Description

Bone conduction sound emitting pad and bone conduction sound emitting soft pack TECHNICAL FIELD

[0001] The present application relates to the technical field of acoustic devices, in particular to a bone conduction sound emitting pad and a bone conduction sound emitting soft pack. BACKGROUND

[0002] Currently, soft pack sound emission is used so that people can listen to music and voice when attaching the soft pack, thereby relieving the work pressure of people and meeting the needs of most people to listen to soothing music or audio books before sleeping, and avoiding the eardrum compression and discomfort caused by wearing earphones.

[0003] The existing sound emitting soft pack products generally use built-in loudspeaker and bone conduction. When the built-in loudspeaker is used, there is a serious sound leakage, which affects the rest of others when playing music. In order to avoid sound leakage, the listening volume needs to be reduced, which causes poor clarity of low frequency and medium frequency attenuation. In order to distinguish the sound box, the package is embedded, but there are problems such as difficult maintenance and cleaning. When the bone conduction technology soft pack sound emission is used, the internal filler serves as a sound propagation medium, and the density of the medium is unevenly distributed after being compressed, which changes the speed of sound propagation, causes the direction of sound propagation to be deflected, and thus causes refraction and reflection of sound waves. At the same time, multiple vibrators are placed in the soft pack, and the sound waves between the multiple vibrators will produce interference and diffraction phenomena in the soft pack, which causes changes in sound intensity and frequency characteristics, resulting in unbalanced and excessively large nonlinear distortion of the sound quality and volume.

DETAILED DESCRIPTION

[0039] In order to better explain the present application, so as to be understood, the present application is described in detail below by specific embodiments, combined with the drawings.

[0040] Embodiment one

[0041] As shown in Figure 4, the bone conduction sound emitting pad provided by the embodiment of the present application can be applied in a soft pack, which can be a cushion or a headrest.

[0042] The bone conduction sound emitting pad comprises a bottom pad 1 and a balanced sound emitting part 2, and the balanced sound emitting part 2 comprises a connecting unit 22 and a plurality of bone conduction sound emitting bodies 21. The connecting unit 22 comprises one or more first strip structures 221, wherein each first strip structure 221 connects the sound emitting ends of the plurality of bone conduction sound emitting bodies 21 to connect the sound emitting ends of the plurality of bone conduction sound emitting bodies 21 to form a sound emitting surface. Since the sound emitting ends of the plurality of bone conduction sound emitting bodies 21 are connected by the connecting unit 22, the sound emitting points of the plurality of bone conduction sound emitting bodies 21 are connected to form a sound emitting surface, so that the dispersed vibration points are converted into surface sound emission of the sound emitting surface, the sound waves output by the sound emitting points are linearly propagated along the connection direction of the first strip structure 221 in the connecting unit 22, the refraction and reflection phenomena are less likely to occur, the interference between the sound waves is reduced, the sound volume balance is improved, the harmonic distortion is reduced, and the sound quality is improved.

[0043] The bottom pad 1 is provided with a containing space to accommodate a plurality of bone conduction sound bodies 21, and preferably the end of the bone conduction sound body 21 away from the sound emitting end is placed in the containing space. In some embodiments, the containing space is configured as a plurality of containing cavities recessed on the bottom pad 1, and the plurality of bone conduction sound bodies 21 are arranged one by one in the plurality of containing cavities, and preferably the end of the bone conduction sound body 21 away from the sound emitting end is located in the containing cavity. It can be understood that those skilled in the art can set a corresponding adaptive containing space structure according to the shape and structure of the connecting unit 22 and / or the bone conduction sound body 21, and the present disclosure does not limit this.

[0044] In order to reduce the vibration of the end of the bone conduction sound body 21 away from the sound emitting end and reduce the leakage of the bone conduction sound body 21 to the mattress, a damping pad is provided between the bottom end of the bone conduction sound body and the bottom pad to reduce the leakage of sound to the bottom pad bearing (such as mattress, sofa pad, etc.). The thickness of the damping pad is greater than 1mm, and the Shore hardness of the damping pad is greater than 40HD.

