[0023] Figure 1 is a structural schematic diagram of a hybrid power sound system according to some embodiments of the present specification.

[0024] In some embodiments, the sound system 100 can include a first power supply 110, a second power supply 120, a control system 130 and an output module 140, the control system 130 being connected with the output module 140; the first power supply 110 is provided with a first switch 111 between the first power supply 110 and the external power supply, and the second power supply 120 is provided with a second switch 121 between the second power supply 120 and the external power supply; the control system 130 is connected with the first switch 111 and the second switch 121 respectively; the disconnection or closure of the first switch 111 and the second switch 121 is controlled by the control system 130, the control system 130 is connected with the external power supply through the first power supply 110 or the second power supply 120; the output module 140 is configured to convert an audio signal into a sound output.

[0025] The first power supply 110 is a power supply with high energy conversion efficiency for converting an external power supply and supplying power to the sound system 100.

[0026] The external power supply refers to a power supply that provides power to the sound system 100 from the outside. For example, the external power supply can be a mains power supply, i.e. an alternating current power supply provided by a city power grid. According to different countries or cities, the commonly used alternating current power frequency of the mains power supply can be 50Hz, 60Hz, etc., and the domestic alternating current voltage is distributed between 100V and 380V.

[0027] In some embodiments, as shown in FIG. 1, the first power supply 110 is connected to an external power supply through a first switch 111. Figure 1

[0028] The first switch 111 is a component for disconnecting or connecting the first power supply 110 and the external power supply. For example, when the first switch 111 is disconnected, the first power supply 110 is disconnected from the external power supply, and the first power supply 110 cannot supply power to the sound system 100 through the external power supply. When the first switch 111 is connected, the first power supply 110 is connected to the external power supply, and the first power supply 110 can supply power to the sound system 100 through the external power supply.

[0029] In some embodiments, the first switch 111 can be a relay. The relay is an automatic switch. In some embodiments, the relay can be controlled by low voltage and small current to control high voltage and large current, that is, remote control and automatic control can be achieved.

[0030] In some embodiments, the first power supply 110 can be a switching power supply.

[0031] The switching power supply, also known as a switching power supply or switching converter, is a high-frequency power conversion device. In some embodiments, the switching power supply can be configured to convert the input AC power into a high-frequency pulse current, store the power in an inductor and capacitor element, and release the power according to the required voltage requirements by using the characteristics of the inductor and capacitor to change the output voltage or current.

[0032] The voltage stabilization of the switching power supply is achieved by adjusting the on and off time of the transistor. Since the switching element consumes very little energy when it is on and off, the energy conversion efficiency of the switching power supply is high, usually reaching 80%-98%.

[0033] In some embodiments, when the switching power supply is used to supply power to the sound system 100, the sound system 100 can have lower performance indicators and higher energy conversion efficiency.

[0034] The performance indicator is a relevant indicator reflecting the performance of the sound system. For example, the performance indicator can include the sound perception dynamic range and signal-to-noise ratio of the sound output by the sound system 100. For example, when the switching power supply is connected, the sound perception dynamic range of the sound system 100 can be 105dB, and the signal-to-noise ratio can be about 105dB. The energy conversion efficiency refers to the ratio of the output power to the input power of the power supply. For example, when the switching power supply is used by the sound system 100, the energy conversion efficiency can be about 92%.

[0035] ​In some embodiments of the present disclosure, the first power supply is configured as a switching power supply, so that when the first power supply is used to supply power to the audio system 100, the energy conversion efficiency is high, the power consumption of the audio system is low, and the power saving effect is achieved. In addition, the switching power supply has small size and low heat generation, and can be used for a long time without being easily damaged.

