[0054] This application provides a speaker, and the speaker of this application will be described in detail below with reference to the accompanying drawings.

[0055] Reference Figures 1 to 4 The diagram shows a structural schematic of a speaker according to an embodiment of this application. Figure 5 This diagram illustrates the working principle of the speaker provided in this application when used alone. (Refer to...) Figure 6 The diagram illustrates the working principle of the speaker provided in this application when applied to an external audio system.

[0056] like Figures 1 to 5 As shown, this application provides a speaker 100, including: a cabinet 101, a first power amplifier 1024 and at least three speakers; the cabinet 101 is provided with a receiving cavity; the first power amplifier 1024 is disposed in the receiving cavity and includes multiple channels; the speakers are disposed on the cabinet 101 and the frequency ranges of the at least three speakers are different, and one speaker is electrically connected to at least one channel.

[0057] In this embodiment, on the one hand, since at least three speakers with different frequency ranges are provided, sounds of different frequency ranges (i.e., frequency bands) can be played, making the sound received by the user more delicate, comprehensive, and layered, which is beneficial to improving the sound effect of the speaker 100. On the other hand, since the first power amplifier 1024 includes multiple channels, and one speaker is electrically connected to at least one channel, that is, one first power amplifier 1024 can drive at least three speakers to produce sound simultaneously, which can simplify the structure of the speaker 100 and help reduce the production cost of the speaker 100.

[0058] The speaker 100 in this embodiment can be a mono speaker. Specifically, in one embodiment, the first power amplifier 1024 includes a first channel and a second channel; the speaker includes a woofer 103, a midrange speaker, and a tweeter with sequentially increasing frequencies. The midrange speaker and the tweeter are both electrically connected to the first channel, and the woofer 103 is electrically connected to the second channel. In another embodiment, the first power amplifier 1024 includes a first channel, a second channel, and a third channel; the speaker includes a woofer 103, a midrange speaker, and a tweeter with sequentially increasing frequencies. The midrange speaker and the tweeter are both electrically connected to the first channel, and the woofer 103 is electrically connected to both the second channel and the third channel.

[0059] In this embodiment, a woofer 103, a midrange speaker, and a tweeter are provided, with their frequencies increasing sequentially. Specifically, the woofer 103 handles the low-frequency range, the midrange speaker handles the mid-frequency range, and the tweeter handles the high-frequency range. This achieves a three-way stereo effect for the speaker 100, resulting in a more delicate, comprehensive, and layered sound.

[0060] The speaker 100 in this embodiment can also be a two-channel speaker. Specifically, the first power amplifier 1024 includes a first channel, a second channel, a third channel, and a fourth channel; the loudspeakers include a woofer 103, a midrange speaker, and a tweeter with sequentially increasing frequencies. The midrange speaker includes a first midrange speaker 104 and a second midrange speaker 105 with the same frequency range, and the tweeter includes a first tweeter 106 and a second tweeter 107 with the same frequency range. The first midrange speaker 104 and the first tweeter 106 are both electrically connected to the first channel, the woofer 103 is electrically connected to the second channel and the third channel, and the second midrange speaker 105 and the second tweeter 107 are both electrically connected to the fourth channel.

[0061] In this embodiment, a woofer 103, a midrange speaker, and a tweeter are provided, with their frequencies increasing sequentially. Specifically, the woofer 103 handles the low-frequency range, the midrange speaker handles the mid-frequency range, and the tweeter handles the high-frequency range. This achieves a three-way stereo effect for the speaker 100, resulting in a more delicate, comprehensive, and layered sound. Furthermore, since the midrange speaker includes a first midrange speaker 104 and a second midrange speaker 105 with the same frequency range, and the tweeter includes a first tweeter 106 and a second tweeter 107 with the same frequency range, one midrange speaker and one tweeter can be configured for each of the left and right channels. This not only improves the stereo effect but also balances the sound, reduces interference and crosstalk between sounds, further enhancing the sound quality of the speaker 100.

