Referring to fig. 2, fig. 2 is a schematic flow chart of an audio signal playing method according to an embodiment of the present application, where the audio signal playing method is applied to a projector, the projector includes a host, a plurality of bases disposed on the host, and a plurality of speakers corresponding to the number of the bases, and the method includes the following steps.
S201, determining a first base which is closest to a first sound box in the plurality of bases, wherein the first sound box is a sound box in the plurality of sound boxes.
The projector generally comprises a plurality of bases and a plurality of sound boxes corresponding to the bases in number, and if the projector is not used for the first time, the general sound boxes can keep a connection relation with the bases corresponding to the projector in the last use. That is, the sound box and the base can be always connected, or when the device is started, the sound box is automatically connected with the base connected last time again. When the first base closest to the first sound box is determined, the determination can be performed in a contact mode or a wireless mode.
S202, determining whether the first base is matched with the first sound box.
When two bases exist in the projector, the audio signal is usually divided into a left channel audio signal and a right channel audio signal, and the two audio signals are respectively sent to different bases, so that when the bases send respective audio signals to the sound box for playing, it is necessary to determine whether the sound box is matched with the base or not, that is, it is necessary to determine whether the sound box placed on the left base is matched with the left base or not. Because if when the left side base with place the audio amplifier on the base on the right when being connected, the audio amplifier on the base on the right can play left channel audio signal, can cause the acoustic image disorder like this, influence user's listening experience. The time for determining whether the first base is matched with the first sound box may be when the projector is turned off, the sound box is in contact with the base, or when the projector is turned on, it may be determined whether the first base is matched with the first sound box, or when the base determined by the first sound box and closest to the first sound box is changed, it may be determined again whether the base currently closest to the first sound box is matched with the first sound box.
S203, under the condition that the first base is matched with the first sound box, sending an audio signal to the first sound box through the wireless transmitting module of the first base, and playing the audio signal after receiving the audio signal through the wireless receiving module of the first sound box.
If the first base is matched with the first sound box, that is, the first base is connected with the nearest first sound box, or the transmitting frequency and the receiving frequency of the wireless transmitting module of the first base are the same as those of the wireless receiving module of the nearest first sound box, the audio signal can be directly transmitted to the first sound box. If the projector has two bases, the sound box closest to the left base is just connected with the left base at the moment, the left channel audio signal sent by the left base is played, and the right base is the same.
S204, under the condition that the first base is not matched with the first sound box, a communication link between the first base and the first sound box is established, the wireless transmitting module of the first base sends the audio signal to the first sound box through the communication link, and the audio signal is played after the wireless receiving module of the first sound box receives the audio signal.
If the first base is not matched with the first sound box, that is, the first base is not connected with the nearest first sound box, the sound boxes or the bases connected with the first base and the first sound box respectively need to be disconnected, then a communication link between the first base and the first sound box is established, so that the first base is connected with the first sound box, and then the audio signal received by the first base is sent to the first sound box through the wireless transmission module. That is to say, if the projector includes two bases this moment, the left base with place the audio amplifier on the right base and be connected, the right base with place the audio amplifier on the left base and be connected, if do not reestablish the relation of connection between audio amplifier and base this moment, right track audio signal will be broadcast to the audio amplifier on the left, left track audio signal can be broadcast to the audio amplifier on the right, can cause the acoustic image disorder like this, consequently, need reestablish the communication link between audio amplifier and base, make the left base with place the audio amplifier connection on the left base, the base on the same reason right with place the audio amplifier connection on the right base.
