Description

Technical Field

[0001] The present invention relates to the technical field of acoustic equipment, and in particular to a bone conduction sound pad and a bone conduction sound soft package. Background Art

[0002] Currently, soft-pack sound is used so that people can listen to music and voice when attached to the soft-pack object, so as to relieve people's work pressure, meet the needs of most people to listen to soothing music or audiobooks before going to bed, and avoid the pressure and discomfort of the tragus caused by wearing headphones.

[0003] Existing sound-generating soft-package products generally use two methods: built-in speaker and bone conduction. When using built-in speaker, there will be serious sound leakage, which will affect others' rest when playing music; to avoid sound leakage, it is necessary to lower the listening volume, resulting in poor clarity of low-frequency and mid-frequency attenuation and inability to hear clearly; in order to distinguish the speakers, embedded packaging is used, but there are problems such as difficulty in maintenance and cleaning. When using bone conduction technology to generate sound, the internal filler is used as a sound propagation medium. After being compressed, the density of the medium is unevenly distributed, resulting in a change in the speed of sound propagation, causing the direction of sound propagation to be deflected, thereby causing refraction and reflection of sound waves. At the same time, multiple vibrators are placed in the soft package, and the sound waves between the multiple vibrators will produce interference and diffraction in the soft package, resulting in changes in sound intensity and frequency characteristics, resulting in imbalance in the conducted sound quality and volume, and excessive nonlinear distortion.

[0048] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0049] Embodiment 1

[0050] like Figure 4As shown, an embodiment of the present invention provides a bone conduction sound pad, which can be applied to a soft package, and the soft package can be a cushion or a headrest.

[0051] The bone conduction sound pad includes a base pad 1 and a balanced sound-emitting part 2, and the balanced sound-emitting part 2 includes a connection unit 22 and a plurality of bone conduction sound-emitting bodies 21. The connection unit 22 includes one or more first strip structures 221, wherein each first strip structure 221 connects the sound-emitting ends of a plurality of bone conduction sound-emitting bodies 21 to connect the independent sound-emitting ends of a plurality of bone conduction sound-emitting bodies 21 to form a sound-emitting surface. Since the sound-emitting ends of a plurality of bone conduction sound-emitting bodies 21 are connected by the connection unit 22 and then the sound-emitting points of a plurality of bone conduction sound-emitting bodies 21 are connected to form a sound-emitting surface, the sound emitted by the dispersed vibration points is converted into the surface sound of the sound-emitting surface, so that the sound waves output by the sound-emitting points propagate in a straight line along the connection direction of the first strip structure 221 in the connection unit 22, and less refraction and reflection occur, thereby reducing the interference between the sound waves, improving the volume balance, reducing the harmonic distortion, and improving the sound quality.

[0052] The base pad 1 is provided with a storage space to accommodate multiple bone conduction sounding bodies 21, and preferably, one end of the bone conduction sounding body 21 away from the sounding end is placed in the storage space. In some embodiments, the storage space is constructed as multiple storage cavities recessed on the base pad 1, and multiple bone conduction sounding bodies 21 are arranged in a one-to-one correspondence in the multiple storage cavities, and preferably, one end away from the sounding end of the bone conduction sounding body 21 is located in the storage cavity. It can be understood that a person skilled in the art can set a corresponding and adaptive storage space structure according to the shape structure of the connection unit 22 and / or the bone conduction sounding body 21, and the present disclosure does not limit this.

[0053] Among them, in order to reduce the vibration of the end of the bone conduction sound-emitting body 21 away from the sound-emitting end and reduce the sound leakage of the bone conduction sound-emitting body 21 to the mattress, a vibration-damping pad is provided between the bottom end of the bone conduction sound-emitting body and the bottom pad, which can reduce the sound leakage to the bottom pad carrier (such as a mattress, sofa cushion, etc.) by 40%. Preferably, the thickness of the vibration-damping pad is greater than 1 mm, and the Shore hardness of the vibration-damping pad is greater than 40HD.

