Detailed Description
Fig. 1 exemplarily shows a schematic structural diagram of a terminal device applicable to the embodiment of the present application, and as shown in fig. 1, the terminal device includes a main Chip (SoC) 101. The main chip 101 may be connected to one or more power amplifier chips. When there are multiple power amplifier chips, a master power amplifier chip and a slave power amplifier chip may be provided, for example, the master chip 101 shown in fig. 1 is connected to the master power amplifier chip 102, and the 1 st slave power amplifier chip 103 …, the (N-1) th slave power amplifier chip 104, respectively.
Each power amplifier chip can be connected with a group of loudspeakers, and each group of loudspeakers respectively comprises a left sound channel loudspeaker and a right sound channel loudspeaker. For example, the main power amplifier chip 102 shown in fig. 1 is connected to the group 1 speaker 105, and the group 1 speaker 105 includes two speakers, i.e., a left channel speaker 108 and a right channel speaker 109. For another example, the 1 st slave power amplifier chip 103 shown in fig. 1 is connected to the 2 nd group of speakers 106, and the 2 nd group of speakers 106 includes two speakers, which are a left channel speaker 110 and a right channel speaker 111. For example, the (N-1) th slave power amplifier chip 104 shown in fig. 1 is connected to the nth set of speakers 107, and the nth set of speakers 107 includes two speakers, namely, a left channel speaker 112 and a right channel speaker 113.
The main chip 101 in fig. 1 may receive an audio source, perform certain processing (such as surround sound effect) on the received audio source, send an external audio source to a left channel speaker connected to each power amplifier chip through a left channel audio stream 114, and send the external audio source to a right channel speaker connected to each power amplifier chip through a right channel audio stream 115. Each power amplifier chip can perform digital-to-analog conversion on the received audio source and then send the audio source to each group of loudspeakers so that the loudspeakers play the received audio source. Each power amplifier chip can determine attribute information of a loudspeaker group connected with the power amplifier chip by adopting a mode of configuring a corresponding register, such as a sound production frequency band, a sound amplification factor and the like of the loudspeaker.
Fig. 1 only illustrates a schematic diagram of a possible structure of the terminal device in the embodiment of the present application, but the terminal device in the embodiment of the present application may also have other structures, such as a group of speakers existing in the terminal device, where the group of speakers includes only one speaker.
In a particular implementation, a segment of an audio source may include a high frequency signal, an intermediate frequency signal, and a low frequency signal. For example, one possible division is to refer to signals with frequencies greater than 9kHz as high-frequency signals, signals with frequencies between 9kHz, 1.5kHz, and 9kHz to 1.5kHz as intermediate-frequency signals, and signals with frequencies below 1.5kHz as low-frequency signals. Other divisions may exist in implementations.
A plurality of groups of loudspeakers included in one terminal device can be mutually matched for use and are used for respectively playing signals of different frequency bands, so that a better sound effect is provided for a user. For example, group 1 speakers in fig. 1 may be configured as a mid-to-high speaker group, in which case group 1 speakers are used to play the mid-to-high portion of the audio source, group 2 speakers are used to play the mid-to-low portion of the audio source, group 3 speakers are used to play the subwoofer portion of the audio source, and so on.
For example, the group 1 speakers are designed to play signals above 9kHz (kilohertz), that is, the sound emission band of the left channel speaker in the group 1 speakers is above 9kHz, and the sound emission band of the right channel speaker in the group 1 speakers is above 9kHz, in which case the group 1 speakers do not emit sound when receiving signals below 9 kHz.
The terminal device in the embodiment of the application can be a device with multiple groups of speakers, such as a television, a mobile phone, an ipad, a computer and a tablet computer.
In the embodiment of the present application, a group of speakers may be referred to as a speaker group, that is, two terms, a group of speakers and a speaker group, are equivalent and may be used interchangeably.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.
Based on the above, fig. 2 exemplarily illustrates a speaker detection method provided by an embodiment of the present application, and as shown in fig. 2, the method includes:
And, step 202 and step 203 are executed for each set of speakers determined as the set of speakers to be tested.
