[0002] At present, in the TV panel market, manufacturers generally pursue thin and light TV panels, which makes the overall size of the TV small and thin. The equipment has no space to place large-size speakers, and the subwoofer is relatively large due to its composition structure and internal principle. Therefore, the sound quality of the TV cannot meet people's demand for better sound quality. It is usually necessary to cooperate with external speakers to complete the playback of stereo surround sound. The sound quality of the TV is generally improved by the combination of soundbar and subwoofer. However, this combination has the disadvantages of complex connection, poor stereo effect of linear arrangement of soundbar speakers, and ineffective use of the TV's own speaker resources. The overall effect cannot meet the user's usage needs. Professional stereo surround speakers are expensive and have strict requirements on the connection settings, space requirements, placement of speakers, and power supply of speakers. They are difficult to promote in the general consumer market and cannot meet the sound quality needs of more users. In addition, TVs on the market generally have technical problems such as not supporting karaoke or poor karaoke sound quality, and large delay of external speakers, which cannot meet the needs of users in multiple scenarios.

[0052] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0054] In one embodiment, the reference specification Figure 1 The present application provides a stereo surround sound karaoke system, comprising: an audio transceiver 10, a media player 20 connected to the audio transceiver 10, a plurality of speakers and a plurality of integrated microphones 40;
[0055] Specifically, the audio transceiver 10 is a device that can be detachably connected to the media player 20 to receive and send audio and also undertake the mixing function of part of the system. It can be connected to the media player 20 as an independent device, or it can be set in the media player 20 when the media player 20 is manufactured. The media player 20 includes electronic devices such as televisions, computers, and projectors that have multimedia functions such as video and audio. It is a visual media device that meets human audio and video entertainment. The audio transceiver 10 and the media player 20 can be wirelessly connected through wireless communication protocols such as Bluetooth, or mechanically connected through a physical interface in accordance with an interface protocol.
[0056] The phono-amplifier integrated microphone 40 is used to pick up the human voice signal S1 and send the human voice signal S1 to the audio transceiver 10;
[0057] Specifically, the phono-amplifier microphone 40 is a media device that integrates the vocal pickup function of a microphone and the audio playback function of a speaker. The phono-amplifier microphone 40 picks up the vocals when the user speaks, converts it into a vocal signal S1, and then sends it to the audio transceiver 10, where its microphone function is used for sound pickup.
[0058] The audio transceiver 10 is used to send the human voice signal S1 to the media player 20;
[0059] Specifically, the audio transceiver 10 serves as a medium between the media player 20 and the phono-amplifier microphone 40 , transmitting the human voice signal S1 to the media player 20 , in preparation for subsequent mixing and playback processes.
[0060] The media player 20 is used to mix the accompaniment audio signal S2 and the vocal signal S1 to generate a first mixed audio signal, and play the first mixed audio signal through a speaker of the media player 20;
[0061] Specifically, the media player 20 with an audio input function can receive an externally input human voice signal S1, mix its own stored audio, and play it through the built-in speaker of the media player 20. In this embodiment, the media player 20 receives the human voice signal S1 picked up by the phono-amplifier integrated microphone 40, mixes it with the accompaniment audio signal S2 and plays it. The accompaniment audio signal S2 comes from an audio file stored in the media player 20 or obtained online to realize the karaoke function. For example, a karaoke application is installed in the media player 20, and the audio accompaniment can be directly downloaded for karaoke when the application is running.
[0062] At the same time, after the media player 20 generates the first mixed audio signal, it performs frequency division processing on it, sends the low-frequency mixed audio signal to the low-frequency speaker 22 or the passive radiator for playback, and sends the mid-high frequency mixed audio signal to the mid-high frequency speaker 23 for playback, thereby realizing a combination of different sound levels. At the same time, when the media player 20 has multiple low-frequency speakers 22 and multiple mid-high frequency speakers 23, the audio played in speakers at different frequency bands and different positions can realize spatial surround sound of the left and right channels, improve the overall sound effect, and enhance the user's karaoke experience.
[0063] The media player 20 is also used to send the accompaniment audio signal S2 to the audio transceiver 10;
[0064] The media player 20 has an audio output function. The traditional output function is usually that the media player 20 sends the acquired sound through an external speaker or the like. The process of sending the accompaniment audio signal S2 to the audio transceiver 10 in the present application is similar to the above process, which is the process of transmitting the accompaniment audio signal S2 outward, which can be either wireless transmission or wired transmission.
[0065] The audio transceiver 10 is also used to mix the accompaniment audio signal S2 and the vocal signal S1 to generate a second mixed audio signal, and send the second mixed audio signal to a plurality of speakers for playback;
[0066] Specifically, the speakers usually do not have a mixing function, and the human voice signal S1 and the accompaniment audio signal S2 need to be mixed in advance by the audio transceiver 10, and the second mixed audio signal is generated and then played through the external speakers. When there are more than two speakers, the audio transceiver 10 divides the mixed audio signal according to different frequencies when sending the mixed sound, and sends the mixed audio signals of different frequencies to the corresponding speakers at the same time, and realizes the stereo surround sound of the overall speaker layout by reasonably setting the position of the speakers.