[0036] The second power supply 120 is a power supply with high stability for converting an external power supply and supplying power to the audio system 100. Stability reflects the degree of fluctuation of the output voltage of the power supply. For example, the stability can be calculated by the following method: the maximum fluctuation value of the output voltage / the output voltage under nominal input conditions*100%. The maximum fluctuation value of the output voltage refers to the absolute value of the maximum value of the change of the output voltage caused by the change of the input voltage under the nominal input conditions. The nominal input conditions refer to the input voltage within a specified range. For example, if the rated input voltage is 220V, the specified range can be rated input voltage±10%, i.e. 198V-242V.

[0037] In some embodiments, as shown in FIG. 1, the second power supply 120 is connected to the external power supply through the second switch 121. Figure 1

[0038] The second switch 121 is a component for disconnecting or conducting the connection between the second power supply 120 and the external power supply. For example, when the second switch 121 is disconnected, the connection between the second power supply 120 and the external power supply is disconnected, and at this time the second power supply 120 cannot supply power to the audio system 100 through the external power supply. When the second switch 121 is connected, the connection between the second power supply 120 and the external power supply is formed, and at this time the second power supply 120 can supply power to the audio system 100 through the external power supply.

[0039] In some embodiments, the second switch 121 can be a relay. For the description of the relay, please refer to the foregoing description.

[0040] In some embodiments, the second power supply 120 can be a linear power supply.

[0041] The linear power supply refers to a power supply that changes the conduction degree of the transistor to change the output voltage and current. In some embodiments, the linear power supply is configured to reduce the voltage amplitude of the input alternating current through a transformer, obtain pulse direct current through a rectifier circuit, and obtain a direct current voltage with a small ripple through a filter.

[0042] The voltage stabilization of the linear power supply is based on the comparison of the difference between the output voltage and the reference voltage by the voltage feedback circuit, and the conduction degree of the transistor is adjusted in real time to adjust the output voltage.

[0043] ​In some embodiments, when the audio system 100 is powered by the linear power supply, the audio system 100 can have higher performance indicators and lower energy conversion efficiency. For example, the listening dynamic range can be 125 dB, the signal-to-noise ratio can be 125 dB or more, and the energy conversion efficiency can be about 60%.

[0044] In some embodiments of the present specification, since the adjustment of the conduction degree of the transistor produces a linear change, the linear power supply produces small ripple and small external interference, and can achieve very high stability. By setting the second power supply as a linear power supply, the performance indicators of the audio system 100 can be improved when the audio system is powered by the second power supply, and the user experience can be improved.

[0045] The control system 130 is configured to control the audio system 100 to implement various functions. For example, the control system 130 can control the audio system 100 to implement a sound playing function. For another example, the control system 130 can control the power supply of the audio system 100 by controlling the first switch 111 and the second switch.

[0046] In some embodiments, the control system 130 can control the opening or closing of the first switch 111 and the second switch 121, and the control system 130 is connected to the external power supply through the first power supply 110 or the second power supply 120. For example, when the first switch 111 and the second switch 121 are electromagnetic relays, the control system 130 can control the opening or closing state of the contact through the magnetic field generated by the coil energization, thereby controlling the connection mode between the external power supply and the control system 130. For another example, when the first switch 111 and the second switch 121 are temperature relays, the control system 130 can control the opening or closing state of the contact by controlling the temperature change, thereby controlling the connection mode between the external power supply and the control system 130.

[0047] For more details about the control system 130, please refer to the corresponding description of Figure 2 .

[0048] The output module 140 refers to a module for outputting sound.

[0049] In some embodiments, the output module 140 can be connected to the control system 130. For example, the output module 140 can be electrically connected, communicatively connected, or the like to the control system 130.

[0050] In some embodiments, the output module 140 is configured to convert an audio signal into sound output. For more details about the output module, please refer to the related description of Figure 3 . Wherein, the audio signal can come from one or more sound sources. For example, the sound source can be a digital sound source, a CD, a vinyl record.

[0051] In some embodiments, the audio source can input the audio signal to the output module 140 or the control system 130 through an AUX interface, Bluetooth, or an HDMI interface.