It can be seen that, in this application embodiment, first confirm with the nearest first base of first audio amplifier distance in a plurality of bases, first audio amplifier is audio amplifier in a plurality of audio amplifiers, then confirm first base with whether first audio amplifier matches, under the condition that first base with first audio amplifier matches, to first audio amplifier sends first audio signal, and through first audio amplifier broadcast first audio signal, under the condition that first base with first audio amplifier does not match, establish first base with the communication link of first audio amplifier, through communication link to first audio amplifier send first audio signal, and through first broadcast first audio signal. Like this, can the audio signal that present audio amplifier needs to broadcast by automatic identification for the base that will put can be confirmed at will to the audio amplifier, and the sound image can not appear and fix a position the disorderly condition, improves user's use and experiences.
In one possible example, the first speaker includes a first contact, each of the plurality of bases includes a second contact, and the determining a first base of the plurality of bases that is closest to the first speaker includes: and under the condition that the first contact is contacted with the second contact, determining that a base corresponding to the second contact contacted with the first contact is a first base.
Each sound box is provided with a first contact, each base also comprises a second contact, and for the magnetic suspension sound box, when the projector is turned off, the base is not electrified, the sound box can fall into the base, the sound box can be in contact with the base at the moment, and the first sound box closest to the first base can be determined through the second contact on the base and the first contact on the sound box. That is, when determining the sound box closest to the first base, the sound box corresponding to the first contact contacted by the second contact of the first base may be determined as the first sound box. This embodiment is when audio amplifier and base contact, confirms first audio amplifier through first contact and second contact, and in other modes, can also confirm the first base that is nearest with first audio amplifier distance through other induction system when first base contacts with the audio amplifier.
Therefore, in the embodiment, when the sound box is in contact with the base, the first base which is closest to the first sound box is determined according to the contact relation, so that the distance relation between the base and the sound box can be conveniently and quickly determined.
In one possible example, the first speaker includes a sensor, each of the plurality of pedestals includes a signal emitter, and the determining a first pedestal of the plurality of pedestals that is closest to the first speaker includes: receiving an identity recognition signal sent by the signal transmitter according to the sensor; determining a signal strength of the identification signal; and when the signal intensity is greater than a preset value, determining that a base corresponding to a signal transmitter sending the identification signal is a first base.
Each sound box comprises a sensor, each base is provided with a signal emitter corresponding to the sensor, the signals are identification signals of the bases, and the identification signals are used for the first sound box to determine the first base which is closest to the first sound box in the plurality of bases. In a similar way, the sensor can be positioned on the base, meanwhile, the signal emitter corresponding to the sensor is positioned on the first sound box, and the base for receiving the signal with the signal intensity larger than the preset value is determined to be the first base. The receiving of the signal transmitted by the signal transmitter according to the sensor comprises: and the signal emitter emits signals once every other preset time, and the sensor synchronously receives the signals emitted by the signal emitter. Or the signal emitter always emits the signal, and the sensor receives the signal once every preset time. Even if a plurality of bases exist, due to the limited shape of the bases, only the sensor vertically positioned above the base can receive the signal transmitted by the signal transmitter of the base, so that the base corresponding to the signal transmitter transmitting the identity signal can be determined to be the first base as long as the intensity of the identity signal received by the sensor on the sound box is greater than the preset value. Because the projector can simultaneously comprise a plurality of bases, the sensor of the sound box can receive signals transmitted by different signal transmitters, when one sensor receives a plurality of signals, the signal intensity of all the signals received at the current time can be calculated, and the signal transmitter with the maximum transmitted signal intensity is determined, and the base corresponding to the signal transmitter is the first base.
