Sound emitting devices, i.e. devices that can emit sound. Specifically, a loudspeaker is arranged in the sound generating device, and sound generation of the sound generating device is realized through vibration sound generation of the loudspeaker. However, sound emitting devices in the current industry are limited by space, such as: the instrument panel of a vehicle has a limited space in the front-rear direction, so that it is usually provided with only one horn. At this time, the setting of only one loudspeaker makes this sound generating mechanism only suitable for the frequency type that plays this loudspeaker corresponds, and then makes the frequency type that this sound generating mechanism can be suitable for the sound of broadcasting comparatively singlely, and then leads to influencing sound generating mechanism's acoustic effect.

Based on the above consideration, the application provides a novel sound generating device in order to solve the problem that the sound generating device in the current industry is poor in acoustic effect caused by the fact that only one loudspeaker can be arranged. This sound generating mechanism innovatively sets up first loudspeaker in the mounting groove of installation carrier, sets up the second loudspeaker in the outside of mounting groove simultaneously, and covers the part of second loudspeaker in the upper and lower direction with the mounting groove to carry out compact stack setting in limited space between installation carrier, first loudspeaker and the second loudspeaker three, and carry out diversified sound production and improve sound generating mechanism's acoustic effect through these two at least horns.

In addition, it is also described that the sound generating device according to the present application may be applied to a vehicle or other devices as described below, and of course, the sound generating device may be used independently, for example: the sound box is used as a household sound box or an outdoor sound box.

Next, the structure of the sound generating apparatus according to the present application will be explained and illustrated with reference to fig. 1 to 7, and in an embodiment of the present application, the sound generating apparatus 100 according to the present application includes a mounting carrier 10, a first speaker 20, and a second speaker 30. The mounting carrier 10 is provided with a mounting groove 111 defining the sound generating apparatus 100 to have an up-down direction (up-down direction defined in a state in which the sound generating apparatus 100 is placed in normal use), the notch of the mounting groove 111 being provided upward; the first horn 20 is provided in the mounting groove 111; the second horn 30 is provided on the mount carrier 10 and is located outside the mount groove 111, and the projection of the mount groove 111 covers the projected portion of the second horn 30 on a projection plane perpendicular to the up-down direction.

The mounting carrier 10 may be used to provide a mounting location for mounting the load bearing first horn 20 and the second horn 30. The mounting carrier 10 may be a shell structure, a plate structure, or a frame structure, and the application does not limit the structural form of the mounting carrier 10, so as to ensure that the first speaker 20 and the second speaker 30 can be mounted and carried. Similarly, the shape of the mounting carrier 10 is not limited, and may be any shape such as a circle, a square, or a rectangle. Further, when the sound generating apparatus 100 is applied to a device such as a vehicle, the mount carrier 10 may be a partial structure of a vehicle body of the vehicle, for example: the instrument desk may be formed directly, or may be formed independently of another object of the vehicle body.

The first horn 20 may be mounted in the mounting groove 111 for compact arrangement on the mounting carrier 10. The first horn 20 may be a tweeter as described below, or may be a midrange horn or a woofer, which is not limited in the present application. In addition, the first horn 20 may be rotatably provided in the mounting groove 111 as described below, and have a first state and a second state. In the first state, the first horn 20 is accommodated in the installation groove 111. At this time, it is defined that the first horn 20 has a first sound outlet surface 21, and the first sound outlet surface 21 may be disposed vertically upward or vertically downward. In the second state, the first speaker 20 may be rotatably extended from the notch of the mounting groove 111, so that the first sound emitting surface 21 of the first speaker 20 may be disposed obliquely upward. Of course, the first speaker 20 may be fixedly installed in the installation groove 111, and have a first state in which the first sound emitting surface 21 is vertically upward, or a second state in which the first sound emitting surface 21 is obliquely upward.

The second horn 30 may be installed outside the installation groove 111 and covered by a projection of the installation groove 111 so as to be compactly stacked with the installation carrier 10 and the first horn 20, thereby greatly reducing the occupation of the installation space required for the sound generating apparatus 100. Particularly when applied to a vehicle, where the space of the instrument panel of the vehicle in the front-rear direction is limited, the use of this stacked arrangement is more convenient for realizing the mounting arrangement of the sound generating device 100 of the present application having at least two horns on the instrument panel. In order to facilitate the projection of the mounting groove 111 in the up-down direction to cover the second horn 30, the cross section of the mounting groove 111 may be increased in the down-up direction. For example: the mounting groove 111 may have a hemispherical shape, an inverted truncated cone shape, a combination of a hemispherical shape and an inverted truncated cone shape, or the like. The second horn 30 may be a midrange horn as described below, or may be a tweeter or a woofer, and the present application is not limited thereto.

