Description
Technical Field
[0001] The utility model relates to the technical field of alarms, in particular to a loudspeaker and a vehicle. Background Art
[0002] Due to its driving mode, a new energy vehicle makes almost no sound when the vehicle speed is low, unable to alert surrounding pedestrians or vehicles, and there are some potential dangers.

[0037] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0039] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.
[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, when describing pipelines or channels, the terms "connected" and "connection" used in this application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.
[0041] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.
[0042] As used herein, "about", "substantially", or "approximate" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system).
[0043] Due to its driving mode, new energy vehicles make almost no sound when driving at low speeds, which poses a certain safety hazard to surrounding pedestrians or other vehicles. To solve this problem, a device that can simulate engine sounds is needed to alert surrounding pedestrians and vehicles of its approach and ensure safety.
[0044] In the related art, the device for simulating engine sounds is composed of a speaker unit and a housing, and is vertically installed on the front bumper of a new energy vehicle. The Acoustic Vehicle Alerting System (AVAS) can simulate engine sounds and issue warnings to the surrounding area, effectively alerting surrounding pedestrians and vehicles.
[0045] According to the corresponding regulations, when the vehicle is moving forward, the simulated engine sound needs to meet the following requirements at a distance of 2 m from the vehicle: the sound should reach 52 dB at a speed of 10 km / h, 58 dB at a speed of 20 km / h, and 49 dB at a speed of 6 km / h when reversing. Since the speaker diaphragm faces forward and the rear cover faces the passenger compartment, some of the sound will directly pass through the rear cover and reach the interior of the vehicle, generating noise. According to tests, with the AVAS speaker meeting the regulatory requirements, the pink noise inside the vehicle reached 50 dB, which had an adverse impact on the in-vehicle experience of the passengers.
[0046] To solve the above problems, the present application proposes a speaker.
[0047] As Figure 1 and Figure 2 shown, Figure 1 is a structural diagram of a speaker provided by an embodiment of the present application, Figure 2 is Figure 1 a schematic cross-sectional structure diagram of the structure shown along the A-A direction. The speaker 100 provided by the present application includes a box body 1, a sound generating unit 2, and a sound insulation component 3.
[0048] Among them, an installation cavity 11 is provided inside the box body 1. The installation cavity 11 is used to accommodate the devices arranged therein, and the box body 1 provides protection for the devices installed therein.
[0049] An sound outlet 12 is further provided on the box body 1, and the sound outlet 12 is communicated with the installation cavity 11. The sound generating unit 2 is arranged in the installation cavity 11, and the sound generating unit 2 is arranged opposite to the sound outlet 12. The sound emitted by the sound generating unit 2 is transmitted to the outside of the box body 1 through the sound outlet 12.
[0050] This application does not specifically limit the shape of the box body 1, and the shape of the box body 1 can be determined according to the space where the box body 1 is installed.
[0051] In a possible implementation manner, the box body 1 includes a housing 13 and a rear cover 14. The housing 13 and the rear cover 14 are detachably connected, and the installation cavity 11 is located between the housing 13 and the rear cover 14.
[0052] Exemplarily, the housing 13 and the rear cover 14 can be one of bolt connection, snap connection, plug connection, buckle connection, magnetic connection, or adhesive connection. This application does not limit this.
[0053] Maintenance personnel can disassemble and assemble or repair the devices arranged in the installation cavity 11 by disassembling the rear cover 14, which is convenient for operation.
[0054] In a possible implementation manner, the sound generating unit 2 can be one of a dynamic loudspeaker, a capacitor loudspeaker, an electromagnetic induction loudspeaker, an electric loudspeaker, an electrostatic field loudspeaker, and a magnetostrictive loudspeaker.
[0055] Exemplarily, the sound generating unit 2 includes a voice coil, a diaphragm, and a magnetic circuit system. Specifically, the magnetic circuit system includes a magnet and a U-shaped iron. The voice coil is connected to the diaphragm, and the voice coil cooperates with the magnetic circuit system to drive the diaphragm to vibrate. The diaphragm is located on the side of the magnetic circuit system close to the sound outlet. Thus, the sound emitted by the sound generating unit 2 can be transmitted through the sound outlet 12.