In the concrete realization, because the projector includes a plurality of audio amplifiers and a plurality of bases the same with a plurality of audio amplifiers quantity, consequently if the projector includes two audio amplifiers and two bases, and first audio amplifier and second audio amplifier in these two audio amplifiers determine that the base nearest rather than the distance is first base, confirm this moment and include with first base distance nearest audio amplifier: respectively determining the distances S between the first sound box and the first base and between the first sound box and the second base according to the signal strength of the signal received by the first sound box1 left sideAnd S1 right sideWherein the first base is located on the left side of the projector, and the second base is located on the right side of the projector; respectively determining the distances S between the second sound box and the first base and the second base according to the signal intensity of the signal received by the second sound box2 left sideAnd S2 right side(ii) a According to S1 left side、S1 right side、 S2 left sideAnd S2 right sideAnd determining the sound box closest to the first base. Determination of S1＝S1 left side-S1 right side，S2＝S2 left side-S2 right sideIf S is1>0，S2<0, determining that the first sound box is closest to the first base on the left side, and the second sound box is closest to the second base on the right side; if S1<0，S2>0, determining that the first sound box is closest to the second base on the right side, and the second sound box is closest to the first base on the left side; if S1<0， S2<0, or S1>0，S2>And 0, respectively determining the base corresponding to the signal with the maximum intensity obtained by the first sound box and the second sound box as the base closest to the first sound box and the second sound box. When the signal emitter is a luminous source and the sensor is a photoelectric sensor, the distance between the sound box and the base can be adjustedThe calculation is carried out by S-c-t, wherein c is the speed of the light propagating in the air, and t is the time from the signal emitter to the sensor.
Therefore, in the embodiment, the first base closest to the first sound box in the plurality of bases is determined according to the identity recognition signal transmitted by the base, so that the first base closest to the first sound box can be conveniently and quickly selected.
In one possible example, the determining whether the first base and the first speaker are matched comprises: acquiring the receiving frequency of a wireless receiving module of the first sound box and the transmitting frequency of a wireless transmitting module of the first base; determining that the first pedestal is matched with the first loudspeaker box under the condition that the transmitting frequency is the same as the receiving frequency; determining that the first base does not match the first speaker if the transmit frequency is different from the receive frequency.
Wherein, each base has a wireless transmitting module, the transmitting frequency of each wireless transmitting module can be different, but the receiving frequency of the wireless receiving module in the first sound box matched with the base is the same as the transmitting frequency of the base. The determining whether the first base is matched with the first speaker may further include: acquiring first identification information of the first base; determining second identification information prestored in the first sound box, wherein the second identification information is identification information of a base which establishes a connection relation with the first sound box for the last time; if the first identification information is the same as the second identification information, determining that the first base is matched with the first sound box; and if the first identification information is different from the second identification information, determining that the first base is not matched with the first loudspeaker box.
Each base has unique identification information, the identification information can determine the identity of the base, and the identification information can be a number or a name set by a user. When the sound box determines the base closest to the sound box, the sound box reads the identification information of the base, the identification information is stored in the database after the connection between the sound box and the base is established, and the identification information in the database can be deleted after the sound box is disconnected from the base. That is, when the speaker determines the base closest to the speaker, the speaker reads the identification information of the base, and if the identification information of the base is the same as the identification information in the speaker database, the speaker and the base are matched. And if the identification information of the base is different from the identification information in the sound box database, determining that the base is not matched with the sound box. After determining that the first base does not match the first speaker, the method further comprises: disconnecting the current communication link of the first sound box, and deleting the identification information in the database of the first sound box; establishing a communication link between the first base and the first loudspeaker box; and storing the identification information of the first base in a database of the first sound box.
Therefore, in the embodiment, whether the first sound box is matched with the first base or not is determined according to the transmitting frequency of the wireless transmitting module and the receiving frequency of the wireless receiving module, so that the matching is not only accurate and convenient, but also the matching can be rapidly determined, and the user experience is improved.
In one possible example, the sensor comprises a photoelectric sensor or a magneto-sensitive sensor.
The type of the photoelectric sensor may be any, such as an optical coupler sensor or an infrared sensor, and the type of the sensor corresponds to the type of the signal emitter. When the sensor is a photoelectric sensor, the signal emitter on the base can be a gas discharge lamp, a light emitting diode or a laser, and when the sensor is a magnetic-sensitive sensor, the projector comprises a magnetic suspension sound box, so that a magnetic field can be generated after the base is electrified, and the magnetic field can be determined as the corresponding signal emitter. Of course, the type of the sensor may also include other types such as an inductive sensor, a resistive sensor, etc., as long as the distance between the sound box and the base can be determined according to the signal intensity.
