Description
Technical Field
The invention relates to the field of acoustics, in particular to a loudspeaker with an acoustic wave steering structure, an acoustic wave steering structure and an acoustic effect reproduction method thereof.
Background
A speaker is a device capable of converting an audio signal into sound to achieve sound reproduction, and typically, the speaker includes more than one speaker, for example, when the number of speakers exceeds two, each speaker of the speaker needs to be arranged according to an acoustic principle so that the speaker provides stereo sound as much as possible to meet the listening requirements of a listener. It will be appreciated by those skilled in the art that since the direction of sound production of each loudspeaker is highly deterministic, if a loudspeaker is intended to provide stereo sound, the location where each loudspeaker is arranged requires a professional to arrange according to acoustic principles and also requires the cooperation of a plurality of loudspeakers to enable reproduction of stereo sound, whereas when a plurality of loudspeakers cooperate to provide stereo sound, the location and relative angle of adjacent loudspeakers need to be arranged according to acoustic principles, which results in loudspeakers of relatively large size and inconvenient movement. Since it is difficult for the average consumer to grasp the knowledge in terms of acoustics, although the positions where the individual speakers of the speakers are arranged are not changed during the movement of the speakers, and the distance and the relative angle between the adjacent speakers are required to be arranged by the average consumer, it is apparent that the average consumer cannot correctly determine the distance and the relative angle between the adjacent speakers due to lack of knowledge in terms of acoustics, so that the combination of the speakers cannot provide a good sound quality effect, which affects not only the listening effect of the average consumer, but also the sound quality of the speakers is adversely affected by the average consumer.
In addition, since the horn of the speaker has a sound emission specificity with a strong directivity, when the speaker is applied in a room, for example, when the speaker is applied in a room as a conference room, the speaker is generally installed obliquely at a top corner position of the room, and the diaphragm of the horn of the speaker is obliquely directed downward toward the middle of the room, so that sound reproduced by the speaker can be diffused throughout the room. Obviously, on the one hand, there is no choice for the location where the speaker is installed, on the other hand, since the volume and size of the speaker are relatively large, the difficulty of installation is relatively large when the speaker is installed at the top corner of the room, and the safety of the speaker cannot be effectively ensured. In addition, speakers installed at the top corners of a room may seriously affect the beauty of the room, especially the beauty of the room being used as a conference room.
In a small speaker, since the speaker of the speaker has a sound emission characteristic with relatively high directivity, only a listener located at the center axis of the speaker can enjoy the sound quality of the sound reproduced by the speaker, while a listener located at the center axis of the speaker cannot enjoy the sound quality of the sound reproduced by the speaker. However, in most cases, when the speaker of the speaker reproduces sound, most listeners are offset from the central axis of the speaker, and therefore, how to allow these listeners offset from the central axis of the speaker to enjoy good sound quality brought by the speaker is a technical problem that the inventors have made an effort to solve.
In addition, sound reproduced by a speaker's horn is particularly sensitive to external vibrations and fluctuations, and particularly for a midrange horn and a tweeter, the higher the audio frequency band, the more susceptible the speaker to external fluctuations or vibrations, for example, if sound or fluctuations generated by other sound sources radiate in the direction of the tweeter during sound reproduction by the speaker's tweeter, sound waves generated by the tweeter are inevitably disturbed, resulting in deterioration of sound effects. Therefore, it is another technical problem the inventors have sought to solve how to prevent the sound reproduced by the speaker of the speaker from being disturbed by external vibration or fluctuation to ensure the sound quality effect of the sound reproduced by the speaker of the speaker.

Detailed Description
The technical solution of the present invention is specifically described below according to the claims and disclosure of the present invention.
It will be appreciated by those skilled in the art that in the present disclosure, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. refer to an orientation or positional relationship based on that shown in the drawings, which is merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms should not be construed as limiting the present invention.
It will be understood that the terms "a" and "an" should be interpreted as referring to "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, while in another embodiment, the number of elements may be plural, and the term "a" should not be interpreted as limiting the number.
Fig. 1 to 4 of the drawings, which are drawings, illustrate and describe a speaker with a sound wave turning structure according to a preferred embodiment of the present invention, wherein the speaker includes a sound emitting part 10 and a sound wave turning structure 20 and has a radiation passage 30, wherein the sound wave turning structure 20 is disposed in a sound wave emitting direction of the sound emitting part 10, and the radiation passage 30 is formed between the sound wave turning structure 20 and the sound emitting part 10, and the radiation passage 30 communicates with the outside of the speaker.
When the sound wave generated by the sound generating part 10 in response to the input of the audio signal is radiated to the sound wave turning structure 20, the radiation direction of the sound wave is changed by being blocked by the sound wave turning structure 20, and the sound wave with the radiation direction changed is further radiated to the outside of the speaker via the radiation channel 30 to generate sound, in such a manner that a listener located around the central axis of the speaker can enjoy good sound quality of the sound reproduced by the speaker in response to the audio signal. In other words, when the sound wave generated by the sound generating part 10 in response to the audio signal is radiated to the sound wave diverting structure 20, the sound wave diverting structure 20 can eject the sound wave to the outside of the speaker through the radiation passage 30 and change the radiation direction of the sound wave.