[0054] Preferably, the base pad 1 is made of rubber. Since the base pad 1 is provided to accommodate a plurality of bone conduction sound-generating bodies 21, the problem of sound leakage caused by the vibration of the bone conduction sound-generating bodies 21 is further reduced.

[0055] In this embodiment, the bone conduction sound-emitting body 21 includes a bone conduction vibrator and a shell, the bone conduction vibrator is arranged in the shell, one end surface of the shell is a sound-emitting end, and the first strip structure 221 is connected to the sound-emitting end of the shell in the bone conduction sound-emitting body 21. It should be noted that the bone conduction sound-emitting body 21 is a prior art and will not be described in detail here. Among them, the connection between the connection unit and the bone conduction sound-emitting body 21 can be achieved in a variety of ways, such as integrated molding, fixed connection or movable connection, as long as the sound waves can be well conducted.

[0056] like Figure 5 and Figure 6 As shown, the connection unit 22 is formed by one or more first strip structures 221 arranged along the first direction. When the connection unit 22 is a first strip structure 221, the first strip structure 221 is connected to the sound-emitting ends of all bone conduction sound-emitting bodies 21 to connect the sound-emitting ends of multiple bone conduction sound-emitting bodies 21 to form a sound-emitting surface, wherein the number of bone conduction sound-emitting bodies 21 connected to the first strip structure 221 is not limited here and is set according to actual conditions.

[0057] like Figure 8 and Fig. 9 As shown, the connecting unit 22 can also be formed by cross-connecting one or more first strip structures 221 arranged along the first direction and one or more first strip structures 221 arranged along the second direction, wherein the first strip structure 221 is connected to the sounding ends of multiple bone conduction sounding bodies 21 to connect the sounding points of multiple bone conduction sounding bodies 21 to form a sounding surface.

[0058] like Figure 7 As shown, the connection unit 22 can also be formed by cross-connecting one or more first strip structures 221 arranged along the first direction and one or more second strip structures 222 arranged along the second direction, wherein the second strip structure 222 is connected to the first strip structure 221 and is not directly connected to the sound-emitting end of the bone conduction sound-emitting body 21. The first strip structure 221 and the second strip structure 222 together form a sound-emitting surface.

[0059] It should be noted that the number of the first strip structures 221 or the second strip structures 222 and the shape formed by the connection of the first strip structures 221 or the second strip structures 222 are designed according to the sound emission area and the shape requirements of the adapted soft package. For example, to adapt to a U-shaped pillow, the above-mentioned shape can present a certain curvature, which is not limited by the present invention.

[0060] In actual application, the balanced sound-emitting part 2 in the bone conduction sound-emitting pad is symmetrical about the Y-axis to avoid the problem of large sound differences between the left and right ears of the human brain when lying on the back.

[0061] The first strip structure 221 can be made of conductive materials such as plastic, wood, and metal, which is not limited in the present invention. Preferably, the Shore hardness of the first strip structure 221 and the second strip structure 222 is greater than 40HD. It should be noted that the materials of the first strip structure 221 and the second strip structure 222 can be the same, and of course different materials can be selected according to actual conditions.

[0062] When the bottom pad 1 needs to be closed, the bone conduction sound pad also includes a top pad 4, which is buckled with the bottom pad 1. In order to make the sound-generating surface better transmit sound waves, the top pad 4 is in contact with the connecting unit 22. Of course, when the bottom pad 1 does not need to be closed, the top pad 4 can be unused.

[0063] like Fig.10 As shown, in order to avoid a large difference in hearing between lying on one's back or leaning against a soft object and lying on one's side or leaning against one's side, the bone conduction sound pad also includes one or two auxiliary sounding parts 3 arranged on the base pad 1. When there is one auxiliary sounding part 3, the auxiliary sounding part 3 is located above or below the balanced sounding part 2 in the Y-axis direction. When there are two or more auxiliary sounding parts 3, the auxiliary sounding parts 3 are respectively located above and below the balanced sounding part 2 in the Y-axis direction. Preferably, when there are two or more auxiliary sounding parts 3, the auxiliary sounding parts 3 are evenly distributed above and below the balanced sounding part 2 in the Y-axis direction.

