The housing 20 may also be used to mount functional modules of the terminal 100, such as a display device, an imaging device, a power supply device, and a communication device, so that the housing 20 provides protection for the functional modules, such as dust prevention, drop prevention, and water prevention.
The audio playback device 10 includes a housing 11, two first speakers 12, one second speaker 13, a battery 14, and a circuit board 15. Both the first speaker 12 and the second speaker 13 are disposed within the housing 11.
The housing 11 may be a part of the casing 20, for example, the housing 11 includes a plurality of sub-housings (e.g., 3) fixedly mounted on the casing 20 (or integrally formed with the casing 20), and the two first speakers 12 and the second speakers 13 are respectively disposed in the 3 sub-housings to isolate the speakers from other functional components in the terminal 100, so as to prevent audio vibration of the speakers from affecting the other functional components. Alternatively, the housing 11 is a casing 20, and the two first speakers 12 and the two second speakers 13 are both disposed in the housing 11, i.e., the two first speakers 12 and the two second speakers 13 are both disposed in the casing 20. In the embodiment of the present application, the housing 11 is a casing 20.
The housing 11 includes a top wall 111, a bottom wall 112, side walls 113, a front face 114, and a back face 115. The top wall 111 is opposite the bottom wall 112, the front face 114 is opposite the back face 115, the side wall 113 connects the top wall 111 and the bottom wall 112, and the top wall 111, the bottom wall 112 and the side wall 113 connect the front face 114 and the back face 115. The top wall 111, the bottom wall 112, the side wall 113, the front surface 114 and the back surface 115 enclose an accommodating space 116, and the two first speakers 12, the two second speakers 13, the battery 14 and the circuit board 15 are all disposed in the accommodating space 116.
The top wall 111 and the bottom wall 112 are both provided with a first sound outlet hole 117, and the side wall 113 is provided with a second sound outlet hole 118, so that the audio output by the two first speakers 12 and the second speakers 13 arranged in the housing 11 respectively goes out from the first sound outlet hole 117 and the second sound outlet hole 118, thereby realizing the stereo output when the terminal 100 displays a horizontal screen; in another embodiment, the two opposite side walls 113 are opened with a first sound outlet hole 117, and the bottom wall 112 is opened with a second sound outlet hole 118, so that the audio output by the two first speakers 12 and the second speaker 13 disposed in the housing 11 respectively goes out from the first sound outlet hole 117 and the second sound outlet hole 118, thereby realizing stereo output when the terminal 100 is used for vertical screen display; in another embodiment, the top wall 111 and the bottom wall 112 are both opened with a first sound outlet 117, and the back surface 115 is opened with a second sound outlet 118, so that the audio output from the two first speakers 12 and the second speaker 13 disposed in the housing 11 respectively exit from the first sound outlet 117 and the second sound outlet 118, thereby realizing stereo output when the terminal 100 displays a horizontal screen, and the second sound outlet 118 of the back surface 115 is not easily blocked when the terminal 100 is held. In the embodiment shown in fig. 1 and 2, the top wall 111 and the bottom wall 112 are both opened with a first sound outlet 117, and the back surface 115 is opened with a second sound outlet 118.
The two first speakers 12 are disposed at positions where the first sound outlet hole 117 is located, for example, the two first speakers 12 are disposed at positions corresponding to the first sound outlet hole 117 of the top wall 111 and the first sound outlet hole 117 of the bottom wall 112, respectively, or the two first speakers 12 are disposed at positions corresponding to the first sound outlet holes 117 of the two opposite side walls 113, respectively, and the sound cavities of the first speakers 12 are disposed opposite to the first sound outlet hole 117, so that the left channel signal and the right channel signal respectively output by the two first speakers 12 are directly output from the corresponding first sound outlet holes 117, thereby shortening the propagation path of the audio in the housing 11 and reducing the loss of the audio.
The two first speakers 12 are designed symmetrically, the connection parallel side wall 113 of the two first speakers 12 (for example, the connection parallel side wall 113 at the center of the two first speakers 12, and the two first speakers 12 may be the same speaker, that is, the audio output parameters of the two first speakers 12 are the same, and compared to the current two speakers which are designed asymmetrically, for example, one is an earpiece and one is a bottom speaker, and the sound field balance of the asymmetric dual speakers is poor, the two first speakers 12 designed symmetrically make the sound fields of the two first speakers 12 received when the user holds the terminal 100 substantially balanced.
Referring to fig. 3, the second speaker 13 is disposed at the position of the second sound outlet 118. If the second speaker 13 is disposed at the position of the second sound outlet 118 of the sidewall 113, or the second speaker 13 is disposed at the position of the second sound outlet 118 of the back 115, and the sound cavity of the second speaker 13 is disposed opposite to the second sound outlet 118, so that the audio signal obtained by mixing the left channel signal and the right channel signal output by the second speaker 13 directly exits from the second sound outlet 118, the propagation path of the audio in the housing 11 is shortened, and the loss of the audio is reduced.
