Description

Technical Field

[0001] The present invention relates to the technical field of intelligent automobiles, and in particular to a karaoke system, a karaoke method and an automobile. Background Art

[0002] In the past, the entertainment methods in cars were relatively simple. People in the car sat in a fixed position for a long time and passively received information, which was not only boring but also prone to fatigue.

[0003] Therefore, in order to eliminate the fatigue of the occupants during driving and improve the entertainment of the journey, the entertainment systems in cars are becoming more and more abundant. For example, the entertainment systems currently equipped in cars are developing towards multi-functions, bringing as many entertainment functions that can be achieved at home into the car as possible.

[0004] For example, the in-car karaoke system came into being, which has a singing function to facilitate people in the car to sing karaoke in the car.

[0005] However, in actual use, users often do not always stay in the car to sing karaoke. For example, when using the in-car karaoke system outdoors, users may carry a microphone outside the car to sing karaoke.

[0006] However, when a user carries a microphone to sing karaoke outside the car, the volume of the karaoke played by the in-car speakers heard by the user is often not loud enough to meet the user's demand for a high volume when singing karaoke outside the car.

[0007] To this end, a Bluetooth speaker can be added outside the car. In this way, when the user carries a microphone to sing karaoke outside the car, the Bluetooth speaker outside the car can play the sound of the user's karaoke. The user can place the Bluetooth speaker next to the user so that the volume of the Bluetooth speaker heard by the user is loud enough to meet the user's auditory needs for high volume when singing karaoke outside the car.

[0008] However, the inventor found that after adding a Bluetooth speaker outside the car, the sounds played by the car speaker and the Bluetooth speaker are not synchronized, which causes the user to hear sounds played by the car speaker and the Bluetooth speaker are not synchronized, which undoubtedly reduces the user's experience of singing karaoke outside the car.

[0177] At least one additional speaker receives the mixed audio data broadcast by the portable speaker at a uniform frequency.

[0178] It can be seen that in the present invention, the portable speaker is directly connected to each additional speaker based on a specific frequency.

[0179] The direct communication connection can be understood as: the portable speaker can transmit data to each additional speaker without being transferred through a third device.

[0180] The specific frequency and the uniform frequency may be different frequencies.

[0181] In summary, in the present invention, the karaoke microphone and the vehicle-mounted host can be directly connected via FM communication of the same frequency. The karaoke microphone and the portable speaker can be directly connected via FM communication of the same frequency. The portable speaker and each additional speaker can be directly connected via FM communication of the same frequency.

[0182] The "FM frequency between the karaoke microphone and the portable speaker" and the "FM frequency between the karaoke microphone and the car host" are the same frequency.

[0183] The “FM frequency between the karaoke microphone and the portable speaker” and the “FM frequency between the portable speaker and each additional speaker” are different frequencies.

[0184] In another embodiment of the present invention, in the case where the karaoke system has a karaoke receiver, the karaoke receiver may be a universal serial bus (USB) receiver, and the karaoke receiver may be plugged into a USB port on the vehicle-mounted host. In one example, the USB receiver may be a USB dongle receiver.

[0185] Alternatively, the karaoke receiver can also be fixed on the vehicle-mounted host as a module with wireless communication function of the vehicle-mounted host.

[0189] For WiFi connection, you can turn on the power of the portable speaker, pair the portable speaker with the karaoke receiver via WiFi, and the portable speaker and the karaoke receiver will complete the communication connection and can directly exchange data.

[0190] The vehicle host may have an operating system, and a third-party karaoke APP may run in the operating system, so that users can use the third-party karaoke APP to sing karaoke. Alternatively, the operating system may also have its own karaoke applet, so that users can use the karaoke applet to sing karaoke.

[0191] The karaoke applet can be equivalent to a mixing console, and users can adjust the system volume and sound effects of the operating system on the in-car display (for example, the display corresponding to the car host).

