Description

Cell-phone loudspeaker chamber device

Technical Field

The invention relates to the technical field of communication, in particular to a mobile phone horn cavity device.

Background

In the current trend of increasingly pursuing thin and large battery capacity in the market of electronic terminal products (including mobile phones and flat plates, but not limited to the two types of products), under the design environment atmosphere, functional performance of the electronic terminal products must be selected and removed, and the current practice in the industry is basically to shrink audio again and again, namely, the volume of a cavity (the size of lost volume and the tone quality) is a critical factor to meet the visual ultrathin effect of an ID, so that the design theory can indeed feel novel in the category of manpower.

In the whole scheme design of the terminal, an ID/MD engineer often considers that the ID perfection stands at the present position to consider the design, often adopts a super-extreme design mode to compress the space of the audio part so as to minimize the space to realize the ID, and the MD engineer also considers the space of the compressed acoustic part of the RF performance again while considering the ID, but often ignores the requirement of the electroacoustic part, and finally, the electroacoustic problem exists after the scheme is realized, and serious defects and problems exist in the electroacoustic part.

However, the design mode in the prior art is realized on the premise of losing sound quality and volume, and under the condition that the requirements of terminal consumers on electroacoustic are increasingly high, the current design is far from meeting the requirements of consumers, and the experience of the terminal is directly affected, so that the cognition and acceptance of the terminal users on products are unsatisfactory.

Disclosure of Invention

In order to solve the above problems, the present invention provides a speaker chamber device for a mobile phone, including: including last casing and lower casing to and loudspeaker body, loudspeaker body is arranged in between last casing and the lower casing, and its characterized in that, loudspeaker body installs on last casing, is formed with loudspeaker antechamber between the top of loudspeaker body and the last casing, is formed with from little gradually big approximate V style of calligraphy of gradual change in the direction that extends along the horizontal direction from one side of loudspeaker antechamber in the last casing and leads the sound passageway.

With such a structure, under the condition of insufficient congenital conditions, the limited space is fully utilized to realize infinite possibility, and the acoustic propagation way is changed by utilizing the acoustic propagation principle and mode to meet the demands of end users.

Preferably, the loudspeaker body is provided with sealing foam, and a loudspeaker front cavity is formed between the sealing foam and the loudspeaker body and between the sealing foam and the upper shell, and is communicated with the sound guide channel.

Further, the length of the horn-shaped sound guide channel is not more than 10mm.

The length of the sound guide channel 3 is required to be less than 10mm, the shorter the design is, the better the design is, and the purpose of the design is to reduce loss of sound volume in propagation and to form splayed diffusion transmission.

Preferably, the height of the horn front cavity is 0.4-0.9 mm.

Preferably, the height of the horn front chamber is 0.6mm.

Preferably, the included angle of the V-shape of the sound guide channel is 30 degrees.

Further, a sound guide channel which is approximately V-shaped and gradually increases from small to large is formed in the upper shell body in an upward extending mode from the front cavity of the loudspeaker.

Furthermore, the top of the upper shell forms a sound outlet part at the maximum horn mouth of the sound guide channel, and a plurality of sound outlet through holes are arranged on the sound outlet part.

Preferably, the included angle of the V-shaped of the sound guide channel is 45 degrees.

By means of the structure, the space problem of acoustics is fully considered in the process of structural stacking and design, and a certain space is reserved in the process of design to meet the basic requirement of achieving electroacoustic performance.

Compared with the prior art, the technical scheme of the invention has the following beneficial effects:

The advantages of this scheme:

1. The design scheme plays a very good role in electroacoustic effect, and the requirement of ID is better met under the condition of not losing the audio experience of the terminal;

2. the design of this scheme adopts the acoustic propagation mode principle to be similar to horn sound expansion principle, more does benefit to the propagation of sound, lets tone quality, better promotion of volume.

The design mode of the scheme plays an infinite role in utilizing limited space and has good expression.

Detailed Description

The present invention is described in detail below with reference to the accompanying drawings.

In order to solve the above problems, as shown in fig. 1-4, a preferred embodiment of the present invention provides a speaker chamber device of a mobile phone, comprising: including last casing 2 and lower casing 1 to and loudspeaker body 4, loudspeaker body 4 is arranged in between last casing 2 and the lower casing 1, and loudspeaker body 4 installs on last casing 2, is formed with loudspeaker antechamber 6 between the top of loudspeaker body 4 and the last casing 2, is formed with from little gradually the sound channel 3 of approximate V style of calligraphy that gradually increases in the direction that extends along the horizontal direction from one side of loudspeaker antechamber 6 in the last casing 2.

In this embodiment, be provided with sealed bubble cotton on the loudspeaker body, form loudspeaker front chamber between sealed bubble cotton and loudspeaker body and the last casing, loudspeaker front chamber communicates with each other with leading the sound passageway.