Meanwhile, the second horn 30 is disposed outside the mounting groove 111 and is covered by the projection of the mounting groove 111 in the up-down direction, so that the second horn 30 can be compactly arranged with the mounting carrier 10 as well. That is, the compact stacking arrangement among the mounting carrier 10, the first horn 20 and the second horn 30 is realized, and at least two horns can be disposed in a limited space, so that more diversified sound production can be performed through the at least two horns to improve the acoustic effect of the sound production device 100.

Particularly, when the first speaker 20 is a tweeter as described below, the possibility that the high-frequency sound with strong directivity emitted by the tweeter is blocked and reflected by other objects (such as a windshield on the front side of an instrument panel of a vehicle) can be reduced, so that the playing effect of the sound generating apparatus 100 on the high-frequency sound is improved, and the user experience is improved. In addition, the first loudspeaker 20 is rotatable, so that the first loudspeaker 20 has a dynamic appearance in the use process, and further the use experience of a user is improved.

Referring to fig. 1, in a first state, the first sound emitting surface 21 of the first speaker 20 is disposed opposite to the bottom of the mounting groove 111. Therefore, even in the first state, the first sound emitting surface 21 can better correspond to the notch of the mounting groove 111, so that the first loudspeaker 20 in the first state can be better used for emitting sound.

Referring to fig. 4, in an embodiment of the present application, an included angle α formed by an axis of the first horn 20 and an axis of the first horn 20 in the second state is defined as: alpha is more than or equal to 60 degrees and less than 90 degrees.

In the present embodiment, the angle α formed by the axis of the first horn 20 and the axis of the second horn 30 in the second state is set to 60 ° to 90 °, so that the first horn 20 is neither excessively inclined nor excessively inclined when in the second state. That is, the first speaker 20 may have a suitable inclination, and may better sound toward the user, so as to improve the acoustic effect of the first speaker 20 and enhance the user's feeling of sound. The angle α formed by the axis of the first horn 20 and the axis of the second horn 30 in the second state may be 560 °, 65 °,70 °, 75 °,80 °, 85 ° or 89 °, or may be any value of the above intervals.

The above-mentioned limitation of the angle relationship between the first horn 20 and the second horn 30 in the second state is used to obtain a suitable degree of inclination of the first horn 20, but in an embodiment of the application, the limitation of the mounting posture of the first horn 20 may be unilaterally used to obtain a suitable degree of inclination of the first horn 20. That is, an included angle β formed between the axis of the first horn 20 in the second state and the up-down direction is defined, and the relationship is satisfied: beta is more than or equal to 70 degrees and less than 90 degrees. At this time, the first speaker 20 may not be excessively inclined or excessively inclined when being in the second state, so that the first speaker 20 may better sound toward the user. The angle β formed between the axis of the first horn 20 in the second state and the vertical direction may be 70 °, 75 °, 80 °, 85 ° or 89 °, or any value of the above intervals.

Referring to fig. 4, in an embodiment of the present application, an included angle between an axis of the second speaker 30 and an up-down direction is defined as P, which satisfies the following relationship: p is more than or equal to 0 DEG and less than or equal to 5 deg.

In this embodiment, when the included angle P between the axis of the second horn 30 and the up-down direction is 0 °, that is, the axis of the second horn 30 may be disposed vertically. At this time, the second horn 30 is mounted irregularly, thereby contributing to improvement of convenience in mounting arrangement thereof. Of course, when the included angle P between the axis of the second horn 30 and the vertical direction is 0 ° < p+.ltoreq.5°, that is, the axis of the second horn 30 may be disposed obliquely. At this time, the second horn 30 is provided to be inclined, and the compactness of the stack between the second horn 30 and the mount carrier 10 and the first horn 20 in the first direction can be improved. In addition, when the second sound emitting surface 35 of the second speaker 30 is inclined toward the rear side, that is, toward the side away from the first speaker 20, the second speaker 30 can be more conveniently used for emitting sound toward the side where the user is located. Of course, the second sound emitting surface 35 of the second horn 30 may be inclined toward the front side, that is, toward the side close to the first horn 20, and the direction of inclination of the second horn 30 in the first direction is not limited in the present application. At this time, the angle P between the axis of the second horn 30 and the vertical direction may be 1 °,2 °,3 °,4 °, or 5 °, or any of the above sections.