[0064] The auxiliary sound-emitting part 3 includes at least one auxiliary sound-emitting body 31, and the volume output by the auxiliary sound-emitting body 31 is greater than the volume output by the bone conduction sound-emitting body 21. The specific form of the auxiliary sound-emitting part 3 is designed according to the sound-emitting area requirement. Fig.12 and Fig.13 As shown, the structure of the auxiliary sounding body 31 in the auxiliary sounding part 3 can adopt the structure of the prior art, that is, a plurality of independently arranged bone conduction sounding bodies. Fig.11 As shown, the auxiliary sound-emitting part 3 can of course be preferably the structural form of the balanced sound-emitting part 2 in the present invention, that is, the auxiliary sound-emitting part 3 also includes an auxiliary connecting unit 32, and the structure of the auxiliary connecting unit 32 is the same as that of the connecting unit 22 and will not be repeated here.

[0065] Among them, the auxiliary sounding body 31 in the auxiliary sounding part 3 distributed above and / or below the Y-axis direction of the balanced sounding part 2 has a larger audio signal input amplitude than the bone conduction sounding body 21 in the balanced sounding part 2, and the positive range is 1 to 30 dBV. Within this input amplitude range, the parameters can be adjusted according to the area, thickness, and density of the soft package to adapt to use. When lying on your back or leaning forward, the volume of the auxiliary sounding body 31 in the auxiliary sounding part 3 distributed above and / or below the Y-axis direction of the balanced sounding part 2 is high, which can be conducted through the air, making up for the problem of small sound picked up in the protuberance area of ​​the brain during bone conduction. When lying on your side or leaning on your side, the tragus falls on the balanced sounding part 2, and the ear close to the side of the sounding facial bone in the balanced sounding part 2 can also block the air conduction sound of the auxiliary sounding body 31 in the auxiliary sounding part 3. The sound picked up by the tragus mainly comes from the balanced sounding part 2, thereby avoiding the problem of large volume difference between lying on your back (leaning forward) and lying on your side (leaning on your side).

[0066] like Figure 4As shown, the bone conduction sound pad also includes a control unit 6, which is used to control the operation or non-operation of multiple bone conduction sounding bodies 21 and auxiliary sounding bodies 31. In order to effectively reduce power consumption and further avoid sound leakage, the bone conduction sound pad also includes multiple pressure sensors 7 located on the base pad 1, and the multiple pressure sensors 7 are distributed in the human brain landing area on the bone conduction sound pad. When the pressure value collected by any pressure sensor 7 is greater than the preset value, the control unit 6 controls the bone conduction sounding body 21 in the balanced sounding part 2 and the auxiliary sounding body 31 in the auxiliary sounding part 3 at the position corresponding to the pressure sensor 7 to work, and the remaining bone conduction sounding bodies 21 and auxiliary sounding bodies 31 do not work. Among them, the bone conduction sounding body 21 and auxiliary sounding body 31 at the position corresponding to the pressure sensor 7 are the bone conduction sounding bodies 21 and auxiliary sounding bodies 31 within the specified range of the pressure sensor 7. That is, the bone conduction sound emitting body 21 in the balanced sound emitting part 2 and the auxiliary sound emitting body 31 in the auxiliary sound emitting part 3 work within the specified range, and the bone conduction sound emitting body 21 in the balanced sound emitting part 2 and the auxiliary sound emitting body 31 in the auxiliary sound emitting part 3 do not work in other areas, thereby further solving the problem of large sound differences between the left and right ears when the human brain pillow is placed on different positions of the soft package, and effectively reducing power consumption and improving sound leakage. Among them, the specified range is the range where the human brain actually lands and the distance range within 3-5cm of the actual landing point of the human brain along the X-axis and Y-axis.

