Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a speaker and an audio playback system. Background Technology

[0002] Currently, after establishing a connection with a media device (such as a television), the speaker can receive audio signals sent by the media device and play them through an amplifier to produce music or other sounds. When the speaker is turned off, the connection with the media device is disconnected, and playback is handled by the media device's built-in speakers. Upon restarting the speaker, it actively re-establishes a connection with the media device and receives audio signals for playback. Because this re-establishment of the communication connection between the speaker and the television results in a certain delay between powering on and starting audio playback, it affects the user experience. Utility Model Content

[0003] The main purpose of this utility model is to provide a speaker that shortens the waiting time for the speaker to play audio signals from media devices after powering on, thereby improving the user experience.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0021] Currently, when the speaker is turned off, the TV can detect the speaker's shutdown based on the communication connection between the two devices, and the TV will play sound through its built-in speakers. When the speaker is turned on, it will actively re-establish the eARC (Enhanced Audio Return Channel) connection with the TV and will play audio again through the speaker. However, re-establishing the eARC connection takes time; tests show that it takes about 6-8 seconds. Therefore, it takes 6-8 seconds for the speaker to play sound after being turned on, which significantly impacts the user experience.

[0022] Based on this, the present invention provides a speaker. In the first embodiment of the present invention, please refer to... Figure 1 The speaker 10 may include:

[0023] Communication module 11 is connected to processing chip 12 and media device 20 respectively, and is used to receive audio signals sent by media device and transmit them to processing chip 12;

[0024] The processing chip 12 is connected to the communication module 11 and the power amplifier module 13 respectively. It is used to transmit the received audio signal to the power amplifier module 13 and to control the communication module 11 to maintain the communication connection with the media device 20 when the speaker 10 is in the off state.

[0025] The power amplifier module 13 is connected to the processing chip 12 and is used to receive and play audio signals.

[0026] It should be noted that the speaker 10 can be a soundbar or other type of speaker, capable of establishing a wired communication connection with the media device 20 to receive and play audio signals from the media device 20. The communication module 11 can be a repeater, capable of establishing a corresponding communication channel with the media device 20 to transmit audio signals.

[0027] In this embodiment of the invention, the processing chip 12 is the core control unit of the speaker, and its functions include processing the received audio signal and transmitting the processed audio signal to the connected power amplifier module for audio playback. The power amplifier module 13 can be a loudspeaker, mainly used to play the audio signal transmitted by the processing chip 12.

[0028] The processing chip 12 can continue operating even when the speaker is powered off. It controls the internal components of the speaker to enter sleep mode and maintains the connection between the communication module 11 and the media device 20. Thus, when the speaker is powered on again, there is no need to re-establish the communication connection with the media device, saving waiting time. This allows the speaker to quickly receive the audio signal transmitted from the media device and output sound immediately after powering on, based on the maintained communication connection, thus improving the user experience.

[0029] It should be noted that, in this embodiment of the invention, the speaker enters sleep mode after being turned off; although it is powered off, it is still powered on. If the speaker has lost power after being turned off, it is necessary to re-establish the communication connection with the media device.

[0030] In one feasible embodiment, such as Figure 1 As shown, one end of the communication module 11 is wired to the processing chip 12, and the other end is wired to the media device 20. The communication module 11 is used to establish a communication connection with the media device 20 after the speaker 10 is powered on.

[0031] Specifically, the communication module 11 is controlled by the processing chip 12 and can actively establish a communication connection with the media device 20 after the speaker 10 is powered on, so as to receive the audio signals transmitted by the media device 20.

[0032] For example, the speaker 10 and the media device 20 can be connected via eARC, and the physical devices can be connected via an HDMI (High Definition Multimedia Interface) cable.

[0033] In one feasible embodiment, the processing chip is an HDMI chip, for example, a SPA300 / MTK chip, and the power amplifier module can be an AMP (Amplifier), such as... Figure 2 As shown, one end of the HDMI chip (main IC, IC refers to Integrated Circuit Chip) is wired to the communication module (Repeater), and the other end is wired to the power amplifier module. The processing chip is also used to decode the received audio signal and transmit it to the power amplifier module for the power amplifier module to play the audio signal.

