Abstract

The utility model discloses a magnetic field induction loudspeaker which comprises a shell, wherein a convex mobile phone placing rack is arranged in front of the shell; a low-frequency induction oil, an audio power amplifier and a horn in sequential electrical connection are arranged in the shell; an external power interface is arranged behind the shell; and the audio power amplifier and the horn are electrically connected with the external power interface respectively. The magnetic field induction loudspeaker disclosed by the utility model has the advantages of novel design and reasonable structure; and based on the magnetic field induction principle, the magnetic field induction loudspeaker can amplify the out-sound of a mobile phone and then play the sound without using an audio connection wire so as to meet the entertainment need of people, and can save the cost and trouble of using an audio line.

Description

The magnetic field induction loud speaker
Technical field
The utility model relates to the magnetic field induction loud speaker that a kind of sound of mobile phone can being raised one's voice to its utmost amplifies and plays outward.
Background technology
Now, mobile phone becomes one of people's carry-on articles substantially, is often used in to listen an audio frequency, see recreation such as video.Though mobile phone all has the function of outer sound reproduction sound, the power that general mobile phone carries loudspeaker is little, and the sound of raising one's voice to its utmost outward is less, can not satisfy people's amusement demand.Existing audio amplifier, can be connected in the earphone jack of mobile phone by tone frequency channel wire, thereby sound is amplified broadcast by audio amplifier, though can possess the big outer sound reproduction sound that satisfies people's amusement demand, but generally all need to be connected between audio amplifier and the mobile phone, not only increase the cost in the use but also can increase operational trouble by tone frequency channel wire.
Summary of the invention
The purpose of this utility model provides a kind of magnetic field induction loud speaker, it is had need not tone frequency channel wire and connect the characteristics that the sound of mobile phone can being raised one's voice to its utmost amplifies and broadcasts outward.
For achieving the above object, technical solution adopted in the utility model is: the magnetic field induction loud speaker, comprise housing, and the housing front is provided with the mobile phone rack of protrusion; Be provided with the low frequency induction coil, audio-frequency power amplifier and the loudspeaker that electrically connect successively in the housing; The housing back is provided with external power interface; Described audio-frequency power amplifier and loudspeaker electrically connect with external power interface respectively.
Behind the magnetic field of the outer magnetic horn of the utility model by being used for outer sound reproduction sound in the coil-induced mobile phone of low frequency induction, and then convert audio electrical signal to, put broadcast outward by loudspeaker again to the audio-frequency power amplifier amplification that amplifies.
In order to improve the shelf-stability of loud speaker self and mobile phone, described housing is set to triangular prism shaped, so loud speaker self can stably be horizontally placed on table top, and mobile phone also can stably lean on a cylinder of triangular prism shaped housing.
In order to promote the sound effect of loud speaker, be provided with two loudspeaker in the housing, about dividing, two loudspeaker are arranged at two parallel side places of triangular prism shaped housing respectively, and it is netted that two parallel side of described triangular prism shaped housing are hollow out.
In order to make loud speaker be fit to the mobile phone of different-thickness, the mobile phone rack of described protrusion is set to movable drawing and pulling type mobile phone rack.
In order to control external power supply better, external power interface place, housing back also is provided with the switch of control external power supply on off operating mode and the display lamp that shows the external power supply on off operating mode.
The utility model modern design, rational in infrastructure, utilize the magnetic field induction principle, need not audio connecting cord, the sound of mobile phone can being raised one's voice to its utmost outward amplifies the back to be play, and satisfies people's amusement demand, and can save cost and the trouble of using tone frequency channel wire.
Description of drawings
Fig. 1 is a three-dimensional exploded view of the present utility model, also is that specification digest is with scheming.Each label is respectively among the figure: (1) housing, (2) mobile phone rack, (3) low frequency induction coil, (4) audio-frequency power amplifier, (5) loudspeaker, (6) external power interface, (7) switch, (8) display lamp.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the utility model magnetic field induction loud speaker comprises the housing 1 that is triangular prism shaped, and housing 1 front is provided with the drawing and pulling type mobile phone rack 2 of the activity of protrusion; Be provided with the low frequency induction coil 3, audio-frequency power amplifier 4 and the loudspeaker 5 that electrically connect successively in the housing 1; Housing 1 back is provided with external power interface 6, the switch 7 of control external power supply on off operating mode and the display lamp 8 that shows the external power supply on off operating mode; Described audio-frequency power amplifier 4 and loudspeaker 5 electrically connect with external power interface 6 respectively; Described loudspeaker 5 are arranged at the hollow out mesh side of triangular prism shaped housing 1.