[0192] The karaoke applet that comes with the operating system can be implanted into the operating system by the developer of the operating system.

[0193] The karaoke microphone can send the vocal data collected by the karaoke microphone to the vehicle host. In this way, the vehicle host can receive the vocal data collected by the karaoke microphone, and the vehicle host can mix the karaoke accompaniment data and the vocal data obtained by the vehicle host to obtain mixed data; and play the mixed data through the in-vehicle speakers.

[0194] Among them, the in-car speaker includes: an in-car power amplifier and an in-car speaker.

[0195] In this way, the vehicle host can amplify the mixed data through the in-vehicle power amplifier and output it to the in-vehicle speakers to drive the in-vehicle speakers to make sound, so as to play the mixed data.

[0196] The in-car power amplifier, referred to as the power amplifier, refers to a basic device in the speaker system. Its task is to amplify the incoming sound data to drive the speaker to make sound.

[0197] The vehicle host can be connected to the A2B module of the in-vehicle power amplifier via the A2B bus, thereby realizing the connection between the vehicle host and the in-vehicle power amplifier.

[0198] In-car speakers are speakers installed inside the vehicle, generally used for playing music, karaoke, speeches or hosting, etc.

[0199] In the present invention, the vehicle-mounted host can obtain the local karaoke accompaniment data of the vehicle-mounted host, or the vehicle-mounted host can also communicate with other devices (such as mobile phones or tablet computers, etc.) (WiFi connection or Bluetooth connection, etc.), so that the vehicle-mounted host can also obtain the karaoke accompaniment data in other devices.

[0200] In one embodiment, when the karaoke mode of the karaoke system is a synchronous karaoke mode inside and outside the car, the vehicle host is used to obtain karaoke accompaniment data; the portable speaker is used to obtain karaoke accompaniment data; the karaoke microphone is used to collect vocal data; the karaoke microphone is also used to directly send vocal data to the portable speaker, and the karaoke microphone is also used to send vocal data to the vehicle host; the vehicle host is also used to mix the karaoke accompaniment data and the vocal data to obtain mixed data; the portable speaker is also used to mix the karaoke accompaniment data and the vocal data to obtain mixed data; the vehicle host is also used to play the mixed data through the in-vehicle speaker; the portable speaker is also used to play the mixed data.

[0201] For example, the vehicle-mounted host is used to obtain karaoke accompaniment data; the karaoke microphone is used to collect vocal data.

[0202] The vehicle-mounted host is also used to send karaoke accompaniment data to the portable speaker; the karaoke microphone is also used to directly send vocal data to the portable speaker, and the karaoke microphone is also used to send vocal data to the vehicle-mounted host.

[0204] The vehicle-mounted host is also used to play the mixed sound data through the in-vehicle speakers; the portable speakers are also used to play the mixed sound data.

[0205] Among them, the action of the vehicle-mounted host obtaining the karaoke accompaniment data and the action of the karaoke microphone collecting the vocal data can be executed synchronously.

[0206] The action of the vehicle-mounted host sending karaoke accompaniment data to the portable speaker, the action of the karaoke microphone directly sending vocal data to the portable speaker, and the action of the karaoke microphone sending vocal data to the vehicle-mounted host can be performed synchronously.

[0207] The action of the vehicle-mounted host mixing the karaoke accompaniment data and the vocal data to obtain the mixed data, and the action of the portable speaker mixing the karaoke accompaniment data and the vocal data to obtain the mixed data can be performed synchronously.

[0208] The action of the vehicle host playing the mixed sound data through the in-vehicle speakers and the action of the portable speakers playing the mixed sound data can be performed synchronously.

[0209] The karaoke accompaniment data obtained by the vehicle host may be the karaoke accompaniment data stored locally in the vehicle host, or the karaoke accompaniment data in other devices (such as mobile phones or tablet computers, etc.) that are connected to the vehicle host for communication, or the online karaoke accompaniment data obtained from the network in real time.

