Description

Solar garden lamp integrated with wireless sound production unit and table body for courtyard

Technical Field

The utility model relates to the field of lighting, especially, relate to an integrated solar garden lamp that has wireless sound production unit.

Background

With the continuous improvement of living standard, the requirements of people on environment are further improved. At present, landscape lamps and outdoor sound equipment are generally arranged in places such as landscape greenbelts, courtyard parks and the like, wherein the landscape lamps are used for lighting and decoration, and the outdoor sound equipment is used for playing background music or voice broadcast. The existing landscape lamp and outdoor sound equipment need to be powered and wired when being arranged, the installation is very inconvenient, and the traditional landscape lamp and outdoor sound equipment are independent individuals respectively.

The sound production process of the sound is similar to the sound production of a human body, and the sound production mechanism of the human body is as follows: the energy for controlling the amplitude of the vocal cords is provided by the pleuroperitoneal cavity, the vocal cords vibrate to generate sound, and the sound is weak and can be heard by a person only through the resonance of the pharyngeal cavity and the oral cavity. In this process, "resonance" (multiple reflections and mixing of sound in the oral cavity) is actually an amplification process of sound. Based on the principle, the resonance phenomenon is used in the design of the sound box to obtain the resonance type sound box, and the working principle is as follows: the loudspeaker is divided into two cavities by a partition board, the loudspeaker is arranged on the partition board, the cavity behind the loudspeaker is closed, namely a power assisting cavity or an energy storage cavity, and the cavity in front of the loudspeaker, namely a resonance cavity, is provided with a large sound releasing port, namely a semi-closed cavity. When the loudspeaker basin moves backwards, the air in the power-assisted cavity is compressed, and the air pressure in the cavity is large due to the fact that the cavity is closed; when the speaker basin moves forwards, compressed air expands, forward thrust of the speaker basin is increased, emitted sound is enhanced, the speaker basin simulates the human body, such as the thoracic cavity and abdominal cavity, the air storage capacity is large, the sound can be similar, the sound is reflected, mixed and energy superposed in the resonance cavity, abundant harmonic sound is carried out from the sound releasing port, the resonance process is completed, and the speaker basin simulates the human body, such as the oral cavity. Different sound effects can be obtained by adjusting the proportion of the boosting cavity, the resonance cavity and the sound releasing port, and the effect is similar to the effect that a person can control the sound by adjusting the size of the laryngeal muscles and the oral cavity.

Chinese patent (publication No. CN204393725U) discloses a computer desk with a rotary lamp, which includes a computer desk main body, wherein the computer desk main body includes a desktop element and four first support rods, each of the first support rods is disposed at a corner of a bottom surface of the desktop element, and a top surface of the desktop element further has symmetrical receiving grooves; and two rotating members, each of which is symmetrically and axially connected to the table top element and is respectively received in the receiving grooves; the rotating members respectively comprise a first rotating body and a second rotating body, wherein the first rotating body is provided with a sound box, the second rotating body is provided with a light-emitting element, and the sound box and the light-emitting element are connected with external electric energy through the same power line.

First, to the revolving light that this patent provided locates on the table main body and the table main body that has this revolving light, or to the garden lamp that adopts the formula of secretly installing among the prior art, owing to need set up the holding tank that is used for accomodating the revolving light on the desktop, inevitably there is great clearance between holding tank and the revolving light, and under long-term use especially in the great environment of outdoor this kind of wind and dust or weather, dust or debris can enter into in this clearance and be difficult to clean, and dustproof effect is not good in the dust prevention. When the device is used outdoors, a light and portable lighting device is often needed to provide light for illumination, but the device provided by the patent limits that the garden lamp and the table body can only be in an undetachable relation, which is not beneficial to diversified requirements of outdoor activities; the table body is large in size and can only be transported integrally, and the weight and size of the whole device increase the transportation difficulty for users.

Secondly, the garden lamp is one of outdoor lighting lamps, and is also called landscape garden lamp because of the characteristics of beautifying and decorating environment of diversity and aesthetic property. The garden lamp not only has the function of illumination, but also needs to be accompanied with the function of beautifying the environment. Existing solar garden lights are typically turned on all light sources together when night falls, thereby illuminating the garden. However, sometimes a user does not need to work or rest in a courtyard, at this time, the courtyard lamp only needs softer and weaker light to decorate the courtyard, and in modern urban life, various lamps with strong illumination are seen everywhere, although the lamps illuminate the night sky of the city like the daytime, too much strong illumination causes environmental light pollution, and the environmental light pollution brings many adverse effects and discomfort to the life of people.

In addition, especially in summer, mosquitoes are attracted by the light of the garden lamp, the mosquitoes crawling on the garden lamp are often seen, due to phototaxis of the mosquitoes, the mosquitoes approach the inner lamp tube, the lives of the mosquitoes such as flying moths are short, and when a user drinks tea under the garden lamp to chat, the phenomenon that exhausted mosquitoes fall under the lamp and possibly even fall into a water cup often occurs.

Meanwhile, most of the sound products of various brands entering the market are different in appearance and have no great difference in function, the sound equipment has the greatest characteristic that the sound equipment is based on moving coil type acoustic technology, sound emitted by a loudspeaker is propagated in all directions, and when people listen to music in a courtyard by using the sound equipment, noise interference can be caused to the surrounding environment due to the fact that sound is emitted in all directions, and rest of other houses around is further influenced.

Moreover, on the one hand, since the skilled person in the art is understood to be necessarily different from the examination department; on the other hand, since the present invention has been made in view of the above-mentioned circumstances, it is not intended to limit the scope of the invention to the details and the contents thereof, but rather, the present invention is not limited to the features of the prior art, but rather, the present invention is provided with all the features of the prior art and the right to increase the related art in the background art at any time according to the related regulations of the examination guidelines is retained.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides an integrated solar garden lamp that has wireless sound production unit includes the lamp stand at least, install in lighting device on the lamp stand and install in lamp shade on the lamp stand, be provided with solar cell panel, at least one stereo set subassembly in the lamp shade and lighting device, wherein, the stereo set subassembly with lighting device set up respectively in on the lamp stand, and make set up in the top of lamp shade solar cell panel with lamp shade, lamp stand constitute jointly the rear chamber of stereo set subassembly, and make the main diffusion direction of stereo set subassembly with lighting device's the incomplete coincidence of main light-emitting direction.

In the prior art, the sound component and the lighting device are often arranged in a separated mode, so that the back cavity volume of the sound component is too small, low frequency does not exist, and finally the sound quality is poor, and the sound is noisy in sense of audiences.
