The intelligent electronic equipment develops to the present level, the requirement on the sound effect of the external sound is higher and higher, and the sound quality and the sound efficiency of the external sound directly influence the experience of a user in the scenes of games, videos, audios and the like; compared with a single loudspeaker design scheme, the two-loudspeaker design scheme has the advantages that the most intuitive feeling is the stereo effect, and besides the increase of the volume, the formation of a stereo sound field also enables a user to have a more immersive feeling.
The traditional circuit system framework diagram of a single speaker is shown in fig. 1, and the functions of the modules of the single speaker framework diagram are as follows:
the central processing unit 11: a control hub for the entire system;
I2S module 13: the central processing unit 11 transmits the audio data to the power amplifier 14 through the I2S module 13; due to the design scheme of the single speaker, at this time, the data transmitted by the I2S module 13 is not divided into left and right channels, but is sent to the power amplifier 14 through the central processing unit 11 after the internal sound mixing processing of the stereo sound source, and finally acts on one speaker 15 to make sound;
two-wire serial bus (I2C) module 12: the central processing unit 11 controls the operation of the power amplifier 14 through the I2C module 12;
the power amplifier 14: for driving the speaker 15;
the speaker 15: and playing the corresponding voice information.
The design scheme of the double loudspeakers needs to carry two power amplifiers for respectively driving the respective loudspeakers; the basic circuit system framework diagram of the current mainstream dual-speaker design is shown in fig. 2, and the functions of the modules of the dual-speaker framework diagram are as follows:
the central processing unit 21: a control hub for the entire system;
I2S module 23: the central processing unit 21 transmits audio data to two power amplifiers through the I2S module 23, the two power amplifiers share one group of I2S modules 23, according to the I2S protocol, the same group of I2S modules 23 respectively transmit left and right channel audio data of a stereo sound source to the two power amplifiers, and finally the audio data is applied to the two speakers to form a stereo sound effect;
I2C module 22: the central processing unit 21 controls the operation of the two power amplifiers through the I2C module 22;
first power amplifier 24: for driving a first speaker 25, i.e. an upper speaker;
second power amplifier 26: for driving a second speaker 27, i.e. a lower speaker;
an upper loudspeaker: the loudspeaker which is arranged at the upper position of the electronic equipment and simultaneously produces sound with the lower loudspeaker to form stereo sound effect;
a lower speaker: the loudspeaker arranged at the lower position of the electronic equipment and the upper loudspeaker can simultaneously produce sound to form stereo sound effect.
By combining the circuit framework and principle analysis, the comparison shows that compared with the traditional single loudspeaker design, the current double-loudspeaker design has the advantages that the voice data of the left and right sound channels of a stereo sound source can be played through the two loudspeakers respectively to form a stereo sound field, so that the sound quality is improved; when the single loudspeaker is designed to play a stereo sound source, the stereo sound source can only be played after internal sound mixing processing, so that the single loudspeaker design can play audio data of the stereo sound source without loss, but cannot form a stereo sound field.
At present, a CPU of a dual-speaker electronic device transmits data of left and right channels to two power amplifiers through an I2S bus to act on an upper speaker and a lower speaker, where one speaker correspondingly plays data of one channel, for example, the upper speaker only plays left channel data, the lower speaker only plays right channel data, and the two speakers work together to form a stereo sound effect.
The following describes in detail a speaker control method, a speaker control device, and an electronic device according to embodiments of the present application with reference to the accompanying drawings.
Specifically, as shown in fig. 2 and fig. 3, an embodiment of the present application provides a speaker control method, which is applied to an electronic device, where the electronic device includes: a first circuit comprising a first speaker 25 and a second circuit comprising a second speaker 27; the method comprises the following steps:
and step 32, under the condition that one of the first impedance value and the second impedance value meets a preset condition, controlling the electronic equipment to be switched from a double-loudspeaker working mode to a single-loudspeaker working mode, wherein in the single-loudspeaker working mode, a circuit where a loudspeaker with an impedance value meeting the preset condition is located is in an off state.
Specifically, when the electronic device is in a dual speaker operating mode, that is, a circuit system frame diagram of the electronic device is shown in fig. 2, the first speaker 25 and the second speaker 27 are both in an operating state, the first speaker 25 may be an upper speaker, the second speaker 27 may be a lower speaker, and the upper speaker and the lower speaker generate sound at the same time to form a stereo sound effect. When the electronic device is switched from the dual-speaker working mode to the single-speaker working mode, that is, the first speaker 25 works, the circuit where the second speaker 27 is located is in an off state; or the second speaker 27 is operated and the circuit in which the first speaker 25 is located is in an open state. When the first impedance value and the second impedance value both satisfy a preset condition, the circuit in which the first speaker 25 is located and the circuit in which the second speaker 27 is located are both in an off state, and at this time, the electronic device is in a fault state.
In the above embodiment of the present application, when the electronic device is in a dual-speaker operating mode, a first impedance value corresponding to the first speaker and a second impedance value corresponding to the second speaker are obtained, and when one of the first impedance value and the second impedance value meets a preset condition, the electronic device is controlled to be switched from the dual-speaker operating mode to a single-speaker operating mode.
Optionally, the preset condition is that the impedance value is greater than a preset threshold value. The main reasons are that: after one of the loudspeakers has failed and is silent, the coil inside the loudspeaker is in an open state, and the corresponding impedance will tend to infinity.