The second speaker 13 is disposed between the two first speakers 12, and the distance between the second speaker 13 and the two first speakers 12 is the same, for example, the length of the line connecting the center of the second speaker 13 and the center of each first speaker 12 is the same. In this way, it can be ensured that the second loudspeaker 13 does not affect the sound field equality of the two first loudspeakers 12 when enhancing the sound fields of the two first loudspeakers 12.
When the second speaker 13 is disposed on the back surface 115, the speaker is less affected by the width of the edge of the housing 11 (such as the top wall 111, the bottom wall 112 and the side wall 113) that is available for installation, resulting in a larger volume, and the volume of the sound cavity of the second speaker 13 can be larger than that of the sound cavity of the first speaker 12, so as to realize a large sound cavity design of the second speaker 13 and improve the sound effect of the second speaker 13. Wherein, the sound cavity includes a front cavity and a back cavity, in order to enhance the sound reflection effect, the volume of the front cavity of the second speaker 13 can be set larger than the volume of the front cavity of the first speaker 12, and in order to enhance the sound enhancement effect of the second speaker 13, the volume of the back cavity of the second speaker 13 can be set larger than the volume of the back cavity of the first speaker 12.
Referring to fig. 1, in order to enlarge the volume of the sound cavity of the second speaker 13, when designing the battery 14, the battery 14 may be arranged in a ring shape, the ring-shaped battery 14 is installed in the housing 11 (e.g., on the back surface 115), and the ring-shaped battery 14 encloses the installation space 119 of the second speaker 13, so that the second speaker 13 with a large sound cavity may be arranged in the installation space 119 of the second speaker 13, or a plurality of second speakers 13, that is, the ring-shaped battery 14 is arranged around the second speaker 13.
As shown in fig. 1, the battery 14 is disposed at a central position of the housing 11, the circuit board 15 includes a first sub-board 151 and a second sub-board 152, which are respectively disposed at two sides of the annular battery 14, and the second speaker 13 is located in the installation space 119 surrounded by the annular battery 14, it can be understood that the center of the installation space 119 may be disposed equally to the center of each first speaker 12, so as to ensure that the second speaker 13 does not affect the sound field balance of the two first speakers 12 when the sound fields of the two first speakers 12 are enhanced after the second speaker 13 is installed in the installation space 119.
As shown in fig. 3, the second speaker 13 may be disposed on the side wall 113, or the second speaker 13 may be disposed on the back surface 115, but near the side wall 113. Therefore, the second loudspeaker 13 is not influenced by the narrow width of the side wall 113, and a large sound cavity design is realized. The first sub-board 151 and the second sub-board 152 are vertically disposed to form an "L" shaped circuit board 15, and the first sub-board 151, the second sub-board 152 and the housing 11 enclose an accommodating space 120 to accommodate the battery 14, and the battery 14 may be rectangular and disposed in the accommodating space 120.
Referring to fig. 1 and fig. 4, the audio control method according to the embodiment of the present application is applied to the audio playing device 10 according to any of the above embodiments, and the audio control method includes:
011: outputting the left channel signal through a first speaker 12; (ii) a
012: outputting the right channel signal through another first speaker 12; and
013: an audio signal in which a left channel signal and a right channel signal are mixed is output through a second speaker 13 located between two first speakers 12.
The audio playing apparatus 10 further includes a processor 16, wherein the processor 16 is configured to control the two first speakers 12 to output a left channel signal and a right channel signal, respectively; an audio signal in which a left channel signal and a right channel signal are mixed is output through a second speaker 13 located between two first speakers 12. That is, steps 011 and 012 can be implemented by processor 16 in conjunction with two first speakers 12, and step 013 can be implemented by processor 16 in conjunction with second speaker 13.
Specifically, when the audio playing apparatus 10 performs audio output on an input audio signal, a left channel signal and a right channel signal in the input audio signal are first acquired, and then the left channel signal and the right channel signal are respectively output through the two first speakers 12, so as to output stereo sound through the two first speakers 12. Then, the processor 16 mixes the left channel signal and the right channel to output the mixed signal. For example, a left channel signal and a right channel signal are mixed to generate a stereo audio signal, and the second speaker 13 is controlled to output the stereo audio signal, so as to realize stereo enhancement and improve the loudness and sound field of the audio playing apparatus 10; for another example, a left channel signal and a right channel signal are mixed to generate a stereo audio signal; filtering the stereo audio signal to filter medium and high frequency audio signals in the stereo audio signal, thereby generating a low frequency audio signal; and then controls the second speaker 13 to output a low-frequency audio signal, thereby realizing low-frequency enhancement and improving the loudness and sound field of the audio playing device 10.
In other embodiments, when the two first speakers 12 output the left channel signal and the right channel signal respectively, each first speaker 12 may be controlled to output the left channel signal and the right channel signal simultaneously, and when the first speakers 12 output the left channel signal and the right channel signal simultaneously, the first speakers 12 may perform sound mixing to obtain a stereo audio signal, and then perform output, that is, both the two first speakers 12 output the stereo audio signal, so as to improve the loudness and sound field of the stereo audio output.