Further, referring to fig. 1 to 4, the sound wave steering structure 20 includes a steering part 21, wherein the steering part 21 is held in the sound wave emitting direction of the sound emitting part 10, and the radiation passage 30 is formed between the steering part 21 and the sound emitting part 10, so that after the sound wave generated by the sound emitting part 10 is radiated to the steering part 21, the sound wave can be changed in radiation direction by being blocked by the steering part 21, and the sound wave after changing the radiation direction is further radiated to the outside of the speaker through the radiation passage 30 to generate sound, that is, the steering part 21 can eject the sound wave to the outside of the speaker through the radiation passage 30.
Referring to fig. 1 to 4, the sound generating part 10 has a diaphragm 11, the turning part 21 has a first turning surface 211, wherein the first turning surface 211 is a spherical turning surface, wherein the turning part 21 is disposed such that the first turning surface 211 faces the diaphragm 11 of the sound generating part 10, thereby forming the radiation passage 30 of the speaker between the diaphragm 11 of the sound generating part 10 and the first turning surface 211 of the turning part 21.
When the sound generating part 10 responds to an audio signal, the diaphragm 11 of the sound generating part 10 can be acted on by a magnetic return system of the sound generating part 10 to generate sound waves, the steering part 21 is kept in the sound wave emitting direction of the sound generating part 10, and the first steering surface 211 of the steering part 21 faces the diaphragm 11 of the sound generating part 10, so that the sound waves generated by the diaphragm 11 due to the air being blown are radiated towards the first steering surface 211 of the steering part 21, after encountering the first steering surface 211 of the steering part 21, the sound waves can be changed in direction due to being blocked by the first steering surface 211 of the steering part 21, and the sound waves after steering can be radiated to the outside of the loudspeaker from the radiation channel 30 to generate sound.
It should be noted that the type of the sound generating unit 10 is not limited in the speaker of the present invention, and for example, the sound generating unit 10 may be implemented as a horn such as, but not limited to, a tweeter, a mid-woofer, a subwoofer, a woofer, a full-range horn, etc., as long as it is capable of reproducing sound corresponding to an audio signal after responding to input of the audio signal. It is understood that when the sound emitting part 10 is implemented as a horn, the diaphragm 11 of the sound emitting part 10 may be implemented as a paper of the horn, so that when the sound emitting part 10 responds to an input of an audio signal, the diaphragm 11 may be driven to generate sound waves due to the air being blown, and since the turn part 21 is held in the sound emitting direction of the sound emitting part 10, and the first turn surface 211 of the turn part 21 is directed toward the diaphragm 11 of the sound emitting part 10, sound waves generated by the air being blown by the diaphragm 11 of the sound emitting part 10 may be radiated to the first turn surface 211 of the turn part 21, and at this time, the first turn surface 211 of the turn part 21 may change a radiation direction of sound waves due to blocking sound waves, and the sound waves after being changed in radiation direction may be further radiated to the outside of the speaker through the radiation passage 30 formed between the first turn surface 211 of the turn part 21 and the diaphragm 11 of the sound emitting part 10.
Preferably, the first turning surface 211 of the turning part 21 is a spherical turning surface, and correspondingly, the diaphragm 11 of the sound emitting part 10 is a spherical diaphragm, in such a way that the uniformity of the radiation passage 30 formed between the first turning surface 211 of the turning part 21 and the diaphragm 11 of the sound emitting part 10 can be ensured to ensure the uniformity of the sound wave radiated from the speaker in each direction, and in such a way that the speaker allows a listener to listen to the sound reproduced by the speaker from different angles with uniform and good sound quality.
More preferably, the diaphragm 11 of the sound generating part 10 may be a concave diaphragm such that the diaphragm 11 of the sound generating part 10 forms a holding space 12 by being concaved, wherein the turn part 21 may be held in the holding space 12 of the sound generating part 10, and the radiation passage 30 is formed between the first turn surface 211 of the turn part 21 and the diaphragm 11 of the sound generating part 10. Specifically, the diaphragm 11 of the sound generating portion 10 is a concave spherical diaphragm, and the first steering surface 211 of the steering portion 21 is a convex spherical steering surface, so that the speaker can have a wider diffusion angle, so that the speaker can provide a better sound effect in a wider range.
