To address this issue, the present application provides an electroacoustic device 100 (shown in fig. 1) and an electronic device 1000 (shown in fig. 6).

Referring to fig. 1 to 3, an electroacoustic device 100 according to an embodiment of the present disclosure includes a frame 10, a magnet 20, a support 30, a diaphragm 40, and a voice coil 50. A magnet 20 is provided in the tub 10 for generating a magnetic field. The voice coil 50 is fixedly connected with the diaphragm 40, and the voice coil 50 is powered on and vibrates under the action of the magnetic field of the magnet 20 to drive the diaphragm 40 to vibrate and sound. The support 30 comprises a first side 31 and a second side 33 which are opposite to each other, the support 30 is sleeved on the basin frame 10, the diaphragm 40 is combined with the second side 33 of the support 30 to form a first cavity 10a, the first side 31 of the support 30 is provided with a sound emitting protrusion 35, the sound emitting protrusion 35 is located outside the first cavity 10a, the sound emitting protrusion 35 comprises a side surface 351 which is deviated from the basin frame 10, a sound emitting channel 353 which is communicated with the first cavity 10a and penetrates through the side surface 351 is arranged, and the side surface 351 is inclined relative to the surface 310 of the first side 31 of the support 30.

The utility model provides an electroacoustic device 100, be provided with sound-producing protrusion 35 through the first side 31 at support 30, sound-producing protrusion 35 is located the outside of first cavity 10a, sound-producing protrusion 35 is including deviating from the side 351 of basin frame 10, and side 351 is compared in the surface 310 slope of the first side 31 of support 30, make under the condition that the overall structure size at electroacoustic device 100 keeps unchangeable, still can guarantee the regional characteristic area of sufficient sound-producing passageway 353 when magnetic circuit expands, ensure the fixed area of sound-producing passageway 353 outer damping net 355, avoid expanding outward because of magnetic circuit 50's upgrading and lead to the not enough problem of damping net 355 fixed area, make electroacoustic device 100 need not to reserve great marginal width with fixed damping net 355, guarantee that the inner space of electroacoustic device 100 can not take place the reduction, promote electroacoustic device 100's vocal effect.

In some embodiments, when the electroacoustic device 100 operates, alternating current is applied to the voice coil 50, the energized voice coil 50 vibrates under the driving of the magnetic circuit system, the voice coil 50 is fixedly connected to the diaphragm 40, and when the voice coil 50 vibrates, the diaphragm 40 is driven to vibrate together, wherein sound generated by the vibration of the diaphragm 40 is transmitted through the sound transmission channel 353, so as to achieve the conversion between the electric energy and the sound energy. In order to ensure the sound production effect of the electroacoustic device 100, the damping net 355 needs to be arranged outside the sound outlet channel 353 to adjust the sound quality, and a limit requirement is provided between the width of the damping net 355 and the width of the sound outlet channel 353, that is, if the width of the sound outlet channel 353 is small, the problem that the damping net 355 is difficult to fix is caused, and the sound production effect of the electroacoustic device 100 is further influenced. Under the condition that the overall structure size of the electroacoustic device 100 is kept unchanged, the fixing area of the damping net 355 is reduced due to the upgrade and extension of the magnetic circuit system, so that the damping net 355 is difficult to fix, and if the size is not adjusted, the problem of the loss of the original acoustic performance of the electroacoustic device 100 is caused.

In order to solve the problem of acoustic performance loss, some electroacoustic devices are additionally provided with a special-shaped structure outside the external structure size of the electroacoustic device, so that the circumferential side wall of the electroacoustic device is provided with a radially extending sound outlet channel, and further the reduction of the fixed area of a damping net caused by the upgrade and the expansion of a magnetic circuit system is avoided.

Compare with two kinds of preceding electroacoustic devices, the electroacoustic device 100 of this application can still guarantee sufficient regional characteristic area of play sound passageway 353 when magnetic circuit expands under the unchangeable circumstances of overall structure size, ensures the fixed area of the outside damping net 355 of play sound passageway 353, avoids causing the difficult problem of electroacoustic device 100 shaping because of addding the special-shaped structure, promotes the space utilization of electroacoustic device 100. In addition, the electroacoustic device 100 of this application is through setting up out the sound protruding 35 on the first side 31 at support 30, sound channel 353 has been seted up in sound protruding 35's inside, make under the external dimension of the structure of guaranteeing electroacoustic device 100 keeps unchangeable circumstances, sound channel 353's the orientation of seting up can be adjusted according to the particular case of installing in electronic equipment 1000, avoid causing the single problem of sound channel 353 orientation because of sound channel 353 installs in the lateral wall of basin frame 10, improve electroacoustic device 100's commonality, and production cost is reduced.

