Abstract
The utility model relates to a sound box for a loudspeaker which can bear the impact of water current with definite pressure and the attack of a general object. The sound box for a loudspeaker is suitable for general natural environment, a loudspeaker arranged in a box body can be protected, and the loudspeaker can work normally. The sound box for a loudspeaker can be directly arranged on a motor vehicle as a sounding device for a speech buzzer. The sound box for a loudspeaker is characterized in that the loudspeaker (2) is arranged in a sealed sound box (1) made of waterproof materials, and a combining site between the loudspeaker (2) and the sealed sound box (1) is sealed with a flexible membrane (3) made of the waterproof materials; the outer side of the hole of the loudspeaker of the sealed sound box is provided with an acoustic horn (4); the center of the acoustic horn (4) is provided with a throat plug (5); a safety cover (6) and a drainage hole (7) are arranged.
Description
The utility model provides a kind of loudspeaker acoustic enclosure of water-fast flushing.
The motor vehicles that travel in current part area except that sending light signal and loudspeaker news sound, are brought into use the voice warning news sound of simulating human language when travelling turning or reversing.As " turn left, turn right, reversing " etc., this is certain to guaranteeing that traffic safety has play a part, wanting clear analog voice news to ring must use loud speaker as pronunciation device, because motor vehicle will often wash, and current various loud speaker and loudspeaker acoustic enclosure all can not bear the water impact of certain pressure, so this adopts applying of voice warning news sound to bring certain influence to motor vehicle.
The utility model provides a kind of loudspeaker acoustic enclosure that can bear the certain pressure water impact, can be installed on the motor vehicle, for drench with rain, the flushing of water logging bubble, water and general foreign material attack all can not damage sound box, makes the loud speaker of installing in the audio amplifier can operate as normal.
The utility model is achieved in that uses material impervious to water, as: bakelite, plastics, the audio amplifier that metal etc. are made, this audio amplifier removes and leaves a speaker hole, other binding site is hermetic, between loud speaker and audio amplifier speaker hole, be close to waterproof flexible membrane, this film can be used plastics, nylon, metals etc. are made, flexible membrane and audio amplifier speaker hole contact site scribble waterproof and sealing material, the part that is exposed to speaker hole can be in the certain limit porpoise, again loud speaker is connected the fastening speaker hole position that is installed to of flexible membrane, make it to form the hermetically sealed audio amplifier of dress loud speaker in, simultaneously loud speaker paper disc front is along circle and the flexible membrane air chamber of formation that is close together, because the flexible membrane one side is in the sealing audio amplifier, another side is outside stuffing box, the air that paper disc promotes in the air chamber when loud speaker pronounces makes the flexible membrane vibration, sound just is sent to outside the sealing audio amplifier, wherein, flexible membrane has played key effect, it can stop water to enter the sealing audio amplifier, and the sound that transmits loud speaker simultaneously is to extraneous.In order to prevent that flexible membrane is by water or the impact of other foreign material and damage and raising pronunciation efficient; in sealing audio amplifier speaker hole front a horn is installed; in horn central authorities a throat taps that is slightly larger than the loud speaker aperture is housed with a certain distance from the speaker hole position; it can stop effectively that current directly impact flexible membrane; improved pronunciation efficient simultaneously; the horn front end is equipped with the protective cover of a porous or porous misconstruction; be separated into thin spray after making the water column of impact enter horn; reduced the pressure of current; simultaneously can stop that foreign material enter horn, and sound after amplifying, horn is sent by protective cover.
Below be accompanying drawings the utility model specific embodiment:
Accompanying drawing (one) is the schematic diagram of waterproof loudspeaker acoustic enclosure.Loud speaker (2) is installed in the sealing audio amplifier (1); in the middle of loud speaker (2) and sealing audio amplifier (1) binding site, be close to and be sealed with flexible membrane (3); in sealing audio amplifier (1) the speaker hole outside horn (4) is housed; there is throat taps (5) in horn (4) central authorities; horn (4) opening part has the protective cover (6) of a porous misconstruction; horn (4) front end below has an osculum (7); when loud speaker (2) pronounces; the paper disc vibration is sent to flexible membrane (3) promotion air by the air chamber inner air and sounds, and is amplified by horn (4) after throat taps (5) is eliminated phase interference again and delivers to the external world.When foreign material seal audio amplifier (1) casing with the water impact that certain pressure is arranged; because casing itself has certain intensity; can not damage; so the loud speaker (2) in the sealing audio amplifier (1) can not damage; when water impact horn (4) front end of certain pressure; be protected stopping of cover (6); pressure descends; the current that enter horn (4) by protective cover (6) disperse to become spray; be subjected to stopping of throat taps (5) again, flexible membrane (3) is not damaged, because flexible membrane (3) has the sealing impervious nature; thereby water can not enter in sealing audio amplifier (1), and the water that accumulates in horn (4) is flow to outside the casing by osculum (7).Other foreign material are protected stopping of cover (6) simultaneously, can not enter horn (4), have finally protected the intact of loud speaker (2), make its energy operate as normal.
Claims (1)
- A kind of waterproof loudspeaker acoustic enclosure; it is characterized in that loud speaker (2) is installed in the sealing audio amplifier made from impermeable material (1); in the middle of loud speaker (2) and sealing audio amplifier (1) binding site, be close to and be sealed with the flexible membrane made from impermeable material (3); in sealing audio amplifier (1) the speaker hole outside horn (4) is housed; there is throat taps (5) in horn (4) central authorities; horn (4) front opening has the protective cover (6) of a porous or porous misconstruction outward, and horn (4) front end below has an osculum (7).