It is worth mentioning that the opening of the radiation passage 30 formed between the first diverting surface 211 of the diverting part 21 and the diaphragm 11 of the sound generating part 10 surrounds the diverting part 21, so that the speaker allows sound waves, which are changed in radiation direction, to radiate to the outside of the speaker around the diverting part 21, i.e., the speaker is capable of radiating sound waves in all directions. In other words, the speaker can radiate sound waves in a 360 ° direction, so that the speaker can provide stereo sound. It will be appreciated by those skilled in the art that the loudspeaker of the present invention is capable of providing stereo sound by a single sound generating portion 10 and is 360 ° surround stereo sound, which is unexpected in the prior art, and that the loudspeaker of the present invention is particularly important for improving the sound effect of the loudspeaker by providing 360 ° surround stereo sound. In other words, in the speaker of the present invention, the speaker can realize a 360 ° surround sound by maintaining one of the turning parts 21 in the sound wave emitting direction of one of the sound emitting parts 10, which is unexpected in the speaker of the related art. In addition, the speaker of the present invention realizes a 360 ° surround sound by means of the one turn portion 21 being maintained in the sound wave emitting direction of one sound emitting portion 10, which makes the speaker of the present invention simple in structure, small in size, convenient to be carried and advantageous in reducing the manufacturing cost of the speaker.
In addition, since the diaphragm 11 of the sound generating part 10 is a concave spherical diaphragm and the first diverting surface 211 of the diverting part 21 is a convex spherical diverting surface, the radiation passage 30 formed between the diaphragm 11 of the sound generating part 10 and the first diverting surface 211 of the diverting part 21 has good uniformity in all directions, so that sound emitted from the speaker to all directions via the radiation passage 30 is complete, and the speaker can provide uniform sound with good sound effects in all directions around.
In addition, the speakers are capable of providing 360 ° surround sound so that a listener can listen to sound emitted by the speakers at any one of the speakers. And the speaker is adapted to be moved and placed in any position for use after the speaker is moved, the speaker is capable of providing 360 ° surround sound.
The listener may also symmetrically arrange the two loudspeakers so that the two loudspeakers create a stereo sound field, so that the two loudspeakers allow the listener to obtain a better hearing enjoyment. Because the loudspeakers are capable of providing 360 ° surround sound, a listener without any acoustic basis can also obtain a stereo sound field by placing two of the loudspeakers symmetrically. More importantly, in the speaker of the present invention, the stereo sound field is formed by two speakers capable of providing 360 ° surround stereo sound, and compared with the stereo sound field obtained by combining a plurality of common speakers in the prior art, the listener can obtain the feeling of being in the scene by the stereo sound field provided by two speakers of the present invention when listening to the sound effect.
Referring to fig. 12A and 12B, each of the speakers of the present invention can provide 360 ° surround sound, and because each of the speakers has a wide spread angle, when a listener symmetrically places the two speakers, the two speakers can form a real stereo sound field, so that an immersive sensation can be obtained when the listener listens to sound effects in the stereo sound field formed by the two speakers. For example, in the specific example disclosed in fig. 12A, the curves a and b are curves formed by sound waves emitted from one sound emitting point of the speaker in different directions after being deflected by the first deflection surface 211 of the deflection unit 21, and the content of the speaker of the present invention is described in a conceptual manner, but the curves a and b should not be taken as limitations on the content and scope of the speaker of the present invention by those skilled in the art. It follows that when two of the loudspeakers are used in conjunction with each other, the surround sound formed by the two loudspeakers has an area of intersection which is capable of forming a stereo sound field to provide a better sound effect for a more audience.
It is worth mentioning that the curvature of the first diverting surface 211 of the diverting part 21 and the curvature of the diaphragm 11 of the sound-emitting part 10 may be identical, and in other examples of the speaker of the present invention, the curvature of the first diverting surface 211 of the diverting part 21 and the curvature of the diaphragm 11 of the sound-emitting part 10 may be not identical, so that the speaker allows the size of the radiation passage 30 formed between the first diverting surface 211 of the diverting part 21 and the diaphragm 11 of the sound-emitting part 10 to be gradually increased from the inside to the outside, in such a way that the diffusion angle of the speaker can be increased, and the sound quality effect of sound reproduced by the speaker can be further improved. When the sounding part 10 generates sound waves in response to input of an audio signal, the first diverting surface 211 of the diverting part 21 and the diaphragm 11 of the sounding part 10 can guide the radiation direction of the sound waves whose radiation direction is changed, and by gradually increasing the size of the radiation passage 30 formed between the first diverting surface 211 of the diverting part 21 and the diaphragm 11 of the sounding part 10 from the inside to the outside, the range in which the sound waves generated by the sounding part 10 in response to input of an audio signal are radiated to the outside of the speaker through the radiation passage 30 can be expanded to spread the sound waves in a larger range.
Specifically, referring to fig. 4, the radiation passage 30 has an inner side end 31 and an open end 32 corresponding to the inner side end 31, wherein the inner side end 31 of the radiation passage 30 is close to the central axis of the sound generating part 10, the open end 32 of the radiation passage 30 communicates with the outside of the speaker, wherein the size of the radiation passage 30 gradually increases from the inner side end 31 toward the open end 32, in such a manner that not only the radiation direction of the sound wave after being changed in radiation direction but also the dispersion angle of the speaker can be further increased, thereby enabling the speaker to disperse the sound wave in a larger range. For example, the radiation passage 30 may have a cross-sectional shape that is, but not limited to, a substantially "snail shell" or "trumpet".