[0067] The audio transceiver 10 is also used to send the accompaniment audio signal S2 to a plurality of phono-amplifier integrated microphones 40;
[0068] The phono-amplifier microphone 40 is also used to mix the accompaniment audio signal S2 and the vocal signal S1 to generate a third mixed audio signal. After the third mixed audio signal is divided, it is played through the speaker of the phono-amplifier microphone 40.
[0069] Specifically, the phono-amplifier microphone 40 needs to have accompaniment audio to realize the karaoke function. The accompaniment audio signal S2 generated by the media player 20 is transmitted to the phono-amplifier microphone 40 through the audio transceiver 10 as a medium. The phono-amplifier microphone 40 has a mixing function, which can mix the human voice signal S1 picked up and the received accompaniment audio, and play it through its own microphone. When there are more than two phono-amplifier microphones 40, the phono-amplifier microphones 40 can be used as part of a stereo surround sound system by setting channels, and a stereo surround effect can be achieved through reasonable layout.
[0070] In one embodiment, the reference specification Figure 2 After the stereo surround sound karaoke system is started, the human voice signal S1 is picked up by at least one phono-amplifier integrated microphone 40, and the picked up human voice signal S1 is given to the audio transceiver 10. The audio transceiver 10 transmits the human voice signal S1 to the media playback device 20. The media playback device 20 combines the accompaniment audio signal S2, mixes it with the human voice signal S1, and generates a first mixed audio signal.
[0071] In one implementation, refer to the attached specification Figure 2 , a stereo surround sound karaoke system, the media playback device 20 also includes: a plurality of low-frequency speakers 22 and a plurality of mid- and high-frequency speakers 23;
[0072] The media playback device 20 is further configured to divide the first mixed audio signal into a first low-frequency mixed audio signal S3 and a first medium- and high-frequency mixed audio signal S4;
[0073] The low-frequency speaker 22 is used for playing the first low-frequency mixed audio according to the first low-frequency mixed audio signal S3 generated by the frequency division of the media playing device 20;
[0074] The mid-high frequency speaker 23 is used for playing the first mid-high frequency mixed audio according to the first mid-high frequency mixed audio signal S4 generated by the frequency division of the media playing device 20 .
[0075] Specifically, the playback system inside the media playback device 20 is a combination of a low-frequency speaker 22 (or a passive radiator) and a mid-to-high frequency speaker 23. In order to achieve stereo surround sound with sound layers, they are also symmetrically arranged. For example, the media playback device 20 has 2N low-frequency speakers 22, and N low-frequency speakers 22 are symmetrically arranged on the left and right. Correspondingly, it has 2N mid-to-high frequency speakers 23, and N mid-to-high frequency speakers 23 are symmetrically arranged on the left and right. The sound processor 21 in the media playback device 20 performs frequency division. During playback, the first low-frequency mixed audio and the first mid-to-high frequency mixed audio of the corresponding frequency are played in the corresponding speakers to achieve layered, stereo surround sound, thereby improving the overall sound quality.
[0076] In one implementation, a stereo surround sound karaoke system, a plurality of speakers include at least one subwoofer 31;
[0077] The audio transceiver 10 is further used for dividing the second mixed audio signal into a second low-frequency mixed audio signal S5, and sending the second low-frequency mixed audio signal to the subwoofer 31 for playing.
[0078] Specifically, there are some subwoofers 31 among the multiple speakers, which are used to enhance the atmosphere during music playing and highlight the rhythm of the music. The low-frequency part of the second mixed audio signal needs to be divided by the audio transceiver 10 and sent to the subwoofer 31 as the second low-frequency mixed audio signal S5 for playing.
[0079] In one implementation, a stereo surround sound karaoke system, a plurality of phono-amplifier integrated microphones 40 include a left channel phono-amplifier integrated microphone 40 and a right channel phono-amplifier integrated microphone 40;
[0080] After the left-channel phono-amplifier integrated microphone 40 divides the third mixed audio signal, the third mixed audio is played through the left-channel speaker of the left-channel phono-amplifier integrated microphone 40;
[0081] After the right-channel phono-amplifier integrated microphone 40 divides the frequency of the third mixed audio signal, the third mixed audio is played through the right-channel speaker of the right-channel phono-amplifier integrated microphone 40 .
[0082] Specifically, when there are multiple phono-amplifier microphones 40 in a stereo surround sound karaoke system, the sound spatial sense of the stereo surround sound karaoke system is further increased by dividing the left and right channels of the speakers carried by the phono-amplifier microphones 40, and the multiple phono-amplifier microphones 40 are divided into a left channel and a right channel, and then the third mixed audio is played correspondingly on the left channel phono-amplifier microphone 40 or the right channel phono-amplifier microphone 40, thereby further increasing the surround effect of the overall system.
