Abstract
The utility model relates to a chord loudspeaker which comprises a casing, wherein both sides of the casing are respectively provided with a back cavity and a front cavity, a receiver voice coil and a receiver vibrating diaphragm are arranged in the back cavity, a loudspeaker voice coil and a loudspeaker vibrating diaphragm are arranged in the front cavity, the receiver voice coil and the loudspeaker voice coil are respectively conducted with an integrated circuit board through conducting wires, the integrated circuit board is arranged on the casing, the space between the back cavity and the front cavity is provided with a through hole, and the back cavity and the front cavity can be conducted by the through hole. The utility model has the advantage that the cavity of the receiver vibrating diaphragm is conducted with the cavity of the loudspeaker vibrating diaphragm to change the integrated process of a composite diad chord loudspeaker. Consequently, the utility model changes the sound defect of a previous composite diad loudspeaker caused by the technological abuse because of the structural defect of the previous composite diad loudspeaker. The composite diad cord loudspeaker has the advantages of reasonable structure and good tone quality.
Description
Technical field
The utility model relates to a kind of loud speaker, especially a kind of chord loud speaker that is used for mobile phone.
Background technology
At present, used combined type two-in-one loudspeaker on the mobile phone, both sides generally respectively have a chamber respectively, are provided with the receiver vibrating membrane in one of them chamber, are provided with loudspeaker vibrating diaphragm in another chamber.And two chambers are separate, not conducting each other.Such loud speaker sound matter is bad, and result of use is poor.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and the chord loud speaker of a kind of ante-chamber, back cavity conducting is provided.
The utility model solves the technical scheme that its technical problem adopts: this chord loud speaker, comprise housing, the housing both sides have back cavity and ante-chamber respectively, be provided with receiver voice coil loudspeaker voice coil, receiver vibrating diaphragm in the back cavity, be provided with loudspeaker voice coil, the diaphragm of loudspeaker in the ante-chamber, receiver voice coil loudspeaker voice coil, loudspeaker voice coil are respectively by lead and the surface-mounted integrated circuit conducting of being located on the housing; Have through hole between back cavity and the ante-chamber with back cavity, ante-chamber conducting.
The effect that the utility model is useful is: the utility model ante-chamber and back cavity are about to the chamber at receiver vibrating membrane place and the chamber conducting at loudspeaker vibrating diaphragm place by the through hole conducting.Rational in infrastructure, sound matter is good, and effect is remarkable, applied range.
Description of drawings
Fig. 1 is that the utility model master looks the sectional structure schematic diagram;
Fig. 2 is the plan structure schematic diagram that the utility model removes the diaphragm of loudspeaker;
Fig. 3 is the structural representation of looking up that the utility model removes the receiver vibrating diaphragm.
Description of reference numerals: housing 1, surface-mounted integrated circuit 2, back cavity 3, receiver voice coil loudspeaker voice coil 4, receiver vibrating diaphragm 5, through hole 6, loudspeaker voice coil 7, the diaphragm of loudspeaker 8, ante-chamber 9, lead 10, loud speaker steam vent 11.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This chord loud speaker, comprise housing 1, housing 1 both sides have back cavity 3 and ante-chamber 9 respectively, be provided with receiver voice coil loudspeaker voice coil 4, receiver vibrating diaphragm 5 in the back cavity 3, receiver voice coil loudspeaker voice coil 4 is connected on the receiver vibrating diaphragm 5, be provided with loudspeaker voice coil 7, the diaphragm of loudspeaker 8 in the ante-chamber 9, loudspeaker voice coil 7 is connected on the diaphragm of loudspeaker 8.Receiver voice coil loudspeaker voice coil 4, loudspeaker voice coil 7 are respectively by lead and surface-mounted integrated circuit 2 conductings of being located on the housing 1; Surface-mounted integrated circuit 2 is connected with power supply by lead 10.Have loud speaker steam vent 11 on the housing 1; Have through hole 6 between back cavity 3 and the ante-chamber 9 with back cavity 3, ante-chamber 9 conductings.
The chamber at the utility model receiver vibrating membrane place and the chamber conducting at loudspeaker vibrating diaphragm place are handled, make the integrated artistic of the two-in-one chord loud speaker of combined type change take place, thereby changed combined type two-in-one loudspeaker in the past because the shortcoming of this body structure causes the drawback of technology to cause defective on the combined type two-in-one loudspeaker sound in the past.The two-in-one chord loadspeaker structure of this kind of combined type is reasonable, and sound matter is good, and effect is remarkable, applied range.