[0056] Exemplarily, the sound generating unit 2 further includes components such as a dust cap, a speaker frame, a terminal board, and a spider.
[0057] The diaphragm is located between the voice coil and the sound outlet 12, and a sound output channel is formed from the voice coil to the diaphragm. The sound output channel is communicated with the sound outlet 12. In this way, the sound emitted by the sound generating unit 2 can be emitted through the sound outlet 12.
[0058] Exemplarily, when the vehicle speed is lower than 30 km / h, the vehicle's on-board computer (ECU), that is, the electronic control unit system, sends a signal to the speaker 100, and the speaker works to emit a simulated engine sound to remind surrounding pedestrians and vehicles.
[0059] The sound insulation component 3 includes a plurality of sound insulation ribs 30, and the plurality of sound insulation ribs 30 are arranged in an array on the inner wall of the box body 1.
[0060] An array means a way of arranging and combining a plurality of sound insulation ribs 30 according to a certain rule.
[0061] Exemplarily, the plurality of sound insulation ribs 30 can be arranged in a straight line, or can also be arranged in a matrix array, or can also be arranged at equal intervals. Such a setting can increase the coverage range and uniformity of the acoustic effect.
[0062] Alternatively, the sound insulation ribs 30 can also be randomly arrayed to break the acoustic reflection and increase the diversity of the acoustic effect.
[0063] When an electric current passes through the sound generating unit 2, the sound generating unit 2 generates vibrations, and propagates the sound into the installation cavity 11. Since the sound generating unit 2 is opposite to and communicated with the sound outlet 12, the sound can directly emit from the sound outlet 12, simulating the sound characteristics of the engine sound to give a warning to the surroundings.
[0064] When the sound propagates in the installation cavity 11 and encounters the sound insulation ribs 30, a part of the sound will be blocked by the sound insulation ribs 30, so that the propagation of the sound in the box body 1 can be reduced. When another part of the sound encounters the sound insulation ribs 30, refraction occurs, causing the energy of the sound wave to be lost, so that the intensity of the sound wave gradually weakens during the propagation process, reducing the noise propagating towards the cockpit direction. The arrayed sound insulation ribs 30 can increase the loss of sound. In summary, when the loudspeaker 100 simulates the engine sound and gives a warning to the surroundings, the noise towards the cockpit direction can be reduced, thereby improving the experience of the passengers and drivers.
[0065] The embodiments of the present application will be introduced in detail below with reference to the drawings. Before introducing the embodiments of the present application in detail, the application scenarios of the embodiments of the present application will be introduced first.
[0066] The loudspeaker 100 is generally arranged at the front bumper of the vehicle, and the sound outlet 12 of the loudspeaker 100 faces the front of the vehicle, so that the engine sound simulated by the loudspeaker 100 can give a warning to the surroundings, effectively reminding the surrounding pedestrians and vehicles, and among the surrounding ranges, the effect in front of the vehicle is better.
[0067] The present application provides a vehicle, which includes a cockpit and the above-mentioned loudspeaker 100. The loudspeaker 100 is arranged outside the cockpit. Specifically, the loudspeaker 100 is arranged at the front bumper of the vehicle, and the sound outlet 12 of the loudspeaker 100 faces away from the cockpit and towards the front of the vehicle.
[0068] The cockpit is used for riding in and / or driving the vehicle.
[0069] Combined with Figure 3 and Figure 4As shown Figure 3 is Figure 2 a schematic structural diagram of the rear cover 14 in the loudspeaker shown Figure 4 is Figure 2 a schematic structural diagram of the housing 13 in the loudspeaker shown. In a possible implementation, the box body 1 includes a first wall surface 15 and a second wall surface 16 arranged opposite to each other, and the sound outlet 12 is arranged on the second wall surface 16, and the sound generating unit 2 (see Figure 2 ) is arranged between the first wall surface 15 and the second wall surface 16.
