Description
Technical Field
The present application relates to the technical field of audio playback devices, and in particular, to an audio playback control circuit, an audio playback method, an electronic device, and a readable storage medium.
Background
The telephone receiver and the loudspeaker are indispensable parts in the intelligent mobile phone, and a user can talk through the telephone receiver and the loudspeaker, listen to songs and watch videos and the like.
At present, mobile terminals with stereo dual speaker design are increasingly popular, and compared with a single speaker, the dual speaker has a stereo sound field, so that user experience and product satisfaction can be greatly improved. The two-speaker solution usually uses a two-in-one speaker, i.e. the device can be used as a receiver and also as a speaker. However, compared with the common receiver with the size of 1206 (length 12mm and width 6mm) or 0809 (length 8mm and width 9mm), the size of the two-in-one speaker is much larger because the two-in-one speaker has the functions of the speaker and the receiver, for example, the common size is 1210 (length 12mm and width 10mm) or 1310 (length 13mm and width 10mm), and the like. That is, the loop area of the coil of the two-in-one speaker is much larger than that of the coil of the common receiver. In the process of circuit design, because of the existence of electromagnetic effect, if no special requirement exists, a loop is avoided as much as possible in the design process of a circuit PCB (printed circuit board), otherwise the electromagnetic effect is likely to generate interference; especially in the application of products with high integration level of the smart phone, a plurality of interference signals exist among the PCB boards; the changing electrical signal generates a magnetic field, which generates an electrical field through the circuit loop, eventually forming an interference signal.
Fig. 1 shows a schematic position diagram of a receiver 110 ' and a PCB 300 ' in a related art smart phone, where the receiver 110 ' or a two-in-one speaker is located in a position close to the PCB 300 ' in the design of the smart terminal, so that a coil loop of the receiver 110 ' or the two-in-one speaker itself is also very likely to introduce interference, such as Time Division Duplex (TDD) interference of radio frequency. Fig. 2 and 3 show TDD interference situations of the receiver 110' (0809 size) and the two-in-one speaker (1210 size) in the same whole radio frequency environment in the related art. Through the test result, the comparison and discovery that the amplitude of the interference noise electric signal of the common receiver with the size of 0809 is only half of that of the two-in-one loudspeaker with the size of 1210, and the interference of the TDDnoise (time division distortion noise) is in a low frequency band, so that the interference noise cannot be filtered out through magnetic beads or capacitors.
Therefore, although the two-in-one speaker in the related art can achieve the effect of the dual speakers under the condition of reducing the volume of the terminal, the larger size of the two-in-one speaker leads to a larger loop area, and interference is more easily introduced, and low-frequency current sound interference cannot be filtered by traditional means such as capacitance or magnetic beads, so that the problem of receiver downlink current sound is caused when a GSM (global system for mobile communications) network of the intelligent terminal is in call, and user experience and satisfaction are affected.

Specifically, as shown in fig. 1, the audio playing module in the related art includes an earphone 110 ' and a PCB 300 ', where the earphone 110 ' and the PCB 300 ' are disposed at a close position, so that the coil loops of the earphone and the two-in-one speaker unit generate interference (e.g., TDD interference of radio frequency) to the earphone 110 '.

Moreover, the resistance of the resistor 160 can be adjusted, and the effect of reducing the interference noise can be adjusted, so as to meet the user requirement. In addition, the resistor 160 has a simple structure and low cost, thereby being beneficial to reducing the production cost of the audio playing control circuit.

Compared with the conventional circuit design scheme of the dual-speaker as shown in fig. 4, the two-in-one speaker is driven by one smart power amplifier no matter in the speaker mode or the receiver mode, that is, the two-in-one speaker works in the speaker mode and the receiver mode to share a circuit path, and because the external amplification mode is considered, a resistor cannot be serially connected to the shared path of the two-in-one speaker. Specifically, as shown in fig. 4, the audio playing module in the related art includes a receiver 110 ', a second speaker module 120 ', a first driving circuit 130 ', a third driving circuit 150 ', a first driving module 170 ', a third driving module 190 ', and a CPU220 '. The CPU220 'controls the first driving module 170' to be connected to the receiver 110 'through the first driving circuit 130', and the CPU220 'controls the third driving module 190' to be connected to the second speaker module 120 'through the third driving circuit 150'.