Therefore, in the embodiment, signals emitted by different bases can be obtained according to the sensor, and the distance between the sound box and the base can be determined according to the signal intensity, so that the first base closest to the first sound box can be conveniently and quickly selected.
In a possible example, each of the bases includes the wireless transmitting module, each of the sound boxes includes the wireless receiving module, a transmitting frequency of each of the wireless transmitting modules is different, and a receiving frequency of each of the wireless receiving modules is different.
The wireless transmitting modules and the wireless receiving modules corresponding to the multiple bases and the multiple sound boxes respectively can be distinguished by different receiving and transmitting frequencies, so that the situation that the multiple sound boxes are in non-differentiated mixed same-frequency connection before the first base closest to the first sound box is determined according to the identity identification signal is avoided. The specific wireless transceiver module is not particularly required here, as long as wireless transmission and reception of audio can be achieved.
Therefore, in the embodiment, the plurality of wireless transmitting modules and the plurality of wireless receiving modules respectively correspond to different receiving and transmitting frequencies, so that the condition that the plurality of sound boxes are not distinguished and are connected in a mixed same frequency mode can be prevented, and the connection accuracy of the sound boxes and the base is improved.
In one possible example, after the establishing the communication link between the first base and the first speaker, the method further comprises: and adjusting the receiving frequency of the wireless receiving module of the first sound box, so that the receiving frequency of the wireless receiving module of the first sound box is the same as the transmitting frequency of the wireless transmitting module of the first base.
The plurality of sound boxes corresponding to the bases are respectively provided with a wireless receiving module, the working receiving wireless frequency of the module can be changed along with the identity recognition signal received by the sensor, and finally the working receiving wireless frequency is changed into a new frequency which is the same as the transmitting frequency of one corresponding base, and is shown as a matched first base and a first sound box. That is, the plurality of bases adopt different wireless transmission frequencies, and the plurality of sound boxes can respectively change the wireless receiving frequency according to the identification signals received by the sensor and are matched with the same transmitting and receiving frequency of the identified base.
In one possible example, before the establishing the communication link between the first base and the first speaker, the method further includes: determining whether the first chassis has established a communication link with a second loudspeaker, the second loudspeaker being a loudspeaker of the plurality of loudspeakers other than the first loudspeaker; if yes, determining whether to establish a communication link between the first base and the first sound box according to the working state of the second sound box, wherein the working state comprises that a first audio signal is being played or a first audio signal is not played currently; under the condition that the working state is that a first audio signal is being played, playing first prompt information according to the first sound box, wherein the first prompt information is used for prompting a user that the first audio is played; after the first sound box plays the prompt message, determining whether the first sound box needs to be forcibly connected with the first base according to user selection; and if so, disconnecting the communication link between the first base and the second sound box.
The projector comprises a plurality of sound boxes and a plurality of bases corresponding to the number of the sound boxes, so that before the first sound box determines that the first base is the base closest to the first sound box, the first base is already connected with other sound boxes, whether an audio signal of the first base is played by other sound boxes needs to be determined first, if the audio signal is played, a prompt tone needs to be sent through the sound boxes to prompt a user that the closest base plays audio, whether the first sound box needs to be connected with the first base is determined, if the audio signal is played, a current communication link of the first base is disconnected, and a communication link between the first base and the first sound box is established. If the current audio signal of the first base is not played, the current communication link of the first base can be directly disconnected, and a communication link between the first base and the first loudspeaker box is established.
Therefore, in this example, whether to continue establishing the communication link between the first base and the first sound box is determined according to the playing condition of the audio signal of the current base, so that not only can time be saved, the connection times be reduced, but also the user requirements can be met.