In the embodiment of the application, the audio source for detection is an audio source used for detection, and the audio source may be an audio source preset in a storage medium of the terminal device, so that it is not necessary to additionally access other signal sources in the process of detecting by playing the audio source for detection, thereby reducing operation steps and improving detection efficiency. The audio source for detection may also be an audio source that performs a certain processing on the audio signal source of the television, for example, the audio source for detection may be an audio source that increases the amplitude of the audio signal source of the television to above the second amplitude threshold.
and step 204, the terminal equipment plays the audio source for detection through the loudspeaker group to be detected.
There is no sequence between step 202 and step 203, and there is no sequence between step 203 and step 204, for example, step 204 may be executed first, and then step 203 may be executed.
As can be seen from fig. 1, in step 204, the terminal device sends the detection audio source to each of the N groups of speakers, controls the speaker group to be detected to be in the non-mute state, and controls other speaker groups except the speaker group to be detected to be in the mute state, so that although other speaker groups also receive the detection audio source corresponding to the speaker group to be detected, because they are in the mute state, they do not make a sound, and therefore do not interfere with the detection of the user, and therefore the occurrence of a misjudgment situation can be avoided, and thus the user can more accurately determine the speaker that has a fault. Furthermore, the embodiment of the application is suitable for the user to carry out preliminary detection on the working state of the loudspeaker when the terminal equipment is abnormal, and the after-sale maintenance efficiency of products can be improved. Furthermore, the embodiment of the application is also suitable for daily self-checking of the user on the sound system, and the experience of the user on the high-quality sound effect can be improved.
In the embodiment of the present application, optionally, each of the N sets of speakers includes a left channel speaker and a right channel speaker. In step 204, the left channel speaker and the right channel speaker in the set of speakers may be further detected separately. Specifically, optionally, if a first channel speaker of the speaker group to be detected needs to be detected, sending an audio source for detection to the first channel speaker of each of the N groups of speakers; and:
disabling transmission of the audio source to the second channel speaker of each of the N sets of speakers; or adjusting the amplitude of the audio source for detection to be below a first amplitude threshold value, and sending the audio source for detection, the amplitude of which is adjusted to be below the first amplitude threshold value, to the second channel loudspeaker of each group of loudspeakers in the N groups of loudspeakers; the first amplitude threshold is not greater than the second amplitude threshold;
if the first sound channel loudspeaker is a left sound channel loudspeaker, the second sound channel loudspeaker is a right sound channel loudspeaker; if the first channel speaker is a right channel speaker, the second channel speaker is a left channel speaker.
Explaining in combination with the above fig. 1, according to the above scheme, when the left channel speaker of the speaker group to be detected is operated, the audio source can be prohibited from being sent to the right channel speaker of each group of speakers in the N groups of speakers, so that the right channel speaker of the speaker group to be detected does not make a sound, and thus the interference caused by the detection process of the left channel speaker of the speaker group to be detected can be avoided.
Or, when the left channel speaker of the speaker group to be detected is processed, the audio source for detection whose amplitude is adjusted to be smaller than the first amplitude threshold value can be sent to the right channel speaker of each group of speakers in the N groups of speakers, and the sound emitted by the right channel speaker of the speaker group to be detected is small, so that the interference caused by the detection process of the left channel speaker of the speaker group to be detected can be avoided. When the right channel speaker of the speaker to be detected is operated, the process is the same as the above, and is not repeated.
In specific implementation, the embodiment of the application can be applied to user self-checking. Before the step 201, in an optional implementation manner, a user may enable the terminal device to enter a self-test process of the speaker through interaction with the terminal device.
Before entering the loudspeaker self-test flow, all loudspeaker groups in the terminal equipment are in a non-mute (un-mute) state. The fact that the group of loudspeakers mentioned in the embodiment of the application are in the mute state means that the group of loudspeakers do not make sound when receiving signals belonging to the sounding frequency band of the group of loudspeakers, and the fact that the group of loudspeakers mentioned in the embodiment of the application are in the non-mute state means that the group of loudspeakers make sound when receiving signals belonging to the sounding frequency band of the group of loudspeakers. If the terminal device is a television, the user may control the television through a remote controller, a mobile phone, an ipad, a tablet computer, and the like.
