Abstract
The utility model discloses an earphone loudspeaker box containing functions of automatic switchover and automatic volume adaptation. The earphone loudspeaker box mainly depends on earphones. Externally-placed loudspeaker boxes are disposed on the outer sides of the two earmuffs of the earphones. An infrared sensor probe is disposed on the lower part of a right earmuff of the earphones. An externally-hung battery is disposed on the lower part of a left earmuff of the earphones. A control unit is placed on an earphone supporting frame and comprises an infrared detection comparison module, an audio switching module, a power amplifier module, and a controller module. The earphone loudspeaker box is capable of automatically judging a current operating state and determining an earphone mode or an externally-placed loudspeaker box mode. And according to the two modes, the earphone loudspeaker box is automatically adapted to playing volume. The earphone loudspeaker box containing a function of automatic switchover combines characteristics of an earphone and a loudspeaker box and is a brand-new mobile music playing externally-placed device.
Description
Technical field
The utility model relates to mobile broadcast field.
Background technology
Music is the first-selection of many young men leisure instantly.But in the selection of earphone and audio amplifier, tend to make the people extremely to be entangled with.Earphone can allow own enjoy music, but is difficult to share with the people; Audio amplifier tonequality is better, can all listen, but can influence other people in some occasions.At ordinary times also the someone attempt that earphone is used as audio amplifier and use, exactly earpiece volume is transferred to maximum, and earmuff is turned up, do like this that not only volume is limited, and tonequality is also poor, accidentally also the earphone that reaches max volume can be taken on the head to the major injury ear sometimes.If have a product can have the function of earphone and audio amplifier simultaneously, and can judge present residing state automatically, decision is headset mode or the playback of audio amplifier pattern, adapts to volume under these two kinds of patterns automatically, and these problems just can be readily solved so.
The utility model content
The purpose of this utility model is to make a player that is convenient for carrying; It has earphone and two kinds of broadcasts of audio amplifier simultaneously; And can automatically switch between two kinds of patterns and the automatic volume that adapts under two kinds of patterns.
Technical solutions of the utility model are as follows:
A kind of earphone audio amplifier with automatic switching function, comprise earphone, outer playback case, described earphone audio amplifier is playback case outside the earphone outside that bracing frame is arranged installs additional, playback case L channel (3) outside earphone L channel (1) outside installs additional, playback case R channel (4) outside earphone R channel (2) outside installs additional; Play and two kinds of play mode of audio amplifier mode playback by control unit (6) automatic switchover headset mode.
Described earphone audio amplifier also comprises the control unit (6) that is placed on the earphone bracing frame, the infrared sensor probe (5) of earphone right side earmuff below.
Described control unit (6) comprising: infrared detection comparison module (7), audio frequency handover module (8), power amplifier module (9) and controller module (10).
Described infrared comparison module (7) sends to controller module (10) with comparative result, and control module (10) is sent instruction automatically according to comparison result audio frequency handover module (8) is switched.
The beneficial effect of utility model:
This has the earphone audio amplifier of automatic switching function in conjunction with the characteristics of earphone and audio amplifier, is that a kind of brand-new mobile music is put equipment outward.When the user put on earphone, the infrared sensor probe sent signal, and control unit carries out signal analysis, switches by circuit, finally plays with headset mode.When the user took earphone, the infrared sensor probe sent signal, and control unit will be implemented outer playback box mode and play.
Multiple mode is adopted in the audio frequency input, adapts to different playback equipments, such as computer, MP3 and mobile phone etc.Increase compact battery simultaneously and give power devices, make outer playback case effect more perfect.

1, earphone L channel; 2, earphone R channel; 3, outer playback case L channel; 4, outer playback case R channel; 5, infrared sensor probe; 6, control unit; 7, infrared detection comparison module; 8, audio frequency handover module; 9, power amplifier module; 10, controller module; 11, external power supply; 12, audio frequency input.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
The utility model mainly is support with the earphone, two earmuff outsides of earphone are outer playback casees, there is infrared sensor probe (5) earmuff below, earphone right side, there is external power supply (11) earmuff below, earphone left side, place control unit (6) at the earphone bracing frame, control unit comprises: infrared detection comparison module (7), audio frequency handover module (8), power amplifier module (9) and controller module (10).
Audio frequency input (12) inserts playback equipment, if put on earphone, infrared sensor probe (5) detects signal, this signal is transferred to infrared comparison module (7) and compares, controller module (10) sends instruction according to comparison result, audio frequency handover module (8) switches, and audio input signal is connected earphone play passage; Earphone L channel (1) and earphone R channel (2) are sounded; If take earphone, infrared sensor probe (5) detects signal; This signal is transferred to infrared comparison module (7) compares, and controller module (10) sends instruction according to comparison result, and audio frequency handover module (8) switches, and audio input signal is connected power amplifier module (9); Power amplifier module (9) in the control unit (6) drives audio amplifier mode playback passage; Outer playback case L channel 3 and outer playback case R channel 4 are sounded.
Claims (3)
1. the earphone audio amplifier with automatic switching function comprises earphone, outer playback case, it is characterized in that:
Described earphone audio amplifier is playback case outside the earphone outside that bracing frame is arranged installs additional, playback case L channel (3) outside earphone L channel (1) outside installs additional, playback case R channel (4) outside earphone R channel (2) outside installs additional;