[0045] Preferably, the material of the bottom pad 1 is rubber. Due to the bottom pad 1 containing a plurality of bone conduction sound bodies 21, the problem of sound leakage caused by the vibration of the bone conduction sound body 21 is further reduced.

[0046] In the present embodiment, the bone conduction sound 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 with the sound emitting end of the shell in the bone conduction sound body 21. It should be noted that the bone conduction sound body 21 is a prior art and will not be described here. The connection between the connecting unit and the bone conduction sound body 21 can be achieved in various ways, such as one-piece molding, fixed connection or movable connection, as long as it can well conduct sound waves.

[0047] As shown in FIGS. 5 and 6, the connecting unit 22 is formed by one or more first strip structures 221 arranged along the first direction. When the connecting unit 22 is a first strip structure 221, the first strip structure 221 is connected with the sound emitting ends of all bone conduction sound bodies 21 to connect the sound emitting ends of the plurality of bone conduction sound bodies 21 to form a sound emitting surface. It should be noted that the number of bone conduction sound bodies 21 connected on the first strip structure 221 is not limited here and can be set according to the actual situation.

[0048] As shown in FIGS. 8 and 9, the connecting unit 22 can also be formed by 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 intersecting connection, wherein the first strip structure 221 is connected with the sound emitting ends of a plurality of bone conduction sound bodies 21 to connect the sound emitting points of the plurality of bone conduction sound bodies 21 to form a sound emitting surface.

[0049] As shown in Fig. 7, the connecting unit 22 can also be formed by 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 structures 222 are connected with the first strip structures 221 and are not directly connected with the sound emitting end of the bone conduction sound emitting body 21. The first strip structures 221 and the second strip structures 222 jointly form the sound emitting surface.

[0050] 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 emitting area and the shape requirement of the adapted soft pack, for example, to adapt to a U-shaped pillow. The shape formed above can have a certain curvature, which is not limited by the present application.

[0051] In actual application, the balanced sound emitting part 2 in the bone conduction sound emitting pad is Y-axis symmetrical, so as to avoid the problem of large sound difference between the left ear and the right ear of the human brain when lying on the back.

[0052] The first strip structure 221 can be made of plastic, wood, metal or other materials having a conductive effect, which is not limited by the present application. Preferably, the Shore hardness of the first strip structure 221 and the second strip structure 222 is greater than 40 HD. 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 can be selected as different materials according to actual conditions.

[0053] When the bottom pad 1 needs to be closed, the bone conduction sound emitting pad further comprises a top pad 4 which is buckled with the bottom pad 1. In order to make the sound emitting 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 not be used.

[0054] As shown in Fig. 10, in order to avoid too large difference in listening feeling when a person lies on the back or directly leans on the soft pack or lies on the side or leans on the side, the bone conduction sound emitting pad further comprises one or two auxiliary sound emitting parts 3 arranged on the bottom pad 1. When the auxiliary sound emitting part 3 is one, the auxiliary sound emitting part 3 is located above or below the Y-axis direction of the balanced sound emitting part 2. When the auxiliary sound emitting part 3 is two or more, the auxiliary sound emitting parts 3 are respectively located above and below the Y-axis direction of the balanced sound emitting part 2. Preferably, when the auxiliary sound emitting part 3 is two or more, the auxiliary sound emitting parts 3 are evenly distributed above and below the Y-axis direction of the balanced sound emitting part 2.

[0055] The auxiliary sound production part 3 includes at least one auxiliary sound production body 31, and the volume outputted by the auxiliary sound production body 31 is greater than the volume outputted by the bone conduction sound production body 21. The specific form of the auxiliary sound production part 3 is designed according to the sound production area requirement. As shown in FIG. 12 and FIG. 13, the structure of the auxiliary sound production body 31 in the auxiliary sound production part 3 can adopt the structure of the prior art, i.e. multiple bone conduction sound production bodies arranged independently. As shown in FIG. 11, the auxiliary sound production part 3 can of course preferably adopt the structure form in the balanced sound production part 2 in the present application, i.e. the auxiliary sound production part 3 further includes an auxiliary connecting unit 32, and the structure of the auxiliary connecting unit 32 is the same as the structure form of the connecting unit 22, which will not be described herein again.

