Abstract
The utility model discloses a flat moulded case loudspeaker box. The flat moulded case loudspeaker box comprises a housing, a low-frequency loudspeaker, a sound production board and an exciter. The low-frequency loudspeaker is fixed on the housing. A cavity is formed in the housing. The sound production board is located in the cavity. The exciter is installed on the sound production board. The periphery of the sound production board is provided with an elastic device. The sound production board is connected with the housing through the elastic device. An interval exists between the exciter and the low-frequency loudspeaker. The exciter is connected with the low-frequency loudspeaker through a wire. The flat moulded case loudspeaker box has the following advantages that the sound production board is fixed in the housing through the elastic device, and when the loudspeaker box is in work, the exciter will be vibrated along with the vibration of the sound production board, so the advantage of better low-frequency effect can be realized.
Description
Technical field
The utility model relates to a kind of audio amplifier, especially relates to a kind of flat board and moulds the shell audio amplifier.
Background technology
Flat board is moulded the shell audio amplifier and is had characteristics lightweight, easy to carry, is applicable to small-sized performance occasion and uses, and configures economical and practically, and practicality is very extensive.Excitation that current flat board is moulded in the shell audio amplifier is fixedly mounted in casing, can reduce the low-frequency effects of woofer, and tonequality is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of flat board that can effectively increase low-frequency effects and moulds the shell audio amplifier.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of flat board is moulded the shell audio amplifier, comprise housing, Low frequency horn, phonation board and excitation, described Low frequency horn is fixed on housing, it is characterized in that thering is cavity in described housing, described phonation board is positioned at described cavity, described excitation is arranged on described phonation board, described phonation board surrounding is provided with elastic device, described phonation board is connected with housing by described elastic device, between described excitation and described Low frequency horn, a segment distance is arranged, described excitation is connected with Low frequency horn by wire.
Described phonation board is honeycomb aluminum plate.
Housing comprises fore shell and back cover, on described fore shell, web plate is installed, and described Low frequency horn is arranged on described back cover.
The MP3 player is installed on housing.
Be provided with power amplifier module and wireless module in described housing, described power amplifier module is connected with wireless module.
Compared with prior art, the utility model has the advantages that phonation board is fixed in housing by elastic device, when audio amplifier is worked, excitation can shake along with the phonation board vibrations, therefore has better low-frequency effects.