The electroacoustic device 100 is further described below with reference to the drawings.

Referring to fig. 1, in some embodiments, the electroacoustic device 100 further includes a cover 60, and the cover 60 is combined with the diaphragm 40 to form a second cavity 10b for preventing the diaphragm 40 from being damaged by external impact and affecting the sound generating performance of the electroacoustic device 100. In some embodiments, the cover 60 is provided with a through hole, which is beneficial to transmitting the sound generated by the vibration of the diaphragm 40, and improves the sound production effect of the electroacoustic device 100.

Referring again to fig. 2, in some embodiments, the sound exit passage 353 has a straight cylindrical shape, and a central axis OO1 of the sound exit passage 353 is inclined relative to the surface 310 of the first side 31 of the support 30. Wherein, the sound that vibrating diaphragm 40 produced can not turn back the vibrating diaphragm 40 along original direction after the inner wall reflection of lid 60, but most can propagate along a vocal passageway 353 direction for most sound that vibrating diaphragm 40 produced can directly spread from a vocal passageway 353, avoids producing the standing wave and interferes and lead to sound to offset each other, thereby can improve the sound radiation efficiency of electroacoustic device 100, promotes electroacoustic device 100's vocal effect. It should be noted that, in some embodiments, the cross-sectional shape of the sound outlet channel 353 may be a circle, a square, a diamond, a triangle, or the like, which is not limited herein.

It should be noted that, in some embodiments, a certain included angle β is formed between the central axis OO1 of the sound emitting channel 353 disposed in the sound emitting protrusion 35 of the first side 31 and the surface 310 where the first side 31 is located, and when the included angle β formed between the central axis OO1 of the sound emitting channel 353 and the surface 310 where the first side 31 is located is within a predetermined angle range, on the premise that the external structural size of the electroacoustic device 100 is not increased, a sufficient characteristic area of the region of the sound emitting channel 353 can be still ensured when the magnetic circuit system is expanded, and a fixed area of the damping mesh 355 outside the sound emitting channel 353 is ensured. In addition, when the electroacoustic device 100 is installed in the electronic apparatus 1000, the position of the sound emitting channel 353 may interfere with other components in the electronic apparatus 1000, which affects the assembly of the electroacoustic device 100, at this time, the electroacoustic device 100 may change the support 30 having different included angles β, and further change the direction of the sound emitting channel 353, thereby avoiding the problem that the assembly cannot be performed due to the interference between the position of the sound emitting channel 353 and other components in the electronic apparatus 1000, improving the applicability of the electroacoustic device 100, and adjusting the direction of the sound emitting channel 353 by replacing the support 30, which can simplify the processing technology of the electroacoustic device 100 and reduce the production cost. In some embodiments, the included angle between the central axis OO1 of the sound outlet channel 353 and the surface 310 of the first side 31 is any angle greater than 0 ° and less than 90 °, for example, the included angle between the central axis OO1 of the sound outlet channel 353 and the surface 310 of the first side 31 is 5 °, 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, 80 °, or 85 °, and the like, which is not limited herein. It should be noted that, when an included angle between the central axis OO1 of the sound emitting channel 353 and the surface 310 where the first side 31 is located is 0 °, the sound emitting channel 353 is difficult to form, the difficulty of fixing the damping net 355 is high, the direction of the sound emitting channel 353 is single, the shape and the path of the sound emitting channel 353 are not easy to change, and the processing cost is high. When the included angle between the central axis of the sound emitting channel 353 and the plane of the first side 31 is 90 °, a larger area needs to be reserved for fixing the damping net 355 for the sound emitting channel 353, and under the condition that the overall structure size of the electroacoustic device 100 is not changed, the upgrade and expansion of the magnetic circuit system 50 are limited, and the sound emitting effect of the electroacoustic device 100 is affected.

Referring to fig. 4 and 5, in some embodiments, the sound outlet channel 353 includes a plurality of sound outlet holes, the sound outlet holes are connected in a bent manner, and the sound outlet channel 353 includes an inlet 3531 communicated with the first cavity 10a and an outlet 3533 located on the side surface 351. It should be noted that, in some embodiments, the bending portion of the multiple sound outlet holes may be connected in a straight manner or in a smooth manner, and compared with the connection in a straight manner between the multiple sound outlet holes, the smooth connection may effectively reduce the obstruction of the sound outlet channel 353 to the sound generated by the vibration of the diaphragm 40, so as to improve the smoothness of the sound when propagating, and further effectively improve the sound performance of the electroacoustic device 100.