[0052] In some embodiments of the present disclosure, by controlling the first switch and the second switch through the control system, the control system can be connected to the external power supply through the first power supply or the second power supply according to actual conditions. After one of the power supplies is turned on, the audio signal is converted into sound output through the output module connected to the control system, so as to meet the user's demand for sound quality or the demand for energy saving.

[0053] In some embodiments, the sound system 100 can include a first working mode and / or a second working mode. The first working mode and the second working mode are two working modes of the sound system 100 using different power supplies. In some embodiments, the sound system 100 can be set to use the first working mode by default or use the second working mode by default.

[0054] In some embodiments, the sound system 100 can further include other working modes, such as a working mode of timing switching the first switch and the second switch.

[0055] In some embodiments, when the sound system 100 is in the first working mode, the first switch 111 is open, the second switch 121 is closed, and the control system 130 is connected to the external power supply through the second power supply 120.

[0056] In some embodiments, the sound system 100 can be configured to be in the first working mode by default, that is, after the sound system 100 is connected to the external power supply, the control system 130 is connected to the external power supply through the second power supply 120, so that the sound system 100 has better performance indicators. In some embodiments, the user can set the sound system 100 to run in the first working mode, for example, the user can set it through the interaction module; the control system 130 can read the user's setting, control the first switch 111 to be open and the second switch 121 to be closed, so that the control system 130 is connected to the external power supply through the second power supply 120, to meet the user's performance requirements for the sound system 100. For related descriptions of the interaction module and user settings, see the corresponding description in Figure 2

[0057] In some embodiments of the present disclosure, by setting the first switch to be open and the second switch to be closed in the first working mode, the control system is connected to the external power supply through the second power supply, which can ensure the stability of the performance of the sound system in the first working mode and improve the user experience.

[0058] ​In some embodiments, when the sound system 100 is in the second working mode, the second switch 121 is open, the first switch 111 is closed, and the control system 130 is connected to the external power supply through the first power supply 110.

[0059] In some embodiments, the sound system 100 can be configured to be in the second working mode by default, that is, after the sound system 100 is connected to the external power supply, the control system 130 is connected to the external power supply through the first power supply 120, so that the sound system 100 has higher energy conversion efficiency. In some embodiments, the user can set the sound system to the second working mode, for example, the user can set it through the interaction module; the control system 130 can read the user's settings, control the second switch 121 to be open and the first switch 111 to be closed, so that the control system 130 is connected to the external power supply through the first power supply 110, to meet the user's energy saving requirements for the sound system 100.

[0060] For example, the external power supply is a mains power supply, the sound output is 100W, the efficiency of the first power supply 110 is 92%, and the efficiency of the second power supply 120 is 60%. In this case, the first working mode needs to consume 166.7W of mains power, and the second working mode needs to consume 108.7W of mains power, which is 53.4% less than the first working mode.

[0061] In some embodiments of the present specification, by setting the second switch to be open and the first switch to be closed in the second working mode, the control system is connected to the external power supply through the first power supply, which can reduce the energy consumption of the sound system in the second working mode and achieve energy saving effect.

[0062] In some embodiments of the present specification, by setting the first working mode and the second working mode, the sound system 100 can meet different user needs in different working modes, making the sound system 100 more flexible and improving the user's experience.

[0063] It should be noted that the above description of the sound system 100 and its modules is for convenience of description only, and cannot limit the present specification to the scope of the embodiments. It can be understood that those skilled in the art can combine the modules or connect them to form a subsystem without departing from the principle of the system. In some embodiments, Figure 1 The first power supply 110, the second power supply 120, the control system 130 and the output module 140 disclosed in the present specification can be different modules in a system, or one module can realize the functions of two or more modules. For example, the modules can share a storage module, and the modules can also have their own storage modules. Such variations are within the scope of the present specification.

[0064] Figure 2 is an exemplary schematic diagram of a control system according to some embodiments of the present specification.

[0065] In some embodiments, as shown in Figure 2 the control system 130 can further include a detection module 131 configured to detect the source quality of the audio source to be played by the sound system 100.