In other words, the first diverting surface 211 of the diverting portion 21 can be used not only to change the radiation direction of the sound wave generated by the diaphragm 11 of the sound generating portion 10, but also the first diverting surface 211 of the diverting portion 21 and the diaphragm 11 of the sound generating portion 10 can guide the radiation direction of the sound wave after being changed in the radiation direction in a mutually mating manner.
That is, after the sound wave generated by the sound generating part 10 in response to the input of the audio signal is radiated to the first diverting surface 211 of the diverting part 21, the radiation direction can be changed due to the blockage by the first diverting surface 211 of the diverting part 21, and the sound wave after being changed in radiation direction can be radiated from the inner side end 31 of the radiation passage 30 toward the open end 32 and radiated to the outside of the speaker through the open end 32, thereby reproducing sound. It can be understood that when the sound wave whose radiation direction is changed radiates in the radiation passage 30, the first diverting surface 211 of the diverting portion 21 and the diaphragm 11 of the sound generating portion 10 forming the radiation passage 30 can guide the radiation direction of the sound wave whose radiation direction is changed.
In addition, it will be understood by those skilled in the art that the curvature of the first diverting surface 211 of the diverting portion 21 and the curvature of the diaphragm 11 of the sound-emitting portion 10 also affect the sound effect of the sound reproduced by the speaker, and thus the diverting portion 21 and the diaphragm 11 of the sound-emitting portion 10 having different curvatures may be designed and provided as needed. In addition, in a specific example of the speaker, the first diverting surface 211 of the diverting portion 21 and the diaphragm 11 of the sound generating portion 10 may each be a smooth spherical surface. In yet another specific example of the speaker, at least one of the first diverting surface 211 of the diverting part 21 and the diaphragm 11 of the sound emitting part 10 may be provided with a groove or protrusion of a specific shape to adjust the quality of sound reproduced by the speaker.
Referring to fig. 4, the steering part 21 has a second steering surface 212, wherein the second steering surface 212 of the steering part 21 corresponds to the first steering surface 211 of the steering part 21, that is, the second steering surface 212 and the first steering surface 211 of the steering part 21 are in a back-to-back state, wherein when an external sound wave is radiated toward the speaker, the external sound wave can be radiated only to the second steering surface 212 of the steering part 21, and after the external sound wave is radiated to the second steering surface 212 of the steering part 21, the radiation direction of the external sound wave can be changed due to being blocked by the steering part 21, in such a manner that the interference of the external sound wave to the sound wave generated by the speaker in response to the input of the audio signal can be avoided, thereby ensuring the sound quality and the pureness of the sound reproduced by the speaker.
It should be noted that the second steering surface 212 of the steering portion 21 may be a planar steering surface, or may be a cambered steering surface, for example, but not limited to, a spherical steering surface, and the speaker of the present invention is not limited in this respect.
It should be noted that, when the second turning surface 212 of the turning portion 21 is a cambered turning surface, the curvature of the second turning surface 212 of the turning portion 21 and the curvature of the first turning surface 211 may or may not be identical, and the speaker of the present invention is not limited in this respect.
It is also worth mentioning that although in this particular example of the loudspeaker shown in fig. 4 the direction of extension of the first diverting surface 211 of the diverting part 21 is opposite to the direction of extension of the second diverting surface 212, for example in this particular example shown in fig. 4 the first diverting surface 211 of the diverting part 21 is convex downwards in a direction towards the diaphragm 11 of the sound generating part 10 and the second diverting surface 212 of the diverting part 21 is convex upwards in a direction away from the diaphragm 11 of the sound generating part 10. In other possible examples of the speaker, the extending direction of the first turning surface 211 and the extending direction of the second turning surface 212 of the turning portion 21 may be identical.
Referring to fig. 1 to 4, the steering portion 21 includes a proximal portion 213, a distal portion 214, and a connecting portion 215, wherein proximal and distal sides of the connecting portion 215 extend to be connected to the proximal portion 213 and the distal portion 214, respectively, wherein the proximal portion 213 of the steering portion 21 forms the first steering surface 211, and the distal portion 214 of the steering portion 21 forms the second steering surface 212. The proximal portion 213 of the turn-around portion 21 is close to the diaphragm 11 of the sound generating portion 10, and the first turn-around surface 211 formed by the proximal portion 213 of the turn-around portion 21 is directed towards the diaphragm 11 of the sound generating portion 10, thereby forming the radiation passage 30 between the first turn-around surface 211 of the turn-around portion 21 and the diaphragm 11 of the sound generating portion 10, wherein the distal portion 214 of the turn-around portion 21 is remote from the diaphragm 11 of the sound generating portion 10.