[0210] The synchronous karaoke mode inside and outside the car can be understood as: the car speaker is located inside the car, and the portable speaker is located outside the car. The portable speaker and the car speaker play the same mixed data synchronously, so that people inside and outside the car can hear the same mixed data at the same time, thereby realizing synchronous karaoke inside and outside the car.

[0211] Alternatively, in another embodiment, the karaoke microphone is directly communicated with the in-car speaker; when the karaoke mode of the karaoke system is the synchronous karaoke mode inside and outside the car, the in-car speaker is used to obtain karaoke accompaniment data; the portable speaker is used to obtain karaoke accompaniment data; the karaoke microphone is used to collect vocal data; the karaoke microphone is also used to directly send vocal data to the portable speaker, and the karaoke microphone is also used to directly send vocal data to the in-car speaker; the in-car speaker is also used to mix the karaoke accompaniment data and the vocal data to obtain mixed data; the portable speaker is also used to mix the karaoke accompaniment data and the vocal data to obtain mixed data; the in-car speaker is also used to play the mixed data; the portable speaker is also used to play the mixed data.

[0212] It should be noted that the synchronous karaoke mode inside and outside the car does not limit the number of karaoke microphones. It can be one or more. For example, there can be a karaoke microphone inside the car but not outside the car, there can be a karaoke microphone outside the car but not inside the car, or there can be karaoke microphones both inside and outside the car.

[0213] Or, in another embodiment, Figure 1 or Figure 2 In the karaoke system shown, when the karaoke mode of the karaoke system is switched to the out-of-car karaoke mode, the karaoke microphone is also used to collect vocal data, and the portable speaker is also used to obtain karaoke accompaniment data.

[0214] The karaoke microphone is also used to send vocal data directly to portable speakers.

[0215] The portable speaker is also used for mixing the karaoke accompaniment data and the vocal data to obtain the first mixed data.

[0216] The portable speaker is also used to play the mixed audio data.

[0217] The action of the karaoke microphone collecting vocal data and the action of the portable speaker collecting song accompaniment data can be performed synchronously.

[0218] The karaoke accompaniment data obtained by the portable speaker can be the karaoke accompaniment data stored locally in the portable speaker, or the karaoke accompaniment data in other devices (such as mobile phones or tablet computers, etc.) that are communicatively connected to the portable speaker, or the online karaoke accompaniment data obtained from the network in real time.

[0219] The out-of-car karaoke mode can be understood as: the karaoke microphone can be located outside the car, the user is also located outside the car, and the portable speaker is located outside the car. The vocal data (of the user outside the car) collected by the karaoke microphone may not be sent to the in-car host, and the in-car host may not play the mixed data obtained by the vocal data collected by the karaoke microphone through the in-car speakers. The vocal data (of the user outside the car) collected by the karaoke microphone is sent to the portable speaker, and the portable speaker can play the mixed data obtained by the vocal data collected by the karaoke microphone. This ensures that people in the car will not hear the mixed data through the in-car speakers, and people outside the car can hear the mixed data through the portable speakers, thereby realizing out-of-car karaoke.

[0220] In the out-of-car karaoke mode, the karaoke microphone and the car host can be directly communicated and connected, or the karaoke microphone can be communicated and connected to the car host via a karaoke receiver.

[0221] Further, based on this embodiment, in another embodiment, Figure 1 Based on the karaoke system shown, see Figure 3 There are multiple karaoke microphones in the karaoke system (it should be noted that Figure 2 Based on the karaoke system shown, there may be multiple karaoke microphones in the karaoke system, which are not shown in the figure and are not described in detail).

[0222] When the karaoke mode of the karaoke system is switched to the separate inside-outside-car karaoke mode, the first karaoke microphone among the multiple karaoke microphones is used to collect the first vocal data and directly send the first vocal data to the portable speaker; the portable speaker is also used to obtain the first karaoke accompaniment data, mix the first karaoke accompaniment data and the first vocal data to obtain the first mixed data, and play the first mixed data.