[0066] The detection module 131 is a module for detecting the source quality of the audio source. In some embodiments, the detection module 131 is integrated into the control system 130, and can execute a preset instruction of reading the audio file of the audio source and extracting the audio-related information, and take the extracted audio-related information as the source quality of the corresponding audio source.

[0067] For the description of the audio source, please refer to the corresponding description of Figure 1 .

[0068] The source quality is an indicator reflecting the sound quality of the input audio signal of the audio source. For example, the source quality can include the sound quality level, sampling rate, bit depth, etc. of the audio signal. Among them, the sound quality level can include standard sound quality, high-quality sound quality, lossless sound quality, etc. from low to high, different sound quality levels correspond to different code rates, or correspond to different sampling rates, bit depths and channel numbers. For example, the standard sound quality corresponds to an audio with a code rate of 128 kbps, the high-quality sound quality corresponds to an audio with a code rate of 320 kbps, and the lossless sound quality corresponds to a sampling rate of 44.1 kHz-48 kHz, a bit depth of 16 bit, and a channel number of 2.

[0069] In some embodiments, when the sound system 100 is about to play the audio of a certain audio source, the detection module 131 can obtain the audio signal from the audio source and perform detection. For example, the detection module can obtain the audio signal from the audio source through the AUX interface, Bluetooth, HDMI interface, and identify the sound quality level, sampling rate, bit depth, etc. of the audio signal. For example, the identified source quality can be {lossless sound quality, 48 kHz / 16 bit}.

[0070] In some embodiments of the present specification, by setting the detection module in the control system, the source quality of the audio source to be played by the sound system can be detected, which provides a basis for the control system to switch the working mode, so that the control of the control system to the first switch and the second switch is more reasonable.

[0071] Figure 3 is an exemplary schematic diagram of a control system according to some embodiments of the present specification.

[0072] In some embodiments, as shown in Figure 4As shown, when the detection module 131 detects that the sound source quality meets the first preset condition, the control system 130 controls the first switch 111 to be open and the second switch 121 to be closed, so that the sound system 100 switches to the first working mode.

[0073] The first preset condition is a condition for judging whether to switch to the first working mode. In some embodiments, the first preset condition can be that the code rate corresponding to the sound source quality is greater than or equal to 320 kpbs. In some embodiments, the first preset condition can also be that the sound quality level corresponding to the sound source quality is at least high-quality sound quality, for example, high-quality sound quality, lossless sound quality, etc.

[0074] The code rate is an index reflecting the sound quality. The higher the code rate, the better the sound quality. For lossy compressed sound sources (such as.mp3 type audio files), the highest code rate is 320 kpbs. For lossless uncompressed sound sources (such as.wav type audio files), the code rate is the product of the sampling rate, the bit depth, and the number of channels.

[0075] In some embodiments of the present specification, by switching the sound system to the first working mode when the first preset condition is met, the second power supply can be used to power the sound system when the sound source quality of the sound source to be played is high, so that the sound system has better performance indicators, better listening dynamic range, and higher signal-to-noise ratio, and the user's listening experience is improved.

[0076] In some embodiments, as shown, Figure 3 As shown, when the detection module 131 detects that the sound source quality meets the second preset condition, the control system 130 controls the second switch 121 to be open and the first switch 111 to be closed, so that the sound system 100 switches to the second working mode.

[0077] The second preset condition is a condition for judging whether to switch to the second working mode. In some embodiments, the second preset condition can be that the code rate corresponding to the sound source quality is less than 320 kpbs. In some embodiments, the second preset condition can also be that the sound quality level corresponding to the sound source quality is standard sound quality.

[0078] In some embodiments, the sound system 100 has a switching mode, and the sound system 100 can automatically switch between the first working mode and the second working mode in the switching mode; the user can set the sound system 100 to the switching mode through the interaction module, at this time, the detection module 131 performs the above detection work, and the sound system 100 can automatically switch between the first working mode and the second working mode according to whether the sound source quality meets the first preset condition or the second preset condition.

