Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to reduce power consumption of a mobile terminal with a hearing aid function and increase standby time of the mobile terminal, an embodiment of the present invention provides a hearing aid device based on a mobile terminal, as shown in fig. 1, the device includes: an AP (Application Processor) 11, a DSP IC (Digital Signal Processing Integrated circuit) 12, an MIC (microphone) 13, a switch 14, a Codec15, and an HP PA (Headphone Power Amplifier) 16;
the switch 1 is used for switching between a first channel and a second channel.
The first channel includes AP11, DSP IC12, switch 14, and HP PA16 connected in sequence, where an input of DSP IC12 is connected to MIC13, and is used to implement hearing aid functions in the mobile terminal.
The second channel includes an AP11, a Codec15, a switch 14, and an HP PA16 connected in sequence, and is used to implement general audio transmission functions of the mobile terminal, such as playing music, voice call, and the like.
The Codec15 is also connected to the RCV (Receiver), and the Codec15 can also output audio signals through the RCV.
And the AP11 is used for controlling the switch 14 to be communicated with the DSP IC12 through the DSP IC12 when the hearing aid function is started, and controlling the AP11 and the Codec15 to enter an energy-saving mode.
The power saving mode is different from the operating mode, in which all functions of the AP11 and the Codec15 are turned on, and power consumption is also generated in the unused functions, which may result in a reduction in standby time of the mobile terminal. The power saving mode is to temporarily turn off the unused functions of the AP11 and the Codec15, and to significantly reduce the clock frequency, thereby achieving the purpose of power saving.
It can be understood that when the hearing aid function is turned on, the switch 14 is communicated with the DSP IC12, that is, the mobile phone implements the hearing aid function in the mobile terminal through the second channel, and the utilization rates of the AP11 and the Codec15 are low, so that the power saving mode can be entered to reduce the power consumption of the mobile terminal.
And the DSP IC12 is configured to receive the audio signal to be processed input through the MIC13, process the audio signal to be processed, and send the processed audio signal to the HP PA16 via the switch 14.
After receiving the audio signal to be processed, the DSP IC12 needs to run a signal processing algorithm for the hearing aid to complete the processing of the signal to be processed.
It should be noted that the MIC13 may be an MIC of a mobile terminal, and when the mobile terminal is used to implement a hearing aid function, the mobile terminal may be connected to an earphone, and an output signal of the HP PA16 is transmitted to the earphone to implement the hearing aid function. When the earphone is connected to the mobile terminal, the MIC of the mobile terminal can still input an audio signal.
An HP PA16 for amplifying a received audio signal.
In an implementation manner provided by the embodiment of the present invention, an output end of the HP PA is connected to the earphone interface, and after the HP PA16 amplifies the received audio signal, the amplified audio signal is transmitted to an earphone connected to the earphone interface through the earphone interface, so as to implement a hearing aid function.
Or, the HP PA16 amplifies the received audio signal and transmits the amplified audio signal to an audio playing device, such as a bluetooth headset, which is in wireless connection with the mobile terminal.
Compared with the prior art in which the Codec in the mobile terminal is used for realizing the hearing aid function, the Codec is operated for a long time to greatly increase the power consumption of the mobile terminal, and the standby time of the mobile terminal is reduced, the hearing aid device based on the mobile terminal provided by the embodiment of the invention realizes that the first channel is opened when the hearing aid function is started by arranging the DSP IC and the switch in the mobile terminal, the AP and the Codec are set to be in an energy-saving mode, and the DSP IC specially used for realizing the hearing aid function processes the audio signal to be processed.
The following describes a communication procedure between the first channel and the second channel of the mobile terminal.
A first channel: when the AP11 turns on the hearing aid function, the AP11 controls the switch 14 to communicate with the DSP IC12 through the DSP IC12, and the first channel is turned on. The MIC13 collects sound, generates an audio signal to be processed, inputs the audio signal to be processed to the DSP IC12, the DSP IC12 processes the audio signal to be processed, sends the processed audio signal to the HP PA16 via the switch 14, and amplifies and outputs the received audio signal by the HP PA 16.