In one example of the speaker of the present invention, the proximal portion 213, the distal portion 214, and the connection portion 215 of the steering portion 21 may be formed separately, and then the proximal portion 213, the connection portion 215, and the distal portion 214 of the steering portion 21 may be formed into the steering portion 21 after the proximal portion 213 and the distal portion 214 are mounted to the connection portion 215, respectively. In another example of the speaker of the present invention, the proximal portion 213, the connecting portion 215, and the distal portion 214 of the steering portion 21 are preferably integrally formed.
Referring to fig. 1 to 4, the acoustic wave steering structure 20 further includes a holding portion 22, wherein the steering portion 21 is disposed at the holding portion 22, and the steering portion 21 is held in the acoustic wave emitting direction of the sounding portion 10 by the holding portion 22.
Specifically, the holding portion 22 includes at least one holding arm 221, wherein the holding arm 221 has an inner connecting end 2211 and an outer connecting end 2212 corresponding to the inner connecting end 2211, wherein the inner connecting end 2211 of the holding arm 221 is connected to the steering portion 21, or the inner connecting end 2211 of the holding arm 221 integrally extends to the steering portion 21, and the outer connecting end 2212 of the holding arm 221 may be provided to a frame of the sound generating portion 10 or other structures, for example, the outer connecting end 2212 of the holding arm 221 may be provided to other structures of the sound wave steering structure 20, and a connection relationship between the outer connecting end 2212 of the holding arm 221 and other structures of the sound wave steering structure 20 will be described later. In this way, the holding arm 221 of the holding portion 22 can stably and reliably hold the turning portion 21 in the sound wave emission direction of the sound emitting portion 10. Preferably, the number of the holding arms 221 of the holding portion 22 may be implemented as two, in which two of the holding arms 221 are symmetrical to each other, in such a manner that the turning portion 21 can be stably and reliably held in the sound wave emitting direction of the sound emitting portion 10. In this specific example of the speaker shown in fig. 2, the two holding arms 221 are center-symmetrical, so that the two holding arms 221 can stably and reliably hold the turning portion 21 in the sound wave emitting direction of the sound emitting portion 10 by fixing the turning portion 21 on opposite sides of the turning portion 21. However, it will be appreciated by those skilled in the art that in other possible examples of the loudspeaker, the two retaining arms 221 may also be axisymmetrical.
It can be understood that, after each of the holding arms 221 of the holding portion 22 holds the turn portion 21 in the sound wave emission direction of the sound emitting portion 10, the radiation passage 30 is provided between the first turn surface 211 of the turn portion 21 and the diaphragm 11 of the sound emitting portion 10 for the sound wave generated by the sound emitting portion 10 in response to the audio signal to be radiated to the outside of the speaker via the radiation passage 30.
It should be noted that the size of the radiation channel 30 affects the sound effect of the speaker, that is, the distance between the first turning surface 211 of the turning part 21 and the diaphragm 11 of the sound generating part 10 affects the sound effect of the speaker. Referring to fig. 4, in this specific example of the speaker of the present invention, a distance parameter set between the diaphragm 11 and the first turning surface 211 of the turning portion 21 in the direction of the central axis of the speaker is L, where the value range of the parameter L is: l is more than or equal to 1mm and less than or equal to 20mm. Preferably, the range of values of the parameter L is: l is more than or equal to 1.5mm and less than or equal to 5mm. More preferably, the parameter L is 2mm, 3mm or 4mm. In addition, the opening size of the diaphragm 11 and the diameter size of the turning portion 21 also affect the sound effect of the speaker, referring to fig. 4, let the opening size parameter of the diaphragm 11 be D, let the diameter size parameter of the turning portion 21 be D, where the ratio range of the opening size parameter D of the diaphragm 11 and the diameter size parameter D of the turning portion 21 is: D/D is more than or equal to 0.3 and less than or equal to 0.7.
In other examples of the speaker shown in fig. 6A, the number of the holding arms 221 of the holding portion 22 may be implemented as three, in which the distances between adjacent two of the holding arms 221 are the same, in such a manner that the holding portion 22 can further stably and reliably hold the turning portion 21 in the sound wave emitting direction of the sound emitting portion 10. In other examples of the speaker shown in fig. 6B, the number of the holding arms 221 of the holding portion 22 may be implemented as four or more, wherein when the number of the holding arms 221 of the holding portion 22 is implemented as four, the distances between adjacent two of the holding arms 221 are the same, by which the holding portion 22 can further stably and reliably hold the turning portion 21 in the sound wave emission direction of the sound emitting portion 11.
In addition, in one example of the speaker shown in fig. 2, each of the holding arms 221 of the holding portion 22 extends to be curved, respectively, and preferably, the curvature and the bending direction of each of the holding arms 221 are identical. In another example of the speaker shown in fig. 6C, each of the holding arms 221 of the holding portion 22 may also extend straight.
