Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 2 is a schematic diagram illustrating a structure of an electronic device according to an exemplary embodiment, as shown in fig. 2, including a processor 201, a speech processing device 202, a first switching device 203, a high fidelity audio processing device 204, a second switching device 205, and an audio output device 206.
Wherein, the input end of the voice processing device 202 is connected with the processor 201, the output end of the voice processing device 202 is connected with the first switching device 203, the first switching device 203 is connected with the audio output device 206, the input end of the high fidelity audio processing device 204 is connected with the processor 202, the output end of the high fidelity audio processing device 204 is connected with the second switching device 205, and the second switching device 205 is connected with the audio output device 206.
In the embodiment of the disclosure, the electronic device has a voice call function and an audio playing function, and can be a mobile terminal. The mobile terminal may be a smart phone, a tablet computer, or the like, which is not particularly limited in this disclosure. Wherein the processor 201, the voice processing device 202, the first switching device 203, and the audio output device 206 constitute a voice processing circuit. The processor 201, the hi-fi audio processing device 204, the second switching device 205, and the audio output device 206 form a hi-fi audio processing circuit, where the audio output device 206 includes an earphone and may also include a speaker, and the embodiment of the present disclosure is not particularly limited in this respect.
In the voice communication process, the voice processing circuit is responsible for processing the voice signal. During processing of the speech signal, the first switching device 203 is in a closed state and the second switching device 205 is in an open state, so that the circuit between the audio output device 206 and the second switching device 205 is in an open state; the voice processing device 202 decodes the voice signal, and transmits the decoded voice signal to the audio output device 206 through the first switching device 203, and the audio output device 206 plays the received voice signal.
It should be noted that the first switching device 203 has two states: an open state and a closed state. When the first switching device 203 is in the off state, the circuit between the voice processing device 202 and the audio output device 206 is not connected; when the first switching device 203 is in a closed state, the circuit between the speech processing device 202 and the audio output device 206 is connected. The second switch device 205 is in the off state means that the second switch device is in the high-resistance state, and at this time, if a voice signal is transmitted from the first switch device 203 to the audio output device, because the second switch device 205 is in the high-resistance state, the voice signal directly flows to the audio output device with lower resistance, but does not flow to the second switch device 205 in the high-resistance state, that is, the circuit between the audio output device 206 and the second switch device 205 is in the off state, thereby avoiding the problem that the second switch device 205 is damaged due to the voice signal flowing to the second switch device 205, and simultaneously, not affecting the tone quality of the voice signal received by the audio output device.
In the audio playing process, the high fidelity audio processing circuit is responsible for processing audio signals, which include music, recording, and the like, and this is not specifically limited in the embodiments of the present disclosure. In the process of processing the audio signal, the high fidelity audio processing device 204 performs digital-to-analog conversion on the received digital audio signal, and outputs the obtained analog audio signal to the second switching device 205; the second switching device 205 amplifies the analog audio signal output by the hi-fi audio processing device 204 and transmits the amplified analog audio signal to the audio output device 206, and the audio output device 206 plays the received audio signal.
It should be noted that, during the non-audio signal processing, the hi-fi audio processing device 204 is in the non-operating state, and the hi-fi audio processing device 204 is in the high impedance state when in the non-operating state. The first switching device may be in an open state when the second switching device 205 is transmitting an audio signal to the audio output device 206.
In the embodiment of the present disclosure, the electronic device controls the second switching device 205 to switch to the off state when detecting that the designated pin of the second switching device 205 is at a low level. Wherein the designated pin is a disable pin. Fig. 3 is a pin diagram of a second switching device 205, which includes a 1-output terminal, a 2-negative power input terminal, a 3-in-phase signal input terminal, a 4-reverse signal input terminal, a 5-enable terminal, and a 6-positive power input terminal, wherein a signal is input from the 3-in-phase signal input terminal or the 4-reverse signal input terminal, and when a signal is input from the 3-in-phase signal input terminal, the phase of the signal output from the 1-output terminal is identical to the phase of the input signal; when a signal is input from the 4-inversion signal input terminal, the phase of the signal output from the 1-output terminal is 180 degrees different from that of the input signal. The 2-negative power supply input end is connected with a negative power supply or grounded, and the 3-positive power supply input end is connected with a positive power supply. The 5-enable terminal is a disable pin, and when the second switching device 205 is in a non-operating state, the disable pin can be set to a low level, so that the second switching device is in a high-resistance state, and the power consumption of the second switching device 205 is as low as a few microamps and can be ignored, thereby reducing the power consumption of the electronic device.
According to the electronic equipment provided by the embodiment of the disclosure, the output end of the voice processing device is connected with the first switch device, the output end of the high-fidelity audio processing device is connected with the second switch device, and the second switch device is connected with the audio output device; in the process of processing the voice signal, the first switch device is in a closed state, and the second switch device is in an open state, so that a circuit between the audio output device and the second switch device is in an open state. Because the second switch device is directly connected with the audio output device, the problem of tone quality loss caused by adding other devices in the second switch device and the audio output device is avoided, and the tone quality of the audio signal output by the electronic equipment is high.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
