Abstract
The utility model discloses a pronouncing device combined with a container cavity to produce resonance. A power supply circuit board is arranged in a shell; a ring storage battery is arranged on the lower side of the power supply circuit board; a loudspeaker is arranged at the bottom end of the storage battery; a centre bolt is arranged at the upper end of the loudspeaker, and a frame is arranged at the top end of the loudspeaker; a cone frame made of metal material is arranged in the frame; an elastic grab hook or clamping hook is arranged on the outer wall of the cone frame, plastic rubber, or an elastic metal sleeve ring or ferrule is arranged on the edge of the cone frame; and a mounting and fixing groove is formed on the plastic rubber, the sleeve ring or ferrule. During assembly, an outer opening of the container is formed in the fixing groove of the sleeve ring or the ferrule of the cone frame, and a vibrating paper cone of the loudspeaker plays toward the inner part of the container through an inner opening of the container, so that the container cavity can produce resonance and make sonorous and sweet sounds.
Description
Technical field:
The utility model relates to a kind of stereo set, and definite a kind of combining container cavity of saying so produces the pronunciation device of resonance sympathetic response.
Background technology:
The stereo set of selling in the market and using all is furnished with various audio amplifier, the audio amplifier that these are different, because its material and structure Design limitation, the lower tone that sends, tone distortion, not loud and clear do not reach desirable acoustics, and carry inconvenience because of bulky.
The utility model content:
The purpose of this utility model provides a kind of pronunciation device by the sympathetic response of external container generation resonance, and to solve traditional audio amplifier lower tone, tone distortion, not loud and clear, volume is big, carries the defective of inconvenience.
Scheme of the present utility model is made up of housing, power supply circuit board, annular storage battery, centre bolt and loud speaker, power supply circuit board is set in the housing, and power supply circuit board comprises audio power amplifier device, MP3 audio decoding apparatus, FM FM receiver IC module, external holder data fetch device, bluetooth receiving system, remote-receiver.The downside of power supply circuit board is provided with annular storage battery, and the bottom of storage battery is provided with loud speaker, and the upper end of loud speaker is provided with centre bolt.Described loud speaker is made up of magnetic loop system, vibrational system and support auxiliary system three parts, magnetic loop system is provided with permanent magnet and magnetic conductive board, vibrational system is provided with cone and voice coil loudspeaker voice coil, support auxiliary system is provided with framework and basin frame, top at loud speaker is provided with framework, and permanent magnet is housed in the framework, and annular storage battery is sleeved on the outside of framework, junction at storage battery and framework is provided with draw-in groove, becomes flexible preventing.The upper end of framework is provided with screw, be connected with centre bolt in the screw, loud speaker and power supply circuit board are fixed in the housing by centre bolt, the bottom side of permanent magnet is provided with magnetic conductive board successively, voice coil loudspeaker voice coil, the basin frame, cone and dust cap, the basin frame is made by metal material, on the outer wall of basin frame, be provided with elasticity grapple or buckle, plastic cement is set on the edge of basin frame or the rubber-like metal collar or lasso are set, also can elasticity grapple or buckle be set at the downside of the case body of this device, the described plastic cement and the collar or lasso make according to the container bore, the plastic cement and the collar or lasso are provided with and install and fix groove, during assembling the collar extension of container are placed in the holddown groove of the collar of basin frame or lasso.The vibration cone of loud speaker is play in container cavity by the internal orifice of container, and container cavity generation resonance is empathized, and just sends loud and clear beautiful sound.The also available conventional beverage pop can of described container replaces, and the thickness of the physical dimension of this tank body, shape and tank skin all reaches the coupling of the best with the pronunciation of loud speaker, so just obtain best acoustics.
The utility model is simple in structure, designs ingeniously, as long as supporting container cavity is installed or is gathered materials on the spot and select for use discarded pop can slack tank to cooperate assembling with it, promptly obtains acoustics extraordinary.
Be described in further detail below in conjunction with accompanying drawing.