In these examples of the speaker shown in fig. 6D and 6E, both end portions of each of the holding arms 221 of the holding portion 22 may be respectively extended and connected to a frame or other structure of the sound emitting portion 10, and the turning portion 21 may be connected to a middle portion of each of the holding arms 221 of the holding portion 22 in such a manner that the turning portion 21 is held in the sound wave emitting direction of the sound emitting portion 10 by each of the holding arms 221. For example, in this specific example of the speaker shown in fig. 6D, the number of the holding arms 221 of the holding portion 22 may be implemented as three, wherein both end portions of each holding arm 221 may be respectively extended and connected to a frame or other structure of the sound generating portion 10, and the end portions of two adjacent holding arms 221 are connected to the same position of the frame or other structure of the sound generating portion 10, so that the three holding arms 221 form an equilateral triangle shape, and the turning portion 21 has three connection points 210 for being connected to the middle portion of each holding arm 221, in such a manner that the turning portion 21 can be held in the sound wave emitting direction of the sound generating portion 10 by each holding arm 221 of the holding portion 22. For another example, in this specific example of the speaker shown in fig. 6E, the number of the holding arms 221 of the holding portion 22 may be implemented as four, in which any corresponding two of the holding arms 221 are parallel to each other, any adjacent two of the holding arms 221 are perpendicular to each other, and both end portions of each of the holding arms 221 may be respectively extended and connected to the frame or other structure of the sound generating portion 10, in which the number of the connection points 210 of the turning portion 21 is four, and the turning portion 21 is respectively connected to the middle portion of each of the holding arms 221 at each of the connection points 210, in such a manner that the turning portion 21 can be held in the sound wave emitting direction of the sound generating portion 10 by each of the holding arms 221 of the holding portion 22. While in other examples of the speakers shown in fig. 6F and 6G, each of the retaining arms 221 of the retaining portion 22 may also have a "U" shape or an inverted "U" shape, respectively.
Referring to fig. 4, in one example of the speaker, the proximal portion 213, the distal portion 214, and the connection portion 215 of the turn portion 21 are integrally formed, and the turn portion 21 is in a solid sphere shape. In other words, the turning portion 21 is a solid sphere. In another specific example of the speaker shown in fig. 7A, the turning portion 21 may be implemented as a hollow sphere. In another specific example of the speaker shown in fig. 7B, the steering portion 21 may be in a shape of an oblate spheroid, such as a rugby ball, it being understood that in this specific example of the speaker shown in fig. 7B, the steering portion 21 may be solid or hollow, and the speaker of the present invention is not limited in this respect.
In another specific example of the speaker shown in fig. 7C, the turn portion 21 further has an annular peripheral wall 216, wherein the peripheral wall 216 extends proximally and outwardly to connect to the first turn surface 211 and the second turn surface 212, respectively. For example, the peripheral wall 216 of the turning portion 21 may be formed by the connecting portion 215. In addition, it should be noted that the cross-sectional shape of the peripheral wall 216 may have a curvature or may be flat, and the speaker of the present invention is not limited in this respect. Of course, those skilled in the art will also appreciate that in this particular example of the speaker shown in fig. 7C, the diverter 21 may be hollow or solid.
In addition, in one example of the speaker of the present invention, the material of the steering part 21 may be a carbon fiber material, and thus, the steering part 21 is a carbon fiber ball, and in another example of the speaker of the present invention, referring to fig. 7D, the steering part 21 includes a steering body 201 and a coating layer 202 coated on an outer surface of the steering body 201, wherein the coating layer 202 is used to form the first steering surface 211 and/or the second steering surface 212. Preferably, the material of the coating 202 may be, but is not limited to, carbon fiber.
Fig. 8A and 8B show schematic sectional views of another variant embodiment of the loudspeaker, unlike the loudspeaker shown in fig. 1 to 4, in this variant embodiment of the loudspeaker shown in fig. 8A and 8B the diaphragm 11 of the sound-generating part 10 is convex, i.e. the diaphragm 11 of the sound-generating part 10 is an upwardly convex diaphragm, so that the direction of extension of the diaphragm 11 of the sound-generating part 10 is opposite to the direction of extension of the first turn surface 211 of the turn part 21. However, as will be understood by those skilled in the art, the curvature of the diaphragm 11 of the sound generating part 10 and the curvature of the first diverting surface 211 of the diverting part 21 may or may not be identical, and the speaker of the present invention is not limited in this respect.
With continued reference to fig. 1 to 4, the speaker includes a mounting unit 40, wherein the sound generating part 10 and the sound wave steering structure 20 are respectively provided to the mounting unit 40 so that the sound generating part 10 and the sound wave steering structure 20 are integrated by the mounting unit 40, and the sound wave steering structure 20 is held in the sound wave emitting direction of the sound generating part 10 by the mounting unit 40.