[0034] Furthermore, the HDMI chip is also used to control the speaker to enter sleep mode after the speaker is turned off, and to keep the HDMI chip and communication module running to ensure that the connection with the media device is not lost, reducing the waiting time after the user turns on the speaker.

[0035] In one feasible embodiment, the HDMI chip is also used to perform heartbeat detection after establishing an HDMI eARC connection between the communication module and the media device, and to control the power amplifier module to play audio signals when the speaker is not powered on for the first time and the heartbeat detection is normal.

[0036] This can be understood as follows: to ensure uninterrupted communication between the speaker's communication module and the media device, the HDMI chip uses a heartbeat detection method to monitor the communication connection status between the two. Thus, if the speaker is not powered on for the first time (meaning a communication connection was established with the media device before powering on), and the heartbeat detection is normal, it indicates that the communication connection remains uninterrupted. The HDMI chip can then directly transmit the received audio signal to the amplifier module for audio playback.

[0037] For example, when the media device is a TV, a feasible speaker (such as a soundbar) communicates with the TV as follows: Figure 2 As shown, the TV 20 and the communication module 11 (Repeater) in the speaker 10 can be connected via eARC / ARC to achieve CEC (Consumer Electronics Control). The Repeater transmits audio data to the processing chip 12 (SPA300 / MTK), specifically via IIS (Inter-IC Sound, a digital audio transmission standard) data or SPDIF (Sony / Philips Digital Interface, an interface standard for transmitting high-quality digital audio). Furthermore, the Repeater and processing chip 12 are connected via the IIC (Inter-Integrated Circuit) bus, and the SPA300 / MTK chip and amplifier module 13 (AMP) can also be connected via the IIC bus. The SPA300 / MTK chip sends the decoded IIS data (i.e., audio data) to the AMP for playback.

[0038] For example, in conjunction with the technical solutions disclosed in the foregoing embodiments, a feasible speaker control process is as follows: Figure 3As shown, firstly, after the speaker (such as a soundbar) is powered on, it is checked whether it is the first power-on. If it is the first power-on, the built-in HDMI chip is in the power-on working state, the 5V is turned off, the HDMI hatpling is pulled low, and then after a delay of 700ms, the 5V is turned on, the HDMI hatpling is pulled high, and the soundbar initiates an ERC connection to the TV through the ERC_send_comma soundbar. It checks whether the ERC heartbeat monitoring is successful after 120ms. If the ERC is successfully connected and the bitrate information is monitored, the IIS is opened after the bitrate stabilizes. After the HDMI chip receives the IIS data, the speaker starts playing the audio signal. If it is not the first power-on, it directly checks whether the ERC heartbeat monitoring is successful after 120ms. If the ERC is successfully connected and the bitrate information is monitored, the IIS is opened after the bitrate stabilizes. After the HDMI chip receives the IIS data, the speaker starts playing the audio signal.

[0039] Based on the first embodiment described above, a second embodiment of the present invention is proposed. In the second embodiment, reference is made to... Figure 4 An audio playback system comprising the speaker in the first embodiment described above is disclosed. The audio playback system includes a speaker 10 and a media device 20 communicatively connected to the speaker.

[0040] Furthermore, such as Figure 5 As shown, the media device 20 can be a television (TV), and the communication connection between the television and the speaker is an HDMI Earc connection. The television (TV) is used to transmit audio signals to the speaker when the speaker is turned on, so that the audio signals can be played through the speaker. When the speaker is turned off, the television (TV) plays audio signals through its built-in speaker.

[0041] In another feasible embodiment, such as Figure 4 As shown, the audio playback system also includes an audio signal source device 30, which is connected to the television 20 for communication. The audio signal source device 30 is used to transmit audio signals to the television 20.

[0042] In this context, an audio signal source device can be understood as a device used to provide audio signals; it is the source of audio signal transmission, such as... Figure 5 As shown, the audio signal source device can be a DVD (Digital Video Disc) player or a BDP player. For example, the audio signal from a BDP (Blu-ray Disc Player) can be transmitted to the TV via an HDMI cable between the DCD and the TV, and then the TV transmits it to the soundbar for playback.

[0043] Naturally, since the audio playback system of this embodiment includes all the technical solutions of all embodiments of the speaker in the first embodiment, the audio playback system can also achieve technical effects such as shortening the waiting time for the speaker to play audio signals from the media device after powering on and improving the user experience.

[0044] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