[0070] The plurality of sound insulation ribs 30 (see Figure 2 ) includes a plurality of first sound insulation ribs 31, and the plurality of first sound insulation ribs 31 are arranged in an array on the surface of the first wall surface 15 facing the second wall surface 16. When the box body 1 (see Figure 2 ) includes the housing 13 and the rear cover 14, the first wall surface 15 is located on the rear cover 14 and on the side of the rear cover 14 facing the housing 13, and the second wall surface 16 is located on the housing 13 and on the side of the housing 13 facing the cover body.
[0071] The first sound insulation rib 31 is arranged on the side of the rear cover 14 facing the front of the vehicle and between the sound generating unit 2 and the rear cover 14. Thus, during the process of the sound generated by the sound generating unit 2 spreading around, the first sound insulation rib 31 can reduce the spread of the sound towards the cockpit direction without affecting the spread in other directions, such as the spread towards the side of the vehicle.
[0072] At the same time, only arranging the first sound insulation rib 31 on the first wall surface 15 of the rear cover 14 can reduce the material usage of the first sound insulation rib 31, thereby saving materials.
[0073] In a possible implementation, the plurality of first sound insulation ribs 31 includes a plurality of first sound insulation rib groups 311 arranged along the first direction X, and the first sound insulation rib group 311 includes two rows of first sound insulation ribs 31 arranged along the first direction X, and each row of first sound insulation ribs 31 includes a plurality of first sound insulation ribs 31 arranged along the second direction Y. Among them, the first direction X and the second direction Y are perpendicular, and both the first direction X and the second direction Y are parallel to the first wall surface 15.
[0074] When the sound propagates to the first wall surface 15, it is weakened by the plurality of first sound insulation rib groups 311, the multiple rows of first sound insulation ribs 31, and the plurality of first sound insulation ribs 31, reducing the energy of the sound wave. At the same time, the plurality of first sound insulation ribs 31 can increase the refraction length during the sound propagation process, thereby increasing the loss of the sound wave energy during the refraction process, reducing the sound transmission, and thus reducing the noise spread towards the cockpit direction.
[0075] It should be noted that the sound generating unit 2 (see Figure 2)The propagated sound does not pass through each first sound insulation rib group 311, each row of first sound insulation ribs 31, and each first sound insulation rib 31. The refraction direction of the sound after contacting the first sound insulation rib 31 is determined according to the shape of the first sound insulation rib 31.
[0076] Exemplarily, two rows of first sound insulation ribs 31 are arranged in a staggered manner along the second direction Y. Thus, when the sound emitted by the sound generating unit 2 propagates out of the box body 1, the blocking of the sound by the first sound insulation ribs 31 can be increased, and the sound is prevented from directly propagating out of the box body 1 through the gaps between the first sound insulation ribs 31, thereby improving the sound insulation effect.
[0077] Exemplarily, taking the application scenario of the embodiment of the present application as an example, the first direction X can be the width direction of the vehicle, and the second direction Y is the height direction of the vehicle.
[0078] Exemplarily, taking the application scenario of the embodiment of the present application as an example, the first direction X can be the height direction of the vehicle, and the second direction Y is the width direction of the vehicle.
[0079] As Figure 5 shown, Figure 5 is Figure 3 an enlarged schematic view of part A in. In a possible implementation manner, the first sound insulation rib 31 includes a first plate portion 312 and a second plate portion 313.
[0080] Exemplarily, there is an included angle between the first plate portion 312 and the first wall surface 15. For example, the first plate portion 312 is perpendicular to the first wall surface 15.
[0081] The second plate portion 313 is located on one side of the first plate portion 312, and the first plate portion 312 and the second plate portion 313 intersect.
[0082] Exemplarily, the first plate portion 312 and the second plate portion 313 intersect.
[0083] The first plate portion 312 can extend in any direction in the plane where the first direction X and the second direction Y are located.
[0084] Exemplarily, the first plate portion 312 extends along the first direction X, the second plate portion 313 extends along the second direction Y, and the first plate portion 312 and the second plate portion 313 are perpendicular.
[0085] Exemplarily, the first plate portion 312 extends along the second direction Y, the second plate portion 313 extends along the first direction X, and the first plate portion 312 and the second plate portion 313 are perpendicular.
[0086] Exemplarily, the extending directions of the first plate portions 312 and the second plate portions 313 of each row of sound insulation ribs 30 in the first sound insulation rib group 311 can be different.