[0062] In practical applications, because the woofer 103 has a lower vibration frequency, a larger amplitude is required to generate sufficient sound pressure. Therefore, the woofer 103 has a higher rated power than the midrange and tweeters. For example, in one embodiment, the woofer 103 has a rated power of 100W, the tweeter has a rated power of 20W, and the midrange speaker has a rated power of 25W. Based on this, by electrically connecting the woofer 103 to two channels (i.e., the second channel and the third channel) of the first power amplifier 1024, the first power amplifier 1024 can reliably drive the woofer 103, which is beneficial for improving the low-frequency extension effect. By electrically connecting the first midrange speaker 104 and the first tweeter 106 to one channel (i.e., the first channel) of the first power amplifier 1024, and electrically connecting the second midrange speaker 105 and the second tweeter 107 to one channel (i.e., the fourth channel) of the first power amplifier 1024, one midrange speaker and one tweeter share one channel. This not only ensures reliable driving of the midrange speaker and the tweeter, but also reduces the number of power amplifiers, which helps to simplify the structure of the speaker 100 and reduce the production cost of the speaker 100.

[0063] It should be noted that the frequency ranges of the sound handled by the tweeter, midrange speaker, and woofer 103 are not limited in this embodiment, and those skilled in the art can make such divisions according to actual needs. In one embodiment, the frequency range of the sound handled by the tweeter is 2kHz to 20kHz; the frequency range of the sound handled by the woofer 103 is 40Hz to 500Hz; and the frequency range of the sound handled by the midrange speaker is between that of the tweeter and the woofer 103. Furthermore, in this embodiment, the first midrange speaker 104 is the midrange speaker corresponding to the left channel, the second midrange speaker 105 is the midrange speaker corresponding to the right channel, the first tweeter 106 is the tweeter corresponding to the left channel, and the second tweeter 107 is the tweeter corresponding to the right channel.

[0064] In some optional embodiments of this application, to further improve the low-frequency extension of the speaker 100, the woofer 103 is a dual voice coil speaker. A dual voice coil speaker can maximize the bass effect within a limited space, realistically reproducing the ultra-low frequency impact during music playback, which is beneficial for improving the stereo effect of the speaker 100.

[0065] In some optional embodiments of this application, the speaker 100 further includes a crossover module 1025, which is disposed between the tweeter and its corresponding channel. The crossover module 1025 is used to process and output audio signals within a first preset frequency range. For a two-channel speaker with five speakers, two crossover modules 1025 are provided, one disposed between the first channel and the first tweeter 106, and the other disposed between the fourth channel and the second tweeter 107.

[0066] In this embodiment of the application, by setting the frequency division module 1025, the audio signal can be processed and the audio signal within the first preset frequency range can be sent to the tweeter, so that the tweeter receives the appropriate audio signal, which can not only avoid sound distortion, but also avoid damage to the tweeter.

[0067] It should be noted that the first preset frequency range in this application embodiment refers to the frequency range corresponding to high-frequency sounds. In one embodiment, the first preset range is 2kHz to 20kHz, meaning the crossover module 1025 can process the received audio signal and output the audio signal of 2kHz to 20kHz to the first tweeter 106 and the second tweeter 107. In one embodiment, the crossover module 1025 is a capacitor. By adjusting the capacitance value of the capacitor, audio signals within the first preset frequency range can pass through, thereby achieving frequency division. On the one hand, capacitors have a simple structure and low cost, which can further simplify the structure of the speaker 100 and reduce the production cost of the speaker 100. On the other hand, the crossover point of this passive crossover method is fixed, requiring no complex adjustments, which is beneficial to further improving the production efficiency of the speaker 100. It is understood that the crossover module 1025 can also be an inductor, resistor, etc., and those skilled in the art can choose according to actual needs.

[0068] In some optional embodiments of this application, the speaker 100 further includes: a first input module 1021 and an audio processing module, wherein the first input module 1021 and the audio processing module are disposed within the receiving cavity; the first input module 1021 is used to output audio signals; the audio processing module is disposed between the first input module 1021 and the first power amplifier 1024, and the audio processing module is used to receive and process audio signals to output left channel audio signals and right channel audio signals.

[0069] In this embodiment, by setting an audio processing module, the audio signal can be processed into a left channel audio signal and a right channel audio signal, thereby enhancing the sound positioning and improving the sound effect of the speaker 100. It should be noted that the first input module 1021 can use BT (Bluetooth) input or USB (Universal Serial Bus) interface input.

