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

[0042] The following describes the audio playback method, device, electronic device and storage medium of the car seat of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the vehicle mentioned in the above background technology cannot meet the personalized and private audio playback needs of users, the present application provides an audio playback method for a car seat, in which the pressure of the user's head on the headrest is obtained by detecting whether the vehicle receives the audio playback instruction of the car seat when the audio playback instruction is received; when the pressure is in the first pressure interval, the bone conduction speaker is controlled to play the audio based on the audio playback instruction; when the pressure is in the second pressure interval, the bone conduction speaker and the directional speaker are controlled to play the audio based on the audio playback instruction; when the pressure is in the third pressure interval, the directional speaker is controlled to play the audio based on the audio playback instruction. Thus, the problem that the vehicle cannot meet the personalized and private audio playback needs of users is solved. The present application arranges bone conduction speakers and directional speakers on the seat, and meets the personalized and private audio playback needs of users by coordinating the operation and switching of the bone conduction speakers and the directional speakers.

[0043] Before introducing the audio playback method of the car seat according to the embodiment of the present application, the car seat proposed in the embodiment of the present application is first introduced.

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

[0045] like Figure 1 As shown, Figure 1 The speaker layout on the car seat is that the headrest, backrest and seat cushion are each equipped with a pair of bone conduction speakers, and there is also a pair of directional speakers in the headrest.

[0046] Among them, 1. The car seat body of the embodiment of the present application: consists of a pillow, a backrest and a cushion, providing basic supporting functions.

[0047] 2. The bone conduction speaker includes a bone conduction vibration transducer group: it is set on the front of the seat where it can contact the user's head, and is used to convert audio electrical signals into vibration signals. These transducers convert the input audio electrical signals into vibration signals and transmit them to the inner ear through the human skull.

[0048] 3. Directional speakers: Installed in a specific position of the seat, used to play high-quality sound, used to move away from the driver's head. Bone conduction speakers can be adjusted for different auditory needs, such as navigation prompts or entertainment music.

[0049] 4. Adapter: used to connect the bone conduction vibration transducer group and the directional speaker to ensure effective communication and collaborative work between the two. Headrest structure: at least one pair of bone conduction components and at least one pair of directional speakers are arranged 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 through corresponding connectors.

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

[0051] It should be noted that the car seat in the embodiment of the present application also includes an audio control component: including a pressure sensor and a control unit. When the user's pressure on the headrest is not enough to trigger the headrest bone conduction speaker, the directional speaker is started to work together with the backrest and seat cushion speakers to produce sound; the bone conduction speaker in the embodiment of the present application adopts a ring-shaped ventilation groove design to effectively suppress sound leakage and avoid the sound leakage problem caused by the energy of the bone conduction speaker leaking into the air; the bone conduction speaker in the embodiment of the present application also improves the sound quality of the bone conduction speaker through specific design, especially the sound quality in the mid- and low-frequency bands, and increases wearing comfort, and optimizes the design of the vibration unit to give it a better frequency response curve.

[0052] Specifically, Figure 2 A schematic flow chart of an audio playback method for a car seat provided in an embodiment of the present application.

[0053] like Figure 2 As shown, the audio playing method of the car seat comprises the following steps:

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

[0055] Specifically, when the user needs the car seat to play audio, an audio playback instruction can be sent. In the actual implementation process, the embodiment of the present application can integrate a sending module in the car seat. When the user issues an audio playback instruction through the control interface on the seat, the module can send the instruction to the vehicle's information system and configure a receiving module in the vehicle's information system to monitor and receive audio playback instructions from the car seat.

[0056] In step S102, when an audio play instruction is received, the pressure of the user's head on the headrest is obtained.

[0057] It is understandable that the bone conduction speaker needs to be in contact with the seat by the user to achieve audio playback, and the best experience is when the skull contacts the bone conduction speaker. The embodiment of the present application can obtain the pressure of the user's head on the headrest to turn on or off the bone conduction speaker according to the pressure, or allocate the bone conduction speaker and the directional speaker. In the actual implementation process, pressure sensors are installed inside the seat headrest, and these sensors can detect the pressure changes on the headrest.

[0058] Optionally, in some embodiments, when an audio playback instruction is received, it also includes: obtaining the user's audio playback parameters; determining a first volume of the bone conduction speaker and a second volume of the directional speaker according to 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 can be understood that the embodiments of the present application implement audio playback through bone conduction speakers and / or directional speakers, and users can personalize the audio playback parameters, for example, the bone conduction volume accounts for 50% and the directional speaker accounts for 50%, so as to meet personalized audio playback needs through split-screen bone conduction speakers and directional speakers.