The sonic steering structure 20 further includes an annular guide portion 23, wherein the guide portion 23 is disposed at the mounting unit 40 such that the sonic steering structure 20 is disposed at the mounting unit 40, and the guide portion 23 is held at the open end 32 of the radiation passage 30 such that the guide portion 23 surrounds the steering portion 21. Alternatively, the guide portion 23 may also be integrally extended to the mounting unit 40, so that the acoustic wave steering structure 20 is provided to the mounting unit 40, and the guide portion 23 is held at the open end 32 of the radiation passage 30. The guide portion 23 has an arcuate guide surface 231, wherein the guide surface 231 of the guide portion 23 extends from the diaphragm 11 of the sound generating portion 10. It will be appreciated by those skilled in the art that in this particular example of the loudspeaker of the invention, the guide surface 231 of the guide portion 23 and the diaphragm 11 of the sound-generating portion 10 are not continuous. The guide surface 231 of the guide part 23 is used to guide the radiation direction of the sound wave radiated from the radiation passage 30 to the outside of the speaker. It will be appreciated by those skilled in the art that the curvature of the guide surface 231 of the guide 23 affects the sound emission range of the speaker, and thus, by providing the guide 23 with the guide surface 231 having an appropriate curvature, the speaker can be made to have different range ranges.
With further reference to fig. 4, the mounting unit 40 further comprises a mounting body 41 and a mounting ring 42, wherein the mounting body 41 has a mounting space 411, wherein the sound generating part 10 is mounted to the mounting ring 42 such that the mounting ring 42 is sleeved outside the sound generating part 10, wherein the mounting ring 42 is mounted to the mounting body 41, and a body portion of the sound generating part 10 is held in the mounting space 411 of the mounting body 41 while leaving only the diaphragm 11 of the sound generating part 10 exposed outside. The guide portion 23 of the acoustic wave turning structure 20 is mounted to the mounting ring 42 of the mounting unit 40 such that the turning portion 21 is held in the acoustic wave emitting direction of the acoustic generating portion 10, and the first turning surface 211 of the turning portion 21 is directed toward the diaphragm 11 of the acoustic generating portion 10, thereby forming the radiation passage 30 between the first turning surface 211 of the turning portion 21 and the diaphragm 11 of the acoustic generating portion 10.
It should be noted that, although in the specific example of the speaker shown in fig. 4, the extending direction of the guide surface 231 of the guide portion 23 is opposite to the extending direction of the diaphragm 11 of the sound generating portion 10, it should be understood by those skilled in the art that in other examples, the extending direction of the guide surface 231 of the guide portion 23 may be identical to the extending direction of the diaphragm 11 of the sound generating portion 10, which is selected and designed according to the needs of the speaker.
The outer connection end 2212 of each of the extension arms 221 of the holding portion 22 is extended outwardly to be connected to the guide portion 23, respectively, in such a manner that the turning portion 21 can be held in the sound wave emitting direction of the sound emitting portion 10. It is worth mentioning that each of the extension arms 221 of the holding portion 22 has good rigidity and inertness, and when the sound wave generated by the sound generating portion 10 in response to the audio signal is radiated to the first turning surface 211 of the turning portion 21, each of the holding arms 221 of the holding portion 22 prevents the turning portion 21 from being displaced relative to the diaphragm 11 of the sound generating portion 10, so as to avoid that the turning portion 21 interferes with the sound quality of the sound reproduced by the speaker due to the displacement relative to the diaphragm 11 of the sound generating portion 10. For example, when the sound wave generated by the sound emitting portion 10 in response to the audio signal is radiated to the first diverting surface 211 of the diverting portion 21, the diverting portion 21 has a tendency to move away from the diaphragm 11 of the sound emitting portion 10 due to the force, and at this time, each of the holding arms 221 of the holding portion 22 can pull the diverting portion 21 to prevent the diverting portion 21 from being displaced away from the diaphragm 11 of the sound emitting portion 10, so that the relative position of the diaphragm 11 of the sound emitting portion 10 of the diverting portion 21 is kept unchanged.
In addition, when the sound wave generated by the sound generating unit 10 in response to the audio signal is radiated to the first steering surface 211 of the steering unit 21, the steering unit 21 does not vibrate, and in this way, it is possible to prevent the steering unit 21 from interfering with the sound quality of the sound reproduced by the speaker due to the vibration, so that the sound effect purity of the sound reproduced by the speaker can be ensured. For example, when the sound wave generated by the sound generating unit 10 is radiated to the first turning surface 211 of the turning unit 21 so that the turning unit 21 has the diaphragm 11 far from the sound generating unit 10, the sound wave of the external environment is radiated to the second turning surface 212 of the turning unit 21 at the same time so that the turning unit 21 has the diaphragm 11 near the sound generating unit 10, at this time, the driving force of the sound wave generated by the sound generating unit 10 acting on the turning unit 21 and the driving force of the sound wave of the external environment acting on the turning unit 21 cancel each other, and the turning unit 21 is kept stationary, so that the noise of the speaker is avoided.
