Description

Technical Field

[0001] The utility model relates to the technical field of acoustic devices, in particular to a bone conduction sounding pad and a bone conduction sounding soft package object. Background Art

[0002] At present, soft package sounding is used to enable people to listen to music and voices when attaching to the soft package 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 for accompaniment to sleep, and avoid the ear screen compression and discomfort caused by wearing headphones to listen.

[0003] Existing sounding soft package products generally use two methods: built-in horn speakers and bone conduction. When using built-in horn speakers, there is 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, resulting in poor clarity due to attenuation of low and medium frequencies; in order to distinguish from speakers, an embedded package is used, but there are problems such as difficult maintenance and cleaning. When using bone conduction technology for soft package sounding, the internal filler is used as the sound propagation medium. After being pressed, the density of the medium is unevenly distributed, resulting in a change in the sound propagation speed and causing the sound propagation direction to deflect, thereby causing refraction and reflection of sound waves. At the same time, multiple vibrators are placed in the soft package object, and the sound waves between multiple vibrators will generate interference and diffraction phenomena in the soft package object, resulting in changes in sound intensity and frequency characteristics, causing uneven conduction sound quality and volume and excessive nonlinear distortion.

[0045] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below with reference to the drawings through specific implementation manners.

[0046] Embodiment 1

[0047] As Figure 4 shown, the embodiment of the present utility model provides a bone - conduction sound - emitting pad, which can be applied to a soft package, and the soft package can be a cushion or a headrest.

[0048] The bone conduction sound - generating pad includes a bottom pad 1 and a sound - equalizing generating part 2. The sound - equalizing generating part 2 includes a connecting unit 22 and a plurality of bone conduction sound - generating bodies 21. The connecting unit 22 includes one or more first strip - shaped structures 221, and each of the first strip - shaped structures 221 connects the sound - generating ends of the plurality of bone conduction sound - generating bodies 21 to connect the independent sound - generating ends of the plurality of bone conduction sound - generating bodies 21 to form a sound - generating surface. Since the sound - generating ends of the plurality of bone conduction sound - generating bodies 21 are connected through the connecting unit 22, and then the sound - generating points of the plurality of bone conduction sound - generating bodies 21 are connected to form a sound - generating surface, the sound generation of scattered vibration points is converted into surface sound generation of the sound - generating surface. The sound waves output from the sound - generating points propagate linearly along the connection direction of the first strip - shaped structures 221 in the connecting unit 22, with less refraction and reflection, reducing the interference between sound waves, improving the volume balance, reducing harmonic distortion, and improving the sound quality.

[0049] A plurality of accommodation cavities matching the shapes of the plurality of bone conduction sound - generating bodies 21 are provided in the bottom pad 1. The plurality of bone conduction sound - generating bodies 21 and the plurality of accommodation cavities are arranged in one - to - one correspondence. Preferably, one end away from the sound - generating end of the bone conduction sound - generating body 21 is located in the accommodation cavity. Of course, an accommodation groove matching the first strip - shaped structure 221 is recessed to facilitate installation on the bottom pad 1.

[0050] Among them, in order to reduce the vibration of the end of the bone conduction sound - generating body 21 away from the sound - generating end and reduce the leakage of the bone conduction sound - generating body 21 to the mattress, a damping pad is provided between the bottom end of the bone conduction sound - generating body and the bottom pad. The sound leakage to the bottom - pad carrier (such as a mattress, a sofa pad, etc.) can be reduced by 40%. Preferably, the thickness of the damping pad is greater than 1 mm, and the Shore hardness of the damping pad is greater than 40 HD.

[0051] Preferably, the material of the bottom pad 1 is rubber. Since there is a bottom pad 1 accommodating a plurality of bone conduction sound - generating bodies 21, the problem of sound leakage generated by the vibration of the bone conduction sound - generating bodies 21 is further reduced.

[0052] In this embodiment, the bone conduction sound - generating body 21 includes a bone conduction oscillator and a housing. The bone conduction oscillator is arranged in the housing, and one end face of the housing is the sound - generating end. The first strip - shaped structure 221 is connected to the sound - generating end of the housing in the bone conduction sound - generating body 21. It should be noted that the bone conduction sound - generating body 21 is a prior art and will not be elaborated here. Among them, the connection between the connecting unit and the bone conduction sound - generating body 21 can be achieved in various ways, such as integral molding, fixed connection, or movable connection, as long as it can conduct sound waves well.

[0053] Such as Figure 5 and Figure 6As shown, the connecting unit 22 is formed by one or more first strip-shaped structures 221 arranged along the first direction. When the connecting unit 22 is a first strip-shaped structure 221, the first strip-shaped structure 221 is connected to the sounding ends of all the bone conduction sound emitters 21 to connect the sounding ends of the multiple bone conduction sound emitters 21 to form a sounding surface. Among them, the number of bone conduction sound emitters 21 connected to the first strip-shaped structure 221 is not limited here and is set according to the actual situation.