In one embodiment of the present application, the first horn 20 is a tweeter and the second horn 30 is a midrange.

In this embodiment, the high-frequency band sound and the mid-frequency band sound are played by the tweeter and the midrange loudspeaker in a targeted manner, so that the respective playing effects of the high-frequency band sound and the mid-frequency band sound can be enhanced. That is, the sound generating apparatus 100 can play sound with a relatively rich frequency, and can play high-frequency sound and medium-frequency sound at the same time, thereby being beneficial to improving the acoustic effect of the sound generating apparatus 100. And more importantly, the second sound emitting surface 35 of the midrange speaker in the sound emitting device 100 is also upward, so that the midrange speaker can radiate sound better towards the periphery, thereby improving the playing effect of the sound emitting device 100 on the middle frequency band sound. The first sound emitting surface 21 of the tweeter in the second state as described above may be inclined upwards, and the tweeter axis in the first state is intersected with the axis of the midrange horn, so that the tweeter with relatively strong directivity can better emit sound towards the user, thereby reducing the possibility that the high-frequency sound with strong directivity emitted by the tweeter is blocked and reflected by other objects, and improving the playing effect of the sound emitting device 100 on the high-frequency sound. Therefore, the structure of the sound generating apparatus 100 is set on the basis of enriching the frequency types of the applicable sound, and the playing effects of the middle-frequency band sound and the high-frequency band sound are greatly improved, so that the acoustic effect of the sound generating apparatus 100 is further improved.

Referring to fig. 7 in combination with fig. 11 to 13, in an embodiment of the application, when the first speaker 20 is rotatably disposed, in order to improve smoothness of rotation of the first speaker 20 and compactness of stacking and distributing the first speaker 20 and the mounting carrier 10, the first speaker 20 may further include a rear surface 22, and the rear surface 22 is connected to the first sound emitting surface 21 and is disposed in a convex spherical surface. The groove wall of the mounting groove 111 includes a spherical wall surface 113, and the spherical centers of the spherical wall surface 113 and the rear surface 22 coincide. Further, since the first sound emitting surface 21 of the first speaker 20 is inclined when the first speaker 20 is in the second state, the bottom portion of the first sound emitting surface 21 is still located in the mounting groove 111. Therefore, in order to avoid that the wall of the installation groove 111 blocks the sound emission of the bottom portion of the first sound emission surface 21 of the first speaker 20 located in the second state, the wall of the installation groove 111 may further include an inclined wall surface 115, the inclined wall surface 115 is connected to the spherical wall surface 113, and a notch of the installation groove 111 is formed by enclosing an end of the spherical wall surface 113 away from the spherical wall surface 113, and the inclined wall surface 115 is arranged in a flaring shape in a bottom-up direction. Wherein, when the mounting groove 111 includes the cover body 112 and the surrounding plate 114 as described above, the spherical wall surface 113 may be formed from the inner side surface of the cover body 112, and the inclined wall surface 115 may be formed from the side surface of the surrounding plate 114. Further, in order to reduce the overall volume of the mounting hood 11 for facilitating the subsequent compact stacking arrangement, the shape of the outer wall surface of the hood body 112 may be set to be the same as the shape of the inner spherical wall surface 113, and the shape of the outer wall surface of the surrounding plate 114 may be set to be the same as the shape of the inner inclined wall surface 115. In addition, in the first state, the end of the first speaker 20 with the first sound emitting surface 21 may be protruded from the notch of the mounting groove 111, so as to further reduce the blocking effect of the groove wall of the mounting groove 111 on the sound emission of the first speaker 20.

Referring to fig. 11 to 13 in combination, in an embodiment of the present application, the sound generating apparatus 100 further includes a driving mechanism 90, where the driving mechanism 90 is disposed on the mounting carrier 10 and connected to the first speaker 20 to drive the first speaker 20 to rotate.