Fig. 5A to 5C show a state when the speaker is applied, in which the sound generating part 10 of the speaker can be connected to a sound source by a wired or wireless connection, in which the sound source can supply an audio signal, the sound generating part 10 can generate a sound wave by driving air through the diaphragm 11 in response to an input of the audio signal, the sound wave can be deflected by being blocked by the first deflecting surface 211 of the deflecting part 21 after being radiated to the first deflecting surface 211 of the deflecting part 21, in which the deflected sound wave can enter the radiation passage 30 from the inner side end 31 of the radiation passage 30, and can radiate to the outside of the speaker from the opening end 32 of the radiation passage 30, in which the diaphragm 11 of the sound generating part 10, the first deflecting surface 211 of the deflecting part 21, and the guide surface 231 of the guide part 23 can guide a radiation direction of the deflected sound wave. That is, the first diverting surface 211 of the diverting portion 21 serves not only to divert the sound wave generated by the sound generating portion 10 but also to guide the radiation direction of the diverted sound wave.
It should be noted that, since the holding arm 221 of the holding portion 22 is not located at the open end 32 of the radiation passage 30, the holding portion 22 does not adversely affect the sound quality of the speaker.
Meanwhile, after the external sound wave radiated to the speaker is radiated to the second turning surface 212 of the turning part 21, the radiation direction can be changed due to the blocking by the second turning surface 212 of the turning part 21, and in this way, the external sound wave can be further prevented from interfering with the sound quality of the speaker, thereby being beneficial to further ensuring the sound effect purity of the sound of the speaker.
Fig. 9 to 11C show a modified embodiment of the speaker, unlike the speaker shown in fig. 1 to 5C, in the modified embodiment of the speaker shown in fig. 9 to 11C, the holder 22 includes a holder 222 and a mounting plate 223, wherein a lower end portion of the holder 222 is mounted to a frame of the sound emitting portion 10, or a lower end portion of the holder 222 is integrally extended to a frame of the sound emitting portion 10, and wherein the mounting plate 223 is mounted to a higher end portion of the holder 222, or the mounting plate 223 is integrally formed to a higher end portion of the holder 222.

It will be appreciated by those skilled in the art that in this particular example of the speaker shown in fig. 9-11C, the diverter 21 may be devoid of the second diverter surface 212.
Preferably, the steering part 21 has a guiding surface 217, wherein the guiding surface 217 integrally extends from the first steering surface 211 to the first steering surface 211, and the guiding surface 217 surrounds the first steering surface 211 for guiding the radiation direction of the sound wave which is steered by the first steering surface 211 of the steering part 21. It should be noted that the extending direction of the first turning surface 211 of the turning portion 21 may or may not be identical to the extending direction of the guiding surface 217, which is selected according to the requirement of the speaker.
Referring to fig. 10, in this specific example of the speaker, the extending direction of the first diverting surface 211 of the diverting portion 21 coincides with the extending direction of the diaphragm 11 of the sound generating portion 10, the extending direction of the guide surface 217 of the diverting portion 21 coincides with the extending direction of the guide surface 231 of the guide portion 23, and the extending direction of the first diverting surface 211 of the diverting portion is opposite to the extending direction of the guide surface 217.
With continued reference to fig. 9 and 10, the acoustic wave steering structure 20 further includes a sound absorbing portion 24, where the sound absorbing portion 24 is disposed on the mounting plate 223, and the sound absorbing portion 24 is not disposed in the steering space 50, that is, the sound absorbing portion 24 and the steering portion 21 are respectively disposed on two sides of the mounting plate 223, and when an external acoustic wave is radiated toward the speaker, the sound absorbing portion 24 can absorb the external acoustic wave radiated to the speaker, so as to avoid the external acoustic wave interfering with the acoustic wave of the speaker and adversely affecting the sound effect of the speaker. For example, the sound absorbing portion 24 may be implemented as, but not limited to, sound absorbing cotton.
Fig. 11A to 11C show a state when the speaker is applied, in which the sound generating part 10 of the speaker can be connected to a sound source by a wired or wireless connection, in which the sound source can supply an audio signal, the sound generating part 10 can generate a sound wave by means of the diaphragm 11 driving air in response to an input of the audio signal, after the sound wave is radiated to the first diverting surface 211 of the diverting part 21, it can be diverted by being blocked by the first diverting surface 211 of the diverting part 21, in which the diverted sound wave can enter the radiation channel 30 from the inner side end 31 of the radiation channel 30, and radiate from the open end 32 of the radiation channel 30 to the outside of the speaker, in which the diaphragm 11 of the sound generating part 10, the first diverting surface 211 of the diverting part 21, the guide surface 217, and the guide surface 231 of the guide part 23 can guide a radiation direction of the diverted sound wave. That is, the first diverting surface 211 of the diverting portion 21 serves not only to divert the sound wave generated by the sound generating portion 10 but also to guide the radiation direction of the diverted sound wave.
Meanwhile, external sound waves radiated to the speaker can be absorbed by the sound absorbing part 24 when radiated to the sound absorbing part 24, so as to avoid interference of the external sound waves with the sound waves of the speaker, thereby being beneficial to further ensuring the sound effect purity of the sound of the speaker.