[0054] As Figure 8 and Figure 9 shown, the connecting unit 22 can also be formed by cross-connecting one or more first strip-shaped structures 221 arranged along the first direction and one or more first strip-shaped structures 221 arranged along the second direction. Among them, the first strip-shaped structure 221 is connected to the sounding ends of the multiple bone conduction sound emitters 21 to connect the sounding points of the multiple bone conduction sound emitters 21 to form a sounding surface.

[0055] As Figure 7 shown, the connecting unit 22 can also be formed by cross-connecting one or more first strip-shaped structures 221 arranged along the first direction and one or more second strip-shaped structures 222 arranged along the second direction. Among them, the second strip-shaped structure 222 is connected to the first strip-shaped structure 221 and is not directly connected to the sounding end of the bone conduction sound emitter 21. The first strip-shaped structure 221 and the second strip-shaped structure 222 jointly form a sounding surface.

[0056] It should be noted that the number of the first strip-shaped structure 221 or the second strip-shaped structure 222 and the shape formed by the connection of the first strip-shaped structure 221 or the second strip-shaped structure 222 are designed according to the sounding area and the shape requirements of the adapted soft package. For example, to adapt to a U-shaped pillow, the formed shape can present a certain arc, which is not limited in the present invention.

[0057] In the actual application process, the balanced sounding part 2 in the bone conduction sounding pad is Y-axis symmetric to avoid the problem of large sound differences between the left and right ears of the human brain when lying on the back.

[0058] The first strip-shaped structure 221 can be made of materials with conduction functions such as plastic, wood, metal, etc., which is not limited in the present invention. Preferably, the Shore hardness of the first strip-shaped structure 221 and the second strip-shaped structure 222 is greater than 40HD. It should be noted that the materials of the first strip-shaped structure 221 and the second strip-shaped structure 222 can be the same, and of course, different materials can be selected according to the actual situation.

[0059] When the bottom pad 1 needs to be closed, the bone conduction sounding pad further includes a top pad 4. The top pad 4 is buckled with the bottom pad 1. To enable the sounding surface to better transmit sound waves, the top pad 4 contacts the connecting unit 22. Of course, when it is not necessary to close the bottom pad 1, the top pad 4 can be not used.

[0060] AsFigure 10 As shown, in order to avoid a too large difference in the listening experience between when a person lies supine or leans directly against the soft package and when lying on the side or leaning on the side, the bone conduction sound - emitting pad further includes one or two auxiliary sound - emitting parts 3 arranged on the bottom pad 1. When there is one auxiliary sound - emitting part 3, the auxiliary sound - emitting part 3 is located above or below the equalizing sound - emitting part 2 in the Y - axis direction. When there are two or more auxiliary sound - emitting parts 3, the auxiliary sound - emitting parts 3 are respectively located above and below the equalizing sound - emitting part 2 in the Y - axis direction. Preferably, when there are two or more auxiliary sound - emitting parts 3, the auxiliary sound - emitting parts 3 are evenly distributed above and below the equalizing sound - emitting part 2 in the Y - axis direction according to the quantity.

[0061] Among them, 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 requirements. For example, Figure 12 and Figure 13 as shown, the structure of the auxiliary sound - emitting body 31 in the auxiliary sound - emitting part 3 can adopt the structure of the existing technology, that is, multiple independently arranged bone conduction sound - emitting bodies. For example, Figure 11 as shown, the auxiliary sound - emitting part 3 can of course preferably adopt the structural form in the equalizing sound - emitting part 2 of the present utility model, that is, the auxiliary sound - emitting part 3 further includes an auxiliary connection unit 32, and the structure of the auxiliary connection unit 32 is the same as the structural form of the connection unit 22, which will not be elaborated here.

[0062] Among them, the input amplitude of the audio signal of the auxiliary sound - emitting body 31 in the auxiliary sound - emitting part 3 distributed above and / or below the equalizing sound - emitting part 2 in the Y - axis direction is larger than that of the bone conduction sound - emitting body 21 in the equalizing sound - emitting part 2. The positive interval is 1 - 30 dBV. Within this input amplitude interval, parameters can be adjusted according to the area, thickness, and density of the soft package to adapt to the use. When lying supine or leaning directly, the volume of the auxiliary sound - emitting body 31 in the auxiliary sound - emitting part 3 distributed above and / or below the equalizing sound - emitting part 2 in the Y - axis direction is high, and it can be transmitted through air conduction, making up for the problem that the sound picked up in the cranial protuberance area during bone conduction is small. When lying on the side or leaning on the side, the tragus landing point is on the equalizing sound - emitting part 2, and the ear close to the sound - emitting surface bone side of the equalizing sound - emitting part 2 can simultaneously block the air - conducted sound of the auxiliary sound - emitting body 31 in the auxiliary sound - emitting part 3. The sound picked up by the tragus mainly comes from the equalizing sound - emitting part 2, thereby avoiding the problem of a large difference in volume between lying supine (leaning directly) and lying on the side (leaning on the side).

