Abstract

The utility model relates to a stereophonic earphone which is cool in summer and warm in winter and belongs to a small electric appliance. The stereophonic earphone comprises a left earphone, a right earphone and a connect piece which can connect the left earphone and the right earphone together. The left or right earphone consists of a vocalization part, a fixing frame and a protection jacket. The utility model is characterized in that a semiconductor cooling chip die based on the peltier effect is installed on the fixing frame in the protection jacket. The semiconductor cooling chip die is powered by a player connected with the earphone and has positive and negative connect function. When being negatively connected, the semiconductor cooling chip die is working in the warming state. The stereophonic earphone solves the problem that an earphone used in winter can not be used in summer for a long time, and the earphone has no warming function in the cool state, thereby affecting the appreciation of people. The utility model provides fans with an earphone with simple structure and convenient use, which is warm in winter and cool in summer.

Description

Cool in summer and warm in winter type stereo earphone

Technical field

The utility model relates to a kind of earphone, especially a kind of stereophone of energy cover human ear, specifically a kind of cool in summer and warm in winter type stereo earphone that is suitable for using throughout the year.

Background technology

Earphone is the requisite converter tools that a kind of energy music appreciating does not influence other people again, and at present, nearly all amusement equipment such as MP3, MP4, broadcast receiver, mobile phone etc. all are furnished with earphone.At student gang and working people, earphone production firm also develops a kind of being worn over specially and specializes in the earphone with earflap function that uses winter on the ear, but this earphone is just being worn or can not really play thermal effect cold season, therefore the user is few, even add thick heat insulation sheath, its heat insulation effect is also undesirable, and this earphone can't use in summer at all, if therefore can develop a kind of winter can generate heat, can freeze summer, the earphone that reaches purpose cool in summer and warm in winter is the hope that fan's door is dreamed of, but according to the knowledge of the applicant, and still not having Related product at present can for choosing.

Summary of the invention

The purpose of this utility model is too cold at the use in winter of existing earphone, and use too hot problem summer, designs a kind of stereophone that can regulate the cool in summer and warm in winter type of temperature automatically.

The technical solution of the utility model is:

A kind of cool in summer and warm in winter type stereo earphone, form by the connector that comprises left earphone, right earphone and connect left and right earphone, a described left side or right earphone are made up of sounding parts, fixed mount and sheath, it is characterized in that in sheath, the semiconductor refrigeration chip based on peltier effect is installed on the fixed mount, described semiconductor refrigeration chip is by the player power supply that links to each other with earphone and have positive and negative connection function, promptly described semiconductor refrigeration chip works in refrigerating state when just connecing, when reversal connection, described semiconductor refrigeration chip works in heated condition.

Connector at the left and right earphone of described connection is equipped with solar cell, the output termination semiconductor refrigeration chip of this solar cell.

Temperature sensor also is installed on the described fixed mount, and temperature sensor links to each other with the control circuit of semiconductor refrigeration chip.

The beneficial effects of the utility model:

The utility model has solved the earphone out of use problem of using winter for a long time in summer, and earphone does not have heat insulation function under cold state, influences the problem that people appreciate use, for fans provide a kind of simple in structure, earphone easy to use, cool in summer and warm in winter.

Earphone of the present utility model can be adjusted the operating state of semiconductor chip automatically according to ambient temperature, simultaneously can use solar energy as working power, and the power consumption of Jie Yueing greatly can prolong service time of amusement equipment.

Description of drawings

Fig. 1 is a contour structures schematic diagram of the present utility model.

Fig. 2 is the sectional structure schematic diagram of a left side of the present utility model or right earphone.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, 2.

A kind of cool in summer and warm in winter type stereo earphone is made up of the connector 2 that comprises left earphone, right earphone 1 and connect left and right earphone 1, as shown in Figure 1.A described left side or right earphone 1 are made up of sounding parts 3, fixed mount 4 and sheath 5, as shown in Figure 2, semiconductor refrigeration chip 6 based on peltier effect is installed in sheath 5, on the fixed mount 4, described semiconductor refrigeration chip 6 is by the player power supply that links to each other with earphone or by solar cell for supplying power, its control circuit has positive and negative connection function (can realize by toggle switch), promptly described semiconductor refrigeration chip 6 works in refrigerating state when just connecing, when reversal connection, described semiconductor refrigeration chip 6 works in heated condition.For electrical energy saving, reduce the consumption of semiconductor chip to power supply, during concrete enforcement, also can be on a described connection left side, connector 1 place of right earphone is equipped with solar cell 7, the output termination semiconductor refrigeration chip of this solar cell, in order to realize the automatic work of semiconductor refrigeration chip, also can be on fixed mount 4 mounting temperature sensor 8, temperature sensor 8 links to each other with the control circuit of semiconductor refrigeration chip 6, when temperature is lower than set point, make semiconductor refrigeration chip 6 work in mode of heating (promptly close one side heating with people's ear, the another side refrigeration), when temperature is higher than set point, make semiconductor refrigeration chip 6 work in refrigeration modes (promptly close one side refrigeration, another side heating) with people's ear.

The utility model does not relate to part to be realized as prior aries that maybe can adopt all same as the prior art such as control circuits.

Claims

1, a kind of cool in summer and warm in winter type stereo earphone, form by the connector that comprises left earphone, right earphone and connect left and right earphone, a described left side or right earphone are made up of sounding parts, fixed mount and sheath, it is characterized in that in sheath, the semiconductor refrigeration chip based on peltier effect is installed on the fixed mount, described semiconductor refrigeration chip is by the player power supply that links to each other with earphone and have positive and negative connection function, promptly described semiconductor refrigeration chip works in refrigerating state when just connecing, when reversal connection, described semiconductor refrigeration chip works in heated condition.