It should be noted that, in the case that the hearing aid function of the mobile terminal is in the on state, if the AP11 detects that the mobile terminal is performing a voice call, the hearing aid function is turned off and switched to the second channel, and when it is determined that the voice call is ended, the hearing aid function is automatically turned on and switched to the first channel.
A second channel: when the AP11 detects that the mobile terminal is in voice communication, the hearing aid function is closed, the AP11 controls the switch 14 to be communicated with the Codec15 through the DSP IC12, and the second channel is opened. The AP11 controls the DSP IC12 to start the pass-through mode, that is, the DSP IC12 does not perform any processing after receiving the audio signal to be processed input by the MIC13, and directly sends the audio signal to be processed to the AP11 and Codec15, the AP11 and Codec15 complete the normal call function, and the audio signal of the opposite end during the voice call is sent to the HP PA16 by the Codec15 via the switch 14, and then is output by the HP PA 16. Further, when the hearing aid function is in the off state, the DSP IC12 will be in the sleep mode in the case where no voice input is required, and when voice input is required, the DSP IC12 switches to the through mode, directly transmitting a signal received from the MIC to the AP11 and/or Codec 15.
In another implementation manner provided by the embodiment of the present invention in combination with the Hearing Aid device based on a mobile terminal shown in fig. 1, on the basis of the device shown in fig. 1, the composition and connection relationship of each module in the device are described in detail, as shown in fig. 2, MIC13 is a digital MIC131 or an analog MIC132, and DSP IC12 includes an analog-to-digital converter ADC121, a digital signal processor DSP122, a digital-to-analog converter DAC123, a left channel interface (Hearing Aid-L), and a right channel interface (Hearing Aid-R), where DSP IC12 is connected to switch 14 through the left channel interface and the right channel interface.
The MIC13 is an audio receiving device of the mobile terminal, and may be a digital MIC131 or an analog MIC 132. Fig. 2 shows both the digital MIC131 and the analog MIC132, and in fact, MIC13 in the mobile terminal is one of the digital MIC131 and the analog MIC132, and there is no simultaneous operation of the digital MIC131 and the analog MIC132, so that DSP122 directly receives a digital audio signal transmitted by the digital MIC131 when MIC13 is the digital MIC131, and DSP122 receives a digital audio signal transmitted by ADC121 when MIC13 is the analog MIC 131.
In one implementation of the embodiment of the present invention, when the MIC13 of the mobile terminal is specifically the digital MIC131, the ADC121 may not be provided in the DSP IC 12.
Among other things, the clock for digital MIC131 is provided by DSP IC12, and in particular, by DSP122 in DSP IC 12.
And the DSP122 is configured to receive the digital audio signal sent by the digital MIC131, process the digital audio signal, and send the processed digital audio signal to the DAC 123.
It should be noted that the DSP122 is a low power DSP core in the DSP IC12, and can run signal processing algorithms for implementing hearing aid functions.
The DSP IC12 is designed based on the DSP122 with low power consumption, and has low power consumption in normal operation, which may be less than 5mW, so that even if the hearing aid function of the mobile terminal is turned on for a long time, the influence on the standby time length of the mobile terminal is small.
DAC123 is configured to receive the processed digital audio signal sent by DSP122, convert the processed digital audio signal into an analog digital signal, and send the analog digital signal to HP PA16 through the left channel interface and the right channel interface via switch 14.
The left channel interface and the right channel interface are two output ports of the DAC123, serve as a group of inputs of the switch 14, and are connected to the output ports of the switch 14.
In another implementation manner of the embodiment of the present invention, when the MIC13 of the mobile terminal is the analog MIC132, the ADC121 is configured to receive an analog audio signal input by the analog MIC132, convert the analog audio signal into a digital audio signal, and send the digital audio signal to the DSP 122.
The DSP122 is configured to receive the digital audio signal sent by the ADC121, process the digital audio signal, and send the processed digital audio signal to the DAC 123.
DAC123 is configured to receive the processed digital audio signal sent by DSP122, convert the processed digital audio signal into an analog digital signal, and send the analog digital signal to HP PA16 through the left channel interface and the right channel interface via switch 14.
