[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0042] The following description, with reference to the accompanying drawings, outlines an audio playback method, apparatus, electronic device, and storage medium for a car seat according to embodiments of this application. Addressing the problem mentioned in the background art that vehicles cannot meet users' personalized and privacy-conscious audio playback needs, this application provides an audio playback method for a car seat. In this method, by detecting whether the vehicle receives an audio playback command from the car seat, and upon receiving the command, the pressure of the user's head on the headrest is obtained. When the pressure is within a first pressure range, a bone conduction speaker is controlled to play audio based on the audio playback command; when the pressure is within a second pressure range, both the bone conduction speaker and a directional speaker are controlled to play audio based on the command; and when the pressure is within a third pressure range, the directional speaker is controlled to play audio based on the command. This solves the problem that vehicles cannot meet users' personalized and privacy-conscious audio playback needs. This application arranges bone conduction speakers and directional speakers on the seat, and by coordinating the operation and switching of the bone conduction speakers and directional speakers, the personalized and privacy-conscious audio playback needs of the user are met.

[0043] Before introducing the audio playback method of the car seat in the embodiments of this application, let's first introduce the car seat proposed in the embodiments of this application.

[0044] The car seat includes a seat body consisting of a headrest, a backrest, and a seat cushion. The headrest, backrest, and seat cushion are equipped with at least one pair of bone conduction speakers 1, and the headrest is also equipped with at least one pair of directional speakers 2.

[0045] like Figure 1 As shown, Figure 1 The speaker layout for the car seat includes a pair of bone conduction speakers in the headrest, backrest, and seat cushion, as well as a pair of directional speakers in the headrest.

[0046] Among them, 1. The car seat body of this application embodiment: consists of a headrest, a backrest and a seat cushion, providing basic support functions.

[0047] 2. Bone conduction loudspeakers include bone conduction vibration transducer assemblies: These are located on the front of the seat where they can contact the user's head, and are used to convert between audio electrical signals and vibration signals. These transducers convert the input audio electrical signals into vibration signals, which are transmitted to the inner ear through the human skull.

[0048] 3. Directional speakers: Installed in specific positions on the seat to play high-quality sound. The bone conduction speakers can be adjusted to suit different auditory needs, such as navigation prompts or entertainment music.

[0049] 4. Adapter: Used to connect the bone conduction transducer assembly and the directional speakers, ensuring effective communication and coordinated operation between them. Headrest Structure: At least one pair of bone conduction components and at least one pair of directional speakers are spaced apart on the headrest body. The pair of bone conduction components are connected by a vibration belt, and the pair of directional speakers are also fixed to the headrest body by corresponding connectors.

[0050] 5. Capacitive sensor measurement technology: detects the force of the bone conduction speaker on the user's head.

[0051] It should be noted that the car seat in this embodiment also includes an audio control component: including a pressure sensor and a control unit. When the user's pressure on the headrest is insufficient to trigger the headrest bone conduction speaker, the directional speaker is activated to work in conjunction with the backrest and seat cushion speakers to produce sound. The bone conduction speaker in this embodiment adopts a ring-shaped distribution of ventilation slots, which effectively suppresses sound leakage and prevents the bone conduction speaker's energy from leaking into the air and causing sound leakage problems. The bone conduction speaker in this embodiment also improves the sound quality of the bone conduction speaker through specific design, especially the sound quality in the mid-low frequency range, and increases wearing comfort. By optimizing the design of the vibration unit, it has a better frequency response curve.

[0052] Specifically, Figure 2 This is a schematic flowchart illustrating an audio playback method for a car seat provided in an embodiment of this application.

[0053] like Figure 2 As shown, the audio playback method for this car seat includes the following steps:

[0054] In step S101, it is detected whether the vehicle has received an audio playback command from the car seat.

[0055] Specifically, when a user needs the car seat to play audio, an audio playback command can be sent. In actual execution, this application embodiment can integrate a sending module into the car seat. When the user issues an audio playback command through the control interface on the seat, the module can send the command to the vehicle's information system and configure a receiving module in the vehicle's information system to listen for and receive the audio playback command from the car seat.