[0070] In some optional embodiments of this application, the audio processing module includes: a first audio decoder 1022 and an audio signal processor 1023. The first audio decoder 1022 includes an input terminal, a left channel output terminal, and a right channel output terminal. The audio signal processor 1023 includes a left channel input terminal, a right channel input terminal, a left channel first frequency band output terminal, a left channel second frequency band output segment, a right channel first frequency band output terminal, and a right channel second frequency band output segment. The input terminal is electrically connected to the first input module 1021 and is used to receive audio signals. The left channel output terminal is electrically connected to the left channel input terminal to receive left channel audio signals. The left channel first frequency band output terminal is electrically connected to the first input module 1021. One channel is electrically connected. The left channel second frequency band output terminal is electrically connected to the second channel. The left channel first frequency band output terminal is used to output the left channel audio signal outside the second preset frequency range, and the left channel second frequency band output terminal is used to output the left channel audio signal within the second preset frequency range. The right channel output terminal is electrically connected to the right channel input terminal to receive the right channel audio signal. The right channel first frequency band output terminal is electrically connected to the fourth channel, and the right channel second frequency band output terminal is electrically connected to the third channel. The right channel first frequency band output terminal is used to output the left channel audio signal outside the third preset frequency range, and the right channel second frequency band output terminal is used to output the right channel audio signal within the third preset frequency range.

[0071] In this embodiment, a first audio decoder 1022 and an audio signal processor 1023 are provided. The first audio decoder 1022 can process the received audio signal into a left channel audio signal and a right channel audio signal and output them. The audio signal processor 1023 can process the received left channel audio signal and right channel audio signal into audio signals of different frequency bands. Specifically, by electrically connecting the left channel input terminal and the right channel input terminal of the audio signal processor 1023 to the left channel output terminal and the right channel output terminal of the first audio decoder 1022, respectively, the left channel audio signal and the right channel audio signal output by the audio signal processor 1023 can be received respectively. By electrically connecting the left channel first frequency band output terminal, the left channel second frequency band output terminal, the right channel first frequency band output terminal, and the right channel second frequency band output terminal of the audio signal processor 1023 to the first channel, the second channel, the fourth channel, and the third channel, respectively, audio signals of different frequency bands can be transmitted to different channels of the first power amplifier 1024.

[0072] It should be noted that the second and third preset frequency ranges in this application embodiment refer to the frequency ranges corresponding to low-frequency sounds. In one embodiment, both the second and third preset frequency ranges are 40Hz to 500Hz. That is, the audio signal processor 1023 outputs low-frequency sounds to the second and third channels electrically connected to the woofer 103, and outputs high-frequency sounds, as well as mid-frequency sounds between the low and high frequencies, to the first and / or fourth channels electrically connected to the tweeter and midrange speaker. This allows different speakers to receive compatible audio signals, which is beneficial for improving the sound effect of the speaker 100. In addition, the speaker 100 also includes a circuit board 102. By integrating components such as the first input module 1021, the first audio decoder 1022, the audio signal processor 1023, the first power amplifier 1024, and the crossover module 1025 onto the circuit board 102, not only can the connections between the components be made tighter and the signal transmission more stable and reliable, but the assembly process of the speaker 100 can also be simplified, which is beneficial for improving assembly efficiency.

[0073] In some alternative embodiments of this application, the speaker 100 is applied to a vehicle, which includes an in-vehicle audio system, and the woofer 103 is adapted to be electrically connected to the in-vehicle audio system. Specifically, the in-vehicle audio system includes a second power amplifier 203, and the woofer 103 is adapted to be electrically connected to the second power amplifier 203. In this way, the woofer 103 of the speaker 100 can be reused, which is beneficial to improving the versatility of the speaker 100.

[0074] In some alternative embodiments of this application, the vehicle includes a body, and the speaker 100 is adapted to be detachably connected to the body (such as the interior side panel, armrest, dashboard, etc.) to facilitate the removal and installation of the speaker 100, thereby enabling the speaker 100 to be used independently and reused with the vehicle audio system.