[0056] The input amplitude of the audio signal of the auxiliary sound production body 31 in the auxiliary sound production part 3 distributed above and / or below the Y-axis direction of the balanced sound production part 2 is greater than the input amplitude of the audio signal of the bone conduction sound production body 21 in the balanced sound production part 2, and the positive interval is 1-30 dBV. In this input amplitude interval, the parameters can be adjusted according to the area, thickness and density of the soft package to adapt to the use. When lying on the back or leaning forward, the volume of the auxiliary sound production body 31 in the auxiliary sound production part 3 distributed above and / or below the Y-axis direction of the balanced sound production part 2 is high, and the sound can be transmitted through the air, which makes up for the problem that the brain area protrusion area picks up small sound when bone conduction. When lying on the side or leaning on the side, the tragus landing point is in the balanced sound production part 2, and the ear close to the sound production surface bone side in the balanced sound production part 2 can also block the air conduction sound of the auxiliary sound production body 31 in the auxiliary sound production part 3, and the sound picked up by the tragus mainly comes from the balanced sound production part 2, thereby avoiding the problem of large volume difference between lying on the back (leaning forward) and lying on the side (leaning on the side).

[0057] As shown in FIG. 4, the bone conduction sound emitting pad further comprises a control unit 6 for controlling the working or non-working of the plurality of bone conduction sound emitting bodies 21 and the auxiliary sound emitting bodies 31. In order to effectively reduce power consumption and further avoid the situation of sound leakage, the bone conduction sound emitting pad further comprises a plurality of pressure sensors 7 located on the bottom pad 1, which are distributed in the brain landing area of the bone conduction sound emitting pad. When the pressure value collected by any pressure sensor 7 is greater than the pre-set value, the control unit 6 controls the working of the bone conduction sound emitting bodies 21 in the balanced sound emitting part 2 and the auxiliary sound emitting bodies 31 in the auxiliary sound emitting part 3 corresponding to the position of the pressure sensor 7, and the rest of the bone conduction sound emitting bodies 21 and the auxiliary sound emitting bodies 31 do not work. Among them, the bone conduction sound emitting bodies 21 and the auxiliary sound emitting bodies 31 corresponding to the position of the pressure sensor 7 are the bone conduction sound emitting bodies 21 and the auxiliary sound emitting bodies 31 within the specified range of the pressure sensor 7. That is, the bone conduction sound emitting bodies 21 in the balanced sound emitting part 2 and the auxiliary sound emitting bodies 31 in the auxiliary sound emitting part 3 within the specified range work, and the bone conduction sound emitting bodies 21 in the balanced sound emitting part 2 and the auxiliary sound emitting bodies 31 in the auxiliary sound emitting part 3 in other areas do not work, thereby further solving the problem of large sound difference between left and right ears when the human brain rests on different positions of the soft package, and effectively reducing power consumption and improving the situation of sound leakage. Among them, the specified range is the distance range within the actual landing range of the human brain and the actual landing point of the human brain along the X-axis and Y-axis.

[0058] Among them, the control unit 6 comprises a main shell, a PCB board arranged inside the main shell, and a plurality of keys, a charging port and a signal line arranged outside the main shell, the signal line is connected to the connection line unit 8, and the control unit 6 is powered by the charging port through an external direct current power supply.

[0059] Of course, the control unit 6 is provided with voice and music mode switching to avoid the decline in sound quality caused by the difference in sound wave characteristics of voice and music in the soft package body 5.

[0060] The control unit 6 controls the circuit to automatically cut off the input signal of the bone conduction sound emitting bodies 21 in the balanced sound emitting part 2 and the auxiliary sound emitting bodies 31 in the auxiliary sound emitting part 3 after the call is answered, the audio output is switched to the communication device, and the playback of the bone conduction sound emitting bodies 21 in the balanced sound emitting part 2 and the auxiliary sound emitting bodies 31 in the auxiliary sound emitting part 3 is restored after the call is ended. Among them, the outlet mode of the bone conduction sound emitting pad is the middle of the bottom pad 1, which effectively adapts to the left and right hand use habit when people rest.
