[0046] Generally, when using two speakers with the same resonant frequency, using a low-output speaker results in poor call quality, while using a high-output speaker makes it difficult to secure mounting space. If two speakers with different resonant frequencies are used, the cancellation band is limited, and it is difficult to prevent call leakage. Speakers of different sizes can cause differences in resonant frequencies. Therefore, these problems exist in electronic devices containing two speakers of different sizes.

[0047] The electronic device including the speaker and the audio output control method of the present invention are intended to prevent call leakage by using speakers having different resonant frequencies.

[0048] The electronic device including the speaker and the audio output control method of the present invention can prevent speaker performance degradation and secure mounting space by outputting an inverse phase signal using speakers having different resonant frequencies.

[0089] In one embodiment, in operation 505, instructions, when executed individually or collectively by at least one processor (110), may cause the electronic device (100) to output a generated leak sound cancellation signal through a second speaker (e.g., a second speaker (220), a fifth speaker of a third speaker (310), or a second speaker circuit) with a delay of a set time. For example, the set time may include the time to generate a leak sound cancellation signal based on an audio signal. Using a time delay during a call can minimize sound leakage.

[0090] In one embodiment, in operation 505, instructions may be executed individually or collectively by at least one processor (110), so that the electronic device (100) may output a first leakage sound cancellation signal to a second speaker (e.g., the second speaker (220), the fifth speaker of the third speaker (310), or the second speaker circuit) by applying at least one of a set phase adjustment value or amplitude adjustment value for each frequency in a first frequency band to an inverse phase signal of the audio signal.

[0091] In one embodiment, the first speaker (210), the fourth speaker of the third speaker (310), or the first speaker circuit of the third speaker (310) may have a first value as a resonant frequency. The second speaker (220), the fifth speaker of the third speaker (310), or the second speaker circuit of the third speaker (310) may have a second value as a resonant frequency. The lower limit of the set first frequency band may be greater than either the first value or the second value. In other words, the set frequency band includes a first frequency band having a lower limit value corresponding to the larger of the first value and the second value. The upper limit of the first frequency band may be pre-set.

[0092] For example, if the first value is 600 Hz and the second value is 800 Hz, the lower limit of the first frequency band may include 800 Hz. In this case, the first frequency band (bandwidth) may include an audible frequency band of 800 Hz or higher. The first leakage sound cancellation signal may include the first frequency band. The frequency band may be a frequency band that exceeds the resonance frequency of the first speaker and / or the resonance frequency of the second speaker.

[0093] In one embodiment, in the operation of 505, instructions may, when executed individually or collectively by at least one processor (110), cause the electronic device (100) to generate a second leak sound cancellation signal generated by applying at least one of a set phase adjustment value or amplitude adjustment value for each frequency in a second frequency band to an inverse phase signal of the audio signal, a third leak sound cancellation signal generated by applying at least one of a set phase adjustment value or amplitude adjustment value for each frequency in a third frequency band to an inverse phase signal of the audio signal, and a fourth leak sound cancellation signal generated by applying at least one of a set phase adjustment value or amplitude adjustment value for each frequency in a fourth frequency band to an inverse phase signal of the audio signal. When instructions are executed individually or collectively by at least one processor (110), the electronic device (100) may output to the second speaker (e.g., the second speaker (220), the fifth speaker of the third speaker (310), or the second speaker circuit) while an audio signal is output through the first speaker (e.g., the first speaker (210), or the fourth speaker of the third speaker (310), or the first speaker circuit).

[0094] In one embodiment, the first speaker circuit of the first speaker (210) or the third speaker (310) may have a first value as the resonant frequency. The second speaker circuit of the second speaker (220) or the third speaker (310) may have a second value as the resonant frequency.

[0095] For example, if the first value is 600 Hz and the second value is 800 Hz, the lower limit of the first frequency band may include 800 Hz. The upper limit of the first frequency band may be set. For example, the upper limit of the first frequency band may be set to 1200 Hz. The frequency band may be a frequency band that exceeds the resonant frequency of the first speaker and / or the resonant frequency of the second speaker.

[0096] In one embodiment, the lower limit of the second frequency band may be greater than the upper limit of the first frequency band. For example, the lower limit of the second frequency band may be greater than 1200 Hz. However, it is not limited thereto, and the lower limit of the second frequency band may correspond to the lower limit of the first frequency band. The lower limit of the second frequency band may include the lower limit of the first frequency band. The lower limit of the second frequency band may be equal to the upper limit of the first frequency band.

[0097] In one embodiment, the third frequency band may have an upper limit value smaller than the larger of the first value and the second value, and a lower limit value larger than the smaller of the first value and the second value. For example, the third frequency band may have an upper limit value smaller than 800 Hz and a lower limit value larger than 600 Hz.

[0098] In one embodiment, the upper limit of the fourth frequency band may be smaller than the larger of the first value and the second value. For example, the upper limit of the fourth frequency band may be smaller than 600 Hz.

[0099] In one embodiment, in the operation of 505, when instructions are executed individually or collectively by at least one processor (110), the electronic device (100) may synthesize at least one of a first leak sound cancellation signal, a second leak sound cancellation signal, a third leak sound cancellation signal, and a fourth leak sound cancellation signal to generate a leak sound cancellation signal and output it to a second speaker (e.g., a second speaker (220) or a second speaker circuit).

[0100] FIG. 6 is a drawing showing an audio signal processing circuit (e.g., a first audio signal processing circuit (610) or a second audio signal processing circuit (611)) according to one embodiment of the present disclosure.

