Description

A kind of telephone-type loud speaker with distance inducing function

Technical field

The utility model relates to loud speaker and technology for loudspeaker box, particularly relates to a kind of telephone-type loud speaker with distance inducing function.

Background technology

Telephone communication is mutually changed by acoustic energy and electric energy, and utilize " electricity " this medium to transmit a kind of communication technology of language.Two users will communicate, and two telephone sets, a pair connection gets up by the simplest form exactly; When the first speaker machine that picks up the telephone is talked facing to transmitter, the vibrational excitation air vibration of vocal cords, form sound wave, sound wave effect, on transmitter, makes it generation current, is called speech current; Speech current is sent in the receiver of counterpart telephone machine along circuit, and receiver effect and transmitter are just contrary, are sound wave current conversion, are reached in the ear of people by air.Like this, just the simplest communication process is completed.During coil electricity in loud speaker, its coil will produce magnetic field, and with under the magnetic field interaction of magnet, coil will vibrate, and vibration will be sounded, and is the stressed effect of electrical conductor in magnetic field in simple terms.

This case it is to be noted, the essence of current product remains the bluetooth small-size sound box of a band call function, Baffle Box of Bluetooth common at present when realizing call function, only be speaker mode (hands-free) call, dialog context bringing inconvenience with privacy.Therefore, for above aspect, need reasonably to improve prior art.

Utility model content

For above defect, the utility model provide a kind of easy to use, can switch between speaker mode and handset mode, sounding effect preferably with distance inducing function telephone-type loud speaker, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of telephone-type loud speaker with distance inducing function, comprise drain pan, cover plate and aluminium alloy panel, a component cavity is formed between described drain pan and cover plate, lid surface both sides are wherein offered a loudspeaker installing hole respectively and plate body between two installing holes are offered a holddown groove, component cavity internal fixtion below holddown groove installs mainboard, two loudspeaker installing hole inside install loudspeaker respectively, each loudspeaker outer surface arranges one deck speaker net, meanwhile, one deck aluminium alloy panel is laid in described cover plate central holddown groove outside;

Correspondingly, one of them loudspeaker is other is provided with distance-sensor, and another loudspeaker are other is provided with microphone; Described bottom shell arranges battery compartment, and trumpet bottom surface arranges low frequency vibrating diaphragm;

Described cover plate outward flange is bolted to above drain pan by some, and loudspeaker periphery arranges a circle aluminium alloy circle;

Bottom described drain pan, socket is set.

By the control of mainboard, when staff picks up audio amplifier near ear, after the distance-sensor in audio amplifier detects, signal can be sent to MCU(master controller), MCU is automatic switchback handset mode then, only has the other loudspeaker of distance-sensor to play with small volume; When distance-sensor leaves induction, the automatic switchback speaker mode of meeting, two loudspeaker are play with normal quantity simultaneously.

The beneficial effect of the telephone-type loud speaker of band distance inducing function described in the utility model is: good looking appearance, one of them loudspeaker is other is provided with distance-sensor, microphone is provided with on another loudspeaker side, when distance-sensor receives induction, the automatic switchback handset mode of meeting, the loudspeaker only having distance-sensor other are play; When distance-sensor leaves induction, can automatic switchback speaker mode, two loudspeaker are play simultaneously, easy to use, can switch between speaker mode and handset mode, sounding effect is better; No matter be the audio amplifier as listoning music, or as the receiver received calls, all very practical.
