Abstract

An audio playing device, comprising: a terminal protective sleeve; a terminal rear cover, having an external side fixed to an inner surface of the terminal protective sleeve; a loudspeaker provided within the terminal protective sleeve; a metal contact provided on a first region of the inner surface and capable of connecting to the loudspeaker. The terminal rear cover has a hollow part corresponding to the first region, and after the terminal rear cover is assembled onto a terminal, the metal contact contacts an output end of a motherboard in the terminal.

Description

Audio external device

Technical field

This paper deals with the application fields of terminal peripheral products, especially an audio external device.

Background technique

At present, terminals, especially mobile phones, are an indispensable tool for everyone's indispensable life communication. With the development of technology and the improvement of people's living standards, the functional requirements for mobile phones are increasing. In China, especially the elderly, I hope that the louder the phone, the better, so listening to radio, drama and music is more convenient and lively.

However, most of the sounds of the mobile phone speakers are too small, and the loudness and sound quality of the sound are difficult to achieve the effect of the external traditional large speakers. This is not only inconvenient for the user's use, but also a waste of the mobile phone hardware application. Make the phone speaker perform its performance effectively.

Summary of the invention

The embodiment of the invention provides an audio external release device, which can improve the external release effect of the terminal.

An audio external device includes:

Terminal protection cover;

a rear cover of the terminal, the outer side of which is fixed to the inner surface of the terminal protective cover;

a speaker disposed in the terminal protective cover;

a metal contact piece disposed on the first region of the inner surface and connectable to the speaker;

The terminal back cover has a hollow portion corresponding to the first area. After the terminal back cover is assembled on the terminal, the metal contact piece is in contact with an output end of the internal motherboard of the terminal.

Optionally, the metal contact is connected to the horn by a wire.

Optionally, the outer side of the terminal back cover is adhered and fixed to the inner surface of the terminal protective cover by super glue.

Optionally, the terminal protection sleeve is a cortical material or a rubber material.

Optionally, the terminal protection sleeve has an inner cavity, and the speaker is disposed in the inner cavity. And protruding to the outer surface of the terminal cover to form an acoustic.

Optionally, the metal contacts are two.

Optionally, the terminal is a mobile phone.

The audio external device of the embodiment of the invention can provide protection for the mobile phone as a mobile phone case, and the built-in speaker can improve the external release effect of the mobile phone, and thus has high practical value.

BRIEF abstract

1 is a schematic structural diagram of an audio external device according to an embodiment of the present invention;

2 is a schematic diagram of a speaker of an audio external device according to an embodiment of the present invention.

Embodiments of the invention

The detailed description will be made below in conjunction with the accompanying drawings and specific embodiments.

The present invention provides an audio external device, as shown in FIG. 1 , which includes:

Terminal protection cover 1;

The rear cover 2 of the terminal is fixed to the inner surface of the terminal cover 1;

a speaker 4 disposed in the terminal protection cover 1;

a metal contact piece 6 disposed on the first region of the inner surface and connectable to the horn 4;

The terminal back cover 2 has a hollow portion 7 corresponding to the first region, that is, the metal contact piece 6 on the inner surface of the mobile phone case 1 can pass through the mobile phone back cover 2. The audio external device of the embodiment of the present invention is equivalent to a combination of a terminal back cover 2 (which may also be a battery back cover) and a terminal protection cover 1. After the terminal is closed on the rear cover 2, the output end of the internal motherboard of the terminal (such as the output pin) just in contact with the metal contact 6, so that the user controls the speaker 4 through the terminal internal program for external release.

Optionally, the metal contact 6 is connected to the horn 4 via a lead 5 . The outer side of the terminal back cover 2 can be adhered and fixed to the inner surface of the terminal protective cover 1 by super glue.

In addition, in order to have a good tactile experience for the user, the terminal protection cover may be a cortical material or a rubber material.

In addition, in order to increase the contact effect between the metal contacts 6 and the output terminals of the internal motherboard of the terminal, the metal contacts 6 of the embodiment may be two.

In addition, in order to make the device of the embodiment have a good external release effect, as shown in FIG. 2, the terminal protection sleeve 1 has an inner cavity 3, and the speaker 4 is disposed in the inner cavity 3, and The outer surface of the terminal cover protrudes to form an acoustic.

It can be seen that the device of the present invention can be used as a protective cover for the terminal in general. When it is necessary to use the terminal to put music outside, the built-in speaker of the terminal protection sleeve can be used to enhance the loudness and sound quality of the mobile phone speaker, and solve the problem that the external effect of the terminal is poor.

The terminal in the embodiment of the present invention may be a mobile phone, or may be another handheld terminal or mobile terminal such as a tablet computer.

Industrial applicability

The audio external device of the embodiment of the invention can be used as a terminal protection sleeve, and the built-in speaker can improve the external discharge effect of the terminal, and thus has high practical value.