[0083] In one implementation, a stereo surround sound karaoke system, the audio transceiver 10 and the media player 20 are detachably connected.
[0084] or,
[0085] The audio transceiver 10 is disposed in the media playing device 20 .
[0086] Specifically, the media player 20 usually does not have the audio media and mixing functions of the audio transceiver 10, and needs to be set up outside it. There are two setting methods. One is that the audio transceiver 10 is connected to the media player 20 by wire, and is connected through a USB or other type of data transmission port to achieve the transmission of the human voice signal and the accompaniment audio signal. At the same time, the media player 20 can power the audio transceiver 10 through the interface. The other is wireless transmission. The audio transceiver 10 is wirelessly connected to the media player 20 through a wireless communication protocol such as Bluetooth and other wireless transmission methods, which can make the placement of the audio transceiver 10 more flexible and improve the user experience.
[0087] In one implementation, a stereo surround sound karaoke system, a plurality of speakers are connected to an audio transceiver 10,
[0088] or,
[0089] A plurality of speakers are connected to the audio transceiver 10 via wires.
[0090] Specifically, the audio transceiver 10 can be connected to several speakers via wires, and the audio signal is transmitted through the audio transmission interface. The wired transmission method has the characteristics of stable transmission path and strong anti-interference ability. At the same time, the audio transceiver 10 can be connected to several speakers wirelessly, and a signal transmission path is established through a wireless communication protocol, making the setting of the speakers more flexible, more in line with the mainstream Bluetooth speakers on the market, avoiding interface restrictions, and facilitating connection.
[0091] In one implementation, a stereo surround sound karaoke system, a plurality of integrated microphones 40 are wirelessly connected to an audio transceiver 10,
[0092] or,
[0093] A plurality of integrated phono microphones 40 are connected to the audio transceiver 10 via wires.
[0094] Specifically, the phono-amplifier microphone 40 can be wirelessly connected to the audio transceiver 10 to receive and send audio data through a wireless communication protocol. When the user uses the wirelessly connected phono-amplifier microphone 40, it is not restricted by space, is more flexible, and provides a better karaoke experience. On the other hand, the phono-amplifier microphone 40 can be wired to the audio transceiver 10 to establish wired signal transmission, improve overall anti-interference capabilities, and can be powered by a wired connection to improve battery life.
[0095] Based on the same technical concept, the present application provides an audio transceiver 10, including:
[0096] The first communication module 100 is used to receive a human voice signal sent by an external microphone 1 and send the human voice signal to an external media device 2;
[0097] The second communication module 200 is used to receive the accompaniment audio signal sent by the external media device 2;
[0098] The mixer 300 is used to mix the vocal signal and the accompaniment audio signal to generate a mixed audio signal;
[0099] The frequency divider 400 is used to divide the frequency of the mixed audio signal;
[0100] The third communication module 500 is used to send the divided mixed audio signal to the playback device 3 of the corresponding frequency.
[0101] Specifically, the audio transceiver 10 is an audio signal processing medium for communicating with the external media device 2, the external microphone 1 and the playback device 3. The human voice signal picked up by the external microphone 1 is received from the external microphone 1 through the first communication module 100, and the human voice signal is sent to the external media device 2, so as to realize the receiving process of the microphone pickup by the media device that cannot be directly connected to the microphone, so as to achieve that the TV, computer or projector and other devices without karaoke function can input the human voice audio through the microphone and play the human voice audio. The second communication module 200 is used to receive the accompaniment audio signal from the external media device 2. The external media device 2 stores or can download the accompaniment audio signal online. After being obtained by the second communication module 200, it can be further given to the external phono-integrated microphone or audio equipment for mixing and other operations, so as to realize the signal interaction of the accompaniment audio. The mixer 300 mixes the human voice signal obtained by the first communication module 100 and the accompaniment audio signal obtained by the second communication module 200, so that the human voice and the accompaniment can be effectively combined, and the playback is smooth, and the sound effect is improved. The function of the divider 400 is to divide the mixed audio signal according to its frequency, so that the divided mixed audio signal can be played on the playback device 3 that plays different frequencies through the third communication module 500. When the external audio has a distinction between left and right channels or low, medium and high frequencies, a more layered stereo surround sound can be achieved.
[0102] In one implementation, an audio transceiver 10 , the second communication module 200 , is further configured to send the accompaniment audio signal to an external media playback device 20 .
[0103] Among the devices connected to the audio transceiver 10, there are also devices that have both sound pickup and playback functions, such as a phono-amplifier microphone. The phono-amplifier microphone itself can mix and divide the accompaniment audio signal and the human voice audio signal, and thus send the accompaniment audio signal to the external media device 2, so that its own mixing produces audio that is more in line with its characteristics, thereby improving the user's karaoke experience and sound effects.
[0104] Based on the same technical concept, the present application provides a media device, including an audio transceiver in any of the above embodiments.
[0105] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
