[0032] S110~S130: Steps DETAILED DESCRIPTION

[0033] Please refer to Figures 1 to 4. Figure 1 FIG. 1 is a diagram showing the appearance of a smart speaker 100 according to an embodiment of the present invention. Figure 2 Draw Figure 1 A functional block diagram of the smart speaker 100, Figure 3 Draw Figure 2 The trend diagram of the first ambient light brightness value BL1 and the second ambient light brightness value BL2 is shown in FIG. Figure 4 FIG. 1 is a schematic diagram of an equalizer 150 according to an embodiment of the present invention.

[0034] like Figure 1 As shown, the smart speaker 100 includes a housing 105, a first light sensor 110, a second light sensor 120, a speaker 130, and a processor 140. Although not shown, the smart speaker 100 further includes an amplifier connected to the processor 140 and the speaker 130 to amplify the signal transmitted to the speaker 130.

[0035] The first light sensor 110 is used to sense the first ambient light brightness value BL1. The second light sensor 120 is used to sense the second ambient light brightness value BL2. The speaker 130 is used to emit a sound V1. The processor 140 is electrically connected to the first light sensor 110, the second light sensor 120 and the speaker 130 and is used to control the sound effect of the sound V1 according to the first ambient light brightness value BL1 and the second ambient light brightness value BL2. In this way, the smart speaker 100 can emit the sound effect of the corresponding sound V1 according to the ambient brightness value, or automatically (actively) adjust the sound effect of the sound V1 according to the change of the ambient brightness value.

[0036] like Figure 1 As shown, the first light sensor 110, the second light sensor 120, the speaker 130 and the processor 140 are disposed in the housing 105. The first light sensor 110 and the second light sensor 120 are exposed from the housing 105 so as to sense the first ambient light L1 and the second ambient light L2. The first ambient light brightness value BL1 is the brightness value of the first ambient light L1, and the second ambient light brightness value BL2 is the brightness value of the second ambient light L2. The first ambient light L1 and the second ambient light L2 are incident on the first light sensor 110 and the second light sensor 120 from different directions in the environment, respectively. By sensing multiple ambient lights, the accuracy of determining the ambient mode can be increased. In detail, compared with one ambient light brightness value, the difference between the two ambient light brightness values ​​provides an additional reference for determining the ambient mode. For example, among multiple ambient light brightness values, one ambient light brightness value can be used as a benchmark, and the differences of the remaining ambient light brightness values ​​relative to the benchmark can be used as an additional reference for determining the ambient mode.

[0037] As shown in FIGS. 1 and 2 , the smart speaker 100 further includes a volume increase button 106A, a volume decrease button 106B, a start / pause button 106C, a mute / amplify button 106D, etc., which can be configured on the control panel of the smart speaker 100. In addition, the first light sensor 110 and the second light sensor 120 can also be configured on the control panel.

[0038] As shown in FIGS. 1 and 2 , the processor 140 is further used to obtain a comprehensive ambient light gain value (or comprehensive ambient light brightness value) BLV according to the first ambient light brightness value BL1 and the second ambient light brightness value BL2; and to control the sound effect of the sound V1 according to the comprehensive ambient light gain value BLV. In addition, the processor 140 is, for example, a system on a chip (SoC).

[0039] As shown in Table 1 below, the corresponding relationship R1 between multiple comprehensive ambient light gain values ​​BLV and multiple sound effect modes VM is listed. The processor 140 is further used to: obtain the sound effect mode VM corresponding to one of the comprehensive ambient light gain values ​​BLV from the corresponding relationship R1; and control the sound effect of the sound V1 according to the obtained sound effect mode VM. For example, based on the comprehensive ambient light gain value BLV obtained by the processor 140 being 100 lumens (Luminance), the processor 140 adjusts the sound effect of the sound V1 to the sleep mode. Different sound effect modes VM can correspond to different comprehensive ambient light gain values ​​BLV.

[0040] Table 1

[0041] Sound Mode VM Comprehensive ambient light gain value BLV (lumens) Sleep mode (sleep) 100 Relaxation mode (comfort) 600 Outdoor mode (outdoor) 1000 Live Mode 650 Music Mode (Vocal) 500 Rock mode (rock) 800

[0042] The correspondence relationship R1 may be acquired in advance by software simulation, field simulation, etc. After acquiring the correspondence relationship R1, the correspondence relationship R1 may be pre-stored in the processor 140 or in a memory electrically connected to the processor 140 for access by the processor 140.

[0043] like Figure 3As shown, in the process of simulating a sound effect mode, the first ambient light brightness value BL1 and the second ambient light brightness value BL2 may change over time, and the aforementioned comprehensive ambient light gain value BLV is calculated from the change trends of the first ambient light brightness value BL1 and the second ambient light brightness value BL2. In one embodiment, the processor 140 obtains the brightness (weight) average value of the first ambient light brightness value BL1 and the second ambient light brightness value BL2; and uses this brightness average value as the comprehensive ambient light gain value BLV. The aforementioned brightness average value is, for example, the brightness average value (for example, the average of the sum or the average of the difference) of the first ambient light brightness value BL1 and the second ambient light brightness value BL2 at at least one time point, or the average of several brightness average values ​​(for example, the average of the sum or the average of the difference) of the first ambient light brightness value BL1 and the second ambient light brightness value BL2 at several time points. In addition, the determination method of the comprehensive ambient light gain value BLV is not limited to the average brightness value, and can also be other statistical methods, algorithms, mathematical methods, etc. In one embodiment, the integrated ambient light gain value BLV may be determined according to the ratio of the first ambient light brightness value BL1 to the second ambient light brightness value BL2. Alternatively, the integrated ambient light gain value BLV may be determined according to the incident angle of the first ambient light L1 incident on the first light sensor 110 and / or the incident angle of the second ambient light L2 incident on the second light sensor 120.

[0044] like Figure 4 As shown, the sound effect mode VM includes a plurality of audios and a plurality of decibel values ​​corresponding to these audios. The processor 140 is further used to: load an equalizer 150; and input these audios and these decibel values ​​into the equalizer 150 so that the sound V1 has sound effects. Different sound effect modes VM have different corresponding relationships between audios and audios. In this embodiment, the equalizer 150 is, for example, an application.

[0045] Please refer to Figure 5 , which shows Figure 1 Flow chart of the sound effect control method of the smart speaker 100.

[0046] In step S110 , the first light sensor 110 senses a first ambient light brightness value BL1 .

[0047] In step S120 , the second light sensor 120 senses the second ambient light brightness value BL2 .

[0048] In step S130 , the processor 140 controls the sound effect of the sound V1 emitted by the speaker 130 according to the first ambient light brightness value BL1 and the second ambient light brightness value BL2 .

[0049] The remaining steps of the sound effect control method have been described above and will not be repeated here.

[0050] In summary, the embodiments of the present invention provide a smart speaker and a sound effect control method using the same. The smart speaker can detect the brightness of ambient light and its changes, and adjust the sound effect of the sound emitted accordingly.

[0051] In summary, although the present invention has been disclosed as above by the embodiments, it is not intended to limit the present invention.