Referring to fig. 1 and 5, in some embodiments, the audio control method further includes:
014: detecting whether the left channel signal and/or the right channel signal have abnormality or not;
015: if the left channel signal or the right channel signal is abnormal, controlling the first loudspeaker 12 and the second loudspeaker 13 which are not abnormal to output the left channel signal and the right channel signal respectively; and
016: if the left channel signal and the right channel signal are both abnormal, the second speaker 13 is controlled to output a stereo audio signal generated by mixing the left channel signal and the right channel signal.
In some embodiments, processor 16 may be configured to detect whether an anomaly exists in the left channel signal and/or the right channel signal; if the left channel signal or the right channel signal is abnormal, controlling the first loudspeaker 12 and the second loudspeaker 13 which are not abnormal to output the left channel signal and the right channel signal respectively; and if the left channel signal and the right channel signal are both abnormal, controlling the second loudspeaker 13 to output a stereo audio signal generated after mixing the left channel signal and the right channel signal. That is, step 014, step 015 and step 016 may be implemented by the processor 16.
Specifically, when the user holds the terminal 100, the first speaker 12 and/or the second speaker 13 may be blocked or even damaged, so that the emitted sound is small or even cannot emit sound, when the first speaker 12 outputs the left channel signal, the first speaker 12 may detect an abnormality of the left channel signal and the right channel signal, for example, when the first speaker 12 is blocked, the reflection intensity of the left channel signal and the right channel signal in the sound cavity is high, and when the second speaker 13 is blocked, the reflection intensity of the audio signal obtained by mixing the left channel signal and the right channel signal in the sound cavity is high, so that whether the first speaker 12 (the second speaker 13) has an abnormality may be determined by detecting whether an audio parameter of the audio signal output by the first speaker 12 (the second speaker 13) is abnormal (e.g., whether the loudness is greater than a predetermined loudness to determine that the audio signal is blocked, and when the loudness is not, the abnormality may be determined).
When there is an abnormality in the left channel signal or the right channel signal (i.e., when there is an abnormality in one of the first speakers 12), the left channel signal and the right channel signal may be output through the first speaker 12 and the second speaker 13, respectively, where there is no abnormality, so that a stereo output after a hole is blocked or damaged is realized. When the left channel signal and the right channel signal are both abnormal (i.e. both the first speakers 12 are abnormal), the second speaker 13 directly outputs the stereo audio signal generated after the left channel signal and the right channel signal are mixed, so as to realize stereo output after hole blockage or damage. When the audio signal output by the second speaker 13 is abnormal, the two first speakers 12 output the left channel signal and the right channel signal respectively, so as to realize the stereo output after hole blockage or damage. In this way, stereo output can be realized regardless of whether the first speaker 12 or the second speaker 13 is clogged or damaged.
Referring to fig. 1 and 6, in some embodiments, the audio control method further includes:
017: when the audio input signals are various, the two first speakers 12 are controlled to output one audio input signal, and the second speaker 13 outputs the rest of the various audio input signals.
In some embodiments, the processor 16 is further configured to control the two first speakers 12 to output one audio input signal and the second speaker 13 to output the rest of the plurality of audio input signals when the plurality of audio input signals are different. That is, step 017 may be carried out by processor 16.
Specifically, when the terminal 100 performs audio output, the audio input signals may be multiple, for example, the audio input signals output from different applications are taken as one audio input signal, for example, the audio input signal a output by an application that releases black voice and the audio input signal B output by a game application are simultaneously played by the audio playing apparatus 10, it can be understood that since the game needs to perform sound discrimination to assist user operation, stereo output of left and right channels needs to be realized, and the black voice only needs to be clearly heard, the processor 16 may use the audio input signal B as main audio, and output a left channel signal and a right channel signal of the main audio through two first speakers 12 respectively, so as to assist the user to operate the game, and use the audio input signal a as background audio, and mix the left channel signal and the right channel signal of the background audio, and then generate a stereo audio signal, which is output through the second speaker 13. Of course, if there are more audio input signals, one of the audio input signals is output as main audio through the two first speakers 12, and the remaining audio input signals among the audio input signals are output as background audio through the second speakers 13.
In the audio playing device 10, the terminal 100 and the audio control method according to the embodiment of the application, the two first speakers 12 are disposed in the casing 11 to output the left channel signal and the right channel signal, so that the audio playing device 10 can not only realize stereo audio output, but also realize output of the audio signal after mixing the left channel signal and the right channel signal through the second speaker 13 disposed between the two first speakers 12 to enhance loudness and sound field of stereo audio, thereby improving playing tone quality of the audio playing device 10. When there is an abnormality in the first speaker 12 or the second speaker 13, stereo output can still be realized. In addition, the playing of different audio input signals can be realized through the first speaker 12 and the second speaker 13, respectively, so as to adapt to different audio playing scenes of the terminal 100.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention, which is defined by the claims and their equivalents.