In an alternative embodiment, the user makes a selection of an operation command on the screen of the terminal device through the remote controller (e.g., selects a "speaker self-test" button on the user interface). Or the user enters the corresponding operation interface by pressing a certain designated key of the remote controller, for example, a button may be preset on the remote controller, and the terminal device enters the "speaker self-check" process when the user presses the button, optionally, prompt information of the button of the remote controller and the corresponding operation interface may be given on the user interface, for example, a prompt "press an OK key on the remote controller to enter the" speaker self-check "process is prompted on the user interface. And if the user selects to enter the loudspeaker self-checking process. After entering the speaker self-checking process, the user interface of the terminal device may give a prompt, such as a prompt "detect the main power amplifier chip-left channel speaker", and play the audio source for detection corresponding to the speaker connected to the "main power amplifier chip", while other players are in a mute state. Alternatively, since only the left channel is detected in this case, the right channel audio stream may be disabled by the main chip or the amplitude of the right channel audio stream may be reduced below the first amplitude threshold so that the "main power chip-right channel speaker" does not emit sound or emits a smaller sound to avoid interfering with the user's detection process of the "main power chip-left channel speaker".
Further, after the detection of "main power amplifier chip-left channel speaker" is finished, the user interface of the terminal device may prompt the client to "whether to hear the big and clear sound of main power amplifier chip-left channel speaker? ". The customer may continue to select the "self-test" button to test for the next speaker (e.g., "main power amplifier chip-right channel speaker") based on the test results. The detection process may also be exited immediately upon selection of the "end" button due to an anomaly. Or after the N groups of speakers are completely detected, an end button can be selected to immediately quit the detection process, and a self-detection button is continuously triggered to perform the cycle detection on the N groups of speakers again. The scheme provided by the embodiment of the application can adopt a self-checking button on a user interface or a remote controller test key as a trigger mechanism, trigger and detect circularly for multiple times, is convenient for a user to operate, and can save resources due to the simple operation process.
The sorting relation of the N groups of loudspeakers can be prestored in the terminal equipment, or the user can select the loudspeaker group which needs to be detected currently.
Before the step 201, in an optional implementation manner, after the terminal device enters the self-test procedure, a sound effect, such as surround sound (surround), may be turned off. These effects may cause crosstalk problems in the left and right channels, and thus turning off the effects may further improve the detection effect. For example, the sound effect function on the main chip 101 may be turned off as described with reference to fig. 1.
In step 202, the audio source that satisfies that the time length of the signal belonging to the sounding frequency band of the speaker to be detected is greater than the time length threshold is an audio source that satisfies any one of the following conditions:
frequency sweeping;
audio sources with the total duration of signals belonging to the sounding frequency band being greater than the duration threshold;
audio sources of which the duration of a continuous section of signals belonging to the sounding frequency band is greater than a duration threshold;
the audio source is characterized in that the total duration of signals belonging to the sounding frequency band is greater than a duration threshold, and the ratio of the signals belonging to the sounding frequency band of the loudspeaker group to be detected is greater than a ratio threshold;
and the audio source is characterized in that the duration of a continuous section of signals belonging to the sounding frequency band is greater than a duration threshold, and the occupation ratio of the signals belonging to the sounding frequency band of the loudspeaker group to be detected is greater than an occupation ratio threshold.
In the step 202, in an optional implementation manner, the detection audio source corresponding to the speaker group to be detected may be determined according to a preset association relationship, for example, the detection audio source corresponding to each group of speakers may be preset, for example, the association relationship between the speakers determined as the speaker group to be detected and the sweep tone may be preset, and the detection audio source corresponding to the speaker group is the sweep tone.
In another optional embodiment, the audio source for detection corresponding to the group of speakers to be detected may also be determined according to the attribute information of the group of speakers to be detected.
The attribute information of the to-be-detected loudspeaker group may include the sound emission frequency band of the loudspeaker group, for example, when a group of loudspeakers is determined to be the to-be-detected loudspeaker group, an audio source, in which the proportion of the signal belonging to the sound emission frequency band of the to-be-detected loudspeaker group is greater than the proportion threshold, may be used as the detection audio source of the to-be-detected loudspeaker group. For example, the occupancy threshold may be set to 60%, and the occupancy of the signals belonging to the sounding frequency band in the audio source for detection for 60 seconds is greater than 60%, such as 100% (i.e., all the signals belonging to the sounding frequency band for 60 seconds of the audio source for detection), 70% (i.e., 70% of the signals belonging to the sounding frequency band for 60 seconds of the audio source for detection), and so on.