[0087] Exemplarily, the extending directions of the first plate portion 312 and the second plate portion 313 of the first sound insulation rib 31 in the same row may be different.
[0088] The above settings of the first plate portion 312 and the second plate portion 313 can be set to different shapes according to the actual usage situation and the simulation similarity of the engine sound.
[0089] In summary, by setting the first plate portion 312 and the second plate portion 313, the direction of sound refraction can be increased, so that after the sound is emitted from the sound generating unit 2 (see Figure 2 ), it needs to pass through more refractions before it can propagate out of the box body 1 (see Figure 2 ). And every time the sound passes through a refraction, it also passes through the barrier of the sound insulation rib 30 (see Figure 2 ), which can reduce the energy of the sound wave during the propagation process, so that the sound intensity gradually weakens, reducing the sound transmitted to the cockpit, thereby improving the experience of the driver and passengers.
[0090] Continuing to refer to Figure 5 , taking the first plate portion 312 perpendicular to the first wall surface 15 and the first plate portion 312 perpendicular to the second plate portion 313 as an example.
[0091] In a possible implementation manner, the first plate portions 312 of the two rows of first sound insulation ribs 31 are parallel.
[0092] Since the two rows of first sound insulation ribs 31 are arranged in a staggered manner, and at this time the first plate portions 312 of the two rows of first sound insulation ribs 31 are parallel, the sound can be repeatedly refracted between the two first plate portions 312, thereby reducing the sound wave energy and reducing the sound.
[0093] In a possible implementation manner, among the two rows of first sound insulation ribs 31, the second plate portion 313 of one row of first sound insulation ribs 31 is located on the side of the first plate portion 312 of one row of first sound insulation ribs 31 facing the other row of first sound insulation ribs 31, and the second plate portion 313 of the other row of first sound insulation ribs 31 is located on the side of the first plate portion 312 of the other row of first sound insulation ribs 31 facing one row of first sound insulation ribs 31.
[0094] In this way, a cavity with two openings is formed between the first plate portion 312, the second plate portion 313 of one row of first sound insulation ribs 31 and the first plate portion 312, the second plate portion 313 of the other row of first sound insulation ribs 31. The sound enters or leaves the cavity through these two openings. The probability that the sound remains in the cavity after entering the cavity and refracting is increased, and the energy of the sound wave is further lost after being refracted again, so that the volume can be further reduced.
[0095] Here, the interval size between the two rows of first sound insulation ribs 31 and the distance between two adjacent first sound insulation ribs 31 in the same row jointly determine the size of the opening.
[0096] The situation described above ignores the sound that acts on the first sound insulation rib 31 and penetrates the first sound insulation rib 31.
[0097] In a possible implementation, a slot is provided at the position of the plurality of first sound insulation ribs 31 corresponding to the sound generating unit 2, and a part of the sound generating unit 2 is accommodated in the slot. In this way, the installation of the sound generating unit 2 can be made more stable and the service life can be increased.
[0098] Combined Figure 2 and Figure 4 As shown, in a possible implementation, the plurality of sound insulation ribs 30 include a plurality of second sound insulation ribs 32, and the plurality of second sound insulation ribs 32 are arranged in an array on the surface of the second wall 16 facing the first wall 15 (see Figure 3 ).
[0099] In a possible implementation, the plurality of second sound insulation ribs 32 include a plurality of second sound insulation rib groups 321 arranged along the first direction X. The second sound insulation rib group 321 includes two rows of second sound insulation ribs 32 arranged along the first direction X, and each row of second sound insulation ribs 32 includes a plurality of second sound insulation ribs 32 arranged along the second direction Y. Among them, the first direction X and the second direction Y are perpendicular, and both the first direction X and the second direction Y are parallel to the second wall 16.
[0100] When the sound propagates to the second wall 16, it is weakened by the plurality of second sound insulation rib groups 321, multiple rows of second sound insulation ribs 32, and the plurality of second sound insulation ribs 32, reducing the energy of the sound wave. At the same time, the plurality of second sound insulation ribs 32 can increase the refraction length during the sound propagation process, thereby increasing the loss of the sound wave energy during the refraction process, reducing the sound transmission, and thus reducing the noise transmission towards the cockpit direction.