[0067] Among them, the control unit 6 includes a main shell, a PCB board arranged inside the main shell, and multiple buttons, a charging port and signal lines arranged outside the main shell. The signal line is connected to the connecting line unit 8, and the control unit 6 is powered by an external DC power supply connected to the charging port.

[0068] Of course, the control unit 6 is provided with a voice and music mode switch to avoid the degradation of sound quality caused by the difference in sonic characteristics of the voice and music in the soft package body 5 .

[0069] The control circuit of the control unit 6 automatically stops the input signals of the bone conduction sounding body 21 in the balanced sounding part 2 and the auxiliary sounding body 31 in the auxiliary sounding part 3 after the call is answered, and the audio output is switched to the communication device. After the call is over, the bone conduction sounding body 21 in the balanced sounding part 2 and the auxiliary sounding body 31 in the auxiliary sounding part 3 are resumed. Among them, the outlet mode of the bone conduction sound pad is in the middle of the bottom pad 1, which effectively adapts to the left and right hand usage habits of people when resting.

[0070] Embodiment 2

[0071] like Figure 1-3 As shown, this embodiment provides a bone conduction sound-generating soft package, including a soft package body 5 and the bone conduction sound-generating pad in Embodiment 1. The soft package body 5 can be a pillow or a headrest.

[0072] The bone conduction sound pad is placed inside or at the bottom of the outside of the soft bag body 5 to support the soft bag body 5 under pressure. Figure 1 As shown, the bone conduction sound pad is independently placed on the outer bottom of the soft bag body 5, and can also be quickly fixed with the soft bag cover 9 of the soft bag body 5 by snapping or other methods, or as shown in FIG. Figure 2 As shown, the bone conduction sound pad can also be installed in the soft package body 5, or as shown in Figure 3 As shown, the bone conduction sound pad is installed between the soft packaging body 5 and the soft packaging sleeve 9.

[0073] like Fig.11 As shown, the soft package body 5 is divided into an A region 51, a B region 52 and a C region 53 arranged in sequence along the Y-axis direction according to the tragus landing point when a person lies on his side or leans on the soft package body 5. The Y-axis length of the B region 52 is centered on the horizontal line where the tragus landing point is located. The balanced sound-emitting part 2 is located in the B region 52, and the auxiliary sound-emitting part 3 is located in the A region 51 and / or the C region 53. Among them, the B region 52 is the tragus landing point area. Preferably, the Y-axis length range of the B region 52 is about 10 cm above and below the horizontal center line of the tragus, and the X-axis length range is the length of the entire soft package body 5.

[0074] like Fig.12 As shown, the soft package body 5 also includes a D area 54, which is the pressure position range of the human brain. The pressure sensor 7 is located in the D area 54. Preferably, the Y-axis length range of the D area 54 is about 20 cm above and below the horizontal center line of the tragus, and the X-axis length range is the length of the entire soft package body 5. Fig.13 As shown, the soft package body 5 also includes an E area 55, which is the range of the actual landing point of the human brain and the distance range within 3-5 cm along the X-axis and the Y-axis from the actual landing point of the human brain.

[0075] The sound pad is placed inside or outside the bottom of the soft bag body 5. The bone conduction sound pad has a certain hardness and can play a certain supporting role for the compressed soft bag body 5. When it is placed inside or outside the bottom of the soft bag body 5, it can support the soft bag body 5 to reduce the deformation of the soft bag body 5 when it is compressed, and reduce the deformation of the filling material inside the soft bag body 5 after the force is applied to the soft bag body 5, further improving the sound quality. At the same time, since the amplitude and phase of the input sound source of the bone conduction sound body 21 of the balanced sound-generating part 2 in the bone conduction sound pad are the same, multiple bone conduction sound bodies 21 are connected to the connection unit 22 with uniform density, realizing the superposition and enhancement effect of sound waves, and avoiding the refraction of sound waves in the deformed soft bag body 5.