The above is an introduction to the composition and functions of the DSP IC12, and in addition, the embodiment of the present invention will be described with reference to fig. 2, with regard to the connection relationship between the parts in the hearing aid device based on the mobile terminal.
The AP11 is connected to the DSP IC12 via an I2C (Inter-Integrated Circuit, two-wire serial bus) interface, the DSP IC12 further includes a control pin, and it should be noted that the switch 14 in the embodiment of the present invention may be a DPDT (Double Pole Double Throw) analog switch.
The I2C interface is used for transmitting a control instruction sent by the AP11 to the DSP IC12 and transmitting a control result fed back by the DSP IC12 to the AP 11.
The control pin is connected with the DPDT analog switch and used for controlling the connection state of the DPDT analog switch 14 according to a control instruction sent by the AP11 to the DSP IC12, when the control function of the mobile terminal is started, the DSP IC12 sets the level of the control pin to be a first level according to the control instruction sent by the AP11, and the DPDT analog switch 14 is communicated with the left channel interface and the right channel interface; when the control function of the mobile terminal is turned off, the DSP IC12 sets the level of the control pin to the second level according to the control command sent by the AP11, and the DPDT analog switch 14 is connected to the Codec 15.
In addition, the DSP IC12 is connected to the AP11 and the Codec15 via a slim Bus (Serial Low-power Inter-chip Media Bus) interface or an I2S (Inter-IC Sound, integrated circuit built-in audio) interface.
The SlimBus interface or I2S interface is used to transfer audio data between the DSP IC12 and the AP11, and to transfer audio data between the DSP IC12 and the Codec 15.
For example, when the mobile terminal needs to perform a voice call, the AP11 turns off the hearing aid function of the mobile terminal and controls the DSP IC12 to switch to the pass-through mode, and the audio signal input by the MIC13 is generated by sound collected from the outside, and at this time, after the DSP IC12 receives the audio signal input by the MIC13, the audio signal is not processed, but transmitted to the AP11 and the Codec15 through the slim bus interface or the I2S interface.
It should be noted that the audio data transmitted between the DSP IC12 and the AP11 and the audio data transmitted between the DSP IC12 and the Codec15 are not limited to the audio signal input by the MIC13, and may be other audio data. For example, in one implementation, when the hearing aid function is turned on, the AP11 and Codec15 may also send audio data to be played by the mobile terminal to the DSP IC12, and the audio data is processed by the DSP IC12 and then output through the DPDT analog switch 14 and the HP PA 16.
It should be noted that, in the embodiment of the present invention, since the HP PA16 processes an analog signal, a DAC is further provided in the Codec 15.
In addition, since the DSP IC12 cannot actively communicate with the AP11, the DSP IC12 further includes an interrupt output port in the embodiment of the present invention.
DSP IC12 for sending an interrupt message to AP11 through an Interrupt (IRQ) output port, the interrupt message for requesting communication to AP 11.
For example, when the DSP IC12 fails, it may not report the failure to the AP11 actively, and needs to send an interrupt message to the AP11 through the interrupt output port, and after the AP11 receives the interrupt message, it sends an inquiry message to the DSP IC12 through the I2C interface, and then the DSP IC12 reports the failure to the AP11 through the I2C interface.
According to the hearing aid device based on the mobile terminal, provided by the embodiment of the invention, the functions of the hearing aid are integrated in the mobile terminal, so that a user does not need to carry the mobile terminal and the hearing aid at the same time and carry chargers of the two devices, and convenience is provided for the hearing aid user. In addition, because the DSP IC for realizing the hearing aid function is arranged outside the Codec in the embodiment of the invention, after the hearing aid function of the mobile terminal is started, the Codec and the AP of the mobile terminal are both in the energy-saving mode, the power consumption of the mobile terminal can be reduced, and the standby time of the mobile terminal can be prolonged.
The embodiment of the invention also provides a mobile terminal, which comprises the hearing aid device based on the mobile terminal described in the embodiment, the mobile terminal is connected with the audio playing equipment or adopts the audio playing device of the mobile terminal to realize the function of the hearing aid, and when the mobile terminal realizes the function of the hearing aid, the extra consumption power consumption is smaller.