[0075] When the speaker 100 is a mono speaker, that is, when the speaker 100 includes three speakers, the enclosure 101 includes a panel 1012, the panel 1012 includes a central area and four corner areas located around the central area, the woofer 103 is disposed in the central area, and the midrange speaker and the tweeter are disposed in two of the corner areas.

[0076] In this embodiment, since the woofer 103, midrange speaker, and tweeter are all located on the panel 1012, the sound played by the speaker 100 is more balanced and harmonious. Furthermore, because low-frequency sounds have longer wavelengths, the woofer 103 is larger than the midrange and tweeters. By placing the larger woofer 103 in the middle area and the smaller midrange and tweeters in the two corner areas, the space of the panel 1012 can be utilized efficiently, which is beneficial for the miniaturization of the speaker 100.

[0077] When the speaker 100 is a two-channel speaker, that is, when the speaker 100 includes five speakers, the enclosure 101 includes: a frame 1011, a front panel 1012 and a bottom plate 1013. The frame 1011 is disposed between the front panel 1012 and the bottom plate 1013 and surrounds the front panel 1012 and the bottom plate 1013 to form a receiving cavity. The front panel 1012 includes a central area and four corner areas around the central area. The woofer 103 is disposed in the central area, and the first midrange speaker 104, the second midrange speaker 105, the first tweeter 106 and the second tweeter 107 are respectively disposed in the four corner areas.

[0078] In this embodiment, since the woofer 103, midrange speakers (including the first midrange speaker 104 and the second midrange speaker 105), and tweeters (including the first tweeter 106 and the second tweeter 107) are all located on the panel 1012, the sound played by the speaker 100 can be more balanced and harmonious. Furthermore, because low-frequency sounds have longer wavelengths, the woofer 103 is larger in size than the midrange and tweeters. By placing the larger woofer 103 in the middle area and the smaller midrange speakers (including the first midrange speaker 104 and the second midrange speaker 105) and tweeters (including the first tweeter 106 and the second tweeter 107) in the four corner areas, the space of the panel 1012 can be utilized efficiently, which is beneficial for the miniaturization design of the speaker 100.

[0079] It should be noted that, as Figure 2 As shown, when the panel 1012 is square, the panel 1012 has four corners. The middle area refers to the area near the center of the panel 1012, and the corner area refers to the area near the corner of the panel 1012.

[0080] In some optional embodiments of this application, the apex region includes: a first apex region, a second apex region, a third apex region, and a fourth apex region arranged sequentially along the circumference of the panel 1012; a first tweeter 106 is disposed in the first apex region, a second tweeter 107 is disposed in the second apex region, a first midrange speaker 104 is disposed in the third apex region, and a second midrange speaker 105 is disposed in the fourth apex region. That is, the two midrange speakers (i.e., the first midrange speaker 104 and the second midrange speaker 105) are disposed in two adjacent apex regions, and the two tweeters (i.e., the first tweeter 106 and the second tweeter 107) are also disposed in two adjacent apex regions. In this way, for midrange and tweeters of different sizes, the size of the panel 1012 can be further reduced through reasonable arrangement, which is beneficial to the miniaturization design of the speaker 100.

[0081] It should be noted that the connection method between the speaker and the panel 1012 is not limited in this application embodiment. In one embodiment, taking the woofer 103 as an example, a mounting hole is provided in the middle area of ​​the panel 1012. The woofer 103 is embedded in the mounting hole and fixed to the panel 1012 with screws to achieve a reliable connection between the woofer 103 and the panel 1012. The connection methods of the first midrange speaker 104, the second midrange speaker 105, the first tweeter 106, and the second tweeter 107 are similar and will not be described in detail here.