Specifically, referring to fig. 4, in one embodiment, the center of the inlet 3531 is located on a first plane 3535 perpendicular to the first side 31 of the support 30, and the center of the outlet 3533 is located on a second plane 3537 perpendicular to the first side 31 of the support 30, wherein the first plane 3535 coincides with the second plane 3537, and the center of the inlet 3531, the center of the outlet 3533, and the central axis of each sound outlet are all in the same plane (the first plane 3535 or the second plane 3537). The utility model provides an electroacoustic device 100 is connected through the buckling of multistage sound outlet hole, and then makes the export 3533 position of sound outlet channel 353 adjust at wider range, improves electroacoustic device 100's suitability. Referring to fig. 2 and 4, in some embodiments, an included angle γ formed between a central axis of the sound outlet hole close to the outlet 3533 and the surface 310 where the first side 31 is located is larger than an included angle β formed between a central axis OO1 of the straight-cylindrical sound outlet channel 353 shown in fig. 2 and the surface 310 where the first side 31 is located, and an area of the sound outlet channel 353 corresponding to the included angle γ is larger than an area of the sound outlet hole 353 corresponding to the included angle β. Therefore, the larger the angle γ formed by the central axis of the sound outlet hole near the outlet 3533 and the surface 310 on which the first side 31 is located, the larger the area of the corresponding sound outlet channel 353. In a predetermined angle range, by increasing the angle of the included angle γ, under the condition that the external structural size of the electroacoustic device 100 is not changed, the area of the sound hole 353 is increased, that is, the fixed area of the damping net 355 is further increased, and the sound generated by the vibration of the diaphragm 40 and the heat generated by the voice coil 50 can be rapidly discharged in the larger sound outlet channel 353 area, so that the sound is prevented from being irregularly propagated in the frame 10 to generate noise, and the sound production performance of the electroacoustic device 100 is prevented from being affected.

Referring to fig. 5, in another embodiment, the inlet 3531 is centered within a first plane 3535 perpendicular to the surface 310 of the support frame 30, and the outlet 3533 is centered within a second plane 3537 perpendicular to the surface 310 of the support frame 30, the first plane 3535 being different from the second plane 3537. It should be noted that the first plane 3535 and the second plane 3537 may intersect or be parallel. That is, the inlet 3531 and the outlet 3533 of the sound outlet channel 353 are not in the same plane (from the perspective of the top view of the perspective view shown in fig. 5, the center of the inlet 3531 and the center of the outlet 3533 are located in two vertical planes which are perpendicular to the surface 310 and both pass through the center of the basin stand 10), so that the position where the electroacoustic device 100 is installed in the electronic device 1000 has certain adjustability, the universality of the electroacoustic device 100 is improved, and the production cost is reduced.

When the inlet 3531 and the outlet 3533 of the sound exit channel 353 are located on different planes, in some embodiments, the sound exit channel 353 can be a straight cylinder. In other embodiments, the sound outlet channel 353 may also include a sound outlet hole with multiple bends, where the bend may be a straight bend or a curved bend, and the bend is not limited herein.

Referring to fig. 3, in some embodiments, the side 351 of the sound-emitting protrusion 35 is provided with a damping net 355, and the damping net 355 covers the outlet 3533 of the sound-emitting channel 353. Although the sound outlet channel 353 with a large aperture is convenient for sound transmission, the acoustic resistance of the electroacoustic device 100 is reduced, and the sound effect of the electroacoustic device 100 is influenced, so that the damping net 355 covers the sound outlet channel 353 to increase the acoustic resistance and improve the sound production effect of the electroacoustic device 100. Meanwhile, the damping net 355 can also prevent impurities such as external dust from entering the inside of the electroacoustic device 100, and prevent the impurities such as external dust from entering the magnetic gap to cause the internal elements of the electroacoustic device 100 to be damaged and influence the sound production effect of the electroacoustic device 100. In some embodiments, the damping mesh 355 may be a mesh made of a non-metallic material, which has a relatively large acoustic resistance to enhance the sound effect of the electroacoustic device 100, and which can be better fixed to the side 351 of the sound-emitting protrusion 35.

In some embodiments, the damping net 355 may be disposed on the side 351 by bonding, welding or injection molding, and the bonding or welding connection manner is adopted, so that the processing process is simpler and the production efficiency is improved.

In some embodiments, the sound emitting protrusion 35 may be one or more. When the sound-emitting protrusions 35 are plural, the plural sound-emitting protrusions 35 are uniformly distributed around the center of the diaphragm 40. That is, the first side 31 of the support 30 can be provided with a plurality of sound emitting channels 353, the plurality of sound emitting channels 353 can be uniformly arranged in the circumferential direction of the support 30, and the design can rapidly discharge the air flow and the heat generated in the power-on work of the voice coil 50, so that the noise generated by the irregular flow of the air flow in the basin stand 10 is avoided, and the sound production performance of the electroacoustic device 100 is influenced.