For another example, if the attribute information of the to-be-detected speaker group includes the sound emission frequency band of the speaker group, the audio source whose total duration of the signal belonging to the sound emission frequency band is greater than the duration threshold may be used as the detection audio source of the to-be-detected speaker group. For example, the duration threshold may be set to 90 seconds, and a detection audio source with a duration of 2 minutes may be continuous or discontinuous for all signals belonging to the sounding frequency band, but the total duration of the signals belonging to the sounding frequency band in the detection audio source needs to be greater than 90 seconds, such as 100 seconds, 120 seconds, and the like.
For another example, if the attribute information of the to-be-detected speaker group includes the sound emission frequency band of the speaker group, the audio source with the duration of the continuous signal segment belonging to the sound emission frequency band being greater than the duration threshold may be used as the detection audio source of the to-be-detected speaker group. For example, the duration threshold may be set to 70 seconds, for example, a detection audio source with a duration of 2 minutes, in which there exists a continuous signal belonging to the sounding frequency band, and the duration of the continuous signal is greater than 70 seconds, for example, 80 seconds, 120 seconds, and so on.
The above-mentioned condition of waiting to detect the audio source for detection that loudspeaker set corresponds can make up the use, for example, if the attribute information that detects loudspeaker set includes the vocal frequency range of this loudspeaker set, then can be greater than the total duration of the signal that belongs to the vocal frequency range long enough for time threshold value, and belong to the audio source that accounts for more than the ratio threshold value of the signal of the vocal frequency range of waiting to detect loudspeaker set as this audio source for detection that detects loudspeaker set. For another example, if the attribute information of the to-be-detected speaker group includes the sound emission frequency band of the speaker group, an audio source, which can belong to a continuous section of the sound emission frequency band and has a duration greater than the duration threshold and a ratio of the signal belonging to the sound emission frequency band of the to-be-detected speaker group greater than the ratio threshold, is used as the detection audio source of the to-be-detected speaker group. Other combinations are not illustrated.
In a specific implementation, the detection audio source can be flexibly selected for each group of speakers, and in an optional implementation, two detection audio sources corresponding to any two groups of speakers in the N groups of speakers are the same.
For example, the sweep frequency sound is used as the audio source for detection corresponding to each group of speakers in all speakers. Therefore, as the sweep frequency sound comprises all frequency bands, when each group of loudspeakers is detected, a user can hear the sound with longer time, and then the loudspeakers can be judged according to the heard sound.
For another example, a section of pre-configured audio sources covering all sound emission frequency bands of the N groups of speakers is used as the audio source for detection corresponding to each group of speakers in all speakers, and the amplitude value of the audio source is greater than the second amplitude threshold. In this way, since the amplitude value of the audio source for detection is increased, even if the proportion of the signal belonging to the sound emission band of the speaker group to be detected is small, the user can hear the sound with a large volume, so that the speaker can be evaluated according to the heard sound.
For another example, the audio source of the television signal that is subjected to a certain operation (for example, increasing the amplitude of the audio source of the television signal to be higher than the second amplitude threshold) is used as the detection audio source corresponding to each set of speakers in all sets of speakers. Therefore, the audio source for detection does not need to be configured, so that the occupation of the storage space is reduced, and because the amplitude value of the audio source for detection is increased, even if the occupation ratio of the signal of the sound production frequency band of the speaker group to be detected is less, the user can also hear the sound with larger volume, so that the speaker can be judged according to the heard sound.
In another alternative embodiment, there are at least two groups of speakers in the N groups of speakers, and the two detection audio sources corresponding to the two groups of speakers are different. For example, configuring the detection audio source for each group of speakers according to the sound emission frequency band of each group of speakers, such as for each speaker group serving as the speaker group to be detected in the above content, using the audio source, which belongs to the sound emission frequency band and has a duration of a continuous segment of the signal greater than a duration threshold, as the detection audio source corresponding to the speaker group to be detected. Therefore, the audio sources for detection which are more matched with the sounding frequency bands of the group of loudspeakers can be respectively configured for each group of loudspeakers, and therefore a user can judge each group of loudspeakers more accurately.
Based on the same concept, fig. 3 exemplarily shows a schematic structural diagram of a terminal device provided in an embodiment of the present application, and as shown in fig. 3, a terminal device 300 may be used to execute any of the schemes shown in fig. 2.
