The control device 4 may be independent or may be part of the electronic apparatus 100, and in this embodiment, the control device 4 is part of the electronic apparatus 100.
Based on the above-mentioned structure, fig. 4 is a schematic diagram of an embodiment of a control method of an electronic device 100 according to the present invention, referring to fig. 4, the control method of the electronic device 100 includes:
step S10, acquiring a sound emitting mode of the electronic equipment 100;
The sound emitting mode of the electronic device 100 includes an earpiece mode in which it is desired that the sound emitted by the electronic device 100 is heard only by the user and is leaked to the surrounding environment as little as possible, and a play mode in which it is desired that the sound is better conducted to the surrounding environment.
Step S20, when the sound emitting mode of the electronic device 100 is the earpiece mode, controlling the second sound hole 12 to communicate with the rear cavity 14, where the first sound hole 11 and the sound wave emitted by the second sound hole 12 form a sound dipole, and at the same time, the control device 4 obtains a real-time sound signal collected by the sound pickup unit 3;
when the sound emitting mode of the electronic device 100 is the earpiece mode, the real-time sound signal needs to be collected by the sound pickup unit 3, where the real-time sound signal includes an environmental noise signal of an environment where the electronic device 100 is located and an echo signal of sound emitted by the electronic device 100, where the echo signal is a reflected wave formed by the sound waves emitted from the first sound hole 11 and the second sound hole 12 of the electronic device 100 after being converged and passing through an obstacle, and it is obvious that the echo signal is different from the sound wave signal actually emitted from the first sound hole 11.
Step S30, according to the real-time sound signal, acquiring an environmental noise signal value of the environment where the electronic device 100 is located and an echo signal value generated by the electronic device 100;
when the real-time sound signal is received, the environmental noise signal value of the environment where the electronic device 100 is located and the echo signal value generated by the electronic device 100 can be obtained, and specifically, how to separate the real-time sound signal into the environmental noise signal and the echo signal can be completed by adopting the prior art, which is not described herein.
Step S40, adjusting the volume of the sound generating unit 2 according to the environmental noise signal value, the echo signal value, and the current volume value of the sound generating unit 2.
The echo signal value is a sound signal reflecting the electronic device 100 conducted to the environment, that is, a sound signal obtained by combining sound waves emitted from the first sound hole 11 and the second sound hole 12 of the electronic device 100, that is, a sound level emitted from the electronic device 100 heard in the environment, and the current volume value of the sound emitting unit 2 is a sound level at the first sound hole 11, that is, a sound level heard by the user when the user approaches the first sound hole 11 in the earpiece mode, so that the sound level of the sound emitting unit 2 can be adjusted according to the environmental noise signal value, the echo signal value, and the current sound level of the sound emitting unit 2, on one hand, the echo signal value is smaller when the current sound level of the sound emitting unit 2 is enough, that is, the user can clearly hear the sound signal, and the sound signal leaked to the environment is smaller.
Further, in the embodiment of the present invention, on the premise that the electronic device 100 further includes a switching mechanism for controlling the switching of the second sound hole 12, the step S20 includes:
step S21, when the sound emitting mode of the electronic device 100 is the earpiece mode, controlling the switching mechanism 5 to switch to the second state;
step S22, when the second sound hole 12 is communicated with the rear cavity 14, acquiring a real-time sound signal acquired by the sound pickup unit 3;
After step S10, further includes:
step S50, when the play mode of the electronic device 100 is the play mode, controlling the switching mechanism 5 to switch to the first state.
That is, in the case where the switching mechanism is present, the switching mechanism may be controlled to switch to the second state in the earpiece mode, so that the sound wave of the first sound hole 11 and the sound wave of the second sound hole 12 may form a dipole effect for the user in the surrounding environment, and for this reason, when the sound emitting mode of the electronic device 100 is the earpiece mode, the sound leakage may be reduced, and it is obvious that the second sound hole 12 is always open for the scheme where the switching mechanism is not provided. And for the external mode, the noise elimination effect caused by the existence of the second sound hole 12 and the first sound hole 11 is avoided, and the switching mechanism 5 is controlled to switch to the first state, so that the first sound hole 11 and the second sound hole 12 are communicated with the front cavity 13, and the sound is enough in the external mode.