The driving member 91 may be used to provide power, and the transmission assembly 93 may be used to transmit the motion of the driving member 91 to the first horn 20, so as to indirectly drive the first horn 20 by the driving member 91. Wherein the driving member 91 may be a motor. For example: the motor may be a stepping motor, a servo motor, or the like, and the application is not limited thereto. Of course, the driving member 91 may be a rotary cylinder. That is, the driving member 91 is only required to be used for providing the rotational driving force. The first drive wheel 931 and the second drive wheel 932 of the drive assembly 93 may be roller structures, which may be used with the conveyor belt 933. Of course, the first driving wheel 931 and the second driving wheel 932 may be gear structures, and may be directly engaged with each other or further used in combination with the conveyor belt 933. Alternatively, the first and second drive wheels 931 and 932 may be sprocket arrangements, which are used with a conveyor chain. Accordingly, the specific types of the first and second driving wheels 931 and 932 in the driving assembly 93 are not limited, and it is sufficient that the first driving wheel 931 can transmit the rotation of the driving member 91 to the second driving wheel 932.

In this embodiment, the driving mechanism 90 is configured to include the driving member 91 and the transmission assembly 93, so that on one hand, the transmission assembly 93 can be used to make the first horn 20 obtain a suitable transmission ratio, so as to avoid the influence on the stability of the sound generating apparatus 100 caused by the over-fast rotation of the first horn 20. On the other hand, the driving member 91 can be mounted around the rotation circumference of the first horn 20, so that the requirement on the mounting position of the driving member 91 is reduced, the convenience of mounting the driving member 91 is improved, and a basic condition is provided for realizing compact mounting of the driving mechanism 90. In addition, the axis of the connecting shaft 23 provided on the second horn 30 may pass through the center of sphere of the rear surface 22 of the second horn 30. In addition, in order to avoid interference between the first horn 20 and the driving mechanism 90 during installation, the mounting frame 15 of the mounting carrier 10 may be further provided with a seating cavity 152 isolated from the receiving cavity 151, and the driving mechanism 90 may be provided in the seating cavity 152, and the connection shaft 23 may extend into the seating cavity 152 through the mounting cap 11 and the mounting frame 15. And for convenience of installation and maintenance, the installation cavity 152 may have an opening, and a detachable cover plate 153 may be covered at the opening.

Referring to fig. 12, in an embodiment of the present application, the first driving wheel 931 and the second driving wheel 932 are gears.

Referring to fig. 12, in an embodiment of the application, the transmission assembly 93 further includes a belt 933, and two ends of the belt 933 are sleeved on the first transmission wheel 931 and the second transmission wheel 932.

In this embodiment, the first driving wheel 931 can rotate the conveyor belt 933 after being driven by the driving member 91 to rotate. At the same time, the rotating conveyor belt 933 drives the second drive wheel 932. At this time, there is no direct engagement between the first driving wheel 931 and the second driving wheel 932, so that the setting positions of the driving member 91 and the first driving wheel 931 are not affected by the engagement between the first driving wheel 931 and the second driving wheel 932, and further, the distance between the driving member 91 and the first driving wheel 931 and the second driving wheel 932 can be set adaptively according to actual needs. That is, after the distance between the driving member 91 and the first and second driving wheels 931 and 932 is designed, a conveyor belt 933 of a corresponding length is used, thereby facilitating the convenience of the arrangement of the driving member 91 and the first driving wheel 931. Further, in the case where the first driving wheel 931 and the second driving wheel 932 are both gears, in order to further improve the stability of the driving, the conveyor belt 933 may be provided with meshing teeth that mesh with the first driving wheel 931 and the second driving wheel 932.

In this embodiment, the transmission assembly 93 further includes a mounting shaft 934, a worm wheel 935, and a worm 936, so that the driving member 91 and the first driving wheel 931 do not need to be sequentially distributed in the axial direction of the first driving wheel 931, but the axis of the driving member 91 and the axis of the first driving wheel 931 may be disposed in a staggered manner. This further increases the compactness of the distribution between the driver 91 and the transmission assembly 93, so as to reduce the overall volume of the sound generating apparatus 100 and to increase the convenience of subsequent placement thereof. Of course, in other embodiments, the first driving wheel 931 may be disposed directly on the driving member 91 when the mounting shaft 934, the worm wheel 935 and the worm 936 are not included in the driving assembly 93.