Specifically, if the first impedance value meets a preset condition, that is, the first impedance value is greater than a preset threshold value, it is determined that the first speaker 25 corresponding to the first impedance value is in a failure state, and the first circuit where the first speaker 25 is located is controlled to be disconnected. If the second impedance value meets a preset condition, that is, the second impedance value is greater than a preset threshold value, it is determined that the second speaker 27 corresponding to the second impedance value is in a failure state, a second circuit where the second speaker 27 is located is controlled to be switched off, and after one speaker fails and is silent, a single-speaker output scheme is changed, and meanwhile, the voice data of the two channels can be played to enable a user to sense, so that not only is the voice data not lost, but also the work of the corresponding power amplifier is not required to be continuously maintained, and thus, the power consumption is saved.
Optionally, the step 31 includes:
acquiring a first current value and a first voltage value in the first circuit and a second current value and a second voltage value in the second circuit;
and obtaining a first impedance value corresponding to the first loudspeaker according to the first current value and the first voltage value, and obtaining a second impedance value corresponding to the second loudspeaker according to the second current value and the second voltage value.
Specifically, when the electronic device is in a dual-speaker operating mode, that is, both the first circuit and the second circuit are paths, a first impedance value may be obtained by obtaining a first current value and a first voltage value of the first circuit, and the first impedance value may be used as an impedance value corresponding to the first speaker, so as to determine whether the first speaker fails. The second impedance value can be obtained by obtaining a second current value and a second voltage value of the second circuit, and the second impedance value can be used as an impedance value corresponding to the second speaker, so as to determine whether the second speaker fails.
Optionally, as shown in fig. 2, the first circuit may further include a first power amplifier 24 connected to the first speaker 25, and the second circuit further includes a second power amplifier 26 connected to the second speaker 27; the step 31 may include:
when the electronic device is in an operating state, a first impedance value corresponding to the first speaker 25 is obtained through the first power amplifier 24, and a second impedance value corresponding to the second speaker 27 is obtained through the second power amplifier 26.
Specifically, when the central processing unit 21 determines that one of the speakers fails, the central processing unit 21 turns off the power amplifier corresponding to the failed speaker through the I2C module, and switches to the single speaker operating mode. In general, the normal impedance of the speaker is about 8 ohms, and the speaker failure is silent because a coil inside the speaker is blown out, and after the coil is blown out, a path inside the speaker is equivalent to an open state, so that the impedance of the speaker is increased and even tends to infinity, and therefore, whether the speaker fails or not can be judged by comparing the impedance value of the speaker detected by the power amplifier with a preset threshold value. If the impedance value of the loudspeaker exceeds a preset threshold value, judging that the loudspeaker is invalid; and if the impedance value of the loudspeaker is smaller than a preset threshold value, judging that the loudspeaker is normal. The preset threshold is an impedance threshold for determining whether the speaker corresponding to the impedance value is failed, and can be set as required.
Optionally, the first impedance value is a first current value and a first voltage value in the first circuit, which are obtained by the first power amplifier, and an impedance value is obtained according to the first current value and the first voltage value.
Optionally, the second impedance value is a second current value and a second voltage value in the second circuit, which are obtained by the second power amplifier, and an impedance value is obtained according to the second current value and the second voltage value.
Specifically, as shown in fig. 2, when the first power amplifier 24 and the second power amplifier 26 are in an operating state, both the first circuit and the second circuit are in a pass state, the first power amplifier 24 may detect a first voltage value and a first current value on the first circuit in real time, and the second power amplifier 26 may detect a second voltage value and a second current value on the second circuit in real time. The first power amplifier 24 may obtain a first impedance value according to the first current value and the first voltage value, that is, the first impedance value of the first speaker 25, and feed back the first impedance value to the central processing unit 21 through the I2S module 23, where the central processing unit 21 compares the first impedance value with a preset threshold, and if the first impedance value is greater than the preset threshold, it is determined that the first speaker 25 is disabled. The second power amplifier 26 may obtain a second impedance value according to the second current value and the second voltage value, that is, the second impedance value of the second speaker 27, and feed the second impedance value back to the central processing unit 21 through the I2S module 23, where the central processing unit 21 compares the second impedance value with a preset threshold value, and if the second impedance value is greater than the preset threshold value, it is determined that the second speaker 27 is disabled.
Optionally, the first speaker is configured to play a first channel of audio data, the second speaker is configured to play a second channel of audio data, and after step 32, the method further includes:
acquiring the first channel audio data and the second channel audio data, and merging the first channel audio data and the second channel audio data;
and playing the audio data after the combination processing through a loudspeaker of which the impedance value does not meet the preset condition.
Specifically, as shown in fig. 2, if the central processing unit 21 determines that one of the speakers fails, the central processing unit 21 turns off the power amplifier corresponding to the failed speaker through the I2C module, and switches to the single speaker operating mode. The central processing unit 21 obtains the first channel audio data and the second channel audio data, and merges the first channel audio data and the second channel audio data, that is, the first channel audio data and the second channel audio data are subjected to internal audio mixing processing, and are played through a speaker which is not failed, so that the audio data is ensured not to be lost due to failure of the speaker, and meanwhile, the power consumption can be reduced.
In summary, in the embodiment of the present application, when the electronic device is in the dual-speaker operating mode, acquiring a first impedance value corresponding to the first loudspeaker and a second impedance value corresponding to the second loudspeaker, controlling the electronic device to switch from a dual-speaker operating mode to a single-speaker operating mode when one of the first impedance value and the second impedance value is greater than a preset threshold value, after the electronic device is silent when one of the speakers fails, the single speaker output scheme may be changed, meanwhile, the voice data of the double channels can be played to be perceived by the user, so that the voice data can not be lost, the work of the corresponding power amplifier is not required to be continuously maintained, therefore, the power consumption is saved, the satisfaction degree of a user and the reliability of a product are improved, and the technical feasibility and the mass production are high.