[0101] It should be noted that the sound propagated by the sound generating unit 2 does not pass through each second sound insulation rib group 321, each row of sound insulation ribs 30, and each second sound insulation rib 32. The refraction direction of the sound after contacting the second sound insulation rib 32 is determined by the shape of the second sound insulation rib 32.
[0102] Exemplarily, the two rows of second sound insulation ribs 32 are arranged in a staggered manner along the second direction Y. Thereby, when the sound emitted by the sound generating unit 2 propagates out of the box body 1, the sound insulation ribs 30 can increase the blockage of the sound, avoiding the sound from directly propagating out of the box body 1 through the gap of the sound insulation ribs 30, thereby improving the sound insulation effect.
[0103] Exemplarily, taking the application scenario of the embodiment of the present application as an example, the first direction X can be the width direction of the vehicle, and the second direction Y is the height direction of the vehicle.
[0104] Exemplarily, taking the application scenario of the embodiments of the present application as an example, the first direction X may be the height direction of the vehicle, and the second direction Y is the width direction of the vehicle.
[0105] In a possible implementation manner, the second sound insulation rib 32 includes a third plate portion 322 and a fourth plate portion 323.
[0106] In a possible implementation manner, the second sound insulation rib 32 may include one of the third plate portion 322 or the fourth plate portion 323. In order to avoid the sound outlet 12, only one of the third plate portion 322 or the fourth plate portion 323 may be provided.
[0107] Exemplarily, there is an included angle between the third plate portion 322 and the second wall surface 16. For example, the third plate portion 322 and the second wall surface 16 are perpendicular.
[0108] The fourth plate portion 323 is located on one side of the third plate portion 322, and the third plate portion 322 and the fourth plate portion 323 intersect.
[0109] Exemplarily, the third plate portion 322 and the fourth plate portion 323 intersect.
[0110] The third plate portion 322 may extend in any direction in the plane of the first direction X and the second direction Y.
[0111] Exemplarily, the third plate portion 322 extends along the first direction X, the fourth plate portion 323 extends along the second direction Y, and the third plate portion 322 and the fourth plate portion 323 are perpendicular.
[0112] Exemplarily, the third plate portion 322 extends along the second direction Y, the fourth plate portion 323 extends along the first direction X, and the third plate portion 322 and the fourth plate portion 323 are perpendicular.
[0113] Exemplarily, the extending directions of the third plate portion 322 and the fourth plate portion 323 of each row of the second sound insulation ribs 32 in the second sound insulation rib group 321 may be different.
[0114] Exemplarily, the extending directions of the third plate portion 322 and the fourth plate portion 323 of the second sound insulation ribs 32 in the same row of sound insulation ribs 30 may be different.
[0115] For the above settings of the third plate portion 322 and the fourth plate portion 323, they can be set to different shapes according to the actual usage situation and the simulation similarity of the engine sound.
[0116] In summary, by providing the third plate portion 322 and the fourth plate portion 323, the direction of sound refraction can be increased. As a result, after the sound is emitted from the sound generating unit 2, it needs to undergo more refractions before it can propagate out of the enclosure 1. Each time the sound undergoes refraction, it also passes through the barrier of the second sound insulation rib 32, which can reduce the energy of the sound wave during propagation, thereby gradually weakening the sound intensity and reducing the sound transmitted to the cockpit, thus improving the experience of the driver and passengers.
[0117] Taking the example where the third plate portion 322 is perpendicular to the second wall surface 16 and the third plate portion 322 is perpendicular to the fourth plate portion 323.
[0118] In a possible implementation, the third plate portions 322 of two rows of second sound insulation ribs 32 are parallel.
[0119] Since the two rows of second sound insulation ribs 32 are arranged in a staggered manner and the third plate portions 322 of the two rows of second sound insulation ribs 32 are parallel at this time, the sound can be repeatedly refracted between the two third plate portions 322, thereby reducing the sound wave energy and lowering the sound.