[0101] In one embodiment, the electronic device (100) may include a first audio signal processing circuit (610), a second audio signal processing circuit (611), a first speaker (210), and a second speaker (220). The first speaker (210) may correspond to the first speaker circuit of the third speaker (310) as well as the first speaker (210) of FIG. 2. The second speaker (220) may correspond to the second speaker circuit of the third speaker (310) as well as the second speaker circuit of the second speaker (220) of FIG. 2.

[0102] In one embodiment, the first audio signal processing circuit (610) and the second audio signal processing circuit (611) may each be implemented by a processor (110). For example, the processor (110) may include the first audio signal processing circuit (610) and the second audio signal processing circuit (611).

[0103] In one embodiment, the first audio signal processing circuit (610) can process the audio signal and transmit it to the first speaker circuit of the first speaker (210) or the third speaker (310). The first speaker circuit of the first speaker (210) or the third speaker (310) can output the received audio signal.

[0104] In one embodiment, the first audio signal processing circuit (610) can process an audio signal and transmit it to the first speaker (210) or the second speaker (220). An inverse phase signal of the audio signal generated by the second audio signal processing circuit (611) can be transmitted to and output to the first speaker (210) or the second speaker (220). For example, when the audio signal generated by the first audio signal processing circuit (610) is output through the first speaker (210), the second speaker (220) can output an inverse phase signal of the audio signal generated by the second audio signal processing circuit (611). For example, when the audio signal generated by the first audio signal processing circuit (610) is output through the second speaker (220), the first speaker (210) can output an inverse phase signal of the audio signal generated by the second audio signal processing circuit (611).

[0105] In one embodiment, the second audio signal processing circuit (611) can generate an inverse phase signal of the audio signal and generate a leakage sound cancellation signal by applying at least one of a set phase adjustment value or amplitude adjustment value for each frequency to the inverse phase signal of the audio signal. The generated leakage sound cancellation signal can be output through the second speaker circuit of the second speaker (220) or the third speaker (310).

[0106] In one embodiment, the second audio signal processing circuit (611) may include a fast Fourier transform (FFT), at least one band-pass filter, a phase or amplitude adjustment circuit for each frequency band, an inverse fast Fourier transform (IFFT), and / or a mixing circuit. In one embodiment, the second audio signal processing circuit (611) may further include a frequency output (FO) analysis circuit. The frequency output (FO) analysis circuit can remove echo components of the audio signal.

[0107] A fast Fourier transform (FFT), at least one band-pass filter, a frequency band-specific phase or amplitude adjustment circuit, an inverse fast Fourier transform (IFFT), a frequency output (FO) analysis circuit, and / or a mixing circuit may be implemented by a computer program. When the instructions included in the computer program are executed by the processor (110), the electronic device (100) may perform an FFT (fast Fourier transform) operation, a band-pass filter operation, a frequency band-specific phase or amplitude adjustment operation, an IFFT (inverse fast Fourier transform) operation, a frequency output (FO) analysis operation, and / or a mixing operation on an audio signal.

[0108] In one embodiment, the second audio signal processing circuit (611) can measure the performance of the first speaker circuit of the first speaker (210) or the third speaker (310), the second speaker circuit of the second speaker (220) or the third speaker (310), and generate a leakage sound cancellation signal that reflects the delay condition by taking into account the delay occurring in the circuit and software processing.

[0109] In one embodiment, the delay condition can be found by simultaneously playing an orthogonal signal to the first speaker circuit of the first speaker (210) or the third speaker (310) and the second speaker circuit of the second speaker (220) or the third speaker (310).

[0110] FIG. 7 is a graph showing the result of adjusting the phases of speakers with different resonant frequencies according to one embodiment of the present disclosure.

[0111] In FIG. 7, the x-axis represents frequency and the y-axis represents phase. Graph 701 is a graph showing the phase change of an audio signal output through the first speaker (210) at different frequencies, and graph 703 is a graph showing the phase change of an audio signal output through the second speaker (220) at different frequencies. The audio signal output through the first speaker (210) and the audio signal output through the second speaker (220) may have different output (or amplitude) and phases because the resonance frequencies and / or sensitivities of each speaker are different.

[0112] In one embodiment, when instructions are executed individually or collectively by at least one processor (110), the electronic device (100) can be controlled to apply at least one of a set phase adjustment value or an amplitude adjustment value for each frequency to an audio signal in a set frequency band (710) so that the phases output from the first speaker (210) and the second speaker (220) match.

[0113] FIG. 8 is a graph showing the result of measuring an audio signal (805) measured by an electronic device (100) according to one embodiment of the present disclosure outputting a first leakage sound cancellation signal (803) in a first frequency band (810).

[0114] In FIG. 8, the x-axis represents frequency and the y-axis represents output (dB). Referring to FIG. 8, graph 801 is a graph showing the output of a leaking audio signal output from a first speaker (210) in a first frequency band (810), graph 803 is a graph showing the output of an audio signal in a frequency band when destructive interference is received from multiple speakers with the same resonant frequency band, and graph 805 is a graph showing the output of an audio signal in a frequency band when the audio signal in the first frequency band (810) of the present invention is destructive interference by a first leak sound cancellation signal.

[0115] Referring to graph 803, in multiple speakers with the same resonant frequency band, it may be easy to block leakage sound from the receiver simply by generating an inverse phase signal. Referring to graph 805, an electronic device including speakers with different resonant frequencies can block leakage sound with substantially the same performance as blocking leakage sound from multiple speakers with the same resonant frequency band by controlling the inverse phase output for each frequency band.
