New description: [New technical field] The present invention relates to an earphone, and particularly relates to a earphone with a speaker function. [Prior Art] Both the earphone and the speaker include a la. Eight, both are sounding devices that convert audio signals into sound. The earphones are small and the power is small. The sound is small. When used, it is often hung on the ear or worn on the head and attached to the ear hole. The speaker is large in size, and the power is large, and the sound is loud, and it can produce a very impressive physical experience. With the diversification and improvisation of people's tastes, the enjoyment of music and other sounds may have different situational requirements with impromptu demand, such as listening - headphones, immediately 'two = speakers; even the same - the first song, this paragraph I want to hear the machine, and I want to use the speaker to listen. At present, there are a variety of earphones and speaker converters on the market. The plugs of the earphones and the speakers are plugged into the conversion agency, which is only suitable for both the machine and the speaker. However, this converter is only suitable for both. In the case of headphones and speakers, it still cannot meet people's needs. China Patent 2_2〇1375G7· 2 "Audio headphones that can be used as speakers", and both have been opened - _ with headphones and speakers, and headphones, but by setting two sets of outer eight on the headset, that is The realization of the set == another 'container wire to achieve, so, _ will increase the headset's ability to increase the head's load bearing capacity, lack of comfort. 5 M354964 [New content] The purpose of this creation is to provide a speaker with a speaker function for the deficiencies of the prior art, which can realize the random switching between the earphone and the speaker function through L. In order to achieve the above objectives, the author has the following technical solutions: a speaker with a speaker function, at least two earmuffs, a built-in gamma gamma for each earmuff, and a lead with a plug, electrically connected to the potential of the two ears. The lead wire is provided with an audio discrimination amplifier electrically connected between the plug and the two coffees; and a switch for switching different audio transmissions: power 彳§ to two. The above connector can be an RCA audio plug equipped with a conventional earphone. For an audio output device (domain brain host) with an interface and the USB mask audio output function, the above plug can be a (four) plug, and the audio signal conversion interface is connected in series between the hoe and the audio function H. On (10). The audio-visual technology of Yinyin Ling Cai has been carefully edited, _ Jingling face will be replaced by the age-old reading, and then the analog audio amplifier will be output to •, at this time the function of the earphone is Speaker mode, with high power, large sound characteristics. In order to make the function of the headset for the headset mode, that is, the potential eight round _ small, sound apricot, then switch _ to cut the same audio output scale to gamma, The mode of the night is such as switching a clothes reducer, or the magnification of the audio power amplifier is the input of a team directly connected to the audio wheel output of the USB audio conversion interface, -= cutting the main function is different audio of the city Turn the power signal to two, ~ delete the fine-grained to achieve the purpose of switching out 6. M354964 different audio output power. The utility model can also be a sliding switch of a mechanical structure, or a button switch, or a switch of a rotating mechanical structure with a volume adjustment function. Preferably, the audio power amplifier, the audio conversion interface, and the like of the present invention can be set in any of the ear-ears; or can include a cover box for the audio power amplifier and USB audio. An audio signal processing electronic component such as a conversion interface is wrapped therein; and the switching switch may be disposed in the covering box. In order to make the user use the creation more flexibly, the cover box can include a jack for the audio input interface for the connection plus the sound, and the audio wheel out connector with the external audio source is connected to the audio. When you turn in the interface, all the (4) audio converters in the original circuit of the headset are switched to the audio input interface. In order to make the creation of the second audio output power of 220 volts, the cover box can be set up with a jack, the jack = grab (five) for the continuous shooting for the money to discriminate the external power frequency amplifier to obtain a larger Output Power. In addition to the structure of the conventional ear-hook headphones, this creation also

Through the USB bit analog converter DAC, the digital audio power amplifier 6 inside the digital audio and video audio conversion interface 7 is enlarged and turned into a secret audio money, and then the analog type has a large power and a large sound speaker characteristic; The sound of the rotation of the scales is the analogy of the output of the USB audio conversion interface 7; when the switch 8 is switched to the headphone mode, the output is directly output to the taste M3, and at this time, the number of the sound is not the audio power. The amplifier handles the characteristics of the small earphone. The sound has a small output power, and the sound is called another small audio conversion interface 7. The switch is 89, and the structure is: the Cong plug U, the combined working circuit At this time, the switch 8 is turned on and the device 6 and the potential 8 are sequentially connected to the mechanical structure of the adjustable resistor, the progressive switch = the reduced input, or the digital audio signal generated by the rotary audio output function of the switch.

This makes it easy to implement the switching function. In addition, according to the connection relationship between the earmuff and the headband and the linkage principle of the switch, the τ can be a foldable or detachable headband, that is, any part of the headband body (preferably the head) The middle portion of the belt body is provided with a folded structure or a detachable structure to form the headband to form two relatively movable parts. The relative movement between the two parts respectively drives an earmuff movement to cause the two ear cups to change in position. _, (10) need to use the ear and speaker mode; the folding structure or the detachable structure _ can also be linked with the tang to achieve the purpose of automatically switching the mode of operation of the earphone. Moved, as shown in the ninth figure, J is still the rear wall of the earmuff 2 can be equipped with a venting hole 21, and the inner cavity of the earmuffs constitutes a transmission line speaker of Helm Subtracting (HellDh〇ltZ) resonator structure 22, the cross-sectional side of the transmission line is regarded as a concentric annular ring with a vent hole axis 13 M354964 as a heart circle, an ellipse; and a sound absorbing material 23 is filled in the inner cavity of the ear cup to Get better sound quality.