In addition, in different working modes, different driving modules are used to drive the first audio playing module 110 to work, which is beneficial to simplifying the control program.
In a specific application, the first driving module 170 and the second driving module 180 are both power amplification modules. Or, the first driving module 170 is a codec (codec), and the second driving module 180 is a power amplifier module. For example, the intelligent power amplifier module may monitor the output voltage and current in real time through an I/V sensor (current sensor/voltage sensor) compared to a general power amplifier module, and then calculate an impedance value to determine the temperature and amplitude of the coil of the first audio playing module 110 at this time, and then dynamically adjust the magnitude of the output power according to the value, so as to improve the output power of the first audio playing module 110 as much as possible on the basis of protecting the first audio playing module 110.
As a possible implementation, as shown in fig. 6 and 8, the audio playback control circuit further includes: a switching part 210 connected in parallel with the noise suppression module, the switching part being capable of being opened or closed to turn on or short-circuit the noise suppression module; when the first audio playing module 110 is in the receiver mode, the switch is turned off to connect the noise suppressing module and the first audio playing module 110; when the first audio playback module 110 is in the speaker mode, the switching member is closed to short-circuit the noise suppression module.
In this embodiment, another scheme for reducing the interference noise on the first audio playing module 110 is designed. The audio playing control circuit further includes a switch element 210, and the noise suppression module is turned on or shorted by the switching state of the switch element 210. Specifically, when the first audio playing module 110 is in the receiver mode, the switch element 210 is turned off, so that the first driving module can drive the first audio playing module 110 to work, and the current sound level of the first audio playing module 110 is reduced through the noise suppression module; when the first audio playing module 110 is in the speaker mode, the switch 210 is closed, and the noise suppression module is short-circuited, so that the first driving module 170 drives the first audio playing module 110 to work, and the noise suppression module does not work at this time, so that the play-out effect of the audio playing control circuit is not affected in the speaker mode. By setting the switch element 210, the noise reduction effect of the audio playing control circuit in the receiver mode and the play-out effect in the speaker mode can be realized only by controlling the on-off state of the switch element 210, and the control is convenient. And a plurality of driving modules are not required to be designed, and the driving of the first audio playing module 110 under different working modes can be realized by only one driving module, so that the number of the driving modules is reduced, thereby being beneficial to reducing the production cost of the audio playing control circuit and being beneficial to reducing the occupied space of the audio playing control circuit.
In specific application, the first driving module is a power amplifier module. Such as a smart power amplifier module.

Compared with the traditional circuit design scheme of the double loudspeakers, as shown in fig. 4, the two-in-one loudspeaker is driven by one intelligent power amplifier no matter in the loudspeaker mode or the receiver mode, that is, the two-in-one loudspeaker works in the loudspeaker mode and the receiver mode to share a circuit path, and because the external amplification mode is considered, compared with the common path of the two-in-one loudspeaker in which series resistance cannot be connected, the noise reduction of the first audio playing module in the receiver mode can be realized while the external amplification mode is considered, the current sound level formed after the first audio playing module is interfered by radio frequency electromagnetic waves is reduced, and therefore the use experience and satisfaction of a user are improved. In addition, under different working modes, different driving modules are adopted to drive the first audio playing module to work, and the simplification of a control program is facilitated.
In a specific application, as shown in fig. 11, a step 1022 of determining whether the first audio playing module needs to enter the first speaker mode is further included. Specifically, step 1024 is executed in case that the first audio playing module does not need to enter the first speaker module, and step 1026 is executed in case that the first audio playing module needs to enter the speaker module.
