Abstract
The utility model discloses a bass loudspeaker with self-compensation of gravity, comprising a shell body. The lower end of the shell body is provided with a tibial membrane, the middle part of the tibial membrane is provided with a magnet, an iron core is arranged in the shell body, the iron core is sheathed with a coil curl, the upper part of the iron core is sheathed with a circuit board, and the circuit board is connected with the coil curl. The bass loudspeaker with self-compensation of gravity has the advantages of simple structure, low cost, convenient maintenance, etc. Since the tibial membrane of the bass loudspeaker with self-compensation of gravity is not easy to deform, the service life of the bass loudspeaker is extended.
Description
Technical field
The utility model relates to a kind of stereo set, is a kind of gravity self compensation woofer.
Background technology
At present, in the existing sound system, setting up has subwoofer, be woofer, producing sense of direction during for fear of the woofer sounding influences tonequality, usually the front vertical ground of woofer sound film is installed up or down, but, the sound film so is installed, and the sound film can crooked up or down deformation under the long term of gravity, and the sound film damages, the lost of life of woofer thereby cause.Some producer install the gravity compensation circuit additional on the basis of original loadspeaker structure, but this can make the woofer complex structure for preventing sound film generation deformation, and failure rate raises, and maintenance difficulty is big.
Summary of the invention
The purpose of this utility model has provided a kind of gravity self compensation woofer, adds magnet on its sound film, offsets the effect of gravity to the sound film with magnetic force, can prevent effectively that the deformation under gravity of sound film from damaging, and can prolong the useful life of woofer.
The purpose of this utility model is achieved through the following technical solutions: gravity self compensation woofer, and it has housing, and the sound film is installed in the lower end of housing, magnet is installed at the middle part of sound film, and iron core, suit coil on the iron core are installed in the housing, the top cover device, circuit board of iron core, circuit board is connected with coil.Iron core is installed in the enclosure interior suit transmission sleeve pipe, transmission sleeve pipe.The sound film is installed in the upper end of housing.Circuit board comprises substrate and four metallic conductors, and four metallic conductors evenly are installed on the substrate, and two terminals of coil are connected with metallic conductor respectively.Between two metallic conductors resistance is installed, between two metallic conductors electric capacity is installed in addition.Phase plug is installed in the bottom of sound film.
Good effect of the present utility model is: it has advantages such as simple in structure, cheap for manufacturing cost, easy to maintenance, and, because its sound film is difficult for deformation takes place under gravity, make increase the useful life of woofer.
Description of drawings
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
Gravity self compensation woofer, it has housing 13, and sound film 9 is installed in the lower end of housing 13, and magnet 10 is installed at the middle part of sound film 9, and iron core 4 is installed in the housing 13, and suit coil 12 on the iron core 4, the top cover device, circuit board of iron core 4, circuit board is connected with coil 12.Housing 13 inner suit drive sleeve pipes 11 are installed iron core 4 in the transmission sleeve pipe 11.Sound film 7 is installed in the upper end of housing 13.Circuit board comprises substrate 3 and four metallic conductors, and metallic conductor 1 evenly is installed on the substrate 3, metallic conductor 5, and metallic conductor 14 and metallic conductor 15, two terminals of coil 12 are connected with metallic conductor 5 with metallic conductor 1 respectively.Resistance 2 is installed between metallic conductor 14 and the metallic conductor 1, electric capacity 6 is installed between metallic conductor 5 and the metallic conductor 15.Phase plug 8 is installed in the bottom of sound film 9.Transmission sleeve pipe of the present utility model 11 is made by nonmetallic materials.Electric capacity 6 of the present utility model can absorb the electric current that is added on woofer coil 12 two ends suddenly when start, can play the effect of protection coil 12.When having big electric current to pass through in the coil 12 of the present utility model, resistance 2 can fusing play 12 effects of protection coil; And electric capacity 6 can filter out the high pitch part in the audio signal, makes bass plentiful more pure.The utility model is installed sound film 7 can overcome bass sense of direction raising tonequality.When the utility model uses, only need audio output is connected with metallic conductor 15 with metallic conductor 14 respectively and get final product.