[0060] In addition, the audio playback parameters allocate the audio targets of the bone conduction speaker and the directional speaker. For example, the bone conduction speaker is used to play music, and the directional speaker is used to play prompt audio such as phone calls and navigation.

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

[0062] The first pressure threshold may be preset by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, which is not specifically limited here.

[0063] It is understandable that the bone conduction speaker requires the user to be in contact with the seat to achieve audio playback, and the best experience is when the skull is in contact with the bone conduction speaker. After 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. The embodiment of the present application can issue a reminder to remind the user to adjust his or her sitting posture.

[0064] In actual implementation, reminders can be given in the following ways: 1. Visual reminder: The indicator light on the dashboard flashes or a message is displayed to remind the driver to move closer to the headrest. 2. Auditory reminder: The car's speakers play a reminder tone or voice prompt. 3. Haptic feedback: The seat vibrates or the headrest vibrates slightly to remind the driver.

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

[0066] Among them, bone conduction speakers transmit sound directly through the skull instead of through the air. It converts sound signals into vibration signals, which are transmitted to the inner ear through human bones and then perceived by the auditory nerve; directional speakers transmit sound through the air. Directional speakers can play according to the user's hearing preferences and seat position to provide the best listening experience.

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

[0068] When the pressure is in the third pressure interval, the contact between the user's skull and the headrest is very small, which will result in the audio being almost inaudible. The embodiment of the present application can control the directional speaker to play audio based on the audio playback instruction. In the actual execution process, the system will determine that the driver's head position is not suitable for using bone conduction headphones. At this time, the system will automatically switch to a normal speaker.

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

[0070] like Figure 3 As shown, Figure 3 There are two working states of the speaker in the headrest. When the driver's pressure on the headrest is enough to support the bone conduction headphones to turn on, the bone conduction headphones operate independently in the headrest. If the pressure is insufficient, a lower-power ordinary speaker will be turned on to help users get a clear hearing experience.

[0071] Further, in some embodiments, when the pressure is in the second pressure interval, the bone conduction speaker and the directional speaker are controlled to play audio based on the audio playback instruction, including 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 interval, the user's skull is in closer contact with the headrest, resulting in a smaller audio volume. The audio can be played together through the bone conduction speaker and the directional speaker, wherein the volume ratio of the bone conduction speaker and the directional speaker can be determined according to the pressure. For example, the greater the pressure, the louder the volume of the bone conduction speaker, and the smaller the volume of the directional speaker.

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

[0074] According to the audio playback method for a car seat proposed in the embodiment of the present application, by detecting whether the vehicle has received the audio playback instruction of the car seat, when the audio playback instruction is received, the pressure of the user's head on the headrest is obtained; when the pressure is in the first pressure range, the bone conduction speaker is controlled to play the audio based on the audio playback instruction; when the pressure is in the second pressure range, the bone conduction speaker and the directional speaker are controlled to play the audio based on the audio playback instruction; when the pressure is in the third pressure range, the directional speaker is controlled to play the audio based on the audio playback instruction. Thus, the problem that the vehicle cannot meet the personalized and private audio playback needs of the user is solved. The present application arranges bone conduction speakers and directional speakers on the seat, and meets the personalized and private audio playback needs of the user by coordinating the operation and switching of the bone conduction speakers and the directional speakers.

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

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

[0079] The acquisition module 200 is used to acquire the pressure of the user's head on the headrest when receiving the audio play instruction.

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

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

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

[0086] The judging unit is used to judge whether the pressure is lower than a first pressure threshold.

[0087] The reminder unit is used to generate an abnormal reminder instruction when the pressure is lower than a first pressure threshold, and to make an abnormal reminder according to the abnormal reminder instruction.

[0088] Optionally, in some embodiments, when the pressure is in the second pressure interval, the bone conduction speaker and the directional speaker are controlled to perform audio playback based on the audio playback instruction, and the audio playback module 300 includes a second audio playback unit.

[0089] Among them, 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 control the bone conduction speaker to play audio at the third volume, and control the directional speaker to play audio at the fourth volume.

[0090] It should be noted that the above explanation of the embodiment of the audio playback method for a car seat is also applicable to the audio playback device for a car seat in this embodiment, and will not be repeated here.