[0056] In step S102, upon receiving an audio playback command, the pressure of the user's head on the headrest is obtained.

[0057] It is understood that bone conduction speakers require contact between the user and the seat to play audio, and the optimal experience is achieved through contact between the skull and the speaker. This embodiment of the application can acquire the pressure of the user's head against the headrest to activate or deactivate the bone conduction speakers, or to allocate between bone conduction speakers and directional speakers, based on this pressure. In actual implementation, pressure sensors are installed inside the headrest to detect changes in pressure on the headrest.

[0058] Optionally, in some embodiments, upon receiving an audio playback instruction, the method further includes: acquiring the user's audio playback parameters; determining a first volume of the bone conduction speaker and a second volume of the directional speaker based on the audio playback parameters; and controlling the bone conduction speaker to play audio at the first volume and controlling the directional speaker to play audio at the second volume.

[0059] It is understood that the embodiments of this application achieve audio playback through bone conduction speakers and / or directional speakers. Users can set audio playback parameters in a personalized way, for example, bone conduction volume ratio of 50% and directional speaker volume ratio of 50%, so as to meet personalized audio playback needs through split-screen bone conduction speakers and directional speakers.

[0060] In addition, audio playback parameters assign audio targets to bone conduction speakers and directional speakers. For example, bone conduction speakers are used to play music for users, while directional speakers are used to play audio prompts such as phone calls and navigation.

[0061] Optionally, in some embodiments, after obtaining the pressure of the driver's head against the headrest, the method includes: determining whether the pressure is lower than a first pressure threshold; if the pressure is lower than the first pressure threshold, generating an abnormality reminder instruction and issuing an abnormality reminder according to the abnormality reminder instruction.

[0062] The first pressure threshold can be preset by the user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations; no specific limitation is made here.

[0063] It is understandable that bone conduction speakers require the user to contact the seat to play audio, and the optimal position for the experience is when the skull contacts the bone conduction speaker. When the user issues an audio playback command for the car seat, if the pressure between the user's skull and the headrest is insufficient, the experience is poor. This application embodiment can issue a reminder to prompt the user to adjust their sitting posture.

[0064] In practice, reminders can be provided in the following ways: 1. Visual reminders: An indicator light on the dashboard flashes or displays a message prompting the driver to approach the headrest. 2. Auditory reminders: The in-vehicle speakers play a reminder tone or voice prompt. 3. Tactile feedback: The driver is alerted by seat vibration or slight headrest vibration.

[0065] In step S103, when the pressure is in the first pressure range, the bone conduction speaker is controlled to play audio based on the audio playback command; when the pressure is in the second pressure range, the bone conduction speaker and the directional speaker are controlled to play audio based on the audio playback command; and when the pressure is in the third pressure range, the directional speaker is controlled to play audio based on the audio playback command.

[0066] Bone conduction speakers transmit sound directly through the skull, rather than through the air. They convert sound signals into vibrations, which are transmitted through the bones to the inner ear and then perceived by the auditory nerve. Directional speakers, on the other hand, transmit sound through the air and can play according to the user's auditory preferences and seating position to provide the best listening experience.

[0067] It should be noted that the minimum value of the first pressure range is greater than or equal to the maximum value of the second pressure range, and the minimum value of the second pressure range is greater than or equal to the maximum value of the third pressure range.

[0068] When the pressure is in the third pressure range, the user's skull has very little contact with the headrest, which can result in almost no audio being heard. In this embodiment, the directional speaker can be controlled to play audio based on the audio playback command. In the actual execution process, the system will determine that the driver's head position is not suitable for using bone conduction headphones, and the system will automatically switch to a regular speaker.

[0069] When the pressure is in the first pressure range, it is most suitable to play audio through a bone conduction speaker based on audio playback commands.

[0070] like Figure 3 As shown, Figure 3 There are two states for the headrest speaker to operate. When the driver applies enough pressure to the headrest to support the bone conduction headphones, the bone conduction headphones operate independently in the headrest. When the pressure is insufficient, the ordinary speakers with lower power are turned on to help the user obtain a clear listening experience.