[0079] In some embodiments of the present specification, by switching the sound system to the second working mode when the second preset condition is met, the first power supply can be used to supply power to the sound system when the audio source quality of the audio source to be played is low, which can ensure that the sound system has a certain playing effect, improve energy conversion efficiency, reduce energy loss, and meet the energy-saving needs of users.

[0080] In some embodiments, as shown in Figure 2 The control system 130 further includes an interaction module 132 configured to obtain a user setting and control the opening or closing of the first switch 111 and the second switch 121 based on the user setting.

[0081] The interaction module 132 is a module for interacting with the user. In some embodiments, the interaction module 132 can include a touch screen, a button, a Bluetooth-enabled application, etc.

[0082] The user setting refers to the working mode of the sound system required by the user. For example, the user setting can be that the continuous working time of the sound system in the first working mode is not more than two hours. For another example, the user setting can be that the sound system is switched to the second working mode by default when starting.

[0083] In some embodiments, the interaction module 132 can obtain the user setting through the relevant operation of the user. For example, the user can select a preset working mode on the touch screen or through the button, and the interaction module 132 sets the working mode of the sound system to the working mode selected by the user. For another example, the user can connect to the sound system through the Bluetooth-enabled application and set the working mode, and the interaction module 132 can obtain the setting of the working mode by the user through the Bluetooth-enabled application and set the sound system to the corresponding working mode.

[0084] In some embodiments of the present specification, by setting the interaction module in the control system, obtaining the user setting, and then controlling the opening or closing of the first switch and the second switch, the working mode of the sound system can be better adjusted according to the needs of the user, so that the sound system can be configured to be more personalized, and the overall user experience is improved.

[0085] Figure 4 is an exemplary schematic view of an output module according to some embodiments of the present specification.

[0086] In some embodiments, as shown in Figure 4As shown, the output module 140 can include an amplification device 141 and a speaker device 142; the amplification device 141 is connected with the control system 130, and the speaker device 142 is connected with the amplification device 141; the amplification device 141 is configured to amplify the audio signal, and the speaker device 142 is configured to convert the amplified audio signal into sound output.

[0087] The amplification device 141 is a device for amplifying the audio signal. For example, the amplification device 141 can include a pre-amplifier (Pre-Amp), a power amplifier (Power Amp), etc. The pre-amplifier is used to amplify the weak voltage signal from the sound source to provide a suitable audio level signal, and adjust the sound quality of the equipment. The power amplifier receives the output of the pre-amplifier and further amplifies the output audio signal.

[0088] In some embodiments, the audio signal can be amplified in sequence by the pre-amplifier and the power amplifier.

[0089] In some embodiments, the amplification device 141 can be connected with the control system 130. For example, the pre-amplifier in the amplification device 141 can be electrically connected or communicatively connected with the control system 130, and the power amplifier in the amplification device 141 is electrically connected with the pre-amplifier.

[0090] The speaker device 142 is an electroacoustic transducer device for converting an audio signal into sound. For example, the speaker device 142 can be an electric speaker, a magnetic speaker, etc. In some embodiments, the speaker device 142 is configured to convert the amplified audio signal into sound output.

[0091] In some embodiments, the speaker device 142 is connected with the amplification device 141. For example, the speaker device 142 can be electrically connected with the power amplifier in the amplification device 141.

[0092] In some embodiments of the present specification, by reasonably setting the amplification device and the speaker device, the audio signal can be better amplified so as to be better converted and output, and the sound quality of the sound output by the sound system is ensured.

[0093] The above has described the basic concept, and it is obvious that the above detailed disclosure is only taken as an example and does not constitute a limitation on the present specification. Although it is not explicitly stated here, those skilled in the art can make various modifications, improvements and corrections to the present specification. Such modifications, improvements and corrections are suggested in the present specification, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of the present specification.