[0063] For example, Figure 4As shown in the figure, the bone conduction sound - emitting pad further includes a control unit 6. The control unit 6 is communicatively connected to a plurality of bone conduction sound - emitting bodies 21 and auxiliary sound - emitting bodies 31, and is used to control the plurality of bone conduction sound - emitting bodies 21 and auxiliary sound - emitting bodies 31 to work or not work. To effectively reduce power consumption and further avoid sound leakage, the bone conduction sound - emitting pad further includes a plurality of pressure sensors 7 located on the bottom pad 1. The plurality of pressure sensors 7 are distributed within the area where the human brain lands on the bone conduction sound - emitting pad. The control unit 6 is communicatively connected to the plurality of pressure sensors 7. When the pressure value collected by any one of the pressure sensors 7 is greater than a preset value, the control unit 6 controls 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 to work, and the remaining bone conduction sound - emitting bodies 21 and auxiliary sound - emitting bodies 31 do not work. Among them, the bone conduction sound - emitting bodies 21 and auxiliary sound - emitting bodies 31 corresponding to the position of the pressure sensor 7 are the bone conduction sound - emitting bodies 21 and auxiliary sound - emitting bodies 31 within a specified range from 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 differences between the left and right ears when the human brain leans on the soft package at different positions, effectively reducing power consumption, and improving the sound leakage situation. Among them, the specified range is the range where the human brain actually lands and the distance range within 3 - 5 cm of the human brain's actual landing point extending outward along the X - axis and Y - axis.

[0064] Among them, the control unit 6 includes a main housing, a PCB board arranged inside the main housing, and a plurality of buttons, a charging port, and signal lines arranged outside the main housing. The signal lines are connected to the connection line unit 8, and the control unit 6 is powered by an external DC power supply through the charging port.

[0065] 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 different acoustic wave characteristics of voice and music in the soft package body 5.

[0066] The control unit 6 controls the circuit to automatically cut off the input signals 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 answering an incoming call, and switches the audio output to the communication device. After the call ends, it resumes 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. Among them, the wire - leading - out method of the bone conduction sound - emitting pad is in the exact middle of the bottom pad 1, effectively adapting to the left - hand and right - hand usage habits of people during rest.

[0067] Embodiment Two

[0068] As Figures 1 - 3 shown in the figure, this embodiment provides a bone conduction sound - emitting soft package, which includes a soft package body 5 and the bone conduction sound - emitting pad in Embodiment One. The soft package body 5 can be a backrest or a headrest.

[0069] The bone conduction sound - emitting pad is placed inside or at the outer bottom of the soft - packed object body 5 to support the compressed soft - packed object body 5. As Figure 1 shown, the bone conduction sound - emitting pad is independently placed at the outer bottom of the soft - packed object body 5, and can also be quickly fixed in various forms such as snap - fastening with the soft - packed sleeve 9 of the soft - packed object body 5, or as Figure 2 shown, the bone conduction sound - emitting pad can also be installed inside the soft - packed object body 5, or as Figure 3 shown, the bone conduction sound - emitting pad is installed between the soft - packed object body 5 and the soft - packed sleeve 9.

[0070] As Figure 11 shown, according to the tragus landing point when a person lies on their side or leans against the soft - packed object body 5, the soft - packed object body 5 is divided into an A area 51, a B area 52, and a C area 53 arranged in sequence along the Y - axis direction. The Y - axis length of the B area 52 is centered on the horizontal line where the tragus landing point is located. The equalizing sound - emitting part 2 is located in the B area 52, and the auxiliary sound - emitting part 3 is located in the A area 51 and / or the C area 53. Among them, the B area 52 is the tragus landing point area. Preferably, the range of the Y - axis length in the B area 52 is about 10 cm above and below the horizontal center line of the tragus, and the range of the X - axis length is the length of the entire soft - packed object body 5.

[0071] As Figure 12 shown, the soft - packed object body 5 further includes a D area 54, which is the range of the human brain landing point pressure - receiving position. The pressure sensor 7 is located in the D area 54. Preferably, the range of the Y - axis length in the D area 54 is about 20 cm above and below the horizontal center line of the tragus, and the range of the X - axis length is the length of the entire soft - packed object body 5. As Figure 13 shown, the soft - packed object body 5 further includes an E area 55, and the E area 55 is the range where the actual human brain landing point is located and the distance range within 3 - 5 cm of the outward expansion of the actual human brain landing point along the X - axis and Y - axis.

[0072] The sound - emitting pad is placed inside or at the outer bottom of the soft - packed object body 5. The bone conduction sound - emitting pad has a certain hardness and can play a certain supporting role for the compressed soft - packed object body 5. Furthermore, when it is placed inside or at the outer bottom of the soft - packed object body 5, it can support the soft - packed object body 5 and reduce the deformation of the soft - packed object body 5 when it is compressed, and alleviate the deformation of the filling material inside the soft - packed object body 5 after it is stressed, further improving the sound quality. At the same time, since the amplitudes and phases of the bone conduction sound - emitting bodies 21 of the equalizing sound - emitting part 2 in the bone conduction sound - emitting pad are the same, and the multiple bone conduction sound - emitting bodies 21 are connected by a connection unit 22 with a uniform density, the sound wave superposition enhancement effect is realized, and the refraction of sound waves in the deformed soft - packed object body 5 is avoided.