[0071] Furthermore, in some embodiments, when the pressure is in the second pressure range, controlling the bone conduction speaker and the directional speaker to play audio based on an audio playback command includes determining a third volume of the bone conduction speaker and a fourth volume of the directional speaker based on the pressure, and controlling the bone conduction speaker to play audio at the third volume and controlling the directional speaker to play audio at the fourth volume.

[0072] When the pressure is in the second pressure range, the user's skull is in greater contact with the headrest, which may result in a lower audio volume. In this case, the audio can be played by both bone conduction speakers and directional speakers. The volume ratio of the bone conduction speakers and directional speakers can be determined according to the pressure. For example, the greater the pressure, the louder the bone conduction speakers and the quieter the directional speakers.

[0073] In summary, the seat audio system combining bone conduction and directional speakers in this application, through optimized design and technological innovation, solves the sound leakage problem existing in traditional audio systems, providing users with a more comfortable and private listening environment.

[0074] According to the audio playback method for car seats proposed in this application, the method detects whether the vehicle receives an audio playback command from the car seat. When an audio playback command is received, the pressure of the user's head on the headrest is obtained. When the pressure is in a first pressure range, the bone conduction speaker is controlled to play audio based on the audio playback command. When the pressure is in a second pressure range, both the bone conduction speaker and the directional speaker are controlled to play audio based on the audio playback command. When the pressure is in a third pressure range, the directional speaker is controlled to play audio based on the audio playback command. This solves the problem that vehicles cannot meet the user's personalized and private audio playback needs. This application arranges bone conduction speakers and directional speakers on the seat, and by coordinating the operation and switching of the bone conduction speakers and directional speakers, the user's personalized and private audio playback needs are met.

[0075] Next, with reference to the accompanying drawings, an audio playback device for a car seat according to an embodiment of this application is described.

[0076] Figure 4 This is a block diagram of an audio playback device for a car seat according to an embodiment of this application.

[0077] A car seat comprises a seat body consisting of a headrest, a backrest, and a seat cushion. The headrest, backrest, and seat cushion each have at least one pair of bone conduction speakers, and the headrest also has at least one pair of directional speakers, such as... Figure 4 As shown, the audio playback device 10 of the car seat includes: a detection module 100, an acquisition module 200, and an audio playback module 300.

[0078] The detection module 100 is used to detect whether the vehicle has received an audio playback command from the car seat.

[0079] The acquisition module 200 is used to acquire the pressure of the user's head on the headrest when an audio playback command is received.

[0080] The audio playback module 300 is used to control the bone conduction speaker to play audio based on the audio playback command when the pressure is in the first pressure range, to control the bone conduction speaker and the directional speaker to play audio based on the audio playback command when the pressure is in the second pressure range, and to control the directional speaker to play audio based on the audio playback command when the pressure is in the third pressure range.

[0081] Optionally, in some embodiments, the minimum value of the first pressure range is greater than or equal to the maximum value of the second pressure range, and the minimum value of the second pressure range is greater than or equal to the maximum value of the third pressure range.

[0082] Optionally, in some embodiments, when an audio playback instruction is received, the acquisition module 100 further includes an acquisition unit and a first audio playback unit.

[0083] The acquisition unit is used to acquire the user's audio playback parameters.

[0085] Optionally, in some embodiments, after obtaining the pressure of the driver's head against the headrest, the acquisition module 100 includes a judgment unit and a reminder unit.

[0086] The judgment unit is used to determine whether the pressure is lower than the first pressure threshold.

[0087] The reminder unit is used to generate an abnormality reminder command when the pressure is lower than a first pressure threshold, and to provide an abnormality reminder according to the abnormality reminder command.

[0088] Optionally, in some embodiments, when the pressure is in the second pressure range, the bone conduction speaker and the directional speaker are controlled to play audio based on an audio playback command. The audio playback module 300 includes a second audio playback unit.

[0089] The second audio playback unit is used to determine the third volume of the bone conduction speaker and the fourth volume of the directional speaker based on pressure, and to control the bone conduction speaker to play audio at the third volume and control the directional speaker to play audio at the fourth volume.
