graph image display module, such as showing the signal power by pilot lamp, index dial, shows the characteristic of signal etc. by waveform.
It should be noted that at last, more than these embodiment only in order to describe technical scheme of the present invention rather than the present technique method limited, the present invention can extend to other modification, variation, application and embodiment on using, and therefore thinks that all such modifications, variation, application, embodiment are in spirit of the present invention and teachings.
