Problems solved by technology

However, in the external connection terminal having the spring piece described in this publication, there are the following problems: poor conduction caused by the contact of the spring piece falling off due to vibration, poor conduction caused by plastic deformation of the spring piece, Poor conduction caused by dirt on the contact of the chip, etc.
Therefore, there is a problem that space saving cannot be realized
In addition, due to the above-mentioned operation, there is a problem that the workability is poor.

Embodiment approach 1

[0045] First, the configuration of the speaker according to Embodiment 1 of the present invention will be described.

[0046] refer to figure 1 , the speaker 1 mainly has a box body 2 and a speaker unit 10 . A speaker unit 10 is accommodated in the internal space 4 of the housing 2 . The speaker unit-side terminal 21 of the speaker unit 10 is electrically connected to one end of the box-side terminal 22 of the box 2 by soldering. It should be noted that, in figure 1 In FIG. 2 , the solder that joins the speaker unit-side terminal 21 and one end of the box-side terminal 22 is not shown for ease of viewing. Likewise, in Figure 4 and Figure 5 In FIG. 2 , the solder that joins the speaker unit-side terminal 21 and one end of the box-side terminal 22 is not shown.

[0047] The case 2 is composed of a first case part 2a and a second case part 2b so as to be separable. The speaker unit 10 is attached to the first box portion 2a. In the state where the speaker unit 10 is acc...

Embodiment approach 2

[0104] First, the configuration of the portable information terminal of this embodiment will be described. In this embodiment, a portable information terminal including the speaker of Embodiment 1 will be described.

[0105] refer to Figure 12 and Figure 13 , the portable information terminal 100 in the present embodiment is a portable telephone, and it mainly includes an upper frame body 101, a display portion 102, a sound emission hole 103, a hinge portion 104, a lower frame body 105, operation buttons 106, number buttons 107, display part 111, sound emission hole 112, and the speaker of Embodiment 1 which are not shown.

[0106] refer to Figure 12 A display unit 102 is provided on the surface of the upper housing 101 . A sound emission hole 103 is formed on one end side of the surface of the upper housing 101 . A hinge portion 104 is formed on the other end side of the upper housing 101 . A hinge portion 104 is formed on one end side of the lower housing 105 . The...

Abstract

A speaker has a speaker unit and a box. The speaker unit has a speaker unit side terminal. The box includes a casing having an internal space, and a box side terminal arranged in the casing so as to be in close contact with the casing. Under the condition that the speaker unit is housed in the internal space, a first terminal serving as one of the speaker unit side terminal and the box side terminal has a projection, a second terminal serving as the other thereof surrounds and sandwiches an outer periphery of the projection from at least both sides, and the first terminal and the second terminal are electrically connected with soldering. Thus, it is possible to obtain the speaker which can improve workability on a connection between the speaker unit and the box and save a space, and the portable information terminal provided with the speaker.

Description

technical field [0001] The present invention relates to a speaker and a portable information terminal, and more particularly to a speaker having a speaker unit and a cabinet, and a portable information terminal equipped with the speaker. Background technique [0002] Speakers are mounted on portable information terminals such as mobile phones, smart phones, PDAs (Personal Digital Assistants), game machines, and personal computers. In recent years, high sound quality has also been demanded for speakers mounted on portable information terminals. [0003] When the sound from the back of the diaphragm of the speaker returns to the surface, the sound from the surface and the sound from the back interfere and cancel each other out, so the sound quality deteriorates. Since the interference is large in the low-frequency region where the frequency is low, the sound quality of the sound in the low-frequency region especially deteriorates. In order to suppress the interference of the...