[0223] The action of the first karaoke microphone collecting the first vocal data and the action of the portable speaker acquiring the first karaoke accompaniment data can be performed synchronously.

[0224] On the other hand, the second karaoke microphone among the multiple karaoke microphones is used to collect second vocal data and send the second vocal data to the vehicle-mounted host; the vehicle-mounted host is also used to obtain second karaoke accompaniment data, mix the second karaoke accompaniment data and the second vocal data to obtain second mixed data; and play the second mixed data through the in-vehicle speakers.

[0225] The action of the second karaoke microphone collecting the second vocal data and the action of the vehicle-mounted host obtaining the second karaoke accompaniment data can be performed simultaneously.

[0226] The first karaoke accompaniment data obtained by the portable speaker may be karaoke accompaniment data stored locally in the portable speaker, or karaoke accompaniment data in other devices (such as a mobile phone or tablet computer, etc.) that are communicatively connected to the portable speaker, or online karaoke accompaniment data obtained from the network in real time.

[0227] The second karaoke accompaniment data obtained by the vehicle host may be karaoke accompaniment data stored locally in the vehicle host, or karaoke accompaniment data in other devices (such as mobile phones or tablet computers, etc.) that are communicatively connected to the vehicle host, or online karaoke accompaniment data obtained from the network in real time.

[0228] When the karaoke mode of the karaoke system is switched to the separate inside-outside-car karaoke mode, the second karaoke accompaniment data obtained by the vehicle host and the first karaoke accompaniment data obtained by the portable speaker can be the same accompaniment data or different accompaniment data.

[0229] It should be noted that in the separate karaoke modes inside and outside the car, there is a karaoke microphone inside the car and a karaoke microphone outside the car.

[0230] The separate karaoke mode for inside and outside the car can be understood as: the car speaker is located inside the car, the portable speaker is located outside the car, and the portable speaker and the car speaker play different mixed sound data respectively, so that the mixed sound data heard by the person inside the car and the person outside the car can be different. The karaoke inside the car and the karaoke outside the car can be independent of each other.

[0231] The karaoke microphone in the car collects vocal data 1 of user 1 in the car, and the microphone in the car sends the vocal data 1 to the car host. The car host obtains the karaoke accompaniment data 1, mixes the karaoke accompaniment data 1 and the vocal data 1 to obtain mixed data 1, and plays the mixed data 1 through the car speakers.

[0232] The karaoke microphone outside the car collects vocal data 2 of user 2 outside the car, and the microphone outside the car sends vocal data 1 to the portable speaker through broadcasting. The portable speaker obtains karaoke accompaniment data 2, mixes the karaoke accompaniment data 2 and the vocal data 2 to obtain mixed data 2, and plays the mixed data 2.

[0233] In this way, people in the car can hear the mixed data 1 played by the car speakers, and people in the car can hear the mixed data 2 played by the portable speakers, thereby realizing independent karaoke inside and outside the car.

[0234] Alternatively, in another embodiment, there are multiple karaoke microphones in the karaoke system; when the karaoke mode of the karaoke system is switched to the separate inside-outside-car karaoke mode, the first karaoke microphone among the multiple karaoke microphones is used to collect first vocal data and directly send the first vocal data to the portable speaker; the portable speaker is also used to obtain first karaoke accompaniment data, mix the first karaoke accompaniment data and the first vocal data to obtain first mixed data, and play the first mixed data; the second karaoke microphone among the multiple karaoke microphones is directly communicated with the in-car speaker; the second karaoke microphone is used to collect second vocal data and directly send the second vocal data to the in-car speaker; the in-car speaker is also used to obtain second karaoke accompaniment data, mix the second karaoke accompaniment data and the second vocal data to obtain second mixed data, and play the second mixed data.
