Abstract

The utility model belongs to the field of household goods or radios. The scheme is presented for meeting the high requirements of ball fans and enabling ball fans to watch ball games on the spot and listen to relayed broadcasting from radio stations or television stations synchronously. The utility model is composed of a cap and a micro-type radio set. The cap adopts a baseball cap form. The radio set and earphones are placed in a pocket at the right side of the cap. Batteries for the radio set is place in a pocket at the left side of the cap. The radio set can be a frequency modulation band radio set, can be a frequency modulation band and amplitude modulation band radio set and can be a very-high frequency band radio set. As proved by tests, the utility model has the advantages of portability, wide purpose, novel form and low cost.

Description

Cabinet of radio set

The utility model belongs to daily necessities shoes cap or radio class, and it is specifically related to a kind of structure with wireless cap.

Vast sports enthusiast and football fans often like to watch ball match at existing field boundary, are seeing that Qiang Shangruo can hear simultaneously that the relay explanation of radio station or TV station can make something perfect even more perfect at last, can obtain further satisfying.Because from broadcasting, can hear introduction, also can hear the analysis of expert to the match situation to each sportsman.For this purpose, when watching a ball game again specially with on broadcast receiver then can feel trouble very.

The purpose of this utility model provides the most practical a kind of radio reception equipment, brings convenience for football fans, and it also has purposes widely certainly, and the people who can be the various ages uses and bring enjoyment.

By as above design, Cabinet of radio set provided by the utility model includes broadcast receiver and cap, and its concrete feature is in the side of cap the micro semiconductor broadcast receiver to be housed.

Micro-type receiver and used micro earphone machine are contained in the pocket of cap one side in this programme, and the used battery of transistor radio is to be contained in the pocket of cap opposite side.Its battery is to be contained in the battery case two No. 7 or No. 5 batteries.Its micro semiconductor broadcast receiver can be the broadcast receiver of an amplitude modulation section AM, also can be the broadcast receiver of frequency modulation section FM, can be the broadcast receiver that amplitude modulation section AM adds frequency modulation section FM, also can be the broadcast receiver of VHF band FM (TV1, TV2).

Adopt this programme can embody following superiority: 1. the Cabinet of radio set of this programme to be arranged, heard when can watch a ball game at the scene that the relay of radio station or TV station separates the situation analysis in the competition field of mediating a settlement, can obtain higher level satisfied; 2. this Cabinet of radio set is contained in broadcast receiver in the cap, and broadcast receiver is small and exquisite, carries with extremely easy to use; 3. it also can be the people service of other age bracket, the old man when the leisure stroll, when strolling in the park or enjoy the cool, can hear the broadcasting of opera, music and information at any time, students can be listened the broadcasting of foreign language and educational class, so its is of many uses; 4. it is simple in structure, cost is low, is convenient to make in batches promote the use of.

Fig. 1 is the outward appearance front view of this programme Cabinet of radio set.

Fig. 2 is its left view, and the situation of broadcast receiver and insert earphone is described.

Fig. 3 is its right view, and the situation of the battery that broadcast receiver is used is described.

Fig. 4 is the electrical schematic diagram of the micro-type receiver of amplitude modulation section AM.

Fig. 5 is the electrical schematic diagram of the micro-type receiver of frequency modulation section FM.

Fig. 6 is the electrical schematic diagram that amplitude modulation section AM adds the micro-type receiver of frequency modulation section FM.

Fig. 7 is the electrical schematic diagram of the micro-type receiver of VHF band FM (TV1, TV2).

The embodiment of existing accompanying drawings this programme.This Cabinet of radio set is made up of cap 1 and micro-type receiver 2, the adopt international standards pattern of baseball cap of type of its cap, its micro-type receiver and micro earphone machine 3 are placed in the pocket on cap right side, the used battery 4 of broadcast receiver is No. 7 or No. 5 batteries, and battery is contained in the battery case 5 and is placed in the pocket in cap left side.This micro-type receiver can make different forms: 1. the amplitude-modulation receiver that can make amplitude modulation section AM, as shown in Figure 4, it be adopt integrated circuit TEA5551T be the center match with other peripheral element through mixing, in put, detection, hang down to put and draw stereosonic output with power amplification, the coverage of its radio reception frequency is 550Kc～1605Kc, at ordinary times insert earphone is put in the pocket of adorning wireless right side, can directly be listened to the broadcasting in radio station during use; 2. when making the broadcast receiver of frequency modulation section FM, as shown in Figure 5, it is to be to match with peripheral element in the center with integrated circuit TDA7021T, make reception antenna with earphone cord, draw interesting to listen to stereo output through mixing, intermediate frequency filtering, amplitude limit amplification, low putting with power amplifier, the coverage of its radio reception frequency is 88MHz～108MHz, and it can listen to the relay of radio station or TV station; 3. be to adopt two integrated circuits 9642 and TDA7021 and two small-power amplifier tubes to form when broadcast receiver makes when frequency modulation adds the form of amplitude modulation, the audio signal of the frequency modulation that processes or the audio signal of amplitude modulation are exported after selecting to deliver to power amplification through a band switch, its feature is that the scope of listening to is wideer, uses unrestricted; 4. be to be the center when broadcast receiver being made VHF band FM (TV1, TV2) with integrated circuit TDA7021T, be equipped with other peripheral element through height put, in put, detection, low put, be processed into interesting to listen to sound behind the power amplifier, its TV1 covers 1～5 channel of TV, the frequency range of radio reception is 55.5MHz～108MHz, and TV2 covers 6～12 channels of TV, the frequency range of radio reception is 174MHz～224MHz, can be used for directly listening to the relay explanation of TV station.This product form is except that using for the football fan, and the old men can listen to music, drama, and students can be used to listen to foreign language or its educational class.The preproduction of this programme proves through test run: it has the advantages that easy to carry, of many uses, novel form, cost are low, can fully satisfy football fan and other all kinds of people's needs, therefore extensively is subjected to not see earlier person's welcome.