[0082] In some optional embodiments of this application, the enclosure 101 further includes: a first partition 1014 and a second partition 1015, the first partition 1014 and the second partition 1015 being spaced apart within the receiving cavity, with the first partition 1014 corresponding to the first midrange speaker 104 and the second partition 1015 corresponding to the second midrange speaker 105; the first partition 1014, the frame 1011 and the panel 1012 enclose a first chamber 1016, the first chamber 1016 being connected to the first midrange speaker 104; the second partition 1015, the frame 1011 and the panel 1012 enclose a second chamber 1017, the second chamber 1017 being connected to the second midrange speaker 105; the first partition 1014, the second partition 1015, the frame 1011, the panel 1012 and the bottom plate 1013 enclose a third chamber 1018, the third chamber 1018 being connected to the woofer 103. In this way, the first chamber 1016 can serve as the rear chamber of the first midrange speaker 104, the second chamber 1017 can serve as the rear chamber of the second midrange speaker 105, and the third chamber 1018 can serve as the rear chamber of the woofer 103. This provides a better acoustic environment for the midrange speakers (including the first midrange speaker 104 and the second midrange speaker 105) and the woofer 103, reduces sound reflection and interference inside the speaker enclosure 100, and helps to further improve the sound effect of the speaker enclosure 100.

[0083] In some optional embodiments of this application, the speaker 100 further includes an electrical connector 1019, which is disposed on the enclosure 101 and is used to electrically connect with an external audio system 200 to realize the transmission of audio signals and / or electrical energy.

[0084] In this embodiment of the application, since an electrical connector 1019 is provided, by electrically connecting the electrical connector 1019 to an external audio system 200 (such as a vehicle audio system 200), the transmission of audio signals and / or electrical energy can be realized, thereby enabling the reuse and charging of the speaker 100.

[0085] Specifically, the electrical connector 1019 includes an audio signal terminal electrically connected to the woofer 103. When the electrical connector 1019 is electrically connected to an external audio system 200, the audio signal terminal is electrically connected to the second power amplifier 203 of the audio system 200, thereby enabling the reuse of the woofer 103 in the speaker 100 and eliminating the need for the woofer 103 in the external audio system 200. Furthermore, the speaker 100 also includes a power module, and the electrical connector 1019 includes a power terminal electrically connected to the power module. When the electrical connector 1019 is electrically connected to the external audio system 200, the power supply of the audio system 200 can transfer electrical energy to the power module of the speaker 100, thereby charging the speaker 100.

[0086] In summary, the speaker provided in this application embodiment has at least the following advantages:

[0087] In this embodiment, on the one hand, since at least three speakers with different frequency ranges are provided, sounds from different frequency ranges (i.e., frequency bands) can be played, making the sound received by the user more delicate, comprehensive, and layered, which is beneficial to improving the sound effect of the speaker. On the other hand, since the first power amplifier includes multiple channels, and one speaker is electrically connected to at least one channel, that is, one first power amplifier can drive at least three speakers to produce sound simultaneously, which can simplify the structure of the speaker and help reduce the production cost of the speaker.

[0088] This application also provides an audio system 200, including the speaker 100 described above.

[0089] Specifically, such as Figure 6 As shown, the audio system 200 includes a second input module 201, a second audio decoder 202, a second power amplifier 203, and multiple speakers, all electrically connected in sequence. The second input module 201 outputs audio signals, the second audio decoder 202 processes the audio signals into different audio signals and outputs them to the second power amplifier 203, which drives the speakers to produce sound. The subwoofer 103 of the speaker 100 is electrically connected to two channels of the second power amplifier 203. This allows the subwoofer 103 of the speaker 100 to participate in the music playback of the audio system 200, enhancing the ultra-low frequency listening experience. Furthermore, it eliminates the need for the built-in subwoofer 103 in the audio system 200, further reducing its cost. In one embodiment, the second audio decoder 202 and the second power amplifier 203 use an A2B (Automotive Audio Bus) for transmission, further reducing the weight and cost of the wiring harness in the audio system.

[0090] It should be noted that in this embodiment, the structure of the speaker 100 is the same as that of the speaker 100 in any of the above embodiments, and its beneficial effects are also similar, so it will not be described in detail here. Furthermore, the audio system 200 of this application can be widely used in various application scenarios such as vehicles, cinemas, and outdoor stages.

[0091] This application also provides a vehicle, including the speaker 100 described above, or the audio system 200 described above.

[0092] It should be noted that in this embodiment, the structure of the audio system 200 is the same as that of the audio system 200 in any of the above embodiments, and its beneficial effects are also similar, so it will not be described in detail here.