[0120] In a possible implementation, among the two rows of second sound insulation ribs 32, the fourth plate portion 323 of one row of second sound insulation ribs 32 is located on the side facing the other row of second sound insulation ribs 32 of the third plate portion 322 of one row of second sound insulation ribs 32, and the fourth plate portion 323 of the other row of second sound insulation ribs 32 is located on the side facing one row of second sound insulation ribs 32 of the third plate portion 322 of the other row of second sound insulation ribs 32.
[0121] In this way, a cavity with two openings is formed between the third plate portion 322 and the fourth plate portion 323 of one row of second sound insulation ribs 32 and the third plate portion 322 and the fourth plate portion 323 of the other row of second sound insulation ribs 32. The sound enters or leaves the cavity through these two openings. The probability that the sound remains in the cavity after entering and refracting increases, and the energy of the sound wave is further dissipated after being refracted again, thereby further reducing the volume.
[0122] Here, the size of the interval between the two rows of second sound insulation ribs 32 and the distance between two adjacent second sound insulation ribs 32 in the same row together determine the size of the opening.
[0123] The above-described situation ignores the sound that acts on the second sound insulation rib 32 and penetrates the second sound insulation rib 32.
[0124] Continue to refer to Figure 4 , a grille assembly can be provided at the sound outlet 12. The grille assembly can effectively prevent dust from entering the interior of the installation cavity and has a certain dust-proof effect.
[0125] Combined with Figure 3 and Figure 4, in a possible implementation, one end of the first sound insulation rib 31 is connected to the rear cover 14, the second sound insulation rib 32 is connected to the housing 13, and the end of the first sound insulation rib 31 far from the connection with the rear cover 14 contacts the end of the second sound insulation rib 32 far from the connection with the housing 13. Thus, the sound insulation rib 30 can support the box body 1 in the arrangement direction of the rear cover 14 and the housing 13.
[0126] In a possible implementation, the sound insulation rib 30 can also be arranged on the wall surface of the box body 1 connecting the first wall surface 15 and the second wall surface 16. For the arrangement method and beneficial effects, reference can be made to the case where the sound insulation rib 30 is arranged on the first wall surface 15.
[0127] In a possible implementation, the sound insulation rib 30 can also be arranged in an arc shape, and the concave direction of the sound insulation rib 30 is parallel to the first wall surface 15 and / or the second wall surface 16.
[0128] In a possible implementation, an absorption material, such as sound-absorbing cotton, can be arranged between the first sound insulation rib 31 and the second sound insulation rib 32. This can enhance its ability to absorb sound wave energy, further reduce the transmission of noise, and thus improve the experience of the driver and passengers.
[0129] Continue to refer to Figure 1 , in a possible implementation, the speaker 100 includes a bracket 4. The bracket 4 is connected to the box body 1, and the bracket 4 is suitable for receiving an external placement surface. The bracket 4 is suitable for connecting to a vehicle.
[0130] Exemplarily, the bracket 4 and the box body 1 can be connected by one of welding, bolt connection, snap connection, plug connection, buckle connection, magnetic connection, gluing or integral molding.
[0131] The bracket 4 can be installed at the front bumper of the vehicle, and the bracket 4 is detachably connected to the front bumper. Specifically, the bracket 4 can be connected to the front bumper by one of bolt connection, snap connection, plug connection, buckle connection, magnetic connection, gluing.
[0132] By installing the speaker 100 on the placement surface through the bracket 4, the speaker 100 can be removed, or installed at the front bumper of the vehicle, which is convenient for disassembly and assembly and maintenance.
[0133] In a possible implementation, the speaker 100 includes a wire passing tube 5. The wire passing tube 5 is connected to the box body 1, and a wire passing hole 51 is arranged in the wire passing tube 5. The wire passing hole 51 communicates with the installation cavity 11.
[0134] The wire passing tube 5 is connected to the box body 1, the wire passing hole 51 arranged in the wire passing tube 5 communicates with the installation cavity 11, and the wire passing tube 5 is used for passing a wire. The wire is externally connected to a power supply for supplying power to the sound generating unit 2 (see Figure 2 ).
[0135] Exemplarily, the threading pipe 5 can be connected to the wall surface of the box body 1 facing the vehicle body width direction.