In an embodiment of the present invention, step S40 includes:
Step S40a, adjusting the volume of the sound generating unit 2 according to the echo signal value and the magnitude relation between the current volume value of the sound generating unit 2 and the ambient noise signal value.
That is, in the embodiment of the present invention, the user cannot hear the sound of the first sound hole 11 of the electronic device, not only depending on the volume at the first sound hole 11, but also related to the noise of the environment, for example, when the environmental noise is small, the user can hear the sound of the smaller first sound hole 11, and when the environmental noise is large, the user needs the sound of the larger first sound hole 11 to hear the sound, and likewise, in the surrounding environment, the sound of the electronic device 100 cannot hear (i.e., the sound cannot leak clearly), and is not completely dependent on the echo signal value, and related to the surrounding environmental noise, for this reason, in the embodiment of the present invention, the volume of the sound generating unit 2 is adjusted according to the volume relationship between the echo signal value and the current volume value of the sound generating unit 2 and the environmental noise signal value, and the adjusting effect thereof is more accurate.
Specifically, in the embodiment of the present invention, step S40a includes:
step S41, dividing the echo signal value by the ambient noise signal value to obtain a first ratio, and dividing the current volume value of the sounding unit 2 by the ambient noise signal value to obtain a second ratio;
Step S42, adjusting the volume of the sounding unit according to a first ratio and a second ratio, wherein the first set ratio and the second set ratio are empirical values or experimentally measured values, the first set ratio is the ratio between an echo signal value and an environmental noise signal value when the environmental noise influences the listening of echoes, and the second set ratio is the ratio between the current volume value and the environmental noise signal value when the environmental noise influences the listening of sounds emitted by the sounding unit;
That is, in an embodiment of the present invention, the volume of the sound generating unit is controlled and adjusted by the ratio of the echo signal value to the ambient noise signal value and the ratio of the current volume value of the sound generating unit 2 to the ambient noise signal value, and when one of the ratio is larger, the influence of the noise on the respective sound is indicated to be larger, otherwise, the influence is smaller, and obviously, the present design is not limited to this, and the volume of the sound generating unit may also be adjusted by the difference value between the echo signal value and the ambient noise signal value and the difference value between the current volume value of the sound generating unit 2 and the ambient noise signal value.
Further, in the embodiment of the present invention, step S42 includes:
step S421, comparing the first ratio with a first set ratio, and comparing the second ratio with a second set ratio;
Step S422, when the first ratio is greater than the first set ratio and the second ratio is greater than the second set ratio, the volume of the sounding unit 2 is reduced;
step S423, increasing the volume of the sound generating unit 2 when the first ratio is smaller than the first set ratio and the second ratio is smaller than the second set ratio.
In this embodiment, by comparing the first ratio with the second ratio with the first set ratio and the second preset value, respectively, it can be determined according to the comparison result that the environmental noise affects the echo signal and the sound at the first sound hole 11, so as to control the volume of the sound generating unit according to the effect result, to ensure that the sound cannot leak, and meanwhile, the user can hear the sound at the first sound hole 11 more clearly.
Further, in the embodiment of the present invention, after step S421, the method further includes:
step S424, when the first ratio is greater than the first set ratio and the second ratio is smaller than
When the second set ratio is set, the volume of the sounding unit 2 is reduced, so that the first ratio reaches the first set ratio;
when the leakage contradicts the sound heard by the user, the leakage can be preferentially reduced, and of course, in other embodiments, the sound heard by the user can be preferentially ensured.
In step S425, when the first ratio is smaller than the first set ratio and the second ratio is larger than the second set ratio, the sound generating unit 2 is controlled to maintain the current sound volume value.
When the leakage is well controlled and the user hears louder, the current volume can not be adjusted.
