The basin stand 1 is made of metal and has better strength and waterproof performance. The material of the stopper 4 is a foaming material, specifically, an electron radiation crosslinked polyethylene foaming material (IXPE), a polyethylene material (PE), a polyvinyl chloride material (PVC), a polyurethane material (PU) or a chemical crosslinked polyethylene foaming material (XPE). As shown in fig. 1 to 3, the vehicle-mounted outdoor speaker further includes a case 7, and a mesh enclosure 8, wherein core components (i.e., sound generating devices) of the vehicle-mounted outdoor speaker are disposed in the case 7, and the mesh enclosure 8 is connected to the case 7 to protect the core components and allow sound to radiate outwards. The basin frame 1, the positioning support plate 2, the magnetic circuit 3, the limiter 4, the voice coil 5 and the cone 6 shown in the figure form a sound generating device in the box body 7. The basin stand 1 is fixed on the box body 7 through a fastener 9, and the net cover 8 covers the outer side of the paper basin 6. It should be noted that, unlike conventional car speakers, the car-mounted outdoor speaker of the present embodiment is mounted outside the car, not in the passenger compartment of the vehicle, which is used to radiate sound outside the car. In one embodiment, the vehicle-mounted outdoor speaker is used for playing audio files such as music or making a welcome sound. In another embodiment, the vehicle-mounted outdoor speaker functions like a pedestrian warning device for giving warning sounds to pedestrians or simulating waves while the vehicle is running; but compare outdoor pedestrian's attention, this outdoor speaker volume is bigger, and speaker displacement is also bigger.
As shown in fig. 5 to 6, the basin stand 1 has a magnetic circuit connecting portion 11, and the magnetic circuit connecting portion 11 is provided with a connecting hole. The magnetic circuit connection portion 11 is laminated on the magnetic circuit 3, and the magnetic circuit 3 is fixed to the magnetic circuit connection portion 11. The magnetic circuit 3 includes a front plate 31, magnetic steel 32, and T-iron 33, and specifically, the magnetic circuit connection portion 11 is laminated on the front plate 31, and the magnetic circuit 3 has a connection protrusion 310 extending upward, and the connection protrusion 310 is inserted into the connection hole. Further, as shown in fig. 5 to 6, the cone frame 1 is provided with a cone 6, the cone 6 is connected with a voice coil 5, the front piece 31 and the magnetic steel 32 are arranged around the T iron 33, a magnetic gap into which the voice coil 5 can be inserted is formed between the outer walls of the T iron 33, and the lower part of the voice coil 5 is positioned in the magnetic gap. The front sheet 31 is formed with a coupling protrusion 310, and the thickness of the front sheet 31 at the coupling protrusion 310 is equal to the thickness of the other portions of the front sheet 3.
As shown in fig. 2 to 3, the positioning support plate 2 is fixedly connected with the inner end of the voice coil 5, and the outer edge of the positioning support plate 2 is fixedly connected with the basin frame 1. The voice coil 5 is stably moved up and down by the positioning support piece 2, and is prevented from shaking left and right.
As shown in fig. 2 to 3, the stopper 4 is made of a foam material, is disposed inside the connecting protrusion 310, is disposed below the positioning support 2 and near the inner edge of the positioning support 2, and has an upper end facing the positioning support 2 and a lower end facing the magnetic circuit 3 or the magnetic circuit connecting portion 11. In the embodiment, the lower end part of the limiter 4 is connected to the magnetic circuit connecting part 11, and a space is reserved between the upper end part and the positioning support piece 2; in other embodiments, the upper end of the stopper 4 is connected to the positioning bracket 2, and the lower end is spaced from the magnetic circuit 3 or the magnetic circuit connecting portion. When the loudspeaker is subjected to external force such as water pressure and the like, the loudspeaker vibration system can be extruded to exceed normal working displacement, and the limiter 4 contracts and deforms to play a limiting role.

When the loudspeaker receives external force, such as under the condition of water pressure, the loudspeaker vibration system can be extruded and surpass normal working displacement, and the stopper begins to play spacing effect this moment, changes overload operating condition into. In overload working state, the limiter 4 is pressed between the positioning support piece 2 and the magnetic circuit 3 or the magnetic circuit connecting part 13, so as to avoid irreversible damage caused by excessive deformation of a vibration system of the loudspeaker.
Above-mentioned on-vehicle outdoor speaker is in sound production in-process: the lower part of the voice coil 5 is inserted into the magnetic gap, an audio electric signal is introduced, and the voice coil 5 makes cutting magnetic induction line movement along with current change under the action of a magnetic field, so that the cone 6 is driven to vibrate and sound; when external extrusion or impact is received, particularly in a soaking test, the requirement of 1m and half hours under water needs to be met; if ponding or rainwater splashes onto the cone 6, the cone 6 may collapse downwards, and at this time, the vibration system can be "towed" by the limiter 4, and the limiter 4 can buffer the cone 6, so as to prevent the cone 6, the voice coil 5 or the positioning support plate 2 from being damaged due to excessive deformation.
The vehicle-mounted outdoor loudspeaker has at least the following advantages;
the stopper 4 is a foaming material to buffer excessive deformation when the vibration system of the speaker is subjected to an external force. In the overload working state, the limiter 4 is extruded between the positioning support piece 2 and the magnetic circuit 3 or the magnetic circuit connecting part 11, and the vibration system of the loudspeaker can be prevented from being irreversibly damaged due to excessive deformation by supporting the positioning support piece 2.
